The Best Way to Merge eBay and Wix Data for Inventory Reconciliation
If you're doing inventory reconciliation by hand right now, here's the fastest path from "two exports" to "one usable sheet," and why the manual version keeps breaking.
Step by step
- Decide your target columns once. Most people settle on Date, Channel, Order ID, and Total — set that up in CSV Experts and you won't redo it.
- Import the eBay file first. The first time you see this file shape, you map each of its columns to your target list.
- Import the Wix file the same way. Its columns get mapped once too — after that, every future file with this shape merges with no extra clicks.
- Check the merged totals. Dates and numbers are normalized automatically, so a European "24,00" and a US "24.00" both land as the same value.
- Export. CSV or Excel, ready for inventory reconciliation.
What actually goes wrong if you do this by hand
eBay gives you Sale Date shown in the seller's local time, while Wix gives you a Date Created column — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, eBay's export the seller hub export format changed more than once, so column names can differ depending on when the report was generated, and Wix's product options (size, color) are appended into the item name rather than given their own column. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for inventory reconciliation actually come from.
Why it matters for inventory reconciliation
Matching units sold against inventory counts requires the same product and quantity columns across every channel's export.
