The 7-Step Procure-to-Pay Cycle

  1. Purchase Requisition: requestor identifies need, submits formal request with cost center and justification
  2. Approval Routing: rules-based routing by dollar amount, category, and requestor location
  3. Purchase Order Creation: PO generated from approved requisition and transmitted to vendor
  4. Goods / Services Receipt: delivery received and confirmed in system
  5. Invoice Receipt: vendor submits invoice (portal or email)
  6. Three-Way Matching: automated matching of invoice to PO and goods receipt
  7. Payment: matched invoice routes to AP for payment; exceptions flagged for human review

FAQ

Frequently Asked Questions

Procure-to-pay (P2P) software automates the full purchasing cycle from purchase requisition through supplier payment, including PR creation, approval routing, PO generation, goods receipt, invoice matching, and AP payment processing.

The 7 P2P steps: (1) Purchase requisition submitted, (2) Approval routing by amount and category, (3) PO created and sent to vendor, (4) Goods or services received and confirmed, (5) Vendor invoice received, (6) Three-way matching (invoice vs. PO vs. receipt), (7) Payment processed through accounts payable.

P2P automation reduces invoice processing cost from $10 to 15 to $2 to 4 per invoice (60 to 75% reduction). For 5,000 invoices/year, that's $40K to $65K in direct annual savings, plus captured early-payment discounts and reduced duplicate payment risk.

Best mid-market P2P software: Procurify (best overall), Precoro (best value), and Stampli (specialist AP automation). Enterprise: SAP Ariba, Coupa, GEP SMART.
