Why payout is not the same as profit

Whatnot earnings reflect marketplace transactions, but they do not necessarily include what you paid for the item, packaging, supplies, mileage, equipment, or other operating expenses. Subtracting those costs is what turns payout into an estimated business profit.

Why use the weekly report?

The report includes completed order earnings as well as separate rows for tips, refunds, and additional shipping charges. Summing transaction amounts captures adjustments that a simple percentage calculator can miss.
