Vendor invoice
The invoice the seller raises on the marketplace platform for the items in a shipment.
The vendor invoice is the one you raise on Ajio (or whichever marketplace) for the goods you're shipping. It's an internal-to-the-marketplace document — the marketplace uses it to calculate your settlement.
Vendor invoices need to match the SKUs and quantities on the packing slip and the customer invoice. Mismatches here are a common silent-revenue-loss vector: the marketplace pays you for what's on the vendor invoice, not for what's on the actual packing slip. If the vendor invoice undercounts, you eat the difference.
Robnu's document pipeline reconciles vendor invoice ↔ slip ↔ customer invoice at stage 9 of the 11-stage flow. Anything that doesn't reconcile gets flagged before the manifest closes.
