Why Finance Leaders & Founders Choose Zamp

Growing businesses partner with Zamp because we remove the entire sales tax burden, not just pieces of it, letting you focus on what truly matters—scaling your business.

Sam Bauman

Director of Finance, David

If you’re planning on selling nationwide and growing pretty quickly, then the filings that you’ll have to do with the states could ramp up quite fast.

Knowing that you have a trusted partner that will respond efficiently and quickly is really valuable. I couldn’t recommend Zamp highly enough to be that trusted partner for you.

Mayra Jimenez

Assistant Controller, Kombo Ventures

I'm no longer spending multiple hours in a month trying to reconcile large amounts of data for Shopify and wholesale and retail.

Having Zamp being able to manage the transactions has been really helpful. We have a lot more time to really dig into our own trends and day-to-day tasks.

Kelly Tuohey

Corporate Accounting Manager, Left On Friday

Sales tax is totally not worth it to do it yourself. It's such a lifesaver to have a company fully manage your sales tax obligations for you.

Definitely reach out and have a chat, because you guys are so friendly and knowledgeable.

Paige Honeycomb

Chief of Staff, Puzzle

Taxes are scary for any business. Nobody wants to get dinged for a stupid reason just because they're misinformed.

Zamp’s team has the ability to be there and support companies as they go through those scaling and pivotal revenue-generating moments of their company.

Allen Shafer

Co-Founder, Fulton & Roark

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.

Sandro Roco

CEO, 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!

Andy Nalla

CEO, 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.

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!
