What really sets Zamp apart is their team. They’re consistently there when we need support, they genuinely listen, and they follow through on what they say they’ll do. Sales tax is complicated and always changing, so having experts in our corner, people we can trust, makes a huge difference.

Their QuickBooks integration is the other major win for us. Tax is calculated directly on our invoices, and our transactions sync to Zamp automatically for filing. That gives us confidence that our sales tax is being handled accurately and that nothing is slipping through the cracks.

Another unexpected bonus has been how responsive they are to feedback. When we’ve raised a need, they’ve listened and acted on it, which isn’t something you always get from a software company. Review collected by and hosted on G2.com.

One hiccup we ran into early on: we create invoices 60 days in advance, and sales tax was pulling into the earlier period instead of the period the invoice actually applied to. That created extra cleanup on our end. Zamp listened, understood the impact, and implemented a fix. The way they handled it is a good example of why we trust their team.

The team’s speed and attention to detail are unmatched. Follow-ups come at the right cadence, so I trust nothing is slipping through the cracks, even when they’re waiting on something from me. The automated emails are actually relevant, not noise, and whenever I reply to one I get a capable human right away. Review collected by and hosted on G2.com.

Honestly, not much. The one area I’d love to see more is a tighter loop on state notices. When we get mail from a tax agency, it would be great to have a simple way to share it with Zamp and see it tracked alongside everything else they’re handling, so we know it’s covered. Small thing in an otherwise seamless experience. Review collected by and hosted on G2.com.

I have tried a lot of tax software and all of them have support offshore and are very difficult to communicate with. Zamp's support has been excellent in the USA and people actually care about your business with no language barrier! Review collected by and hosted on G2.com.

There is not much to be unhappy with but no one likes the cost, but so far they have been excellent for me. I hate dealing with sales tax, I like to run my business not deal with accounting and Taxes. I can trust Zamp unlike others I have tried like Avalara and Tax Cloud, where there's little to no communication and Avalara did not even have someone assigned to my account for 6 months before I realized things were not being filed correctly and ended up costing me a fortune, worse yet try cancelling with Avalara! Good Luck! Review collected by and hosted on G2.com.

What I appreciate most is the automation and the level of managed service that ensures everything is being taken care of. We run a fast-growing e-commerce business, so we need to stay compliant and collect sales tax correctly without putting a heavy burden on our internal team. Put simply, Zamp takes care of this.

Honestly, I have no complaints. They get the job done with an easy-to-manage UI and solid service. It feels like they’re there to make sure everything runs smoothly in the background while I focus on running my company. Review collected by and hosted on G2.com.

I like that Zamp makes it easy and hassle-free to take care of each state's tax filing needs. Authorizing the monthly tax filing for each state is straightforward and without any problems. I've had a wonderful experience with Suzanne and the US tax-filing service. It's smooth, organized, and truly customer-focused. Whenever I have a question, the team responds quickly and provides great customer care, handling every part of the US tax filing process thoroughly. This thoroughness makes me feel completely at ease. The initial setup of Zamp was also very easy. Review collected by and hosted on G2.com.

Maybe they could look into also servicing state tax. Review collected by and hosted on G2.com.

The best thing about Zamp is the personal expertise and assistance they provide. They are a true partner and have been extremely helpful in every aspect, from the logistical aspect of setting up state returns to problem-solving more complex technical issues specific to our business. Their tools are easy to use and straightforward. They are proactive about identifying actions we need to take and are willing to do all of the leg work. It is a night and day difference compared to other large legacy sales tax solutions we were previously using! Review collected by and hosted on G2.com.

For a business of our size, it is a significant monthly cost (though very reasonable relative to competitors) Review collected by and hosted on G2.com.

How easy they make my life. The process is so seamless and it's completely off my mind knowing they take care of this for me. Review collected by and hosted on G2.com.

Nothing. Their team is amazing, the platform is easy to use, so 10/10 Review collected by and hosted on G2.com.

Any time there’s an issue, they respond quickly. They also got us registered promptly in the states where we wanted to track, and they’re consistently timely when submitting state taxes. They even worked with our development team while we were updating our website, after they noticed we had temporarily stopped collecting taxes. Review collected by and hosted on G2.com.

The upfront payment for set up was quite a big nut to swallow. They should offer the ability for monthly payments over the course of a year. Review collected by and hosted on G2.com.

Communication with Zamp has been excellent. Whenever we’ve run into tax issues with state filings, their team has handled them promptly. Review collected by and hosted on G2.com.

I don’t have any dislikes in particular. The pricing model scales with the business, so there are no surprises as the business grows. Review collected by and hosted on G2.com.

Sales tax compliance is easy now! They've taken a lot of work off our plate. Review collected by and hosted on G2.com.

Cost - while we get good value for the money (lots of time/administrative burden avoided), it is still expensive. Review collected by and hosted on G2.com.
