Kraftology review for Sumtracker Inventory Manager

Brilliant inventory and bundling solution!!! I sell customised gift products and have various raw materials and finished goods to account for with many to one or one to many structures. Only sumtracker is able to provide an easy-to-use, practical inventory system which can go live the moment I start the subscription. Help support is also very prompt whenever I have any questions. I've been searching for ideal inventory system for a long time and found that Sumtracker is the best solution I've found so far.
