The Best Way to Merge eBay and Faire Data for Monthly Sales Reporting
If you're doing monthly sales reporting 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 eBay file first. The first time you see this file shape, you map each of its columns to your target list.
- Import the Faire 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 monthly sales reporting.
What actually goes wrong if you do this by hand
eBay gives you Sale Date shown in the seller's local time, while Faire gives you an order date shown alongside a separate ship date for wholesale orders — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, eBay's export the seller hub export format changed more than once, so column names can differ depending on when the report was generated, and Faire's quantities are per case/pack rather than per unit, which throws off totals if merged as if it were a retail export. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for monthly sales reporting actually come from.
Why it matters for monthly sales reporting
A monthly sales report across channels needs one date format and one revenue column, not a per-platform patchwork.
