The problem

Approving invoices is too late to control spend.

By the time an invoice reaches AP, the money is already committed. Off-contract buying, maverick spend, and budget overruns happen upstream, at the requisition and PO stage, where most finance teams have no automated control.

Chasing approvals by email and rekeying POs into the ERP slows the whole cycle and hides the numbers until month-end.

How it works

One automated cycle, from request to payment.

01

Requisition

Staff raise a request against the right budget and cost centre. Rules catch off-contract and over-budget items before they become commitments.

02

Purchase order

Approved requisitions become POs automatically and post to your ERP. No rekeying, no email chains.

03

Budget check

Every commitment is checked against live budget before it is approved, so finance sees committed spend in real time.

04

Goods receipt

Receipts are logged against the PO so quantities and prices are confirmed before any invoice is paid.

05

Invoice and three-way match

Supplier invoices are captured and matched to the PO and goods receipt. Clean matches pass straight through. Exceptions route to the right approver with the full history attached. See the invoice detail in AP automation.

06

Payment and accounting

Approved invoices are scheduled for payment and posted to the ledger with a complete audit trail.

AP vs P2P

AP automation fixes the invoice. Purchase to pay fixes the spend.

Accounts payable automation speeds up invoice capture, matching, and payment. That removes the data entry, but the commitment was already made.

Purchase to pay adds the front of the cycle: requisitions, purchase orders, and budget control. Finance approves spend before it happens.

If invoices are the only problem you have today, start with AP automation. If you want control over what gets bought in the first place, this is the page.

FAQ

Common questions.

Purchase to pay, also called procure to pay or P2P, is the full cycle from raising a purchase requisition through to paying and accounting for the supplier invoice. It covers requisitions, purchase orders, goods receipt, invoice matching, and payment.

Accounts payable is the invoice part: capturing, matching, and paying supplier invoices. Purchase to pay is the whole cycle, including the requisition and purchase order steps that happen before the invoice. AP is a subset of P2P.

Stratas connects to 100+ ERPs and finance systems, including Sage, SAP, Business Central, NetSuite, Xero, and OrderWise.

No. Many teams start with AP automation and add requisitions, purchase orders, and budget control later. The cycle is modular.
