Procurement and Supply Workflow and Systems

This domain tests the end-to-end workflow from requisition to payment and the systems that control it. Expect questions on purchase orders, goods receipt, invoice matching, master data, approval limits, segregation of duties, e-procurement and process KPIs. The exam favours process logic and control weaknesses.

Core rules and concepts

  • P2P flow: need/requisition → approval → PO → goods/services receipt → invoice → three-way match → payment → reconciliation.
  • Three-way match compares PO, goods receipt note (GRN) and invoice for quantity, price and terms. Two-way match may apply to services with acceptance.
  • Master data: supplier record, item/material master, price conditions, payment terms. Bad master data causes duplicate suppliers, wrong prices and failed matches.
  • Controls: approval limits, segregation of duties (requester ≠ approver ≠ payer), audit trail, no PO no pay.
  • Duplicate invoice checks compare supplier, invoice number, amount and date before payment.
  • System access: role-based permissions and periodic review prevent unauthorised changes.
  • E-procurement: e-tendering, e-catalogues, punch-out, EDI, workflow. Systems should enforce rules, not just store documents.
  • KPIs: requisition-to-order cycle time, PO accuracy, invoice match rate, cost per transaction.

Worked example

A PO is raised for 100 units at £100, total £10,000. The GRN records 95 units. The invoice arrives for 100 units at £10,000. The three-way match fails on quantity: 95 received × £100 = £9,500. Hold £500 and ask the supplier for a credit note for the shortfall, or accept the missing 5 units later and pay the balance. Do not pay the full invoice. Reasoning: payment is for goods or services received and accepted, not merely ordered. If the invoice is paid, recovering the £500 becomes a credit-control task.

Traps that cost marks

  • Paying from an invoice without a GRN.
  • Changing master data without approval.
  • Letting one person create a supplier and release payment.
  • Assuming an ERP prevents fraud.
  • Ignoring GRN timing.
  • Treating e-procurement as only a website.
