Procure-to-pay: What is procure-to-pay?

Procure-to-pay is the operational procurement process from purchase requisition through purchase order, receipt, invoice, and payment.

Procure-to-pay (P2P) is the end-to-end process from raising a purchase request to paying the supplier. It is the operational backbone of procurement and AP, and the contract sits at the front of it: the agreement defines the rules, the P2P process executes against them.

80%
Reduction in manual invoice-processing effort possible through P2P hyperautomation, per Gartner. The contracts at the front of P2P set the rules (pricing, payment terms, SLA penalties); the automation downstream relies on that contract data being structured and accessible.

TL;DR
  • P2P is the operational process: request → PO → receive → invoice → pay.
  • The contract is the rulebook at the front of P2P; the rest of the process executes against it.
  • Most P2P leakage happens at the contract-to-invoice reconciliation step.
  • Vallor sits at the contract layer so the rules feeding P2P are clear, current, and citable.

The procure-to-pay process, step by step

1

Purchase request

Business need raised. The request is the entry point and should route to procurement, not directly to AP.

2

Approval routing

Approval chain based on amount, category, and supplier. Approval thresholds should match the contract authority structure.

3

Purchase order issuance

PO created with line items, prices, delivery, payment terms. Should reference the underlying MSA/contract.

4

Goods or services receipt

Delivery confirmed against the PO. Triggers acceptance and starts the payment clock.

5

Invoice receipt

Supplier invoices against the PO. Three-way match (PO, receipt, invoice) is the standard control.

6

Reconciliation against contract terms

Verify pricing matches MSA. Verify SLA performance triggers any credits. Verify discounts and rebates are applied.

7

Payment

Payment per the contract's payment terms (Net 30, Net 45, etc.). Early payment discounts captured where eligible.

How Vallor handles procure-to-pay

1
Read the contract at the front of every P2P processPricing, payment terms, SLAs, rebates, and audit rights all extracted from the source contract.
2
Reconcile actual invoices against contract termsVallor checks invoice line items against the negotiated commercial terms and flags deviations.
3
Surface unclaimed credits and rebatesSLA credits, volume discounts, MFN true-ups, and other entitled adjustments that AP often misses.
4
Power AP automation with structured contract dataVallor feeds the contract data downstream so AP can reconcile and pay accurately without manual lookups.

Where teams trip up

✗
Treating P2P as AP-onlyAP is the back half of P2P. The front half (contract, request, PO) sets the rules. Optimizing AP without fixing the contract layer caps the ROI.
✗
Three-way match without contract matchPO + receipt + invoice match is necessary but not sufficient. Invoice should also match the contract terms. Many AP teams skip this step because the contract data is not accessible.
✗
Ignoring unclaimed creditsSLA credits, volume discounts, and MFN true-ups are commonly not claimed because the contract terms are not visible to AP. Money left on the table.
✗
POs without underlying contractsMaverick POs to suppliers without an MSA bypass the rules and create rogue exposure. Procurement controls should require an MSA for any spend above a threshold.

FAQ

What is the difference between P2P and S2P (source-to-pay)?

P2P starts at the purchase request. S2P starts upstream at strategic sourcing (identifying suppliers, RFx, contract negotiation). S2P is the broader process; P2P is the transactional subset.

Where does contract management fit in P2P?

At the very front. The contract sets the rules — pricing, payment terms, SLAs, rebates — that the rest of P2P executes against. Without accessible contract data, P2P controls are guesswork.

What is three-way match?

The standard P2P control: invoice matches the purchase order, the purchase order matches the goods/services receipt, and the receipt matches the actual delivery. All three must align before payment.

How does AI improve P2P?

Gartner reports up to 80% reduction in manual invoice processing through hyperautomation. The wins come from automated three-way match, anomaly detection, and reconciliation against contract terms.

How does Vallor fit into P2P?

Vallor sits at the contract layer at the front of P2P. It feeds structured contract data downstream so AP can reconcile against actual terms, surface unclaimed credits, and automate the routine work.
