Merge Shopify and Wix Sales Data for Tax Prep in France
At tax time you need total revenue by channel without hand-fixing each export's columns first. In France, that also means accounting for TVA (VAT): TVA reporting follows the same EU distance-selling logic as other EU countries, with revenue split by buyer location above the threshold.
Why Shopify and Wix exports don't line up
- Shopify: a Created At timestamp that includes a timezone offset; a single Total column that already nets out discounts, with tax broken out separately; an order Name like #1001 rather than a numeric ID.
- Wix: a Date Created column; a Total column with tax handling that varies by store region; an Order # formatted as a short number.
Neither export is built with TVA (VAT) in mind, so getting from "two raw files" to "France-ready numbers" means normalizing dates/totals first, then applying your own TVA (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 Shopify export, then the Wix export — each file shape is remembered after the first time.
- Export the merged sheet and apply your TVA (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.
