Medius Integrates Thomson Reuters ONESOURCE for Pre-Payment Tax Checks
Jacksonville, Fla. – September 14, 2026 -- Medius has integrated Thomson Reuters ONESOURCE indirect tax determination into its AP Automation platform, allowing businesses to verify US sales and use tax on every invoice before it posts to the ERP.
Tax verification now runs inside the approval workflow before payment
As invoices move through Medius AP Automation, vendor-charged US sales and use tax is recalculated against the Thomson Reuters ONESOURCE determination engine, checking each line item jurisdiction by jurisdiction. Overcharges and undercharges are automatically flagged before payment, addressing risks for finance teams operating across thousands of US tax jurisdictions.
