The Best Way to Merge Amazon Seller Central and Reverb Data for Xero Import

If you're doing xero import 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

  1. 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.
  2. Import the Amazon Seller Central file first. The first time you see this file shape, you map each of its columns to your target list.
  3. Import the Reverb file the same way. Its columns get mapped once too — after that, every future file with this shape merges with no extra clicks.
  4. 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.
  5. Export. CSV or Excel, ready for xero import.

What actually goes wrong if you do this by hand

Amazon Seller Central gives you a purchase date/time column stamped in UTC, not your local time, while Reverb gives you an order date column specific to the marketplace's order dashboard — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, Amazon Seller Central's export reports differ noticeably between the 'All Orders' report and the Payments/Settlement report — totals rarely match at a glance, and Reverb's used mostly for musical instruments/gear, so price ranges and shipping costs vary far more per row than typical retail exports. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for xero import actually come from.

Why it matters for xero import

Xero's bank/sales import works best with a single uniform sheet, which is hard to get directly from two different platforms' raw exports.
