Shopify and manufacturing inventory platform

[Biltong-great]

Our business is in manufacturing and selling online. We have integrated Shopify and Katana, which manages the inventory from manufacturing to shipping.

Product inventory in Katana is not reflecting in Shopify and we therefore cannot sell. The support staff and engineers have been trying to resolve this for three days now.

Katana is costing us $129 per month and it is frustrating. 

I'm looking for suggestions for an affordable inventory system that is working well.

I use MRPEasy and I've been very happy with the Shopify integration.   The only thing it doesn't do, which I wish it would, is show the virtual inventory (I physically stock things in component form and assemble the kits as they are ordered).   I can see virtual inventory in MRPEasy, but that doesn't integrate with Shopify, so that makes it a bit challenging.
