Big-firm experience.
Personal attention.
A focused consulting practice built around a simple idea — businesses should have access to experienced indirect tax and transaction data expertise without the cost, complexity, and bureaucracy of a large consulting organization.
We provide hands-on support for the data, reconciliations, validation, and tax processes that keep businesses accurate, organized, and compliant.
Data reconciliation and sales tax management can become a significant expense for your business. It doesn't have to.
Big-firm experience. Personal attention.
Created around a simple idea.
Our focus is specialized by design. We work at the intersection of U.S. indirect tax and high-volume transaction data, helping businesses address the operational challenges that come with both.
That allows us to go deeper into the details that matter — from transaction data and tax calculations to reconciliations, reporting, refunds and tax technology.
Narrow by design. Deep where it matters.
You need someone who understands your business, your data, and what happens between the transaction and the tax return.
