Can You Refuse to Pay Old Invoices? 5 Rules on Time Limits and Disputes

An old invoice does not expire. It becomes harder to sue on, which is a different condition, and a business that treats the two as the same usually learns the distinction from a process server rather than from its accountant.

The question of whether you can refuse to pay old invoices has two halves that owners tend to fold together. One concerns time: how long a creditor has to bring a lawsuit. The other concerns substance: whether the goods or services were worth the price, and what a buyer must do to say so. Both halves are governed by rules that punish the business that says nothing, and the invoice in the bottom drawer is precisely the kind of paper those rules were written for.

1. Age Is a Defense in Court, Not a Cancellation of the Debt

In New York the general period for a claim on a contract is six years. CPLR 213(2) gives a creditor that long to commence an action upon a contractual obligation or liability, express or implied, subject to carve-outs that include Article 2 of the Uniform Commercial Code. An invoice for consulting, repairs, cleaning, or any other service ordinarily falls on the six year side.

What the period controls is the courthouse door. A debtor sued after the period has run may raise the statute as a defense, and a court that accepts it dismisses the claim; nothing in that sequence erases the underlying obligation, and a debtor who chooses to pay an old invoice is paying something it owed. Refusal on the ground of age is a litigation position.

Where the creditor sits in another state, or the contract names another state's law, the analysis can change, and New York's borrowing rules for claims arising elsewhere are a question for counsel.

2. Goods Carry Four Years, and the Clock Starts at the Breach

A sale of goods runs on a shorter clock. Under UCC section 2-725, an action for breach of any contract for sale must be commenced within four years after the cause of action has accrued, and the cause accrues when the breach occurs, regardless of the aggrieved party's lack of knowledge of the breach. For a buyer that never paid, the breach is ordinarily the missed payment, and the seller's ignorance of its own receivables ledger does not pause anything.

The parties to a sale may shorten that period by agreement, and some supply contracts do; the terms and conditions on the back of a purchase order are worth reading for that sentence alone. An invoice that mixes goods and installation, parts and labor, can raise the question of which clock applies, and the label on the invoice does not settle it.

You get the parts, you get the labor, you get one invoice, and then you find out it might have two lives.

3. A Signed Letter Can Return the Years the Creditor Lost

General Obligations Law section 17-101 provides that an acknowledgment or promise contained in a writing signed by the party to be charged is the only competent evidence of a new or continuing contract that takes a claim out of the statute of limitations. An oral promise on a collection call does not do it. A signed letter can.

The statute states that it does not alter the effect of a part payment, and what a part payment does to the period is a separate question on which a business should take advice before it sends a check against an old balance.

4. An Invoice Kept Without Objection Becomes a Claim of Its Own

This is the rule that decides most disputes about old invoices, and it has nothing to do with the age of the paper. New York recognizes a cause of action for an account stated: an account balanced and rendered, with an assent to the balance express or implied, so that the demand is essentially the same as if a promissory note had been given for the balance.

The First Department restated the rule in TH Fashion Ltd. v Vince Holding Corp., decided September 26, 2024: a defendant's receipt and retention of invoices seeking payment for goods or services rendered, without objection within a reasonable time, gives rise to an actionable claim for account stated. The consequence for a buyer is severe, because a claim built on retention does not require the creditor to prove the underlying contract in the same way, and the buyer's complaints about quality, raised for the first time in an answer eighteen months later, arrive after the implied assent they were meant to contradict.

But the same decision marks the rule's edge. The plaintiff there had sent invoices owed by a subsidiary to the parent company, and the parent had replied that it would escalate them. The court held that soliciting the parent's help in obtaining payment did not give rise to an account stated against the parent. Receiving someone else's invoice and promising to pass it along is not assent to owing it.

The practical lesson is plain and a little uncomfortable, since it asks the buyer to do paperwork on the very invoices it least wants to think about, the ones sitting in the drawer because the job went badly and nobody could agree on what went wrong and the owner assumed, as owners tend to, that not paying was itself a sufficient statement of the objection, which under this doctrine it may not be. An objection that a court will credit is written, specific to the invoice, and sent within a reasonable time of receipt. Silence is a position too, and the law has already decided which way it points.

5. A Quality Dispute Must Be Announced Before It Can Be Used

For goods, UCC section 2-607 states the buyer's obligations in a sequence that resembles a set of locks on a canal: the buyer must pay at the contract rate for any goods accepted; acceptance precludes rejection of those goods and, where the buyer knew of a defect, generally cannot be revoked because of it; and the buyer must, within a reasonable time after it discovers or should have discovered any breach, notify the seller or be barred from any remedy. Each gate closes behind the buyer that passes through it in silence.

The Code also gives a buyer a lawful form of refusal. Section 2-717 permits a buyer, on notifying the seller of its intention to do so, to deduct all or any part of the damages resulting from a breach from any part of the price still due under the same contract. The notice is the condition. A buyer that short pays without explanation has not used section 2-717; it has paid less.

Services contracts are governed by general contract law rather than Article 2, though the same discipline serves the buyer there: a written account of what went wrong, sent while the facts are fresh, beside the invoice it concerns, filed where it can be found when the drawer is finally opened.

Where Old Balances Meet Newer Debt

A business weighing whether to refuse a supplier's old invoice is often short of cash on more than one front, and the heavier pressure frequently comes from merchant cash advances debited daily from the operating account. Those contracts carry their own terms on default, governing law, and remedies, and the rules above do not translate to them without a close reading.

Delancey Street reviews that side of the balance sheet. The company negotiates business debt, principally merchant cash advances, and is not a law firm; limitations defenses, account stated disputes, and anything else that must be argued in court belong to independently licensed counsel. The first review of the contracts is free and confidential. The six years, the four years, the reasonable time to object: each is a way of saying that commercial law rewards the party who writes things down.
