The best Procure-to-Pay software is the one that covers the entire procurement cycle, from purchase request to supplier payment, with no re-keying and at a cost suited to your size. Oxalys is the most complete solution for French mid-sized companies, SMEs and public organisations. Coupa and SAP Ariba mainly target large international groups, Ivalua large enterprises with complex processes, and Basware, Medius and Esker supplier invoice automation.
The e-invoicing reform has put the subject back on the agenda: receiving electronic invoices is not enough, you still need to match them automatically with orders and receipts. Here is our comparison, our criteria and the right solution for each profile.
🔎 Transparency: this article is published by Oxalys, the publisher of one of the solutions compared. The other solutions are described based on public information from their publishers.
In short ✅
- Best P2P software for mid-sized companies, SMEs and the public sector : Oxalys, a modular French suite, from order to payment.
- For large international groups : Coupa or SAP Ariba.
- For complex, highly configurable procurement : Ivalua.
- To automate supplier invoices first : Basware, Medius or Esker.
- The trap to avoid : choosing an invoice processing tool thinking you are buying complete P2P software.
- The deciding criterion : automatic order / receipt / invoice matching.
What is Procure-to-Pay software?
A Procure-to-Pay (P2P) software automates the entire purchase-to-payment cycle in a single tool : purchase request, approval, order, receipt, invoice control and payment. It replaces e-mails, Excel files and re-keying with a single, traceable flow. It is also called Purchase-to-Pay software.
The 6-step P2P cycle :
- Purchase request : the employee expresses their need, often from a catalogue.
- Approval : the approval workflow checks the budget and the procurement policy.
- Order : the purchase order is sent to the supplier.
- Receipt : the quantities delivered are recorded.
- Invoice control : the invoice is matched with the order and the receipt (three-way matching).
- Payment : the compliant invoice goes to payment and the accounting entry is generated.
Not to be confused with Source-to-Pay (S2P), which adds sourcing, tenders and contract management upstream.
How to choose the best Procure-to-Pay software: the 7 criteria
The best P2P software is not the best known, it is the one that fits your organisation. Here are the 7 criteria to check before signing.
- Full cycle coverage : purchase request, order, receipt, invoice and payment in the same tool. A tool limited to invoices leaves everything upstream in Excel.
- Automatic three-way matching : order, receipt and invoice compared automatically, with tolerance thresholds. This is the criterion that saves the most time.
- E-invoicing compliance : receipt of Factur-X, UBL and CII formats via an approved platform.
- Integration with your ERP : retrieval of suppliers, items and entries with no double entry.
- User adoption : catalogues and punch-out, mobile approval, a simple interface for occasional requesters.
- Supplier portal : your suppliers view their orders, invoices and payments, which reduces chasers.
- Total cost and deployment time : subscription, integration, training, and a realistic timeframe before the first gains.
Depending on your sector, add an 8th criterion: multi-site, public procurement or inventory management.
Our method: how we compared Procure-to-Pay software
We assessed each solution against the 7 criteria above, based on information published by the publishers and our knowledge of the procurement market in France. We deliberately chose solutions with different profiles:
- complete P2P suites, covering procurement from request to payment (Oxalys) ;
- Source-to-Pay suites designed for large groups (Coupa, SAP Ariba, Ivalua);
- invoice processing specialists, starting from accounts payable (Basware, Medius, Esker).
The ranking reflects the fit with each company profile, not an absolute score: software that is perfect for an international group may be oversized for a mid-sized company.
Comparison of the best Procure-to-Pay software
Oxalys comes out on top for French mid-sized companies, SMEs and public organisations : it is the only solution in the comparison that is French, modular and focused on the full P2P cycle.

Which Procure-to-Pay software should you choose for your profile?
The size of the company and the starting point of the project determine the right choice.
If your invoices are already automated but your orders still go through e-mail, that is a sign you need real P2P software, not just an invoice processing tool. To find out more, discover how Oxalys Procure-to-Pay software digitalises your procurement and how to handle a non-compliant supplier invoice.
What gains can you expect from Procure-to-Pay software?
Well-deployed P2P software acts on four measurable levers :
- Invoice processing time : only invoices with discrepancies require intervention. At F2J Industry, the time spent processing supplier invoices fell by nearly 40%.
- Spend control : every purchase goes through an approved request, which limits off-policy and off-contract purchasing.
- Financial visibility : commitments known in real time, accruals calculated automatically, faster closings.
- Supplier relationships : fewer disputes, payments on time and a portal that reduces chasers.
The 8 questions to ask during a demo
A standard demo always shows the ideal case. To truly compare Procure-to-Pay software, insist on your own scenarios :
✅ Your question checklist
- Demonstrate an invoice with a price discrepancy : how is it detected, and who is alerted?
- How is a partial receipt handled when it is invoiced in full?
- How do Factur-X, UBL and CII invoices arrive via the approved platform?
- What data is synchronised with my ERP, and in which direction?
- How does an occasional requester place an order from a catalogue?
- Can I change an approval workflow without calling on the publisher?
- What does my supplier see in the portal: orders, invoices, payment status?
- What is the realistic timeframe before the first order is placed in the tool?
The 5 steps to deploy Procure-to-Pay software
- Map your current flows : order and invoice volumes, approval workflows, tools in place.
- Prioritise an initial scope : often purchase requests and orders, where discrepancies arise.
- Connect the ERP and the approved platform : suppliers, items, entries and electronic invoices.
- Train users by profile : requesters, approvers, buyers, accounting.
- Extend module by module : receipt, invoice matching, supplier portal, then sourcing and contracts.

How to choose the best Procure-to-Pay software?💡
What is the best Procure-to-Pay software in France?
For mid-sized companies, SMEs and public organisations, Oxalys is the most complete P2P software : it covers the entire cycle, from purchase request to payment. Large international groups tend to turn to Coupa or SAP Ariba.
What is the difference between Procure-to-Pay and Source-to-Pay?
The Procure-to-Pay covers operational purchasing, from request to payment. Source-to-Pay adds sourcing, tenders and contract management.
How much does Procure-to-Pay software cost?
The price depends on the number of users, modules and integrations. It generally consists of an annual subscription and deployment fees. Request a demo to get a tailored quote.
Is P2P software useful with e-invoicing?
Yes. The approved platform transmits electronic invoices, but only P2P software matches them automatically with orders and receipts before payment. We chose AGENA3000 to handle this connection.
How long does it take to deploy Procure-to-Pay software?
It depends on the scope and the integrations. A module-by-module deployment, starting with purchase requests and orders, delivers the first gains quickly.
What is the best P2P software for an SME?
An SME needs software that is easy to deploy, modular and in its own language, covering purchase requests, orders and invoices without a heavy project. Oxalys meets this need; suites for large groups, such as Coupa or SAP Ariba, are often oversized for an SME.
What is the difference between P2P software and invoice management software?
Invoice management software processes invoices once they are received. P2P software covers the entire upstream cycle : purchase request, approval, order and receipt. This is what allows it to match each invoice with an order and a receipt.
Is there free Procure-to-Pay software?
There is no real free P2P software for businesses. Spreadsheets and basic ERP modules let you get started, but with no approval workflow, no automatic matching and no supplier portal.
