Catch fast-shipping coverage disappearing before your buyers do.
Included in the $9.00 Shelf Kit
Walmart Marketplace sellers and fulfillment teams auditing large catalogs for silent Two-Day or Three-Day coverage loss between weekly Shipping Program exports before a human investigates.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday compares only the SKU, publish status, lifecycle status, two-day and three-day participation, template, coverage area, and optional recent sales and contribution you supply for two snapshots—never buyer, order, address, tracking, or contact fields. It reads no Walmart account and verifies no field. An observed coverage loss does not prove program ineligibility, a Walmart defect, a policy breach, or an account-health outcome. Friday does not publish listings and never changes a template, program enrollment, fulfillment setting, inventory, or listing. A human must verify the source snapshots and current program status.
