Match every fulfilled unit to your rate card and expose charge differences.
Included in the $9.00 Shelf Kit
WFS sellers, agencies, and finance teams checking a redacted fulfillment-fee export against their own current pick-and-pack rate card before a human reviews source item measurements and charges.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday performs arithmetic only on seller-redacted references, SKUs, dates, size tiers, weights, fulfilled units, reported charges, and the separate rate-card bands and thresholds you supply. It reads no Walmart account, WFS report, invoice, item measurement, or current rate table and infers no dimensional-weight, oversize, apparel, hazardous-material, minimum, peak, fuel, tax, or other unsupplied rule. A difference is a supplied-field review lead, not proof that Walmart charged incorrectly or that a credit is due. Friday files no dispute, does not publish listings, and changes no item, tier, shipment, inventory, fee, listing, or seller account.
