About L3i
The story behind
L3i.
We were founded with a simple mission: transform how accounting firms handle sales-tax compliance. Powerful technology should be accessible, intuitive, and designed for the way modern practices grow.
Our Story
Born from firsthand experience.
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 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.
“Helping firms triple their client capacity while reducing audit risk.”
