A U.S.-based specialty manufacturer serving defense, aerospace, and energy markets faced a complex use tax compliance challenge following a Colorado state audit. Their manual, spreadsheet-based approach to accounts payable tax calculation required significant time, was prone to errors, and left the company vulnerable to penalties. To future-proof compliance and improve accuracy, the manufacturer selected Sovos OptiTax, an ERP-agnostic, automated solution for AP tax calculation. The implementation provided immediate visibility, audit-ready reporting, and the ability to self-audit with confidence.
