About

Built by a seller, for sellers

TransactionMerge exists because the problem it solves is real — and frustrating. Manually reconciling eBay payout statements against FreeAgent invoices every month is tedious, error-prone, and just not how you should be spending your time.

The problem

eBay sellers using FreeAgent for their accounts have a gap: eBay doesn't integrate directly with FreeAgent the way Amazon does. That means manually downloading transaction reports, working out which sales correspond to which payout, splitting out fees and postage, and entering it all by hand — or paying your accountant to do it.

The solution

TransactionMerge connects directly to both eBay and FreeAgent via their official OAuth APIs. It runs automatically every day, pulling your eBay transactions and posting them to FreeAgent as invoices (for sales), bills (for fees and postage), and credit notes (for refunds) — all dated correctly, all mapped to the right categories in your FreeAgent chart of accounts.

The detail that matters

The thing that separates this from a basic "dump everything in" tool is the accounting knowledge baked in. Cash-basis sellers (most sole traders) need their income dated to when the money actually arrived in their bank account — the eBay payout date — not when the sale happened. TransactionMerge's payout-date mode does exactly that, matching each transaction to the payout that swept it.

VAT-registered sellers get per-line VAT breakdown. Promoted Listings fees go to Cost of Sales, not Admin Expenses. Postage goes where your accountant expects it. The 4-bucket category system mirrors what FreeAgent's own Amazon integration does — so if you've used that, this will feel familiar.

What we care about

Security first
OAuth tokens are encrypted at rest (AES-256-GCM). No passwords are ever stored. Sessions expire after 10 minutes of inactivity.
Accounting correctness
The sync follows UK HMRC guidance for self-employed sellers. We care about getting the debit and credit on the right side.
Set and forget
Once configured, the sync runs daily without you touching it. Re-syncs are idempotent — run them as many times as you like.
No bloat
This is a focused tool. It does one thing well. No CRM, no invoicing, no cash-flow forecasting — just eBay → FreeAgent sync.
Beta status — TransactionMerge is currently in open beta. The core sync is working and used in production by real sellers, but some features (billing, multi-connection VAT) are still being finalised. The 14-day trial is free with no card required.
