A2X and Link My Books integration
UK sellers on Amazon, Etsy or eBay get paid in lump-sum payouts that hide fees, refunds and VAT. Finbryn connects A2X or Link My Books to Xero or QuickBooks so each payout splits into sales, marketplace fees and refunds, with UK VAT treated correctly on marketplace-collected sales.

Why marketplace payouts mislead a UK seller
A single Amazon or Etsy payout landing as one bank deposit hides the sales figure, the marketplace fees, refunds and any reserve held back. For a UK seller close to the £90,000 VAT registration threshold, that single-number view can hide the point at which registration actually becomes due, since taxable turnover is based on sales, not what lands in the bank after fees.
What the integration covers
We connect A2X or Link My Books to the marketplace and to Xero or QuickBooks Online, then map the chart of accounts for gross sales, marketplace fees, shipping income, refunds and reserves. Historical settlements get imported and reconciled to marketplace statements during onboarding rather than starting from a blank slate. Since some marketplaces now collect and remit VAT on behalf of overseas sellers under UK VAT rules, the mapping distinguishes marketplace-collected VAT from VAT the seller still needs to account for directly.
Ongoing reconciliation
Once live, each payout gets reconciled monthly against the summarised entries A2X or Link My Books produces, so the profit and loss reflects actual margin per sale rather than a lump deposit that overstates or understates the picture depending on the period's refund activity.
Where this fits with VAT and MTD
Since all VAT-registered businesses already need digital links under Making Tax Digital, marketplace integration is often the single biggest fix to a UK ecommerce seller's VAT accuracy, ahead of anything the bookkeeping itself changes. It also feeds straight into monthly management accounts once the mapping is stable, since gross sales, fees and refunds are already split correctly by the time the close happens.
Questions
Frequently asked questions: A2X and Link My Books integration
Does A2X handle UK marketplaces like Amazon.co.uk and Etsy UK?
Yes, A2X and Link My Books both support the main UK-facing marketplace accounts; check current coverage against your specific channel before we start.
How does this affect our VAT registration threshold?
We map gross sales, not net-of-fee payouts, into the accounts, which gives an accurate read on taxable turnover against the £90,000 registration threshold.
Do you handle historical settlements from before we started using A2X?
Yes, historical settlements get imported and reconciled to marketplace statements as part of onboarding, so the trading history is not left with a gap.
How does A2X handle a marketplace settlement that spans two accounting periods?
A2X splits the settlement so sales, fees and refunds land in the accounting period they actually relate to, rather than the period the payout happened to arrive in, which matters for an accurate month-end close when a settlement period crosses a month boundary.
Can Link My Books or A2X handle returns and refunds from Amazon or Shopify separately from sales?
Yes, refunds are broken out as their own line rather than netted silently against gross sales, so your reports show actual sales volume and actual refund volume as two distinct figures, which matters if refund rate is something you track.
Why can't I just record the marketplace payout as one deposit?
A single deposit hides sales, fees, refunds and reserves inside one number, which understates revenue and overstates or understates expenses depending on the period.
Which marketplaces does A2X support?
Amazon, Shopify, Etsy, eBay and Walmart are the ones we connect most often; check current coverage against your specific channel before we start.
