BusinessMind does not have a model import! This being said when importing skus into BusinessMind Models are created for those skus.
This means you can utilize the sku import to get models into your system. BUT as you may have noticed the sku import can not import skus at zero qty. So the question is how can i work around this if I am only interested in importing models?
Our suggestion would be to use the sku import tool to create these models. After this you can use the batch manage qty tool to change the qty of the imported skus to zero.
These two articles will guide you on importing skus into businessmind and guide you on the batch qty change process
