In the Philippines, a sales commission can still be legally enforceable even without a written contract. Many commission arrangements begin informally: a verbal agreement, a series of text messages, a long-running practice of payment, or instructions given by an owner, manager, or principal. When commissions go unpaid, the absence of a formal written agreement does not automatically mean there is no legal claim.

What matters is whether the claimant can prove that a commission arrangement existed, what its terms were, and that the commission was already earned under that arrangement. Philippine law generally allows contracts to be formed by consent alone, unless a specific law requires a particular form. For most commission claims, no special form is required. A contract may therefore be oral, implied from conduct, or shown through surrounding documents and business practice.

This article explains the legal basis, evidence, remedies, procedure, defenses, and practical strategy for claiming unpaid sales commissions in the Philippine setting.

1. Can a commission agreement exist without a written contract?

Yes.

Under Philippine civil law, contracts are generally perfected by mere consent. As a rule, a contract is binding once the parties agree on the essential terms, even if nothing was signed. In practical terms, this means a commission arrangement may arise from:

an oral promise to pay a percentage or fixed amount per sale;
a course of dealing where commissions were regularly paid before;
emails, chat messages, Viber or WhatsApp exchanges, text messages, or internal memos;
payroll records, accounting entries, sales reports, or commission statements;
acts showing both parties understood that commissions would be paid.

A written contract is the strongest evidence, but it is not always legally necessary.

The real issue in a commission dispute is usually proof, not validity.

2. What is a sales commission in Philippine practice?

A sales commission is compensation tied to the procurement, generation, or closing of sales. It may be structured as:

a percentage of gross sales;
a percentage of net sales;
a percentage of profit;
a fixed amount per account, booking, collection, or closed deal;
a tiered incentive depending on quota;
an override commission based on team sales;
a commission only after collection from the client;
a recurring commission for renewals or repeat business.

The exact structure matters because a claim depends on proving not only that commissions were promised, but also how they were computed and when they became due.

3. Sources of law that may support the claim

A claim for unpaid sales commissions in the Philippines may arise under several bodies of law, depending on the relationship between the parties.

A. Civil Code

The Civil Code is the main legal foundation for unwritten agreements and unpaid money claims. Relevant principles include:

contracts are obligatory once perfected;
obligations arising from contracts have the force of law between the parties;
a person who has performed under an agreement may demand what is due;
unjust enrichment is not allowed;
a party who acts in bad faith or breaches an obligation may be liable for damages;
receipts, business records, messages, and conduct may be used to prove the arrangement.

B. Labor law

If the claimant is an employee, commissions may be treated as part of wages or compensation, depending on the arrangement. Labor law becomes important for:

recovery of unpaid commissions;
illegal deductions or withholding;
final pay disputes;
money claims before labor tribunals;
prescription periods for labor claims;
possible constructive dismissal or illegal dismissal issues if nonpayment is tied to termination.

C. Commercial and agency principles

If the claimant is not an employee but an independent sales agent, broker, commission-based representative, or distributor-related salesperson, the matter may fall more squarely under civil or commercial law rather than labor law.

D. Evidence law and procedural rules

Because there is no written contract, success often depends on the ability to prove the agreement through admissible evidence, including electronic evidence.

4. Employee or independent contractor: why this matters

One of the first legal questions is whether the claimant was:

an employee entitled to invoke labor remedies; or
an independent contractor/agent whose claim is mainly civil in nature.

This matters because it determines:

where to file the case;
what procedure applies;
whether labor standards and labor tribunals are available;
how attorney’s fees, damages, and interest may be handled;
the defenses the other side may raise.

A. Indicators of employment

Philippine law commonly looks at the “four-fold test,” especially the power of control, to determine employment. Indicators include:

the company hired the salesperson directly;
the company paid salary in addition to commission;
the company controlled work methods, schedule, territories, and reporting;
the salesperson used company systems and was treated as staff;
taxes, payroll, IDs, HR rules, and disciplinary policies applied;
termination required company approval.

If the claimant was effectively under the company’s control, a labor forum may be proper even if the arrangement was called “commission-only” or “agency.”

B. Indicators of independent agency or contractor status

Factors suggesting a civil case instead of a labor case include:

the salesperson controlled how to obtain clients;
there was no fixed schedule imposed;
payment was purely commission-based per closed deal;
the salesperson handled multiple principals;
there was no payroll treatment typical of employees;
the principal cared more about results than the manner of work.

Labels do not control. Substance does.

5. Is an oral commission agreement enforceable?

Usually yes.

An oral agreement is generally enforceable if the essential elements of a contract are present:

consent: both sides agreed;
object: the services or sales activity;
cause/consideration: the commission in exchange for procuring sales.

The difficulty is proving the agreement and its precise terms. In commission disputes, courts and tribunals often focus on questions such as:

Was a commission really promised?
By whom?
At what rate?
On what base: gross sale, net sale, collected amount, profit?
When is it earned: at booking, delivery, invoicing, or collection?
Were quotas or conditions attached?
Were returns, cancellations, or bad debts excluded?
Was the claimant the procuring cause of the sale?

6. What evidence can prove unpaid commissions without a written contract?

This is the heart of the case.

A claimant without a signed contract must build the agreement from surrounding evidence. In Philippine practice, useful evidence may include the following.

A. Electronic communications

text messages;
emails;
Messenger, Viber, WhatsApp, Telegram, Slack, or similar chats;
voice notes or transcribed calls where lawful and admissible;
calendar invites and meeting notes discussing commission terms.

These may show the rate, conditions, acknowledgment of sales, or promises to pay.

B. Proof of prior payments

Previous commission payments are powerful evidence because they show the arrangement actually existed. Useful documents include:

payslips;
bank transfers;
GCash or other digital wallet records;
commission summaries;
payroll breakdowns;
accounting vouchers;
debit/credit memos;
official receipts or acknowledgment receipts.

If the principal paid commissions before under the same pattern, that course of dealing strongly supports the existence of the agreement.

C. Sales records

invoices;
sales orders;
purchase orders;
contracts with customers;
delivery receipts;
collection records;
CRM entries;
booking reports;
pipeline reports;
account assignment sheets;
territory lists.

These can show that sales occurred and that the claimant brought in or handled them.

D. Internal company records

commission schedules;
compensation plans;
onboarding materials;
sales targets or incentive memos;
budget approvals;
board or management approvals;
finance emails discussing unpaid commissions;
spreadsheets prepared by HR, finance, or sales managers.

E. Witness testimony

Witnesses may include:

supervisors;
co-salespersons;
finance or payroll personnel;
customers who dealt through the claimant;
officers who acknowledged the arrangement.

A credible witness can help prove oral terms and business practice.

F. Conduct of the parties

Sometimes conduct says more than a document. Examples:

the claimant was assigned leads or territory with the understanding of commission;
the company regularly asked for sales updates and computed payouts;
management promised to release commissions once collections came in;
the company withheld only some commissions, not all.

G. Admissions

Any admission by the other side is highly useful, such as:

“We will release your commission next month.”
“Finance is still computing your percentage.”
“Your account already closed, but collection is pending.”
“You are not entitled because you resigned before payout.”

Such statements often concede that the arrangement existed and narrow the dispute to timing or conditions.

H. Electronic evidence considerations

Because many modern commission arrangements are proved through chats and emails, preserve:

screenshots with dates and names visible;
original files, not just cropped images;
email headers where possible;
exported chats or message histories;
metadata where available.

Authenticity matters. The cleaner the chain of evidence, the better.

7. What exactly must be proved?

A strong commission claim usually requires proof of the following:

A. There was a commission agreement

Even if unwritten, show that both parties agreed to pay commissions.

B. The claimant performed

Show that the claimant actually generated, procured, handled, or materially caused the sale.

C. The triggering event happened

Depending on the arrangement, this may be:

booking of the order;
signing of the client contract;
delivery of goods;
invoicing;
customer payment/collection;
passage of warranty or return period.

D. The amount is reasonably determinable

The claim should not be vague. A claimant should present:

the agreed rate;
the sales covered;
the base amount used;
deductions or exclusions, if any;
the total due.

E. Demand was made and payment was refused or ignored

A prior written demand is not always required to prove the debt itself, but it is important for:

showing the claim was asserted;
establishing delay;
supporting interest and damages arguments;
clarifying the exact amount demanded.

8. Common situations where commissions are denied

Commission disputes often arise in recurring fact patterns.

A. “There was no written contract, so nothing is due.”

Not necessarily true. Lack of a written contract is not an automatic defense if the agreement can be proven otherwise.

B. “You were only entitled after full collection.”

This may be a valid defense if that was truly the agreed condition. The claimant should check prior practice. If commissions were historically paid on booking or invoicing, that practice may defeat the defense.

C. “The sale was a team effort, not yours.”

Then the issue becomes whether the claimant was the effective or procuring cause, whether accounts were assigned, and whether shared commissions were the practice.

D. “You resigned before payout.”

This is very common. The answer depends on the actual arrangement. If the commission was already earned before resignation, many employers or principals cannot simply forfeit it unless a lawful and provable forfeiture rule clearly existed and is enforceable.

E. “The customer later cancelled or did not pay.”

This may matter if the commission was contingent on final collection or if returns/cancellations were excluded. Again, prior practice and proof of agreed conditions are key.

F. “Management never approved the commission.”

If the person who promised the commission had apparent or actual authority, or if the company ratified the arrangement by previous payments, the defense may fail.

G. “You were not an employee.”

That may affect forum and theory, but not automatically the existence of a money claim.

9. The “earned commission” issue

A central question is: when is a commission earned?

Without a written contract, this is determined from:

oral agreement;
company practice;
prior payouts;
internal compensation policies;
the nature of the industry.

Possible rules include:

commission earned upon sale closing;
commission earned only upon delivery;
commission earned only upon actual customer payment;
commission earned in stages;
commission subject to clawback for returns or default.

If nothing clearly shows collection was required, the claimant may argue that commission was earned once the sale was procured and accepted. If prior commissions were always released only after customer payment, the principal will likely argue collection was an implied condition.

10. Can commissions be claimed after resignation or termination?

Often yes, if already earned.

The fact of resignation, termination, or end of engagement does not automatically erase commissions already accrued. The claimant should distinguish between:

earned but unpaid commissions, and
future contingent commissions not yet vested.

Earned but unpaid commissions

These are generally more recoverable. The claimant should prove the sale was already booked, completed, or collected under the parties’ practice before separation.

Future or contingent commissions

These are harder to recover if important conditions had not yet happened by the time the relationship ended.

Red flags in employer/principal policies

Some businesses impose blanket forfeiture rules like “no payout after resignation.” These are not always enforceable, especially if they operate unjustly against commissions already earned. The legality of such a rule depends on the specific facts, status of the worker, and how the arrangement was actually administered.

11. Where should the claim be filed?

This depends mainly on the relationship and nature of the claim.

A. If the claimant is an employee

A money claim for unpaid commissions is commonly brought through the labor dispute system. This is often done through the appropriate labor forum handling money claims and employer-employee disputes.

This route is usually appropriate when the claimant was under company control and commissions formed part of compensation.

B. If the claimant is an independent contractor, agent, or broker

The claim is usually filed as a civil action for sum of money, damages, specific performance, or collection, depending on the facts and amount involved.

C. If there is uncertainty over status

In real disputes, the parties often fight first over whether an employer-employee relationship exists. That threshold issue can determine whether the labor forum or regular courts have jurisdiction.

Choosing the wrong forum can delay the case, so classification is critical.

12. What remedies may be claimed?

A claimant may seek one or more of the following.

A. Payment of unpaid commissions

The principal relief is the amount actually due.

B. Legal interest

Interest may be recoverable, especially after demand or from the time the amount becomes due, depending on how the obligation is characterized and proved.

C. Damages

Possible in proper cases:

actual damages if the claimant can prove specific loss;
moral damages in exceptional cases involving bad faith, fraud, oppressive conduct, or analogous circumstances;
exemplary damages where the conduct was wanton or abusive;
temperate damages in limited settings where some loss is certain but hard to quantify precisely.

Bad faith matters. Mere nonpayment does not automatically justify moral or exemplary damages.

D. Attorney’s fees

These are not granted as a matter of course. They may be recoverable where allowed by law, contract, labor rules, or when the other side’s unjustified act compelled litigation.

E. Accounting

Where the principal controls the sales data and the commission cannot be computed without disclosure, the claimant may seek an accounting or compel production of records in the proper proceeding.

13. How much can be claimed?

The claimant should prepare a careful computation. This usually includes:

each sale covered by the claim;
date of sale or closing;
customer name;
invoice/PO/reference number;
sales amount;
collection date, if relevant;
agreed commission rate;
gross commission;
deductions, returns, or exclusions, if any;
net commission due;
date the amount became payable;
interest, if claimed.

A vague claim like “they owe me a lot of commissions” is weak. A spreadsheet with documentary backup is far stronger.

14. What if the exact rate cannot be proven?

That makes the claim harder, but not always impossible.

Possible fallback theories include:

proof of the usual rate paid in prior transactions;
proof of standard company practice;
proof of industry custom, though this alone is usually weaker;
quantum meruit or unjust enrichment arguments, especially where services were clearly rendered and benefited the principal.

Still, a commission case is strongest when the rate can be shown through prior payments, messages, or internal records.

15. Unjust enrichment as a fallback theory

Where a claimant substantially helped secure sales and the principal benefited, Philippine law’s anti-unjust-enrichment principle may help prevent a party from retaining benefits without paying what is due.

This is not a substitute for proof of contract when a contract can be shown, but it can support the fairness of recovery when:

the principal accepted the benefit of the claimant’s work;
payment was expected;
the principal knew compensation was due;
refusal to pay would be inequitable.

This is especially useful where the principal denies the precise contract terms but the evidence strongly shows that compensated sales work was performed and accepted.

16. Importance of demand letter

A formal demand letter is often the most practical first step.

It should clearly state:

the basis of the commission arrangement;
the sales covered;
the computation;
supporting facts and attached proof;
the amount demanded;
a deadline for payment;
notice that legal action may follow.

Why it matters

A demand letter can:

prompt settlement;
create a paper trail;
lock in the claimant’s theory of the case;
trigger default or delay arguments;
elicit an admission from the other side.

Tone

It should be firm, factual, and specific, not emotional or vague.

17. What should be attached to the demand?

Useful attachments include:

commission computation sheet;
copies of invoices or sales orders;
screenshots of messages;
proof of prior commission payments;
emails acknowledging the sales or commission;
customer contracts or delivery records;
resignation or clearance documents, if relevant;
payroll records or payslips;
IDs, organizational chart, or memos showing status and authority.

18. Prescription: how long does the claimant have?

Time limits are very important.

The exact prescriptive period depends on the nature of the claim and whether it is framed as:

a labor money claim;
an action based on oral contract;
a written acknowledgment of debt;
a quasi-contract or unjust enrichment claim;
a claim tied to an employer-employee relationship.

Because prescriptive periods can vary depending on the legal theory and forum, a claimant should not delay. In practice, the safest approach is to act as soon as nonpayment becomes clear.

Delay creates several problems:

records disappear;
chats are deleted;
witnesses leave;
sales data becomes harder to obtain;
defenses based on prescription become stronger.

19. How do labor and civil approaches differ?

A. Labor route

This is generally more favorable when there is a real employer-employee relationship. It may offer:

a specialized forum for money claims;
procedures designed for labor disputes;
access to labor-related remedies;
a framework that looks beyond labels like “agent” or “consultant.”

But the claimant must first establish employment if disputed.

B. Civil route

This is the usual path for independent agents, brokers, and non-employees. The claim is treated more as a contractual or collection case. The court will closely examine:

the oral agreement;
proof of sales and performance;
computation;
demand and refusal;
credibility of records and witnesses.

20. What defenses are commonly raised by employers or principals?

A claimant should expect these.

A. No agreement

Response: show messages, prior payments, witness testimony, and business practice.

B. No authority of the person who promised commission

Response: show apparent authority, prior approvals, ratification, or company knowledge.

C. Commission not yet earned

Response: prove the trigger event occurred, or that the company’s past practice treated the sale as already commissionable.

D. Amount is uncertain

Response: provide an itemized computation with source documents.

E. Claimant did not cause the sale

Response: prove lead generation, negotiation, customer relationship, or assignment of account.

F. Customer has not fully paid

Response: show the agreement did not require collection, or that collection has already happened.

G. Resignation or termination forfeited commission

Response: argue vested commissions cannot be defeated by an unfair after-the-fact forfeiture rule.

H. Independent contractor, not employee

Response: if using labor route, prove control and other employment indicators.

I. Prescription

Response: determine the correct legal theory and show the claim was timely filed.

J. Waiver, quitclaim, or release

Response: scrutinize whether the quitclaim specifically covered commissions, whether it was voluntary, and whether the amount paid was reasonable and informed.

21. Quitclaims and waivers

Many commission disputes surface after an employee signs a quitclaim or clearance.

A quitclaim does not always bar a valid claim. Its effect depends on factors such as:

whether it clearly mentioned commissions;
whether the employee understood what was being waived;
whether the settlement was fair and voluntary;
whether there was fraud, coercion, or unequal bargaining pressure;
whether the waiver was contrary to law or public policy.

A generic clearance form is not always enough to extinguish a legitimate unpaid commission claim, especially if the commissions were never disclosed or computed.

22. What if the company keeps the records?

This is common. Employers and principals often control:

invoices;
collection ledgers;
commission tables;
payroll entries;
CRM logs.

A claimant should still gather what is available from personal records, but in litigation or formal proceedings the claimant may seek production of relevant documents. Even before filing, the demand letter may ask for:

statement of account for commissions;
commission computation;
sales and collection records for named accounts;
payroll or payout history;
policy documents governing commissions.

Where the other side withholds records despite prior acknowledgment that commissions are due, that conduct may strengthen the inference that the claim is legitimate.

23. Best evidence to gather before filing

Before sending demand or filing a case, the claimant should organize evidence in this order:

1. Proof the arrangement existed

Messages, emails, onboarding docs, supervisor instructions, prior payouts.

2. Proof of the rate or formula

Chats, memos, previous commission sheets, payroll records.

3. Proof of covered sales

Invoices, POs, customer contracts, delivery receipts, collection records.

4. Proof the claimant caused the sales

Lead history, client communications, account assignment, meeting records.

5. Proof commissions were due and unpaid

Follow-up messages, finance confirmations, unpaid payout sheets, final pay records.

6. Proof of demand

Demand letter and proof of receipt.

24. Strategy when the terms are incomplete or messy

Many real-world cases do not have clean terms. In that situation:

use the most consistent pattern from prior dealings;
rely on the company’s own historical payouts;
identify the minimum indisputable amount;
separate clearly earned commissions from disputed future incentives;
do not overstate the claim.

A moderate, evidence-backed claim is usually more credible than an inflated one.

25. Can criminal liability arise?

Usually, unpaid commissions are primarily a civil or labor matter, not a criminal one. Nonpayment alone is not ordinarily estafa or theft. Criminal theories generally require specific elements beyond mere breach of promise.

Still, separate criminal issues may arise in unusual facts involving:

falsified records;
fraudulent diversion of commissions;
misappropriation of funds entrusted for payout;
fabricated deductions or ghost reversals.

But in the ordinary unpaid commission dispute, the main remedy is collection through the proper forum.

26. Tax and payroll considerations

Commission claims sometimes intersect with tax and payroll issues.

Questions that may arise include:

Were commissions treated as wages?
Were withholding taxes applied?
Were they booked as incentives, fees, or payroll items?
Were government contributions handled consistently with employee status?

These details can help prove the true nature of the relationship. For example:

payroll treatment may support employee status;
official accounting entries may prove the debt;
repeated withholding or payslip entries may show commission as part of compensation.

Tax treatment does not fully determine legal status, but it can be persuasive evidence.

27. Special issue: commission-only workers

Some people work on a commission-only basis with little or no fixed salary. This creates two recurring legal questions:

Are they employees despite commission-only pay?
If so, are the commissions part of wages or a separate incentive structure?

In Philippine practice, being paid purely by commission does not automatically mean the person is not an employee. Control and the overall relationship still matter.

So a commission-only salesperson may still bring a labor claim if the factual setup shows employment.

28. Special issue: house accounts, reassignments, and poaching disputes

Disputes often happen when:

an account is reassigned after the salesperson developed it;
another salesperson closes the transaction;
management takes over late-stage negotiations;
the customer renews directly with the company.

The legal question becomes whether the claimant was the procuring cause of the sale or renewal. Helpful evidence includes:

who opened the account;
who handled negotiations;
who secured approvals;
who maintained the relationship;
company rules on account ownership and splits.

Without clear written rules, prior practice becomes very important.

29. Special issue: commissions tied to collection

Many Philippine businesses only pay commissions after actual collection from the client. This arrangement is not unusual. But if the principal invokes this rule, it should be supported by actual proof, such as:

prior commission history showing payouts only after collection;
internal policies consistently applied;
oral instructions repeatedly acknowledged by the claimant.

If there is evidence that commissions were sometimes paid before collection, the supposed rule may be attacked as inconsistent or selectively invoked.

30. Special issue: withholding final pay because of commission dispute

Sometimes the employer withholds final pay, or refuses to release earned commissions unless the worker signs a waiver. That can create additional legal issues, especially in an employment setting.

A claimant should separate:

unpaid salary/final pay;
unused leaves, if any;
earned commissions;
incentives not yet vested;
disputed post-employment claims.

Bundling everything into a clear accounting helps avoid confusion.

31. Practical drafting of the claim

A strong legal complaint or demand should answer six questions plainly:

Who promised the commission?
What was promised?
How was it normally computed and paid?
What sales earned the commission?
Why is it already due?
How much exactly remains unpaid?

If those six are answered with documents, the absence of a formal written contract becomes much less damaging.

32. Sample theory of the case

A typical claimant theory may look like this:

The claimant was engaged as a salesperson for the respondent. Even without a formal written commission agreement, the parties agreed and consistently acted on a compensation structure under which the claimant received a fixed commission percentage for sales he procured. This arrangement is proven by prior commission payments, manager communications, sales records, and finance acknowledgments. The claimant successfully generated specific accounts and sales, the contractual trigger for commission payment occurred, and the respondent benefited from those transactions. Despite repeated demands, the respondent withheld payment without lawful basis. The unpaid commissions are therefore due, with applicable interest and damages where warranted.

That is the general structure, whether the claim is framed in labor or civil terms.

33. Common mistakes claimants make

A. Waiting too long

Delay weakens evidence and may trigger prescription issues.

B. Failing to preserve digital proof

Old chats disappear. Export them early.

C. Not computing the claim carefully

A precise, supported amount is far better than a rough estimate.

D. Mixing earned commissions with hoped-for future commissions

Only vested or provably due amounts should be emphasized first.

E. Ignoring status issues

Employee versus contractor can decide forum and outcome.

F. Signing broad quitclaims without review

This can complicate recovery later.

G. Assuming “no written contract” means “no case”

That is often wrong.

34. Common mistakes companies or principals make

A. Assuming oral arrangements are unenforceable

They often are enforceable if proved.

B. Applying unwritten forfeiture rules only after the relationship sours

This looks self-serving and may not hold up.

C. Inconsistent commission practice

Paying one way before, then inventing a different rule later, creates exposure.

D. Poor records

Lack of documentation can hurt both sides.

E. Letting unauthorized managers promise commissions

This creates disputes over authority and ratification.

35. Settlement considerations

Many commission disputes settle once the evidence is organized. Settlement is often easier when the claimant presents:

a concise factual narrative;
a table of unpaid commissions;
supporting documents in order;
a reasonable position on disputed items.

A claimant should often separate:

non-negotiable earned commissions from
arguable or contingent commissions.

That makes negotiation more realistic.

36. Suggested structure of a demand letter

A practical demand letter usually contains:

Heading and identification

Identify the parties and relationship.

Statement of the agreement

Explain the oral or implied commission arrangement.

Statement of performance

List the sales/accounts procured.

Statement of breach

Explain what became due and remains unpaid.

Computation

Attach a commission schedule.

Demand

Demand payment within a fixed period.

Reservation of rights

State that failure to pay may lead to filing of the proper labor or civil action.

37. How courts and tribunals typically view these cases

Although each case turns on its own evidence, decision-makers usually care about a few recurring themes:

consistency of the claimant’s story;
existence of corroborating documents;
prior actual payment of commissions;
whether the amount is verifiable;
whether the claimant truly caused the sale;
whether the principal acted consistently and in good faith;
whether the dispute is really about existence, computation, timing, or forfeiture.

A claimant who can show a long pattern of recognized commissions is usually in a far stronger position than one relying only on bare verbal assertions.

38. Bottom line

In the Philippines, unpaid sales commissions may be claimed even without a written contract. The law does not generally require a written agreement for a commission arrangement to be valid. An oral agreement, an implied arrangement, or a long-standing practice can be enforceable.

The real challenge is proof.

A successful claim usually depends on showing:

that a commission agreement existed;
that the claimant performed and generated the sale;
that the commission was already earned under the parties’ actual arrangement;
that the amount can be computed with reasonable certainty;
that payment was demanded but withheld.

Where the claimant is an employee, labor remedies may be available. Where the claimant is an independent agent or broker, civil remedies are usually appropriate. In either case, the absence of a signed contract is not the end of the matter.

The strongest cases are built from digital communications, prior payments, sales records, witness testimony, and a disciplined computation of the amount due.

Important caution

Philippine commission disputes are highly fact-specific. The correct forum, prescriptive period, and legal theory can change depending on whether the claimant is an employee, agent, broker, consultant, or contractor, and on when the commission was considered earned. For that reason, any actual case should be assessed against its exact documents, messages, and payment history before filing.
