The Procure to Pay Cycle and Three-Way Matching
The chain from needing something to money leaving the company, and the matching mechanism that stops a business paying for goods it never received.
Procure to Pay (P2P) is the spending cycle: from the moment somebody needs something to the moment the supplier is paid. It is the standard teaching example because every step produces a document, and those documents lock into each other so that no money leaves without a basis.
The steps and their documents
- 01Purchase Requisition — an internal request from the department that needs something.
- 02Approval — tiered sign-off according to value and company policy.
- 03Purchase Order — the formal order to the supplier; it becomes a binding commitment.
- 04Item Receipt — goods arrive at the warehouse, stock increases and the time is recorded.
- 05Vendor Bill — the supplier's invoice is recorded as a liability.
- 06Bill Payment — payment is made, the liability clears, cash decreases.
Three-way matching
Before a bill is paid, three documents are compared: the Purchase Order (what was ordered), the Item Receipt (what actually arrived), and the Vendor Bill (what is being charged). All three have to agree on item, quantity and price.
| Situation | Meaning | Action |
|---|---|---|
| PO 100, Receipt 100, Bill 100 | A clean match | Clear for payment |
| PO 100, Receipt 80, Bill 100 | Billed for more than arrived | Hold; confirm the balance with the supplier |
| PO 100, Receipt 100, Bill 120 | Price or quantity differs from the order | Hold; request a corrected bill |
| PO 100, Receipt 120, Bill 120 | More received than ordered | Requires approval of the excess |
Tolerances are usually allowed within small limits — a price difference under a set percentage may pass automatically. That threshold is a business policy, not a technical decision: finance sets the number, the system merely enforces it.
