The Zamp Commitment

We stand behind every result — and we make it right if we’re wrong.

Accuracy guarantee.

If you are a Zamp API customer and an inaccurate result returned by the service triggers a state sales tax audit, Zamp will cover any uncollected sales tax, penalties, and interest resulting from the inaccuracy, up to what you paid Zamp over the prior 12 months, provided you:

Proper API setup.

Properly set up and configured the Zamp API at the time the inaccurate result was returned.

Timely audit notification.

Notify us within 15 days of first receiving notice of audit and share your audit-related information so that we can help research the situation.

Cooperation with state authorities.

Allow us to work with the state in case they are wrong, to reduce your liability, and provide reasonable assistance to Zamp in this process.

Filing commitment.

If you use Zamp to file your sales tax returns, we take responsibility for getting them filed on time.

If we are the reason a filing is submitted late, we’ll cover any penalties or interest charged by the state as a result of that delay.

This Assumes

  • You provided complete and accurate information on time.
  • The connected bank account had sufficient funds to pay the return.

You shouldn’t have to chase deadlines. That’s our job.
