Sam's Club Code 12: Invoice incorrectly extended / quote price difference.
Sam's Club Code 12 means Sam's Club detected an extension discrepancy (Quantity × Unit Cost ≠ Extended Line Total) or a variance against a buyer quote sheet. It often triggers on Sam's Club invoices when inner club-packs and outer master cases are multiplied incorrectly in the EDI 810.
Why Sam's Club issues Code 12.
- Rounding discrepancy between 4-decimal unit costs and 2-decimal extended invoice totals
- EDI 810 multiplied the case cost by the individual club-pack count
- Promotional quote sheet price differed from the invoiced price
Documents that win.
