A global professional services company specializing in audit, tax, and consulting wanted to transform a legacy indirect tax application to better serve clients.
The existing application incorporated heterogeneous technologies and lacked the scalability to manage a huge volume of tax-related data.
Infosys migrated the on-premise application to Microsoft Azure cloud leveraging Azure’s PaaS.
The company faced several challenges with its legacy application while processing indirect tax data:
Key Challenges
Incurred escalating IT infrastructure costs
Paid recurring license fees for multiple software products
