Fabrikatör Inventory Planner

This is a great app if you're having trouble figuring out when to buy stock! I kept running out of product and was having a lot of stop and gos. The support on this app is very helpful, they have a demo call with you, and are available via chat to help with anything else that comes up. They also have Loom videos that show step by step have to implement areas. It's a pretty easy to use app and worth the $.
