Client Wants More Work but Hasn’t Paid

Direct answer: Review the agreement, unpaid balance, promised dates and value of the next phase before accepting more work. If continued delivery materially increases exposure, state that the next phase will pause until the overdue invoice is cleared, then explain how work will resume after payment.

Assess the exposure before replying

How much is currently unpaid?
How many days overdue is the invoice?
Has the client missed a specific payment promise?
Would the requested work create another unpaid invoice?
Does the agreement permit suspension or require notice?
Is the balance disputed or merely delayed?

Professional Pause wording

Subject: Project schedule and invoice #[number] Hi [Name], To keep the project properly resourced and avoid increasing the outstanding balance, we will pause the next phase until invoice #[number] for [amount] is cleared. Once payment is confirmed, we can resume and provide an updated delivery schedule. Please let me know if your accounts-payable team needs anything from us to release payment. Regards, [Name]

When a payment plan is requested

Do not agree verbally and continue at full speed. Record the balance, installment amounts, dates, consequences of a missed installment and whether new work remains paused. Have the arrangement reviewed when the amount or risk justifies it.

Do not bluff

Only state a pause, fee, collection referral or legal step that is consistent with the agreement, applicable requirements and your actual plan.
