Very quick support, easy to navigate, responsiveness of onboarding and account managers, easy API integration. We previously used managed services for sales and use tax compliance, and with Zamp we literraly cut the time spend for the preparation of returns in half. Pricing is also very adequate in terms of how much time we save now with Zamp.

Zamp is responsive whenever we have questions about state sales tax issues. They support us with sales tax reporting, and their deliverables are consistently punctual and handled with expertise.

The customer service is phenomenal!! Caroline Cassell is extremely responsive, knowledgeable, patient, and professional. Before acquiring ZAMP services, I was apprehensive about our taxes and realized I needed a professional to assist me. In the few months I have worked with ZAMP and Caroline, my concerns have been eased and I am much more confident in our filings, etc. I am very impressed with ZAMP's tax knowledge and expertise, and I am very grateful they can simplify it for those of us who are less proficient. I am delighted to be working with ZAMP!!
