FORT LAUDERDALE, Fla., Sept. 24, 2026 /CourierPR/ -- Medius, a leading provider of accounts payable automation and spend management solutions, has announced an integration with Avalara AvaTax, a service for indirect tax determination. This integration allows businesses to verify US sales and use tax on every invoice within the approval workflow, before it is posted to the enterprise resource planning (ERP) system.
The integration works by recalculating vendor-charged US sales and use tax against Avalara's determination service as invoices move through the Medius workflow. Any overcharges or undercharges are automatically flagged before payment. This ensures that businesses can maintain accurate tax records and avoid potential liabilities.
For finance teams operating across thousands of US tax jurisdictions, ensuring the correct tax is applied to every invoice can be challenging. Incorrect vendor-charged tax can lead to businesses paying tax they do not owe, while missed use-tax obligations can create unexpected liabilities and increase audit exposure. With the integration, each invoice is verified line by line and jurisdiction by jurisdiction as it moves through Medius AP Automation.
The Avalara AvaTax integration is the latest example of Medius' financial compliance extensibility. The company is committed to developing connectivity to the critical systems that customers know and trust directly into their existing AP workflow, allowing finance teams to maintain their infrastructure without taking on a separate integration project.
Medius and Avalara share 250+ mutual customers today. For those businesses, the integration introduces no new platform and no change to how tax is determined, only to when verification happens in the invoice lifecycle. The approach is focused on customer optionality; businesses can adopt Medius without changing tax engines and continue using Avalara without limiting their choice of AP automation platform.
The Medius team will be exhibiting at Avalara CRUSH 2026 in Fort Lauderdale through September 24. The team is meeting with finance, tax, and IT leaders to demonstrate how tax verification works within the AP approval workflow, including exception handling and activation for existing Avalara deployments.
