A Customer Sent a ‘Paid in Full’ Check for Less Than They Owe. Should You Cash It?

A customer who owes you $18,000 sends a check for $11,000. On the memo line, or in a short letter with it, are the words “paid in full” or “full and final settlement.” Your first instinct may be to deposit it and chase the rest later.

Slow down. In most states, cashing that check can settle the entire debt for the smaller amount, and the remaining $7,000 is gone. Here is how the rule works, when it does and does not apply, and what to do before the check goes anywhere near your bank.

Why a “paid in full” check can wipe out the rest of the debt

The legal name for this is accord and satisfaction. The customer offers a smaller amount to settle a debt they say is in dispute (the accord), and you accept it by cashing the check (the satisfaction). Once both happen, the original debt is discharged.

Most states follow Section 3-311 of the Uniform Commercial Code for payments made by check. Florida’s version, for example, is section 673.3111 of the Florida Statutes. Under that rule, the debt is generally discharged if all of these are true:

• There was a real dispute, or the amount owed was not fixed. A customer who simply does not want to pay a clear, agreed invoice cannot erase it with a memo line.
• The customer acted in good faith. For example, a customer who sends a token check on a bill that is clearly owed, hoping you won’t notice, or who prints “paid in full” on every check whether or not there is a dispute, may not meet this test.
• The check, or a letter sent with it, clearly says it is offered in full satisfaction of the claim.
• You obtained payment by cashing or depositing the check.

The catch is the first point. Customers who send these checks almost always say there was a problem with the work, the goods or the price. If that complaint is genuine, even if you think it is wrong, the dispute may be enough.

“Under protest” usually does not protect you

Many business owners believe they can cross out “paid in full,” write “cashed under protest” or “all rights reserved” on the back, and then deposit the check. In most states, that does not work. The Uniform Commercial Code rule on reserving rights (Section 1-308) does not apply to a full-payment check, so the notation generally does not stop the discharge.

New York is the best-known exception. Its courts have long allowed a creditor to cash a full-payment check and still pursue the balance, but only if the creditor clearly reserves its rights before or when it cashes the check. A letter sent afterwards is too late. Some other states have adopted the rule with changes, and courts read it differently. If your customer is in a state where the rule may differ, talk to an attorney before you rely on it.

When cashing the check does not settle the debt

Under the UCC rule, there are situations where the balance survives even after the check is cashed:

• No real dispute. If the amount was fixed and the customer had no good-faith complaint, a lower check with a “paid in full” note does not erase what they owe. You may still have to prove that later, so keep the signed order, the agreed price and the delivery records.
• It went to the wrong address. A business can send its customers a clear written notice, a reasonable time before the check arrives, naming a person, office or address for communications about disputed debts. If the full-payment check was not sent there, the debt is not discharged by cashing it.
• You pay the money back within 90 days. If you cashed it by mistake, the rule generally lets you undo the settlement by refunding the amount of the check within 90 days. This option is not available to a business that has already sent the dispute-address notice above.

There is an important limit on the last two. If you, or an employee directly responsible for the disputed bill, knew the check was offered as full payment a reasonable time before it was deposited, the debt is discharged anyway. A deposit clerk who simply processes the check usually does not count. Those protections are for checks that slip through, not for checks you knowingly deposit.

What to do with a “paid in full” check

1. Hold it. Do not deposit it, and do not let a lockbox or mobile deposit process it. Make a copy of the front, the back and anything sent with it.
2. Decide whether the amount works. Compare the offer with what you are owed, the strength of the customer’s complaint, and what it would cost to collect the rest.
3. If you will not accept it, send it back promptly. Return the check with a short letter saying you do not accept it as payment in full, and ask for payment of the balance or of the amount the customer does not dispute. Keep proof of delivery.
4. Put any deal in writing. If you agree to a reduced amount, write down the amount, the due date and what happens if it is not paid, and have both sides sign before any money changes hands.
5. If it was already cashed, act quickly. Check where it was sent and who saw it. Ask an attorney right away whether the 90-day refund option applies to you.

Watch for the same wording on other payments. The UCC rule above covers checks and similar instruments, but a “full and final” note on a card payment or bank transfer can still raise the same argument under general contract law. Respond in writing right away that you do not accept it as payment in full, and ask an attorney whether to refund it.

Protect your business before the next check arrives

• Name a dispute address. On your credit application, invoices or statements, state clearly that communications about disputed debts, including any payment offered as full satisfaction, must go to a named person or address. Have an attorney approve the wording.
• Train the people who open the mail. Anyone who handles deposits should flag any check marked “paid in full,” “final” or “settlement” before it is deposited.
• Answer complaints in writing. Document the customer’s complaint and your response. If the dispute is not genuine, your records are what will show it.
• Act before balances age. The longer an invoice sits unpaid, the more likely a customer is to offer a low “full payment” check. See when to place a past-due account.
• Get guarantees in place. A signed personal guarantee on the credit application gives you another place to collect if the business stops paying.

How Snap Debt Recovery helps

A customer who sends a short-pay check is usually telling you two things: they dispute part of the bill, and they want this over. That is often the moment to bring in a third party. Our commercial collections team reviews the invoices and the dispute, and negotiates with the debtor toward full payment or a written settlement you approve. Where the balance justifies it, an affiliate attorney can review the claim for litigation.
