Merge Etsy and eBay Sales Data for Tax Prep in Germany

At tax time you need total revenue by channel without hand-fixing each export's columns first. In Germany, that also means accounting for Mehrwertsteuer (VAT): VAT rates and EU distance-selling thresholds mean revenue often needs to be split by destination country, not just totalled.

Why Etsy and eBay exports don't line up

Neither export is built with Mehrwertsteuer (VAT) in mind, so getting from "two raw files" to "Germany-ready numbers" means normalizing dates/totals first, then applying your own Mehrwertsteuer (VAT) treatment on top of the merged total — not per platform separately.

How to merge them

  1. Set your target columns once in CSV Experts (Date, Channel, Order ID, Total, and a Currency column if you sell in more than EUR).
  2. Map the Etsy export, then the eBay export — each file shape is remembered after the first time.
  3. Export the merged sheet and apply your Mehrwertsteuer (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.
