Approval workflow control	80The product includes approval processing and rule-based approval workflows; buyers should validate the routing and control details needed for their own policies.	82Approval routing, configurable controls, role-based access, and approval history support controlled invoice review; buyers should confirm how their own delegation and escalation rules are configured.
Coding and matching accuracy	76Multi-way matching and rule-based matching algorithms support purchase-related invoice processing, while the supplied facts do not specify coding-field coverage or matching behavior for each buyer configuration.	75ERP-context coding suggestions and semi-automated two- or three-way PO matching support coding and matching, while full Billy automation depends on agreed scope and ERP configuration; confirm field coverage and exception handling for the selected setup.
Invoice capture quality	84Medius lists Medius Capture in both AP packages and describes invoice capture within its AP workflow; confirm the required document fields and extraction scope for your invoices.	78Invoice capture includes duplicate detection and ERP-context coding suggestions, giving AP staff signals to review during processing; buyers should validate capture accuracy and document handling for their invoice mix.

Vendor payment management	58Medius Payments is available as an additional-cost application, so payment execution needs separate package and fee confirmation rather than being assumed in the base AP quote.	54Direct Pay provides a distinct vendor-payment workflow with its own fee arrangements, but the core AP offer does not establish payment execution as included; buyers should scope payment methods, remittance, and status visibility separately.
AP exception visibility	74AP reporting and invoice-processing visibility support operational monitoring, while the supplied facts do not detail specific aging, bottleneck or exception-report functions.	76Duplicate flags, invoice audit history, reports, and dashboards give teams several ways to review processing activity; buyers should verify how matching failures, missing information, and aging unpaid items appear in their configured workflow.
