Pay once · No Friday subscription
Expose minimum-fee effective rates, then check the selling-fee deduction and payout independently.
Included in the $9.00 Shelf Kit
Facebook Marketplace sellers and bookkeepers checking seller-redacted completed shipped-order rows against the selling-fee terms shown in their own source records before a human reviews any payout question.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday performs arithmetic only on seller-supplied completed shipped-order dates, references, listing and SKU aliases, currency, selling-fee basis, percentage, minimum, payout-before-fee, recorded fee, and recorded payout. It reads no Facebook Marketplace account, order, shipping record, payment account, payout record, or fee schedule and verifies no source field. Facebook Marketplace alone determines whether an order is covered, the applicable basis and terms, shipping treatment, refunds, and actual payout. A difference is a bookkeeping review lead, not proof of a wrong charge, missing payout, refund, credit, or amount owed. Friday opens no case, files no dispute, requests no credit, moves no money, changes no listing, shipment, fee, payout, or seller account, and does not publish listings.
