Buyers should preserve the original quote and record every subsequent change in a separate, dated written entry linked to that quote. Each entry should state the previous and revised terms clearly, rather than merely noting that the document was “updated.” At the invoice stage, buyers should check that the pro forma invoice identifies their reference and the items quoted and provides detailed order information.
What a change record should contain
A clear change record lets readers compare the issued quote with later revisions without reconstructing the document history.
| Field | What to document |
|---|---|
| Original document | Quote reference, issue date, and version |
| Change request | Date requested and the exact change proposed |
| Previous terms | Scope, quoted items, exclusions, pricing, and payment terms as originally stated |
| Revised terms | The replacement wording or item details, with all affected fields highlighted |
| Effect of the change | Which parts remain unchanged and which no longer apply |
| Written response | The revised quote or confirmation received, including its date and version |
| Status | Pending, accepted, rejected, or superseded |
These fields are documentation practices, not requirements established by the cited source. Buyers may adapt the format to their own records and contractual arrangements.
Keep the document history readable
Do not overwrite the issued quote or remove an earlier version. Add a new revision or change record and link it to the original document. If several changes occur, preserve them in sequence so that each revision can be compared with the terms that preceded it.
A useful entry identifies the exact affected text. For example, it should show the former item description beside the replacement description and state whether the change affects scope, exclusions, price, or payment terms. If a category remains unchanged, saying so can prevent later uncertainty.
Written acceptance should also be retained with the relevant revision. That record shows which document the buyer treated as current without claiming that the record itself creates a particular legal right.
Check the pro forma invoice
The U.S. International Trade Administration says a pro forma invoice should identify the buyer’s reference and the items quoted. It also recommends providing as much order information as possible so arrangements can be made efficiently.
Buyers can therefore check the invoice for:
- The correct buyer reference
- The items included in the quote
- Detailed descriptions of the order
- Consistency with the latest documented revision
- Clear treatment of any scope, exclusion, pricing, or payment-term change
Any mismatch should be recorded in writing and reconciled against the quote history rather than corrected only through an informal conversation.
What buyers must still confirm
The cited guidance supports invoice-content checks; it does not establish a universal procedure for changing an issued quote. It does not determine whether a particular change form, deadline, contract clause, or regulatory rule applies.
Buyers must still confirm the governing contract, the accepted revision, applicable institutional or trade requirements, and whether every change has been reflected in the final invoice documentation.
