The issue
A price difference can reflect a genuine mismatch, an effective-date issue or an approved change that is not represented consistently across documents.
Documents to gather
- Invoice
- Purchase order
- Approved price change record
- Supplier agreement
- Buyer correspondence when relevant
Review checklist
- Compare invoice and PO unit prices
- Check item and effective dates
- Identify the governing agreement or approved change
- Calculate only the amount supported by the records
- Verify the current dispute route before filing
