For accountants managing Amazon sellers as clients in Xero, the core problem is that Amazon does not issue standard invoices — it issues bi-weekly settlement statements that compress two weeks of transactions into a single bank line. Xero's bank rules can categorize the lump deposit, but they can't split it into revenue, fees, and refund components automatically. The integration fix is to pull Amazon settlement data into Xero before it hits the bank feed: the automation reads each settlement report line item and creates the corresponding Xero transaction with the right account code, tax rate, and date. This creates an accurate audit trail that matches the actual bank deposit and makes VAT reporting on marketplace sales straightforward rather than approximate.
