Software Calculates Sales Tax. We Take Responsibility for It.

Avalara, Numeral and Kintsugi are all built around software. It’s good software — it calculates rates and automates parts of the process. But a platform still leaves your team to configure it, review what it files, answer state notices, watch for new nexus, and handle an audit if one lands. For a multi-state business, that work doesn’t disappear — it just moves to your desk.

Sales Tax Solutions is a managed service, not a dashboard. We’ve run sales tax compliance for businesses since 2005. Real specialists own your registrations, filings, notices, nexus, and audit defense end to end — and we work alongside whatever tools you already use rather than forcing a rip-and-replace.

How we compare

Comparison reflects general positioning; features and plans vary by provider. Avalara, Numeral and Kintsugi are trademarks of their respective owners.

When a managed service is the better fit

If you sell into many states, if sales tax eats hours of your finance team’s month, if you’ve had a notice you weren’t sure how to answer, or if you’re worried about past exposure — software alone won’t fix that. A team will. You get dedicated specialists, one point of accountability, and audit-ready records, instead of another platform to run.
