Hi! Ask me about anything you can buy or sell..

Get sales tax right..

U.S. corporations overpay $30B in sales tax each year on purchases that are actually tax exempt, and get only 65% of it back with a reverse audit. applies machine learning technology to prevent these overpayments from happening in the first place.

Sales & use tax compliance is tough.

This is what we hear over and over from our customers. Here's why:

Too many purchases

Companies purchase thousands of things every day: making it impossible to review, even for a team of tax experts.

Too many rules

State tax codes can get pretty complicated, especially if you have operations in multiple jurisdictions.

Complicated systems

Accruing use tax, applying exemption certificates and filing refund claims all require knowledge of many complicated systems.

Our AI-powered platform corrects past errors and prevents them from being made in the future. It's sales & use tax compliance with minimal effort.

We train our AI on your data

We build predictive models tailored to your purchasing and use of items and services. This is done on a per-location basis, so our system can apply the right tax rate and State tax exemption laws. Here's the data we need:

Accounts Payable data

An excel or csv file with purchases your company has made in the last four years. This is a report you can run in your ERP (or ask IT to run it for you!).


PDF files of invoices from the purchases made. Usually, these are stored on a network drive or directly in your ERP.
