Isolate peak storage surcharges from the base monthly fee.
Included in the $9.00 Shelf Kit
WFS sellers, agencies, and finance teams isolating a seasonal storage layer on current seller-supplied statements before a human validates Walmart's live peak window and rate.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday calculates only from the seller-supplied row references, SKUs, optional GTINs, billing months, peak-window confirmations, stored volume, base monthly fees, peak surcharge rates, and recorded peak surcharges you provide. It reads no Walmart account, statement, API, or current fee schedule, embeds no peak window or rate, and verifies no field. The base fee is preserved, not audited; a peak-surcharge difference is arithmetic between your own inputs, not proof of a wrong charge, owed credit, or recoverable amount. Friday opens no case, files no dispute, does not publish listings, and changes no fee, inventory, shipment, listing, price, or seller account.
