The Best Way to Merge Etsy and Amazon Seller Central Data for Multi-Channel Reconciliation
If you're doing multi-channel 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 Etsy file first. The first time you see this file shape, you map each of its columns to your target list.
- Import the Amazon Seller Central 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 multi-channel reconciliation.
What actually goes wrong if you do this by hand
Etsy gives you Sale Date, usually already in your local timezone, while Amazon Seller Central gives you a purchase date/time column stamped in UTC, not your local time — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, Etsy's export listing titles are included in full and often contain commas, which can shift columns if opened carelessly in Excel, and Amazon Seller Central's reports differ noticeably between the 'All Orders' report and the Payments/Settlement report — totals rarely match at a glance. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for multi-channel reconciliation actually come from.
Why it matters for multi-channel reconciliation
Reconciling orders across channels means matching rows that were never designed to be compared side by side.
