Was really reluctant initially to reach out due to past bad experiences with a different online accounting company. Come to realize that Amz Accountant is the best thing I could have done for my business! Not only did Gabriel help to amend my previous years taxes but also helped to get me on the right track for the coming year. Communication is always expedient, easy to understand, and the follow through is always on point. Everything is reasonably priced for the level of service they provide. They take the stress of taxes off your plate so you can focus on running your business. Would highly recommend to anyone who does ecommerce business!

I just want to thank Gabe and Imran for everything they do!! They helped my business recover unnecessary sales tax charges that I shouldn’t have paid. They worked very closely with me to help structure my books and create organization for my business so that I can get a clear idea about my cashflows and PnL. Would 100% recommend their services to anyone!

This is the second year in the row I have used Gabe's services. He is very knowledgeable, and he works diligently to ensure your business has the best outcome. He is very patient and detailed when explaining concepts and processes that are very foreign to the average person. Having him handle both my business and personal taxes relieved such a major burden. I am confident in his quality of work and he comes highly recommended!

As an overseas seller trying to break into the US market the world of American Sales Tax can be daunting and confusing. After receiving a lot of conflicting advice prior to finding AMZ Accountant, Gabriel explained what we should do and why, and helped us understand the intricate American tax system. We would recommend AMZ Accountant to everyone - and we're looking forward to the ongoing partnership between us both.

Amz Accountantants are absolutely amazing. I worked with Imran directly, although I reached out near the end of the tax season and he warned me of his busy schedule. He was still able to guide me with the best advice, and file my return timely. Highly recommend, will continue my business
