Case Study: a big four company modernizes tax and legal entity management with Brainhub

Big Four Company builds 3 applications in 4+ years with Brainhub

A Big Four company faced significant challenges after two previous software agencies failed to develop a stable and secure financial application for tax reporting and legal entity management. After two years of rising costs and no working product, the consulting leader turned to Brainhub for its recognized expertise in software modernization and React development.

Brainhub successfully developed three complex applications: a tax calculation tool, a master data management system, and a state tax aggregation system. Using a tech stack including Node.js, React, TypeScript, and AWS, Brainhub delivered the first product in just 12 months, earning the client's trust and leading to a four-year partnership. The solutions modernized legacy systems, automated complex processes, and ensured high security, ultimately transferring all knowledge to the client's in-house team after the successful engagement.
