See the recorded product workflowDecisions to make before billing
When a client disputes an invoice, another generic reminder can miss the issue. Start by identifying the questioned line, amount, and reason. A rate mismatch needs different evidence from an unapproved scope change or a payment already received.
Keep the original total, confirmed receipts, and disputed portion distinct. This gives both sides a shared balance to discuss and stops the team from chasing an outdated total. Xero's dispute guidance similarly emphasizes understanding the concern, keeping written records, and verifying the invoice against supporting documents.
The following workflow is an operational review, not legal collections advice. It helps assign an owner, decide which messages need review, and preserve a correction or explanation. Do not treat aging alone as a reason to escalate a charge whose basis is still being checked.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Acknowledge and define the question
Confirm the invoice ID and ask which charge is questioned if it is unclear. Summarize the concern neutrally in writing. Name the case owner and the next update date so the client knows when to expect a response.
Reconcile and gather relevant evidence
Check receipts first, then the agreed scope, rate, PO, change approval, timesheet, or acceptance evidence for the questioned line. Review reminders involving the disputed amount while that check is open.
Document the outcome before resuming
Explain a supported charge or approve the appropriate correction through your billing process. Save the client response, adjustment reference, and updated balance. Review the next reminder so it matches the resolved record.

Avoid this
Calling the entire invoice disputed
If the concern is one line, record that line and amount. A clear split supports a more precise conversation than a blanket disputed label.
Avoid this
Deleting the original invoice trail
Preserve the original document and the correction history required by your billing process. A silent edit makes it harder to explain what changed.

Questions people usually have before changing the workflow.
What if payment arrives during the review?
Confirm and allocate it, update the open balance, and continue resolving any remaining question. Do not leave reminders based on the earlier unpaid total.
Can I ask about the undisputed amount?
Discuss it clearly with the client and follow the agreement and appropriate process. This guide does not decide legal payment obligations.
How long should resolution take?
Choose a realistic next update date based on the evidence needed. There is no universal deadline in this workflow; honor your agreement and applicable requirements.
