My Customer Won't Pay an Invoice: Legal Options for NY Small Businesses

By Eugene Bondar, Esq.

An unpaid invoice is one of the most common, and most frustrating, problems a small business faces. The work is done, the bill is out, and the other side has gone quiet. The good news is that you usually have more options than “write it off” or “sue,” and the right one depends less on how angry you are than on how much is owed, why they’re not paying, and whether you ever want to do business with them again.

First, figure out why they aren’t paying

Non-payment falls into a few buckets, and each points to a different response. Sometimes it’s an oversight: the invoice went to the wrong contact or got buried. Sometimes it’s a cash-flow problem and the customer fully intends to pay, just not yet. Sometimes there’s a genuine dispute about the work or the amount. And sometimes the customer simply has no intention of paying and is betting you won’t chase it. The first three call for communication; the last one calls for leverage. A quick, documented conversation usually tells you which situation you’re in.

Build the paper trail before you escalate

Whatever you do next, your position is only as strong as your documentation. Pull together the contract or signed proposal, the invoice, proof the work was delivered or accepted, and any emails or texts where the customer acknowledged the bill or the scope. If your contract provides for interest on late payments, attorneys’ fees, or a specific cure period, find those terms now. They change both your leverage and what you can ultimately recover. Strong records turn a “he-said, she-said” into a straightforward claim.

Send a clear final notice

Before involving a lawyer, a direct written notice often works. It should state the amount owed, reference the invoice and contract, set a firm deadline, and say plainly what happens if the deadline passes. Keep it factual and unemotional; anything you write can be quoted back to you later. Many slow-paying customers respond to a notice that reads like the last step before escalation rather than another routine reminder.

When a demand letter from counsel makes sense

If the final notice goes unanswered and the amount justifies it, a demand letter on a law firm’s letterhead changes the tone of the conversation. It signals that escalation is one decision away, not one hiring process away, and it gets the legal framing right the first time. For clear obligations against a customer who can pay, this step resolves a large share of disputes without anyone filing anything.

The litigation options: sized to the claim

If the debt still isn’t paid, New York gives you forums scaled to the amount. The small claims and commercial claims parts handle modest sums cheaply. In the New York City Civil Court a small claim is “any cause of action for money only not in excess of ten thousand dollars exclusive of interest and costs” (N.Y. City Civ. Ct. Act § 1801). In city courts and district courts outside the City the cap is “five thousand dollars exclusive of interest and costs” (Uniform City Ct. Act § 1801; Uniform Dist. Ct. Act § 1801), and in town and village courts it is “three thousand dollars exclusive of interest and costs” (Uniform Justice Ct. Act § 1801). One point that trips up business owners: a business entity generally cannot be the plaintiff in small claims. Each act provides that “[n]o corporation, except a municipal corporation, public benefit corporation, school district or school district public library … shall institute an action or proceeding under this article” (N.Y. City Civ. Ct. Act § 1809(1); Uniform City Ct. Act § 1809(1); Uniform Dist. Ct. Act § 1809(1); Uniform Justice Ct. Act § 1809(1)), and the City, city court, and justice court acts extend that bar to any “partnership, or association.” In the New York City Civil Court, the city courts, and the district courts, a business claimant uses the commercial claims part instead. A commercial claim is “any cause of action for money only not in excess of the maximum amount permitted for a small claim in the small claims part of the court, exclusive of interest and costs,” where “the claimant is a corporation, partnership or association, which has its principal office in the state of New York” (N.Y. City Civ. Ct. Act § 1801-A(a); Uniform City Ct. Act § 1801-A(a); Uniform Dist. Ct. Act § 1801-A(a)). So the commercial claims part carries the same dollar cap as small claims, not a higher one. Anything above those caps, or any dispute that is more than a straightforward collection, belongs in the regular civil parts. Which court fits, and whether a lawsuit is worth it at all, turns on the size of the claim, the strength of your documentation, and, crucially, whether the customer has assets to collect against. A judgment you can’t collect is an expensive piece of paper, so collectability should be part of the decision from the start, not an afterthought. These are the kinds of matters this firm’s civil litigation practice handles.

The cheapest fix is upstream

Most invoice fights trace back to a weak agreement: no clear payment terms, no late-payment interest, no attorneys’-fee provision, no defined scope to point to when the customer claims the work was deficient. Tightening your contracts and payment terms before the next engagement won’t help with the invoice already outstanding, but it makes the next collection far easier, and often prevents the dispute entirely. Clear terms, deposits, and milestone billing do more to protect cash flow than any letter sent after the fact.

Knowing when to act

The one mistake to avoid is waiting. Memories fade, records get lost, and statutes of limitations run. For most invoice claims the clock is CPLR 213(2): “an action upon a contractual obligation or liability, express or implied” must be “commenced within six years,” except as provided in, among other things, “article 2 of the uniform commercial code.” Where the invoice is for goods rather than services, UCC 2-725(1) governs: “An action for breach of any contract for sale must be commenced within four years after the cause of action has accrued. By the original agreement the parties may reduce the period of limitation to not less than one year but may not extend it.” Acting early, while the relationship still has value to the other side and your documentation is fresh, preserves the most options and the most leverage.

If a customer owes your business money, I’ll review the file and tell you candidly which step makes sense given the amount, the paperwork, and the odds of collecting. The initial consultation is free.
