A recurring rejection pattern we see on 810 invoices: the SKU billed does not match the SKU that actually shipped.
It sounds like a data entry problem. Usually it traces back further, a substitution made at the warehouse level that never made it back into the system generating the invoice. The invoice is technically correct against what the order system believes happened. It just does not match reality.
Same root cause pattern as most EDI rejections we diagnose: two systems that were supposed to agree, quietly drifting apart.
