Merge TikTok Shop and Reverb Sales Data for Quarterly Tax Estimates

Quarterly estimated tax payments depend on knowing real revenue across every channel, not just the platform that's easiest to check.

Why TikTok Shop and Reverb 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.
Reverb: an order date column specific to the marketplace's order dashboard; item price, shipping, and Reverb's selling fee as separate columns, often with international currency conversion involved; an order number distinct per listing sold. Also, used mostly for musical instruments/gear, so price ranges and shipping costs vary far more per row than typical retail exports.

For quarterly tax estimates, 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 Reverb 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.
