Client trying to change terms after the job is finished—what can I do?

Next, gather proof: signed scope, invoices, delivery records, photos, time logs, and messages about payment. A clean paper trail makes your case stronger.

Try a professional approach first. Send a polite reminder with the balance and a due date. If needed, send a demand letter that cites the contract and sets a firm deadline. Many disputes resolve once you show you’re organized and serious.

If payment still doesn’t come through, check your contract. It may allow late fees, interest, or require mediation or arbitration before going to court.

For smaller amounts, small claims court is often quick and affordable. Bigger claims may need a civil lawsuit instead.

Rules on late fees, small claims limits, and demand letters vary by state, so it’s a good idea to talk to a Legal Pro about your options.

What to consider in your specific situation

Every payment dispute is different and may depend on a few key factors:

• Clarity of your contract and payment terms.
• Proof of completed deliverables.
• Any written change requests or approvals.
• State rules on contracts and collections.
• Business impact of further delay.
