What our customers say

Trusted by 100’s of small, medium and large accounting firms and advisors

Highly recommend for Amazon eCommerce retailers

Tax calculation should be a simple job for an accountant, yet we used to pay ridiculous money for something that is fairly straightforward. Now with SalesVAT, I spend just one fifth of what I used to pay, but I feel much better organised. Highly recommend SalesVAT for Amazon eCommerce retailers.

Can’t imagine my business without it

We have recently expanded from just Amazon into eBay and Shopify. I dreaded about how I was going to pull all the sales data together and calculate the VAT. SalesVAT made my VAT calculation and filing really simple and I did not even have to use a VAT consultant. Couldn’t be more happier.
