What do you like best?
Overall, this is a pretty good product. I use it for inventory management and shipping. When it works, it really works well. Their inventory receiving module is unmatched by anything out there. It is really what keeps me with Monsoon.
What do you dislike?
Over the years (I've been using this product for 9 years now) it hasn't quite kept up with online selling as well as I would like it to. There are features it should be using that it doesn't (like best offer on ebay) and additionally, this should really be cloud based and not PC based. It also hasn't kept up with online trends, such as some sellers offering free shipping and doesn't price against that well, resulting in needing to used fixed pricing which reduces profit and sales.
Recommendations to others considering the product:
It's worth a try. Like I said, the inventory receiving module is unmatched. There are some long term problems (that every company has) that need work arounds to make this work for you.
What problems are you solving with the product? What benefits have you realized?
It overall works for a multi channel sales compay.
