A Neutral Template for Asking a Supplier to Explain an Invoice Difference
State the evidence and question, then request a correction or explanation
The short answer
A useful inquiry is specific and calm: identify the invoice, line, agreed source, and arithmetic difference; ask the supplier to confirm whether a change was authorized or provide a corrected bill. Avoid allegations when the records show only a discrepancy.
How to approach it
Keep communication in the existing vendor channel and maintain the original invoice. Set a reasonable follow-up date, and route contract or legal disputes to the right advisor rather than withholding payment without understanding the agreement.
- Cite invoice number, line, and relevant PO or quote
- Show the calculation and exact question
- Record the response and final resolution
Could this affect your business?
- Who owns this review, and who covers it when they are unavailable?
- Could another team member retrieve the evidence and explain the decision?
- Which part of the process is most likely to be missed during a busy week?
