Invoice dispute response letter — when a client challenges your invoice
Use this when a client has disputed an invoice — whether orally or in writing. The goal is to preserve your rights, present your evidence, and get their objection in writing. An undocumented verbal dispute is very hard to resolve or litigate; a written one is not.
Use it for
- Responding to vague or verbal client disputes about invoice amounts
- Situations where part of the invoice is undisputed and you want immediate payment on that portion
- Creating a written record before any escalation or legal step
- Professional services, agencies, and contractors where scope disputes are common
Do not use for
- Situations where you believe the client's dispute is fully valid — just issue a revised invoice
- Simple billing errors (name, amount typo) — correct and reissue instead
- Consumer billing disputes governed by the Fair Credit Billing Act (B2B only)

- {{DISPUTE_CLAIM_SUMMARY}}

- {{DOCUMENTATION_DESCRIPTION}}
- What you are attaching to support the charge: SOW, timesheets, delivery confirmation, approved scope changes, emails confirming authorization, etc.

- The portion of the invoice the client has not disputed. You can request payment of this amount immediately.
