A fee check should begin with the product measurements and program information used by the account. An estimate, a billed charge and a carrier invoice are separate records and should remain distinguishable.
Check the estimate inputs
- Identify the seller store, currency, product category and fulfillment program.
- Retain the packaged measurements and weight, including who measured them and when.
- Compare those inputs with the product information shown in the account.
- Save the current estimate and the date of the check.
- Keep preparation and inbound freight invoices outside the fulfillment-fee estimate.
Use Amazon's US fee reference or the applicable Canadian pricing information. The store and current program terms determine which guidance is relevant.
Investigate an actual charge
Match the charge to its transaction, SKU and period. If the product data differs from the supporting measurements, preserve both records and identify the relevant account process for a correction.
Record the support-case identifier and final outcome beside the original charge. Updating a cost file can improve the quality of a decision, but it should not be used to assert a saving before the account evidence establishes what changed.
