Goal
Connect request, approval, purchase order, supplier commitment, receipt and inspection, invoice and three- or four-way payment match as one task.
Risk / exception
A verbal supplier commitment cannot replace ERP/SRM. Freeze payment and create a difference task for unreleased quality, quantity or price mismatch, or duplicate invoice.
Close condition
The request has demand evidence; the PO is authorized; receipt and quality are read back; the invoice matches; bank payment has a receipt; project-cost attribution is correct.
Next safe action
Choose one long-lead item and establish a single business key across budget, PO, inspection, invoice and payment.
