# What is Zamp?

> Zamp is a fully managed sales tax solution — intelligent software plus a team of experts that handles registration, calculation, filing, and remittance end to end.

Sales tax is one of the most complex, highest-risk parts of running a business — and it only gets harder as you grow into new states and countries. **Zamp is the last sales tax service you'll ever need:** an intelligent sales tax platform with a managed service built in, so compliance happens quietly in the background.

<Note>
  **When tax becomes simple, everything else accelerates.** Zamp pairs best-in-class software with a team of sales tax experts to take compliance off your plate completely.

## Get sales tax off your plate

Most tools hand you software and leave the hard part to you. Zamp is different — it's a **fully managed, done-for-you** service that owns the entire sales tax lifecycle so your team doesn't have to.
