Post vendor invoice against PO or GR
Price or quantity mismatch
Goal: stable procurement and stock transparency.
Typical stakeholders: buyer, warehouse lead, inventory controller.
KPIs to watch: purchase cycle time, GR/IR aging, stock accuracy.
Invoice is blocked because quantity or price differs from PO/GR.
Consultant note: Check PO, GR, and invoice values in one flow; fix root mismatch before manual unblocking.
Problem: Invoice gets blocked due to quantity/price variance against PO/GR.
Diagnosis: Review PO item, GR quantities, invoice values, and tolerance keys in invoice verification.
Resolution: Resolve source mismatch first (PO/GR/invoice), then repost or release according to policy.
