A supplier may ask for full payment after delivering an incomplete order, but that does not automatically mean the buyer is legally required to pay the entire invoice. Under Philippine law, the answer depends on the purchase order, contract, delivery terms, extent of the shortage, whether the buyer accepted the delivery without protest, and whether the missing items can still be supplied. In many cases, the buyer may reject the incomplete delivery, require completion, pay only for the goods properly delivered, reduce the price, claim damages, or cancel the contract if the shortage is substantial.

Is Full Payment Required When the Order Is Incomplete?

The starting point is the parties’ agreement.

Article 1159 of the Civil Code provides that contractual obligations have the force of law between the parties and must be performed in good faith. A purchase order, quotation accepted by the buyer, supply agreement, invoice, delivery schedule, email exchange, or even the parties’ established course of dealing may form part of the contract. (Lawphil)

A supplier’s right to collect usually depends on the agreed payment trigger:

Payment term	Likely effect of incomplete delivery
“Full payment upon complete delivery and acceptance”	Full payment is generally not yet due until the order is completed and accepted.
“Pay per item or per batch delivered”	The supplier may collect for conforming items or completed batches.
“50% down payment, balance upon delivery”	The buyer may dispute whether “delivery” means any delivery or complete delivery. The whole contract must be read together.
“100% payment before shipment”	The buyer may have to pay first under the contract but may later demand completion, replacement, refund, or damages.
Stated installment deliveries with separate billing	A defective installment may affect only that installment unless the breach is serious enough to defeat the entire contract.

Article 1458 of the Civil Code defines a sale as a contract in which the seller undertakes to transfer ownership and deliver a determinate thing, while the buyer undertakes to pay a certain price. Delivery and payment are therefore reciprocal obligations: each party’s performance is normally given in exchange for the other’s performance. (Lawphil)

What Philippine Law Says About Incomplete Delivery

The supplier must generally perform the obligation completely

Under Articles 1232 and 1233 of the Civil Code, “payment” includes the performance of an obligation, and an obligation is not considered performed unless the thing or service due has been completely delivered or rendered.

If a supplier agreed to deliver 500 pieces but delivered only 350, the supplier has not ordinarily completed its obligation merely because some goods reached the buyer. (Lawphil)

Article 1248 also states that, unless the parties expressly agreed otherwise, a creditor cannot be compelled to accept partial performance. Applied to a supply contract, a buyer who ordered one complete quantity or package is not normally required to accept an incomplete delivery as final performance. (Lawphil)

A buyer may reject a short delivery

Article 1522 directly addresses delivery of fewer goods than the quantity contracted for. It provides that when a seller delivers less than the agreed quantity, the buyer may reject the goods.

If the buyer accepts or keeps the delivered goods while knowing that the supplier will not complete the order, the buyer must generally pay for the quantity accepted at the contract rate. The supplier does not automatically become entitled to the price of the undelivered goods. (Lawphil)

For example, suppose a restaurant orders 100 chairs at ₱2,000 each, but the supplier delivers only 80 and states that the remaining 20 will never be delivered. The restaurant may generally:

Reject the short delivery, subject to the contract and circumstances; or
Keep the 80 chairs and pay the contract price for those 80, while pursuing any provable losses caused by the shortage.

The result may differ if the chairs were sold as one indivisible package, such as a coordinated event setup that has no practical value unless complete.

Buyers are not normally required to accept installment deliveries

Article 1583 states that, unless otherwise agreed, a buyer is not required to accept delivery by installments.

Where the contract expressly provides for separate deliveries and separate payments, a defect in one installment does not always cancel the entire agreement. The key question is whether the defective installment is severable or whether it is so important that it defeats the purpose of the whole contract. (Lawphil)

A shortage of five ordinary office pens from an order of 5,000 may be minor. A missing control unit from a complete manufacturing system may be substantial even if the control unit represents only a small percentage of the total price.

Can the Supplier Claim Substantial Performance?

Possibly.

Article 1234 allows a party that has substantially performed an obligation in good faith to recover as though there had been complete performance, but the amount must be reduced by the damages suffered by the other party.

This means a supplier that honestly completed almost all of an order, with only a minor and readily correctable deficiency, may still have a valid claim for most or even nearly all of the price. However, the buyer may claim an appropriate deduction for the shortage, replacement cost, delay, or other proven loss. (Lawphil)

Substantial performance is not based on percentage alone. Relevant considerations include:

Whether the missing items are essential;
Whether the goods can be used for their intended purpose;
Whether the supplier acted in good faith;
Whether completion remains possible;
Whether the delay caused operational or financial loss;
Whether the buyer received substantially the benefit promised; and
Whether the contract treats complete delivery as a strict condition for payment.

A supplier that deliberately withheld expensive items, substituted inferior products, or repeatedly promised completion without intending to deliver will have a weaker claim of good-faith substantial performance.

Why the Buyer Must Object Promptly

Silence can seriously weaken the buyer’s position.

Article 1235 provides that when a party accepts incomplete or irregular performance while knowing of the problem and expresses no protest or objection, the obligation may be treated as fully complied with. (Lawphil)

Articles 1584 to 1586 also give the buyer a reasonable opportunity to examine the goods. Acceptance may be inferred if the buyer expressly accepts them, acts in a manner inconsistent with the seller’s ownership, or keeps them for an unreasonable period without communicating rejection. Even after acceptance, remedies may remain available, but the buyer must notify the seller of the breach within a reasonable time. (Lawphil)

The buyer should therefore avoid signing a delivery receipt stating “complete and in good order” when the quantity has not been counted.

A safer notation is:

Received subject to complete inspection and verification. Shortage noted: 25 units missing. Acceptance is without waiver of the buyer’s rights.

If the delivery receipt was already signed, the buyer should send a written discrepancy notice immediately after discovering the shortage.

What Remedies Can the Buyer Use?

The appropriate remedy depends on the seriousness of the incomplete delivery.

Require the supplier to complete the order

The buyer may demand fulfillment or specific performance. This means requiring the supplier to deliver the missing goods in accordance with the contract.

Article 1598 permits a court, in appropriate cases involving specific or ascertained goods, to order the seller to perform the delivery obligation instead of merely paying damages. (Lawphil)

This remedy is practical when:

The missing goods are still available;
The goods are unique or difficult to obtain elsewhere;
Completion can occur within an acceptable period; or
Cancellation would cause greater disruption than delayed completion.

Pay only for the quantity properly accepted

Where the price is calculated per unit and the buyer keeps only the quantity delivered, Article 1522 generally supports payment at the contract rate for the accepted quantity.

The buyer should prepare a written computation showing:

Quantity ordered;
Quantity delivered and accepted;
Quantity missing or rejected;
Contract price per unit;
Amount already paid;
Undisputed balance; and
Disputed amount.

Paying or formally offering to pay the undisputed amount can show good faith. It also reduces the risk that the supplier will portray the buyer as refusing all payment despite having used the delivered goods.

Reduce or offset the price

Article 1599 allows a buyer, in cases involving breach of warranty, to retain the goods and raise the breach as a basis for reducing or extinguishing the price. The buyer may also keep the goods and claim damages. (Lawphil)

The deduction should be based on evidence, not guesswork. Relevant amounts may include:

Contract value of missing goods;
Reasonable cost of obtaining replacements;
Additional shipping or installation expenses;
Documented storage or handling costs;
Penalties owed to the buyer’s customer, if foreseeable and properly proven; and
Other direct losses caused by the breach.

Speculative lost profits are harder to recover. Courts usually require clear evidence that the loss was foreseeable, directly caused by the breach, and capable of reasonable computation.

Cancel or resolve the contract

Article 1191 allows the injured party in a reciprocal obligation to choose between fulfillment and resolution of the contract, with damages in either case. Resolution is commonly called “rescission” in Article 1191, although it is legally distinct from rescission based on economic prejudice under other Civil Code provisions. (Lawphil)

Cancellation is generally justified only by a substantial or fundamental breach, not a slight or casual deficiency. The Supreme Court explained in Golden Valley Exploration, Inc. v. Pinkian Mining Company, G.R. No. 190080, June 11, 2014, that resolution ordinarily requires a breach serious enough to defeat the object of the parties’ agreement. (Lawphil)

A buyer should be cautious about declaring a contract cancelled without checking whether the agreement contains an enforceable extrajudicial cancellation clause. In the absence of such a provision or clear acceptance by the supplier, the cancellation may remain subject to court review.

Step-by-Step Guide for Buyers

Inspect and count the delivery immediately. Compare the goods against the purchase order, approved quotation, packing list, delivery receipt, and invoice.
Photograph or record the opening of the shipment. For sealed boxes, palletized deliveries, or online purchases, a continuous unpacking video can help prove that the shortage existed upon receipt.
Write the shortage on the delivery receipt. Do not rely only on a verbal promise from the driver or warehouse staff.
Send a written discrepancy notice. Email the supplier and send a message through the platform or official business channel. State the exact quantity and items missing.
Review the payment clause. Determine whether payment becomes due upon shipment, partial delivery, complete delivery, inspection, installation, or formal acceptance.
State the remedy you are choosing. Ask for completion, replacement, proportional billing, price reduction, refund, or cancellation. Avoid making inconsistent demands.
Offer the undisputed amount where appropriate. Clearly state that payment of the undisputed portion does not waive claims concerning the shortage.
Give a reasonable deadline. Five to ten business days is often practical for an ordinary commercial demand, although urgent or perishable transactions may require a shorter period.
Preserve proof of delivery of the demand. Use registered mail, reputable courier, email with delivery records, or the platform’s complaint system. Proof of receipt is usually more important than notarization.
Escalate to the proper forum if the supplier does not cure the breach.

A written extrajudicial demand is especially useful because Article 1169 generally places an obligor in delay after judicial or extrajudicial demand. A written demand may also interrupt prescription under Article 1155. (Lawphil)

What the Written Demand Should Contain

A useful demand letter should identify:

The buyer and supplier;
Purchase order or contract number;
Date and place of delivery;
Goods and quantity ordered;
Goods and quantity actually received;
Amount paid and amount being withheld;
Photographs, reports, or delivery records supporting the shortage;
Contract provisions violated;
The specific remedy demanded;
Deadline for compliance;
Instructions for collection or return of rejected goods; and
A reservation of the buyer’s rights to damages, refund, and further proceedings.

Notarization is not generally required for an ordinary demand letter. It may help establish the date and authenticity of the document, but it does not replace proof that the supplier actually received it.

Consumer Purchases, Business Orders, and Online Transactions

Consumer transactions

For goods purchased mainly for personal, family, or household use, the Consumer Act of the Philippines, Republic Act No. 7394, may apply in addition to the Civil Code. The law prohibits deceptive, unfair, and unconscionable sales practices and authorizes the Department of Trade and Industry to handle covered consumer complaints. (Lawphil)

DTI also recognizes repair, replacement, and refund remedies for defective or nonconforming consumer goods. A seller cannot defeat statutory consumer remedies merely by displaying a blanket “No Return, No Exchange” notice. (Fair Trade Enforcement Bureau)

Business-to-business supply contracts

A company purchasing raw materials, inventory, industrial equipment, or supplies for business operations is not automatically treated as an ordinary consumer. A dispute between two businesses is usually resolved through:

Negotiation;
Contractual mediation or arbitration;
A civil action for collection, damages, fulfillment, or resolution; or
Small claims proceedings if the relief sought is purely payment or reimbursement of money and falls within the monetary limit.

The arbitration, governing-law, venue, inspection, and acceptance clauses in the supply agreement should be reviewed before filing a complaint.

Online orders

Republic Act No. 11967, the Internet Transactions Act of 2023, gives online consumers the right to pursue repair, replacement, refund, or other remedies when goods fail to conform to the contract or the online merchant incurs liability arising from the transaction. When replacement or refund is chosen, the merchant is generally entitled to the return of the original goods without cost to the consumer. (Supreme Court E-Library)

For marketplace purchases, preserve:

Screenshots of the product listing;
Order confirmation;
Seller chat;
Platform dispute records;
Payment confirmation;
Courier tracking;
Unboxing video; and
Photographs of package labels and contents.

File the platform dispute before its internal deadline. A platform’s short return window does not necessarily erase statutory rights, but missing the platform deadline may remove the fastest practical method of obtaining a refund.

Where Can the Buyer File a Complaint?

Forum	When it may apply	Important points
Supplier’s internal complaints process	Most transactions	Usually the fastest first step. Keep everything in writing.
E-commerce platform dispute system	Marketplace purchase	File promptly and upload complete evidence.
DTI mediation and adjudication	Covered consumer transaction	Complaints may begin with mediation and proceed to adjudication if no settlement is reached.
Barangay conciliation	Certain disputes between individuals residing in the same city or municipality	Usually not applicable when a corporation, partnership, or other juridical entity is a party.
Small claims court	Pure money claim not exceeding ₱1,000,000, excluding interest and costs	Available for money owed or reimbursement arising from a sale of personal property.
Regular civil action	Claims seeking delivery, cancellation, injunction, substantial damages, or relief outside small claims	Court and procedure depend on the nature and amount of the claim.
Arbitration	Contract contains a valid arbitration agreement	A court case may be dismissed or suspended in favor of arbitration.

Consumers in Metro Manila may submit a complaint through the DTI Consumer CARe System or through the DTI Fair Trade Enforcement Bureau’s designated complaint channels. Mediation ordinarily comes first; formal adjudication may follow if settlement efforts fail. (Fair Trade Enforcement Bureau)

Barangay conciliation is generally a precondition only in covered disputes between natural persons. Complaints by or against corporations, partnerships, and other juridical entities are excluded. (Lawphil)

Small Claims Cases for Incomplete Orders

Under the Supreme Court’s Rules on Expedited Procedures in the First Level Courts, a small claims action may be filed when:

The claim does not exceed ₱1,000,000, excluding interest and costs;
The relief is solely the payment or reimbursement of money; and
The claim arises from a covered transaction, including the sale of personal property.

A claim seeking an order compelling the supplier to deliver the missing goods is not a pure money claim and normally falls outside small claims. A claim for refund, reimbursement, or a definite monetary loss may qualify. (Supreme Court of the Philippines)

The claimant generally files Form 1-SCC together with the contract or purchase order, affidavits, demand letter, proof of receipt, and other supporting evidence. Evidence should be attached at filing because later evidence may be excluded without good cause. Lawyers cannot appear for parties at the small claims hearing unless the lawyer is personally a party. (Supreme Court of the Philippines)

The rules contemplate a hearing within 30 calendar days from filing, or within 60 calendar days when a defendant resides or does business outside the judicial region. The court is directed to render judgment within 24 hours after termination of the hearing, although actual completion may be delayed by service of summons, docket congestion, address problems, or requests to submit original documents. (Supreme Court of the Philippines)

Documents to Prepare

Document	Why it matters
Signed contract or supply agreement	Shows delivery, payment, inspection, and dispute-resolution terms.
Purchase order and accepted quotation	Proves the exact goods, quantities, specifications, and price.
Invoice and official receipt	Shows the amount demanded and amounts already paid.
Delivery receipt and packing list	Shows what the supplier claims was delivered.
Inventory or discrepancy report	Identifies the shortage and who verified it.
Photos and unboxing video	Helps prove the condition and contents upon arrival.
Emails, texts, and platform messages	Shows admissions, promises to complete, and notices of breach.
Demand letter and proof of receipt	Establishes formal notice and the requested remedy.
Replacement quotations and receipts	Supports the amount of direct damages.
Board resolution or secretary’s certificate	May be required when a corporation authorizes a representative.

Special Considerations for Buyers Outside the Philippines

A Filipino or foreign buyer based abroad can still send a written demand and preserve evidence electronically.

If a Philippine court appearance or settlement will be handled by a local representative, the buyer may need a Special Power of Attorney. A document notarized abroad will commonly need an apostille if issued in a country covered by the Apostille Convention. Documents from non-participating countries may require authentication through the appropriate Philippine diplomatic or consular post.

A foreign corporation bringing a Philippine court action should also check its legal capacity to sue, authority of its representative, and whether it is considered to be doing business in the Philippines. An isolated transaction may be treated differently from continuous commercial activity.

Common Mistakes to Avoid

Signing “complete and in good order” before counting the goods;
Waiting weeks or months before reporting an obvious shortage;
Using or reselling all delivered goods while claiming total rejection;
Withholding the entire price when only a small, separable amount is disputed;
Deducting speculative losses without receipts or calculations;
Sending a demand only to a sales agent with no proof it reached the supplier;
Ignoring an arbitration or dispute-resolution clause;
Missing a marketplace’s return or dispute deadline;
Asking simultaneously for completion, total cancellation, and unrestricted use of the goods;
Discarding packaging, labels, seals, or damaged items before documentation;
Assuming that a demand for full payment is the same as a court ruling that full payment is due.

Frequently Asked Questions

Can I refuse to pay the entire invoice if some items are missing?

Possibly, especially when complete delivery is a condition for payment or the missing items make the entire order unusable. However, withholding the entire amount may be risky when the delivered portion is usable, accepted, and separately measurable. Consider paying or offering the undisputed amount while expressly reserving your rights.

Can the supplier charge interest on the unpaid balance?

Only if the amount is legally due and the contract or law supports interest. Contractual interest may apply if validly agreed. In the absence of an agreed rate, Article 2209 recognizes legal interest of 6% per year for delayed payment of a sum of money, subject to the court’s determination of when the obligation became due and the debtor went into delay. (Lawphil)

What if I signed the delivery receipt without noticing the shortage?

Send a written notice immediately after discovery. Explain how and when the shortage was discovered and attach inventory records, photographs, CCTV footage, or an unboxing video. The signature is evidence of receipt, but its effect depends on the wording of the document and the surrounding circumstances.

Can the supplier sue me for nonpayment?

Yes. The supplier may file a collection case or use arbitration if the contract requires it. You may raise incomplete delivery, lack of maturity of the payment obligation, price reduction, damages, breach of warranty, or other appropriate defenses and counterclaims.

Can I buy the missing items elsewhere and charge the difference to the supplier?

Potentially, if the supplier was given a reasonable opportunity to cure, failed to do so, and the replacement purchase was reasonable and necessary. Keep quotations, receipts, correspondence, and proof that the replacement was caused by the supplier’s breach.

Does accepting part of the order mean I waived the shortage?

Not automatically. Acceptance does not always eliminate remedies, especially when the buyer promptly notifies the supplier. Waiver becomes more likely when the buyer knew of the shortage, accepted the performance as complete, and made no protest.

Can I cancel the whole contract because of one missing item?

Only when the missing item or resulting breach is substantial enough to defeat the contract’s purpose, or when the agreement expressly permits cancellation. A minor, separable shortage may justify completion, a price reduction, or damages rather than total cancellation.

Is a police report necessary?

Usually not. Incomplete delivery is normally a civil or consumer dispute. A police or criminal complaint may become relevant only when there is evidence of fraud or another criminal act, not merely because the supplier failed to complete a contractual obligation.

How long should I give the supplier to complete the order?

Use the period stated in the contract. If there is none, give a reasonable period based on the nature of the goods, availability, urgency, and previous promises. For ordinary goods, five to ten business days is often a practical demand period, but customized, imported, or perishable goods may require a different approach.

Can attorney’s fees be recovered?

Attorney’s fees are not automatically awarded. Article 2208 allows them only in specified circumstances, such as when a party’s bad-faith refusal to satisfy a plainly valid claim forces the other party to litigate. Any award must be reasonable and supported by the court’s findings. (Lawphil)

Key Takeaways

A supplier may demand full payment, but the demand is enforceable only if the contract and actual performance make the full price due.
Philippine law generally requires complete performance unless partial or installment delivery was agreed.
A buyer may reject a short delivery or keep the delivered quantity and pay for what was properly accepted.
Substantial performance in good faith may allow the supplier to recover the price, less the buyer’s proven damages.
Buyers should inspect immediately, note shortages on the delivery receipt, and send a prompt written objection.
Pay or tender the undisputed amount when appropriate instead of withholding everything without explanation.
Consumers may use the DTI process, while business supply disputes usually proceed through negotiation, arbitration, small claims, or a regular civil action.
Small claims may be used for pure money claims up to ₱1,000,000, but not ordinarily for an order compelling delivery of missing goods.
