All of it runs natively inside SAP ECC and S/4HANA without requiring custom development or modifications to SAP's core code.

What sets Doxis apart is the depth of its SAP integration. Your procurement team works directly in SAP with their existing workflows, while Doxis handles the document capture, AI extraction, and automated matching in the background.  

The AI models come pre-trained for common procurement documents, which means you get high accuracy from day one.

Not every solution labeled "SAP-compatible" delivers the same depth of integration. Before comparing vendors, knowing what separates the strong options from the generic ones saves you time.

Native SAP Integration

The software should work directly inside SAP ECC or S/4HANA, not via middleware or CSV exports. Without this, your team ends up managing two systems and reconciling data manually.

End-to-End P2P Coverage

Look for a solution that handles the full cycle from requisition to invoice, not just one slice of it. Point solutions solve one problem but create handoff gaps elsewhere in the process.

AI-Powered Document Processing

The software should automatically capture, classify, and validate POs, order confirmations, and delivery notes. Manual data entry at any stage of the process reintroduces the errors and delays you are trying to eliminate.

Automated 3-Way Matching

Your solution should match POs, goods receipts, and invoices without manual intervention. Automated matching is one of the highest-impact steps in reducing AP workload and preventing overpayments.

Configurable Approval Workflows

Look for routing that works based on your business rules, not fixed templates. Exceptions and multi-level approvals behave differently in every organization, and the software needs to reflect that.

Audit Trail and Compliance

Full document history is non-negotiable for internal controls, regulatory requirements, and eInvoicing mandates. This is especially important for global businesses operating across multiple jurisdictions.

Scalability

The software should handle volume spikes and multi-entity or multi-country rollouts without performance issues. What works at 10,000 POs per year needs to hold up at ten times that volume.

Most PO automation solutions in this list address one or two parts of the procurement process well, typically invoice processing or AP approvals.  

Doxis is the only solution that covers the complete purchase-to-pay process inside SAP as a unified bundle: purchase requisitions, PO generation via electronic order dispatch, order confirmation matching, delivery, invoice, and archiving, all without switching systems or requiring custom SAP development.

Where competitors like Coupa or Basware operate alongside SAP as external platforms, requiring ongoing integration work to keep data consistent, Doxis runs natively inside your SAP environment.  

Your team works in SAP as they always have. Doxis handles the automation layer transparently in the background.

For businesses already planning or executing a migration to SAP S/4HANA, Doxis's modular approach lets you automate specific process steps without committing to a full overhaul, and scale across the full P2P bundle when ready.

If your procurement team is losing time to manual PO processing, data re-entry, and approval chasing, the cost is showing up in your cycle times, your supplier relationships, and your AP overhead.

Doxis P2P for SAP gives you a complete, AI-powered automation layer that works inside your existing SAP environment from day one. With Doxis, you get:

• End-to-end P2P automation, from requisition to archiving, in a single SAP-native platform
• Pre-trained AI models that deliver high accuracy on invoices, POs, order confirmations, and delivery notes
• Up to 80% reduction in invoice processing effort
• Up to 24% cut in procurement costs through automated compliance and maverick buying controls

• Full audit trail and eInvoicing compliance for global operations
• Recognition as a Leader in the Gartner® Magic Quadrant™ for Document Management 2026
