Case Study: Avalara achieves faster, more reliable global tax processing with MongoDB Atlas

Avalara reduces tax call latency by 70% with MongoDB

Avalara, a global tax compliance software company, faced challenges scaling its legacy SQL systems. This single-cloud architecture limited growth, increased latency, and risked customer experience as transaction volumes grew. To modernize, Avalara turned to MongoDB, specifically migrating to the MongoDB Atlas platform.

The solution involved a complete rearchitecture named Project Polaris, moving billions of documents to MongoDB Atlas on a multi-cloud foundation. This provided a flexible data layer for microservices. Using MongoDB resulted in tax call latency dropping from 500ms to under 150ms and achieving 99.99% uptime. Avalara also reduced costs and accelerated development, positioning the company for global expansion.
