A product cost record is easier to review when each Amazon charge has its own category. Referral, fulfillment, storage, inbound and optional program charges should not be hidden inside a single unexplained estimate.
Establish the fee context
- Record the seller store, settlement currency, product category and fulfillment program.
- Retain the packaged dimensions and weight used for the estimate.
- Save the current estimate with the date of the check and the product identifiers.
- Add actual inbound freight and preparation costs from the relevant invoices.
- Keep optional program charges separate so their purpose remains visible.
Amazon publishes separate Canadian pricing and US fulfillment-fee guidance. Use the applicable store and current fee information instead of converting an old table from another country.
Reconcile actual charges
Match account charges to the same product, period and transaction type. Investigate a changed measurement or classification before assuming the amount is wrong. Preserve the evidence and any support-case identifier.
Update the cost record when its underlying inputs change. The result should explain the product's current economics; it should not imply a fixed saving from a fee check or use unsupported market-wide cost increases.
