Accounting Software for Amazon Sellers

Amazon money is orders — what sold, to which province, with what tax — and settlements — what Amazon actually deposited, and what it charged to get there: commission, fulfilment, storage, advertising, and the tax on those fees. Books carrying only the first half show a profit you did not make and a clearing account that only ever grows.

SeroBooks posts both, for the same periods. Orders become invoices; each settlement becomes a journal with every fee itemised.

A marketplace buyer paid the marketplace on day one, so that money belongs in a clearing account, not in receivables. Sales push money in; settlements take it out. A clearing balance that rises and falls is a complete set of books; one that only rises means the deposits were never recorded.

That single check catches the most common marketplace bookkeeping failure in about ten seconds.

The destination province sets the rate, so orders are enriched with their ship-to province before posting — an order with no province cannot be taxed correctly, and the flow enforces the order of operations. Marketplace-collected tax is recorded on both sides so the figures net correctly and the return can be explained; genuinely exempt buyers post as zero-rated rather than as errors.

File from the by-province, by-tax breakdown — the shape a return asks for — instead of a marketplace report.

This is the work A2X and Webgility charge for monthly, built into the product and reconciled account-for-account against a real production seller's QuickBooks. Unmapped fees land visibly in a holding account rather than being guessed into an expense — and a new balance there later is the earliest warning that Amazon started charging something new.

Reconcile every payout against its bank deposit and year-end is an afternoon instead of a forensic week.
