Zamp for Developers

Loved by Founders, CFOs, and Operators

Zamp customers never have to touch sales tax again

Sandro Roco

CEO of Sanzo

Since making the decision to partner with Zamp, my sales tax headache has gone away!

They helped us determine what states we needed to collect in and then handled everything from there. They’ve made it a super easy process for us!

Madeline Zephyr

Founder & CEO

I want to think about sales tax as little as possible -- it’s a complicated and time consuming, and every minute spent jumping through hoops is a minute I’m not spending making an impact on the future of kids’ health.

After switching to Zamp, I rarely have to think about it! I am confident in their team’s ability and love the accessibility their team provides when needed.

Chad Held

Co-Owner

Zamp has been the best in-house team member that is actually a partner. They have been so easy to work with and have lifted every piece of sales tax filing off our hands.

The team answers any questions you have in what seems like minutes. Have been very happy with the onboarding and filing process so far!

Allen Shafer

Co-Founder

We want our team’s full focus on creativity and growing the business. Not sales tax and the latest notices from 15 different states.

Zamp’s managed solution is unique as they really do it all. Moving over to Zamp from our previous provider was a no-brainer.

Kate Savage

Digital Marketing Manager

I provided Zamp with my existing registration information and they set everything up for me.

My advice to other businesses is to get started with Zamp right away.

Andy Nalla

CEO of Ghost Golf

Their team made sure we weren’t double remitting taxes that the social platform already collected.

I trust them to keep our business compliant. And if anything ever comes up, I know they are just a phone call away.

Ana Padilla

COO of Yumwoof

Our mission at Yumwoof is to help take the stress out of finding the right food for our customers' dogs so they can live healthier.

Zamp has allowed us to offload our sales tax requirements so we can live healthier. It's the perfect
partnership!

Jay Reale

Owner

Their pricing was all-inclusive, and after the setup, which was fairly simple, they would take it from there, easing my mind that I wouldn’t have any more nightmares about attempting to do our own sales tax returns or having to remember the deadlines to avoid penalties. So far, Zamp for the win!

Amy Dalley

Co-Founder of Amped

At Amped Bikes, our passion is motorsports. We operate in a lean, high-growth environment.
