Subject: Re: Invoice [#1234], your question on [line item]
Hi [First name], Thanks for flagging this. I have paused the reminders on [#1234] while we sort it out. So I fix the right thing: can you confirm which line items you are questioning and what you expected them to be? If it is [the item you suspect], I have [the approval / timesheet / delivery record] from [date] and can send it over. Everything else on the invoice ($[undisputed amount]) is not in question as I understand it; if you can process that portion now, I will issue a corrected invoice for the rest as soon as we agree. I will have an answer to you by tomorrow either way. Thanks, [Your name]
A dispute is the invoice finally getting someone's attention. The response has four jobs: confirm that reminders have stopped (so the client is not chased mid-conversation), make the objection specific (vague concerns become $600 line items once you ask), separate the undisputed balance so it can be paid now, and commit to a fast answer.
Send it the same day. Disputes that sit for a week harden; disputes answered in hours with the approval email attached usually end the conversation.
What to change
- The evidence you name. If you already suspect which line item it is, say so and name the document you have. It shortens the exchange by a round.
- The undisputed amount. Do the subtraction for them and ask for that portion now.
- The commitment. Tomorrow, or sooner. Then keep it.
What to avoid
- Arguing in the first reply. Get the specifics first.
- Letting the whole invoice wait on one line item.
- Forgetting to actually pause the reminders before sending this.
Common questions
How do you respond to a client who disputes an invoice?
Same day: thank them, confirm reminders are paused, ask exactly which items they question and what they expected, separate the undisputed balance and ask for it to be paid now, and commit to an answer by the next business day.
Should you keep sending reminders during a dispute?
No. Pause all reminders on the disputed invoice until it is resolved, then restart the sequence from a fresh due date on the corrected or confirmed invoice.
Can you ask for partial payment during a dispute?
Yes, and you should. Confirm the undisputed portion in writing and ask for it now; issue a corrected invoice for the disputed remainder once agreed.
