BSS B2B Wholesale Solution

I have had the app installed for a few months. It is full of features but it is also unreliable and has a fair share of bugs. The pricing has failed MULTIPLE times and charged customers full price instead of the discounted rate. Previously (not in the past 2 months) the "servers" have also failed and caused customers to see and be charged full pricing. Now today I have added new products to custom pricing lists and the discounts are not working. It's really fustrating to pay $50/m for an app that is not reliable.
