Amazon keeps 30-40% of your revenue in fees. Most accountants can’t tell you where it goes.
Referral fees, fulfilment fees, long-term storage charges, advertising costs — Amazon takes a cut at every stage. Your general accountant lumps them all together.
Your accountant expenses inventory when you buy it, not when it sells. This destroys your P&L accuracy — you don't know real margins per SKU.
Storage fees, advertising spend, and certain fulfilment charges carry potentially reclaimable VAT on eligible FBA fees. Most accountants miss this entirely because they don't understand FBA fee structures.
Customer returns, lost inventory reimbursements, and damaged stock credits — your books never match Seller Central because nobody reconciles the settlement reports.
See the difference a modern, specialist firm makes, side by side.
