What Features Should Businesses Compare?
Choosing an AP automation platform requires looking at the complete invoice-to-payment workflow rather than only invoice scanning.
- Invoice capture: Check whether the system can automatically capture invoice data from emails, uploads, portals, and other sources.
- Data extraction: Evaluate how accurately the platform extracts supplier details, invoice numbers, dates, amounts, taxes, line items, and accounting information.
- Invoice coding: Look for automated GL coding, cost centers, departments, projects, and other accounting classifications.
- Approval workflows: Check whether invoices can automatically reach the correct approver based on amount, supplier, department, entity, or other rules.
- Purchase order matching: Businesses using POs should evaluate two-way and three-way matching capabilities.
- Exception management: The system should make it easy to identify and resolve mismatched invoices, missing information, duplicate invoices, and approval issues.
- Duplicate detection: Check whether the platform can identify potential duplicate invoices before payment.
- Supplier management: Evaluate supplier onboarding, payment information, tax documentation, validation, and communication.
- Payment automation: Compare ACH, bank transfers, cards, checks, international payments, and other supported payment methods.
- Global payments: Businesses with international suppliers should check currency, country coverage, tax requirements, and payment options.
- ERP integration: Strong connections with SAP, Oracle, NetSuite, Microsoft Dynamics, Sage, QuickBooks, and other accounting systems can reduce manual data entry.
- Reconciliation: Check how easily approved invoices and payments synchronize with the accounting or ERP system.
- Audit trails: Every invoice, approval, modification, and payment should have a clear history for financial control and audits.

- Implementation and support: Consider migration, ERP integration, configuration, supplier onboarding, training, and ongoing technical support.
- Total cost: Compare software fees, payment costs, implementation, integrations, support, customization, and other ongoing expenses.
How Should Teams Evaluate AP Automation Software?
A practical evaluation should use actual invoices and real approval processes instead of relying only on product demonstrations.
Ask shortlisted providers to demonstrate how their platform handles:
- Receiving an invoice from a supplier.
- Extracting invoice and line-item information.
- Automatically assigning accounting codes.
- Routing the invoice to the correct approver.
- Matching the invoice with a purchase order and receipt.
- Identifying duplicate or incorrect invoices.
- Resolving invoice exceptions.
- Approving and scheduling supplier payments.
- Synchronizing transactions with the accounting or ERP system.
- Producing audit reports and AP performance information.
Teams should also test unusual invoices, missing purchase orders, partial receipts, duplicate invoices, tax differences, supplier banking changes, and invoices that require multiple approvals.
