Merge TikTok Shop and Bonanza Sales Data for Handoff to Your Accountant

Handing raw multi-platform exports to an accountant usually means paying them to do the cleanup you could do yourself in a few minutes.

Why TikTok Shop and Bonanza exports don't line up

TikTok Shop: an order creation time stamped in UTC; order amount, platform commission, and affiliate commission split into separate columns; a long numeric Order ID. Also, 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.
Bonanza: a sale date shown in the seller's account timezone; item price and a Bonanza final value fee that varies by advertising tier chosen per listing; an order ID unique to the marketplace. Also, fee amounts differ per listing based on optional ad placement, so two otherwise-identical sales can show different fee columns.

For handoff to your accountant, that mismatch is exactly what causes hours of manual cleanup every period.

Open CSV Experts and set your target columns once (Date, Channel, Order ID, Total).
Drop in your TikTok Shop export and map its columns once.
Drop in your Bonanza export and map it the same way — both merge into one sheet, normalized.
Export as CSV or Excel. Same-layout files merge automatically next time.
