Merge Etsy and eBay Sales Data for Tax Prep in Australia
At tax time you need total revenue by channel without hand-fixing each export's columns first. In Australia, that also means accounting for GST: GST is a flat 10% once you're registered, but is only owed above the annual registration threshold.
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 in mind, so getting from "two raw files" to "Australia-ready numbers" means normalizing dates/totals first, then applying your own GST 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 AUD).
- 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 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.
