The Best Way to Merge WooCommerce and TikTok Shop Data for Year-End Sales Summary

If you're doing year-end sales summary 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 WooCommerce file first. The first time you see this file shape, you map each of its columns to your target list.
  3. Import the TikTok Shop 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 year-end sales summary.

What actually goes wrong if you do this by hand

WooCommerce gives you an Order Date in whatever format your WordPress site's locale is set to, while TikTok Shop gives you an order creation time stamped in UTC — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, WooCommerce's export column layout depends on which export plugin generated the CSV, so two WooCommerce stores can produce different headers entirely, and TikTok Shop's refunded and partially-refunded orders stay in the export with a status column instead of being removed, so totals can overstate revenue if you don't filter by status. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for year-end sales summary actually come from.

Why it matters for year-end sales summary

A year-end summary across channels means twelve months of exports from each platform, all needing the same cleanup before they can be totalled together.
