The Best Way to Merge Squarespace and Reverb Data for Cost of Goods Sold Tracking
If you're doing cost of goods sold 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
- 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 Squarespace file first. The first time you see this file shape, you map each of its columns to your target list.
- 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.
- 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 cost of goods sold tracking.
What actually goes wrong if you do this by hand
Squarespace gives you a Date column in ISO-like format, 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, Squarespace's export customer and shipping address fields are wide, so the money and date columns can end up far to the right of the sheet, 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 cost of goods sold tracking actually come from.
Why it matters for cost of goods sold tracking
Calculating cost of goods sold across channels requires item-level data lined up the same way regardless of where it sold.
