What to do if…
a client disputes completed work and stops payment while deadlines are still approaching

Short answer

Stop doing additional work until the dispute and payment status are clear in writing, and send a calm “what was delivered + what’s disputed + what happens to deadlines” message today. Preserve evidence immediately, especially if the client can trigger a payment dispute through a platform or credit card.

Do not do these things

Do not keep working for free to meet a deadline while payment is being withheld.
Do not send threats, insults, or accusations—assume messages could become evidence.
Do not admit breach or “non-delivery” in writing just to de-escalate.
Do not hand over extra files, admin access, or additional deliverables unless it’s part of a written resolution.
Do not retaliate by deleting work, disabling systems, or locking the client out—avoid creating counterclaims.
Do not let urgency push you into open-ended scope (like unlimited revisions) while payment is frozen.

What to do now

Create one “evidence folder” and freeze the timeline.
Save the contract/SOW, change requests, approvals, invoices, delivery emails, messages, meeting notes, version history, and exactly what you delivered. Write a simple timeline: agreed scope → changes → deliveries → approvals → invoice → dispute.
Check your contract for acceptance, disputes, suspension, and deadlines.
Identify what counts as “completed,” how changes are approved, and whether you can pause work for non-payment. If you used a platform (marketplace/invoicing tool), also review its dispute rules and response windows.
Send one structured message that forces clarity (today).
Include:
- what was delivered, with dates/links
- any written approval/confirmation (quote it)
- a request for a written, itemized list of what they say is wrong and how it differs from the agreed scope
- whether they dispute all amounts or only part
- your immediate position: work is paused until (a) undisputed payment is received and (b) disputed items + acceptance criteria are defined
- deadline impact: “With work paused, the schedule shifts; the earliest next deliverable date is ___.”
Ask for immediate payment of the undisputed portion.
If they’re withholding everything, ask them to pay what’s not in dispute now and separate the rest into a punch list with due dates and acceptance criteria.
If the client paid by credit card or through a platform, treat disputes as time-sensitive.
Respond through your payment processor/platform’s dispute workflow right away and upload delivery proof and approvals. (Separately, credit-card billing error rights for cardholders can involve strict timelines—commonly 60 days from the statement—so move promptly to avoid “default loss” outcomes.)
Protect your work product and access safely (without retaliation).
Back up your files, preserve version history, and document any client access you’ve granted. Keep hosted services stable while you clarify payment/scope; avoid sudden shutdowns that can be framed as harm.
Make a clear stop/go decision on approaching deadlines.
- Go only if they pay and confirm (in writing) what “done” means for the next milestone; or
- Stop and state you cannot commit to deadlines while payment is withheld and requirements are disputed.
Prepare a simple demand letter as your next escalation step (if they still won’t pay).
Keep it factual: what you provided, what you’re owed, what’s disputed, and a deadline to pay/respond before you escalate. Avoid legal claims or penalties you’re unsure about.
Choose an escalation lane that fits your relationship.
- For many unpaid-invoice disputes, small claims court in your state may be an option (limits and procedures vary).
- If this is actually wages owed by an employer (employee or misclassification situation), contact the U.S. Department of Labor Wage and Hour Division to file a complaint.

What can wait

You do not need to decide today whether to sue, hire a lawyer, or use a collection agency.
You do not need to rebuild your entire contract or pricing model right now.
You do not need to respond instantly to every message—one clear written update is safer than rapid negotiation.
You do not need to keep producing new deliverables while the definition of “done” is disputed.

Important reassurance

This kind of dispute spikes stress because it combines money, reputation, and time pressure. Pausing work, documenting what happened, and forcing clear written definitions is a normal professional response that prevents a bad situation from compounding.

Scope note

These are first steps to stabilise and protect you. If the amount is large, deadlines are business-critical, or the client is threatening legal action, tailored legal advice in your state may be appropriate.

Important note

This is general information, not legal advice. Contract rights, small claims limits, and payment-dispute procedures vary by state and by the contract and payment method you used. If you’re unsure whether this is an unpaid-invoice dispute or unpaid wages from employment, pause and identify which relationship you’re actually in before taking formal steps.
