Merge eBay and TikTok Shop Sales Data for Tax Prep in Ireland
At tax time you need total revenue by channel without hand-fixing each export's columns first. In Ireland, that also means accounting for VAT: VAT at the standard 23% rate applies once registered, with the same EU cross-border thresholds as other EU sellers.
Why eBay and TikTok Shop exports don't line up
- eBay: Sale Date shown in the seller's local time; item subtotal, shipping, and final value fee as separate columns; an Order Number that can bundle multiple items bought together into one row.
- TikTok Shop: an order creation time stamped in UTC; order amount, platform commission, and affiliate commission split into separate columns; a long numeric Order ID.
Neither export is built with VAT in mind, so getting from "two raw files" to "Ireland-ready numbers" means normalizing dates/totals first, then applying your own VAT treatment on top of the merged total — not per platform separately.
How to merge them
- Set your target columns once in CSV Experts (Date, Channel, Order ID, Total, and a Currency column if you sell in more than EUR).
- Map the eBay export, then the TikTok Shop export — each file shape is remembered after the first time.
- Export the merged sheet and apply your VAT treatment to the combined total.
FAQ
Does this upload my sales data anywhere?
No. Everything runs in your browser using JavaScript — your files are never sent to a server.
Does it work for more than two channels?
Yes. Add as many source files as you want; each distinct file layout is mapped once and remembered.
