The Best Way to Merge Walmart Marketplace and Wayfair Data for QuickBooks Import

If you're doing quickbooks 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 Walmart Marketplace file first. The first time you see this file shape, you map each of its columns to your target list.
  3. Import the Wayfair 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 quickbooks import.

What actually goes wrong if you do this by hand

Walmart Marketplace gives you an Order Date column separate from the ship-by date, while Wayfair gives you a purchase order date distinct from the ship date required by Wayfair's supplier terms — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, Walmart Marketplace's export each order line can appear as its own row with a repeated order ID, similar to Shopify's line-item export, and Wayfair's built for suppliers rather than direct-to-consumer sellers, so column names lean toward logistics (PO, ship window) rather than retail checkout fields. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for quickbooks import actually come from.

Why it matters for quickbooks import

QuickBooks expects a consistent column layout for imported transactions — mismatched headers between channels usually mean manual cleanup before import.
