Case Study: an oil rig service supplier reduces tax overpayments and automates workflows with Grant Thornton and Vertex

Oil Rig Service Supplier cuts tax workflow time by 40-50% with Grant Thornton LLP

The customer, an oil rig service supplier, faced an urgent challenge following a corporate spinoff. It needed to quickly establish a new tax function and transition to its own JD Edwards ERP system to avoid substantial fees, all while dealing with a legacy tax infrastructure that caused significant errors and vendor overpayments. Grant Thornton LLP was engaged to implement a new tax technology solution, specifically the Vertex tax engine.

Grant Thornton LLP implemented and heavily customized the Vertex software to integrate with the JD Edwards ERP, addressing the client's complex operational needs. The solution automated workflows, which reduced the monthly hours required to manage them by 40-50% and cut vendor tax overpayments by over 80%. The project was completed on time, allowing the company to avoid legacy ERP fees and significantly reduce its audit risk.
