Import Inventory Template for Consigners

[YFNCT]

Greetings!

I operate a retail shop and would like to supply consigners with an inventory template that they could fill in themselves and I could import to Shopify.

I know that you are able to import an inventory list but I suspect the existing Shopify CVS file (https://help.shopify.com/en/manual/products/inventory/inventory-csv), with its many columns, would be daunting for my consigners. Is anyone aware of an existing template that simplifies the columns while still allowing for a smooth upload? A template that "hides" columns that are not in use?  

Totally willing to take this on myself, just curious if it already exists. 

Any assistance is appreciated.
