The key is treating each platform's payout as a settlement figure to reconcile, not as your actual sales figure — Amazon, Etsy, eBay and Shopify Payments each net off fees, refunds and sometimes VAT before paying you, so the number that lands in your bank account is never the same as your gross sales, and if you record bank deposits as "sales," your turnover and profit will both be wrong.
Doing this properly means recording gross sales, fees, and refunds separately for each channel, then reconciling the net figure against what actually hit your bank account — which is tedious done manually across several platforms, and is exactly what tools like A2X or Link My Books exist to automate by pulling structured settlement data into your accounting software channel by channel. Without this, sellers running multiple channels typically discover at year end that their bookkeeping and their actual bank balance don't line up, and untangling months of blended multi-channel transactions after the fact is far more work than setting it up properly from the start. If you're currently just recording what hits your bank account across two or more platforms, that's worth fixing at the next opportunity rather than living with it until it becomes a real problem.
We set up proper multi-channel reconciliation for online sellers, so your books and bank balance actually line up.
