We tried a lot of Amazon stats tools before we finally ended up on MBS, and what a difference and breath of fresh air it is! You can really tell it's built by people who actually sell on Amazon and use the software themselves. The detail and flexibility is fantastic. It's not the cheapest, but is well worth it and you'll be glad you went straight to MBS over others. You can add functionality and expand your access to it's feature set as you need, so it can start off relatively affordable. Plus support is responsive and actually cares. Highly recommended!
MBS had indeed been developed from the start by Amazon sellers, and we continue to look for ways to make it even more useful for that audience. We DO care and I'm glad that shines through. We consider our users family. Your success is ours, and vice versa.
Thanks again for taking the time to leave a review! As you know they really help.
