Built for advisory firmsscaling their tax practice
L3i was founded with a simple mission: to transform how accounting firms handle sales tax compliance. We believe that powerful technology should be accessible, intuitive, and designed to help firms grow.
Our Story
L3i was born from firsthand experience with the challenges of sales tax compliance. Our founders, having worked with hundreds of businesses struggling with audit defense and multi-state compliance, saw an opportunity to revolutionize the industry.
Traditional approaches to sales tax management are manual, error-prone, and don't scale. We knew there had to be a better way. By combining advanced AI, modern cloud infrastructure, and deep tax expertise, we built the platform we wished existed.
