The Best Way to Merge BigCommerce and Faire Data for Multi-Channel Reconciliation
If you're doing multi-channel reconciliation 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 BigCommerce 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 multi-channel reconciliation.
What actually goes wrong if you do this by hand
BigCommerce gives you an Order Date column that includes a full timestamp, 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, BigCommerce's export many optional columns are exported blank depending on store configuration, which can throw off auto-mapping by header position, 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 multi-channel reconciliation actually come from.
Why it matters for multi-channel reconciliation
Reconciling orders across channels means matching rows that were never designed to be compared side by side.
