The Best Way to Merge Facebook Marketplace and Bonanza Data for Profit Tracking

If you're doing profit tracking 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 Facebook Marketplace file first. The first time you see this file shape, you map each of its columns to your target list.
  3. Import the Bonanza 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 profit tracking.

What actually goes wrong if you do this by hand

Facebook Marketplace gives you an order date recorded through Meta's commerce backend, while Bonanza gives you a sale date shown in the seller's account timezone — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, Facebook Marketplace's export many sellers use Marketplace only for listings with no built-in checkout, so exports may only exist via a connected store's own platform, and Bonanza's fee amounts differ per listing based on optional ad placement, so two otherwise-identical sales can show different fee columns. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for profit tracking actually come from.

Why it matters for profit tracking

Comparing profit margins across channels only works if fees, shipping, and item totals are broken out the same way in every row.
