Merge Etsy and eBay Sales Data for Sales Tax Reporting in Canada

Sales tax reporting needs order totals broken out consistently by date and location, which rarely matches between two platforms' raw exports. In Canada, that also means accounting for GST/HST: GST/HST rates vary by province, so revenue needs to be attributed by shipping province, not just totalled nationally.

Why Etsy and eBay exports don't line up

Etsy: Sale Date, usually already in your local timezone; Item Total, Shipping, and Etsy fees as separate columns, before tax; a numeric Order ID shared by every item in the same order.
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.

Neither export is built with GST/HST in mind, so getting from "two raw files" to "Canada-ready numbers" means normalizing dates/totals first, then applying your own GST/HST 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 CAD).
Map the Etsy export, then the eBay export — each file shape is remembered after the first time.
Export the merged sheet and apply your GST/HST 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.
