What happens if I get a notice from a state?

You send it to us, and we handle it. Both of our service models include end-to-end notice management, where we communicate with the tax authorities and resolve the issue on your behalf. There’s a good chance we will resolve the notice before you get a notification.

What does "rooftop-accurate" actually mean?

It means we determine sales tax based on the precise building address of your customer using geospatial coordinates, not just a general ZIP code. This is the highest level of accuracy available and protects you from over or under-collecting tax.

How easy is it to switch to Zamp?

Our white-glove onboarding makes switching painless. A dedicated specialist will handle your data migration, account setup, and any existing state registrations to ensure a seamless transition from day one.

How is Zamp different from tools like Avalara or TaxJar?

Most tools are “Do-It-Yourself,” meaning you are still responsible for setup, monitoring, and troubleshooting. Zamp is a “Done-For-You” service. We combine our powerful technology with a dedicated team of experts to manage the entire process for you, providing both a platform and a partner.

Who is Zamp best for?

Zamp is designed for growing small-to-mid-size digital businesses (e-commerce, SaaS, digital services) that need a reliable, expert-led solution for their increasingly complex sales tax obligations.
