Amazon FBA sellers face an accounting problem most generalist accountants don't understand: your payouts are a net figure after fees, refunds, reimbursements, storage charges, and advertising costs have all been deducted. Without proper reconciliation, your books are wrong — and you don't know it. At Elver, we use A2X to automatically reconcile every Amazon payout into Xero, mapping each component to the correct nominal code. That means accurate gross sales, correct fee treatment, and clean COGS tracking — all without manual intervention. We can also handle inventory valuation, ensuring your balance sheet reflects stock correctly at period end. For FBA sellers with complex stock positions across multiple warehouses or markets, this matters enormously for both management reporting and statutory accounts. Whether you're a UK-based seller, an overseas seller with UK VAT obligations, or scaling from one marketplace to many, we'll ensure your Amazon accounting is accurate, automated, and audit-ready.
