What you receive

  • Mismatch-first queue ranked by absolute fee discrepancy, then charge size
  • Recomputed unit volume, billed volume, base fee, and aged surcharge per row
  • Billed-volume check whenever the seller supplies Walmart's reported volume
  • Overcharge exposure isolating only rows charged above the recomputed fee
  • Per-billing-month reported, recomputed, discrepancy, and mismatch summaries

Who it is for

WFS sellers, agencies, and finance teams auditing a month of storage charges without opening each SKU's fee detail or trusting an embedded rate table.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday calculates only from the seller-supplied row references, SKUs, optional GTINs, billing months, unit dimensions or cubic feet, unit counts, per-cubic-foot rates, and reported fees you provide—never buyer, order, address, bank, or payment-instrument data. It reads no Walmart account, API, rate card, or report and verifies no figure. A mismatch is a difference between your own reported and recomputed numbers, not proof that Walmart's measurement or charge is wrong, owed, or recoverable. Friday does not publish listings and never opens a case, files a dispute, requests a remeasurement, or changes an order, listing, price, inventory, or seller account. A human must verify the live charge records and Walmart's current WFS pricing.
