A2X is ecommerce accounting software for Amazon sellers and their accountants that automates the reconciliation of marketplace payouts into accounting platforms. It generates categorized summary entries for each Amazon settlement, breaking down sales, fees, refunds, shipping income, and taxes, then posts them to QuickBooks Online, Xero, Sage, or NetSuite so that deposits match cleanly with bank transactions.

A2X fits into the bookkeeping side of a seller's workflow rather than operational areas like inventory planning or PPC. It is focused on accurate, settlement-based accounting across Amazon, Shopify, eBay, Etsy, and Walmart, and also supports COGS entries and multi-currency sellers. Sellers running multi-channel operations should verify which plan tier covers their combination of marketplaces and monthly order volume.
