A little about us.

We’ve been know as the most Advanced FBA calculator on the market but to be honest FBAmultitool is so much more. As far as we know the features you’ll find on our app are like no other, we’ve been working on this since 2017 and managed to launch start of 2018. The first of our kind.


The supports been great we can’t thank you enough.

We’re working on this app every month, updates & fixes come out very regularly, this isn’t some app we’re going to finish building and leave alone.

We will continue to grow and listen to any of your suggestions. We take all ideas on board, If you have any please do send them over and we can discuss with you more about it and how we can implement it.


This entire app was built around what Amazon sellers want and we will continue to work that way.

Any questions or suggestions please do contact us.

Blown away! I already had everything covered apart from “Hazmat”, so thought I’d give it a try. So glad I did. This extension is way better than others and it has already saved me from making a costly Hazmat error.

I was reading reviews on another extension they were saying how the support was charging them to make changes and fixes. So glad this extension has a nice team behind. Keep up the great work.
