When a supplier delivers fewer items than you ordered but still insists on full payment, the safest move is to treat it as a contract performance problem, not just a customer-service issue. Under Philippine law, a seller’s duty to deliver and a buyer’s duty to pay are usually reciprocal: you pay because the supplier delivers what was agreed. If the delivery is incomplete, you should document the shortage immediately, avoid signing documents that make it look like the order was complete, send a written notice, and choose the proper remedy depending on whether you are a consumer, a business buyer, or a party to a larger supply contract.

Is an Incomplete Delivery a Breach of Contract?

Yes, it can be.

A supplier commits a breach when it fails to deliver the quantity, kind, quality, packaging, accessories, documents, or delivery schedule agreed in the purchase order, quotation, invoice, contract, chat messages, or course of dealing between the parties.

Common examples include:

You ordered 100 sacks of rice but only 80 were delivered.
You paid for 50 boxes of tiles but 10 boxes were missing.
The supplier delivered the main equipment but not the required accessories.
The order arrived in several batches, but the final batch never came.
The supplier substituted cheaper or different items without your consent.
The supplier delivered goods to the wrong address, then demanded payment anyway.
The supplier claims the delivery was complete because the rider or warehouse staff signed a receipt, even though the items were not actually counted.

Under the Civil Code, contracts have the force of law between the parties and must be complied with in good faith. In a sale, the seller undertakes to transfer ownership and deliver the thing sold, while the buyer undertakes to pay the price. (Lawphil)

The Basic Rule: Full Payment Usually Requires Complete Delivery

The Civil Code is very practical on this point: payment does not mean only handing over money. “Payment” also means performance of the obligation. A debt is not considered paid unless the thing or service due has been completely delivered or rendered. The same provision warns buyers to be careful because if they knowingly accept incomplete or irregular performance without protest, the obligation may be deemed fully complied with. (Lawphil)

For sales of goods, Article 1522 of the Civil Code is especially important. If the seller delivers a quantity less than what was contracted, the buyer may reject the goods. But if the buyer accepts or keeps the goods knowing the seller will not fully perform, the buyer must pay for the goods actually delivered at the contract rate. If the buyer used or disposed of the goods before knowing the seller would not complete the delivery, the buyer is liable only for the fair value of what was received. (Lawphil)

In ordinary language: the supplier is not automatically entitled to full payment for undelivered items, but you also should not assume you can keep and use the delivered items for free. The cleanest position is usually to pay, offer to pay, or set aside the undisputed value of what was actually delivered, while clearly disputing the balance.

Your Key Rights Under Philippine Law

You may refuse an incomplete delivery in proper cases

If the contract was for a specific complete order and partial delivery defeats the purpose of the purchase, you may reject the incomplete delivery. This is stronger when:

The goods are indivisible or useless unless complete.
The contract states “complete delivery only” or “no partial delivery.”
The missing items are essential to operation or resale.
The delivery date was a controlling reason for the order.
The supplier already says it will not deliver the balance.

Civil Code Article 1248 also says that, unless there is an express stipulation, a creditor cannot be compelled to partially receive the prestations in which the obligation consists. In a supply transaction, the buyer is the creditor as to delivery of the goods. (Lawphil)

You may accept the delivered items but dispute the balance

This is often the practical choice when the delivered goods are useful and urgently needed. For example, a sari-sari store, restaurant, contractor, or online reseller may not want to reject everything if 80% of the order arrived.

If you accept the partial delivery, do it carefully:

State in writing that acceptance is subject to shortage or quantity verification.
Identify exactly what was missing.
State that payment, if any, is only for the delivered items.
Demand completion, replacement, refund, or credit memo for the undelivered portion.

This matters because under Article 1585, a buyer may be deemed to have accepted goods by saying so, by doing an act inconsistent with the seller’s ownership, or by retaining the goods for a reasonable time without rejecting them. But Article 1586 also provides that acceptance does not automatically remove the seller’s liability for breach, provided the buyer gives notice within a reasonable time. (Lawphil)

You may demand completion, refund, price reduction, or damages

For reciprocal obligations, Article 1191 of the Civil Code gives the injured party the choice between fulfillment and rescission, with damages in either case. “Fulfillment” means asking the supplier to complete what it promised. “Rescission” means undoing the transaction and returning what was received, when legally and practically appropriate. (Lawphil)

Article 1170 also makes a party liable for damages if, in performing its obligation, it is guilty of fraud, negligence, delay, or any act that violates the terms of the obligation. Article 1169 explains when delay begins, including after judicial or extrajudicial demand, unless demand is unnecessary under the circumstances. (Lawphil)

For sales involving warranty issues, Article 1599 allows a buyer, depending on the facts, to keep the goods and reduce or extinguish the price, keep the goods and sue for damages, refuse the goods and sue for damages, or rescind the sale and recover what was paid. (Lawphil) The Supreme Court has also applied Article 1599 in warranty disputes, emphasizing that buyers must choose and pursue the proper remedy within the applicable period. (Supreme Court E-Library)

Step-by-Step: What to Do Immediately After an Incomplete Delivery

1. Inspect the delivery before signing anything

Do not rush the receiving process, especially for bulk goods, expensive equipment, construction materials, food inventory, medical supplies, imported items, or items for resale.

Check:

Quantity per item or SKU
Box count, weight, serial numbers, and batch numbers
Packing list versus purchase order
Accessories, manuals, spare parts, cables, chargers, warranties
Visible damage, tampering, or repacking
Delivery address and consignee name
Delivery date and time

If the delivery rider or warehouse staff says “pirma muna bago bilang,” write a reservation on the receipt.

Use wording like:

Received subject to actual count and inspection. Initial count shows missing items. This receipt is not an acknowledgment of complete delivery.

If the form is digital and you cannot edit it, take screenshots, photos, and a short video while counting the items.

2. Do not sign a clean delivery receipt if the order is incomplete

A “clean” delivery receipt is one that simply says the goods were received in good order, complete, or satisfactory condition.

If you must sign, add handwritten notes such as:

“Short delivery: only 80 of 100 units received.”
“Missing: 10 boxes Model X, 5 boxes Model Y.”
“Subject to warehouse count.”
“Received under protest.”
“Partial delivery only.”
“Not acceptance of full invoice.”

Ask the delivery representative to countersign your notation. If they refuse, take a photo of the notation and record the name, vehicle plate, date, and time.

3. Segregate the delivered goods

Do not immediately mix the delivered items with old stock if the shortage may later be disputed. Keep them separate long enough to document:

Actual delivered quantity
Condition upon receipt
Batch or lot numbers
Whether any items were used, resold, installed, or returned

This is important because if you use or dispose of the goods, the dispute may shift from “I reject the delivery” to “I accepted part of it and dispute only the balance.”

4. Send a written notice of shortage immediately

Do not rely only on calls. Send a written notice by email, SMS, Viber, Messenger, platform chat, registered mail, or courier. The point is to create a timestamped record.

Your notice should include:

Purchase order, invoice, or transaction number
Date and time of delivery
Expected quantity and actual quantity received
Photos, videos, delivery receipt, and inventory count
Your requested remedy
A clear deadline for action
A reservation of rights

Example:

We refer to PO No. 2026-014 for 100 units of Item A. On 3 July 2026, only 80 units were delivered to our warehouse. We are documenting this as a short delivery of 20 units. We do not accept the invoice as fully payable. Please deliver the missing 20 units within five calendar days or issue a credit memo/refund for the undelivered portion. Any payment made or offered for the 80 units shall not be treated as acceptance of complete delivery.

5. Pay only the undisputed amount, or clearly mark payment as under protest

If the contract has a clear unit price, compute the value of the delivered items and separate it from the disputed amount.

For example:

Order	Contract Price	Delivered	Undelivered	Practical Position
100 units at ₱1,000 each	₱100,000	80 units	20 units	₱80,000 undisputed, ₱20,000 disputed
10 boxes as one complete kit	₱50,000	8 boxes	2 boxes	May reject if incomplete kit is unusable
Equipment + accessories	₱200,000	Main equipment only	Accessories missing	Demand completion or price reduction

If you pay anything, mark it clearly:

“Partial payment for delivered items only”
“Payment under protest”
“Without prejudice to claim for missing items”
“Not waiver of shortage claim”

This avoids the common supplier argument that payment means you accepted the entire invoice as complete.

6. Send a formal demand letter if the supplier ignores you

A demand letter is useful because it puts the supplier in formal default and helps prove delay or breach. Under Article 1169, delay generally begins from judicial or extrajudicial demand, unless the law or contract provides otherwise or demand would be useless. (Lawphil)

A strong demand letter should state:

The contract or purchase order terms
What was actually delivered
What remains missing
The amount disputed
The legal basis for withholding full payment
The remedy demanded: completion, refund, replacement, credit memo, rescission, or damages
A deadline, usually 3 to 7 calendar days for simple shortages
A warning that you will file the proper complaint or case if unresolved

For high-value transactions, attach copies, not originals, of the supporting documents.

Where to File a Complaint in the Philippines

The correct forum depends on the type of transaction.

Situation	Possible Forum	Notes
Consumer bought goods from a store, supplier, or online seller	DTI	Best for consumer transactions involving refund, replacement, deceptive sales acts, unfair practices, or warranty issues
Buyer and supplier are both businesses	Court, arbitration if agreed, or negotiated settlement	DTI may decline purely commercial B2B disputes not covered as consumer complaints
Natural persons in the same city/municipality	Barangay conciliation first, if covered	Often required before court filing
Supplier is a corporation, partnership, or juridical entity	Usually not barangay conciliation	Barangay conciliation covers individuals, not juridical entities
Money claim not exceeding ₱1,000,000	Small claims court	For purely monetary claims such as refund, unpaid price, or reimbursement
Claim involves injunction, specific performance, rescission, damages beyond small claims, or complex issues	Regular civil action	May take longer and require fuller pleadings and evidence

Filing with DTI for Consumer Transactions

If you are a consumer dealing with a Philippine seller or supplier, the Department of Trade and Industry may be the most practical first forum. DTI states that complaints may be filed through its consumer portal, email, or in person, and its complaint guidance requires details such as the parties’ names, narration of facts, demand, proof of transaction, and government-issued ID. (Fair Trade Enforcement Bureau)

For online sellers, DTI’s e-commerce FAQ says complaints may be sent to the Fair Trade Enforcement Bureau and that DTI accommodates complaints for both online and offline businesses. (DTI ECommerce)

DTI’s mediation and adjudication rules apply to consumer complaints involving the Consumer Act of the Philippines and other fair trade laws. An initial complaint must include the parties’ details, a brief narration of facts, the relief requested, and evidence supporting the claim. (ASEAN Consumer)

DTI mediation is mandatory in covered consumer complaints and is a condition before a formal complaint for adjudication. Under the same rules, a Notice of Mediation may be issued within three working days, depending on the situation. (ASEAN Consumer)

Barangay Conciliation: When It Is Required

Barangay conciliation under the Katarungang Pambarangay system can be required before filing in court or certain government offices. The Supreme Court has issued guidelines stating that prior barangay conciliation is generally a precondition, subject to exceptions. (Lawphil)

Important exceptions include:

One party is the government.
The dispute involves a public officer’s official functions.
The parties reside in different cities or municipalities, unless adjoining barangays and they agree to submit.
The case involves corporations, partnerships, or juridical entities.
Urgent legal action is necessary.
The offense involved is beyond the barangay’s authority.

The Supreme Court has also recognized that non-compliance with required barangay conciliation can affect the sufficiency of the plaintiff’s cause of action and cause the case to be treated as premature. (Supreme Court E-Library)

In supplier disputes, barangay conciliation is usually relevant only when both parties are individuals, such as a buyer and a sole proprietor who actually reside in the same city or municipality. It is usually not the route if the supplier is a corporation.

Small Claims Court for Refunds or Unpaid Amounts

If the dispute is purely about money — for example, refund of the undelivered portion, reimbursement, or collection of the price of delivered goods — small claims may be available if the amount does not exceed ₱1,000,000, excluding interest and costs. The Supreme Court’s Rules on Expedited Procedures increased the small claims threshold to ₱1,000,000 and include money claims arising from the sale of personal property. (Supreme Court of the Philippines)

Small claims are designed to be fast and simplified. Lawyers are generally not allowed to appear for parties at the hearing unless the lawyer is the plaintiff or defendant. Parties must personally appear, although a representative may appear for a valid cause with proper authority. (Supreme Court of the Philippines)

The court may render judgment within 24 hours from the termination of the hearing, and the decision is final, executory, and unappealable. (Supreme Court of the Philippines)

Evidence You Should Prepare

Evidence	Why It Matters
Purchase order, quotation, contract, or chat confirmation	Proves what quantity and terms were agreed
Invoice and official receipt	Shows price, billing, taxes, and payment status
Delivery receipt or waybill	Shows what the supplier claims was delivered
Packing list	Helps compare expected versus actual items
Photos and videos during unpacking	Strong proof of shortage or tampering
Warehouse receiving report	Useful for business buyers with inventory controls
CCTV footage	Helps prove actual delivery count
Screenshots of messages	Shows admissions, excuses, or promises to complete delivery
Payment proof	Shows whether payment was full, partial, or withheld
Demand letter and proof of sending	Shows notice, deadline, and supplier’s default
Credit memo or replacement agreement	Documents any settlement
Affidavits of receiving staff or witnesses	Useful if the supplier disputes the facts

For digital evidence, keep the original files where possible. Screenshots are helpful, but original emails, platform messages, metadata, and exported chat histories are stronger.

Special Issues for Foreigners and Filipinos Abroad

If you are outside the Philippines but dealing with a Philippine supplier, you can still preserve your claim. The main challenge is representation and documents.

Practical points:

Keep all transaction records in English or Filipino where possible.
If someone in the Philippines will appear for you, prepare a Special Power of Attorney.
If the SPA or affidavit is signed abroad, it may need consular notarization or apostille, depending on the country where it is signed.
The Philippines became a party to the Apostille Convention on 14 May 2019, so apostille may replace consular legalization for public documents from member countries. (Apostille.gov.ph)
If the supplier contract has a governing law, venue, or arbitration clause, read it before filing anywhere.
If the supplier is overseas but has a Philippine branch, agent, platform store, or registered business, jurisdiction and service of notices may become more manageable.

Foreigners doing business in the Philippines should also check whether the transaction is personal, commercial, import-related, or part of a regulated industry. A simple online consumer complaint is different from a cross-border distributorship, construction supply contract, or import shipment dispute.

Common Mistakes That Weaken Your Case

Signing “received complete and in good condition”

This is the most common problem. A clean receipt is not always fatal, but it creates an avoidable evidentiary issue. Always add a written reservation if the count is not complete.

Waiting too long to complain

A delay can make the supplier argue that you accepted the goods. Article 1586 protects buyers who accepted goods but still gave notice of the breach within a reasonable time. Do not wait weeks before reporting a shortage that could have been discovered on delivery. (Lawphil)

Using all the goods while refusing to pay anything

If you keep and use the delivered portion, the supplier may have a valid claim for the value of those items. Your dispute should be focused on the undelivered balance, damages, or price reduction.

Making only verbal complaints

Phone calls are easy to deny. After every call, send a written recap: “As discussed today at 2:00 p.m., you confirmed that 20 units remain undelivered and promised completion by Friday.”

Filing in the wrong forum

A consumer complaint, barangay case, small claim, regular civil case, and criminal complaint are different routes. Filing in the wrong place wastes time and may give the supplier more leverage.

Threatening estafa without facts showing fraud

Not every incomplete delivery is a crime. Estafa under Article 315 of the Revised Penal Code generally requires deceit, false pretenses, or fraudulent means that induced the victim to part with money or property. Philippine jurisprudence emphasizes that the false pretense must exist before or at the same time as the fraud, not merely after a contract later goes bad. (Supreme Court E-Library)

A supplier who honestly had logistics problems may be civilly liable but not criminally liable. A supplier who never intended to deliver, used a fictitious business, presented fake inventory, or repeatedly used the same scheme may raise different issues.

Frequently Asked Questions

Can I refuse to pay the full invoice if the supplier delivered incomplete items?

Yes, if the invoice includes undelivered items, you can dispute the unpaid balance. The safer approach is to document the shortage immediately and offer or make payment only for the delivered items if their value is clear.

Can the supplier charge penalties or interest even though delivery was incomplete?

Only if the contract allows it and the supplier can show that you were the one in default. If the supplier failed to deliver first, its claim for penalties may be weak because reciprocal obligations require proper performance by both sides.

What if I already signed the delivery receipt?

You can still dispute the delivery, but you need stronger evidence. Send a written notice immediately, attach photos, CCTV, inventory reports, witness statements, and any proof that the receipt was signed before full counting or subject to later inspection.

What if the supplier says partial delivery is normal in their industry?

Trade usage, course of dealing, and special agreement can matter. Article 1522 itself recognizes that rules on quantity delivery may be affected by usage of trade, special agreement, or course of dealing. If previous orders were always delivered in batches and paid per batch, that may affect the analysis. (Lawphil)

Can I reject the whole delivery if only some items are missing?

Sometimes. Rejection is stronger if the missing items make the delivery unusable, the contract required complete delivery, or the goods are indivisible. If the delivered items are separable and useful, the more practical remedy may be acceptance of the delivered portion with a claim for completion, refund, or price reduction.

Should I file with DTI or in court?

File with DTI if you are a consumer and the complaint involves a seller’s unfair, deceptive, warranty, refund, replacement, or delivery-related issue. Consider court if it is a business-to-business dispute, a pure money claim, a high-value commercial contract, or a case requiring damages, rescission, or other relief beyond DTI’s practical remedies.

Can a business file a small claims case against a supplier?

Yes, if the claim is a covered money claim not exceeding ₱1,000,000, excluding interest and costs. Juridical entities must be properly represented, and small claims hearings generally do not allow lawyers to appear for the parties. (Supreme Court of the Philippines)

What if the supplier is a corporation and we are in the same barangay?

Barangay conciliation generally does not cover complaints by or against corporations, partnerships, or other juridical entities because only individuals are parties to barangay conciliation proceedings. (Lawphil)

Can I post about the supplier online?

Be careful. You may describe your experience truthfully, but accusations of fraud, scam, or estafa can trigger defamation or cyberlibel issues if stated recklessly. For legal leverage, a documented demand letter or proper complaint is usually safer than an emotional public post.

What is the best first message to send the supplier?

Use a calm, specific message:

We received only ___ out of ___ items under Invoice/PO No. ___. We are documenting this as an incomplete delivery. Please deliver the missing items or issue a credit memo/refund by ___. We dispute any demand for full payment until the order is completed or adjusted.

Key Takeaways

A supplier who delivers incomplete orders is generally not entitled to full payment for undelivered items unless the contract clearly provides otherwise.
Inspect the delivery before signing; if you must sign, write “partial delivery,” “subject to count,” or “received under protest.”
Send written notice immediately. Delay can make it look like you accepted the delivery without objection.
If you keep and use the delivered goods, be ready to pay the fair or contract value of what was actually received.
For consumer transactions, DTI mediation may be a practical first step.
For money claims up to ₱1,000,000, small claims court may be available.
Barangay conciliation may be required for disputes between individuals in the same city or municipality, but not usually for corporations or partnerships.
Estafa is not automatic. Incomplete delivery is usually civil unless there is evidence of deceit or fraudulent intent from the start.
