Accounting that agrees with your profit board

The month-end problem is rarely that the books are hard. It is that the accounts say one thing, the profit tool says another, and reconciling the two by hand is the actual work.

Accounting for an Amazon business only works if it agrees with the profit you report and with what Amazon actually paid. SellerFlow keeps invoices, purchase ledger, due dates and bank reconciliation against the same figures the profit board uses, so the books and the operational numbers do not tell two different stories.

One set of numbers, not two

When the bookkeeping and the profit analytics are separate systems fed by separate imports, they disagree — and the disagreement is discovered at the worst possible moment. Here the fees, the purchase costs and the refunds behind the accounts are the same records behind the margin per product.

What it covers

• Purchase invoices, captured and matched to the goods they correspond to.
• Purchase ledger, ready to hand to a bookkeeper without rebuilding it.
• Due dates, so what has to be paid and when is visible before it is late.
• Bank reconciliation, matching what left the account against what was expected.
• Export in a form an external accountant can actually work with.

Tax treatment is configuration

Tax rates and rules differ by marketplace, and they are part of the product's economics, not a formatting detail applied at the end. They are configured per marketplace, which is also what makes the break-even under each price the real one.

Amazon's settlement is the reference

The figures reconcile against Amazon's own transaction report rather than against an internal estimate. The last audit compared 14,559 orders at 0.14% deviation. If the books and the settlement disagree, that is something to find out during the month rather than in April.

Frequently asked questions

Why do my books disagree with my Amazon dashboard?

Usually because they are built from different sources: the dashboard from orders, the books from payouts. A payout covers a period that does not match a calendar month and arrives net of fees, refunds and reserves, so the two only agree if fees and refunds are captured line by line.

What do I need to give my accountant?

Figures that reconcile against Amazon's settlement report, with fees and refunds itemised rather than netted. The methodology page sets out what our reconciliation covers and what it does not. Netted figures are the usual source of the argument at year end, because a single payout number hides the fees and refunds that explain the gap between what you sold and what you were paid.

Does this replace my accountant?

No. It prepares the numbers so that the work your accountant does starts from something reconciled, rather than from a spreadsheet exported at month end. Your accountant still decides how things are booked and what the tax treatment is. What changes is that the conversation starts from figures that already reconcile against Amazon, instead of from an export nobody has checked.
