Looking for a plugin to manage locations and invemtory

Hi,

I am looking for a plugin that has a good start or a fully completed plugin that allows someone to log in on the front end, Have a list of their locations for their storse (brick and mortar) and allow them to update their current on-hand inventory for each location once a month. On the backend I’d be able to export by date rate into csv/excel.

If there is something out there that might even be a good start I can take it the rest of the way. If there’s nothing where’s a good place to start when looking at exposing the data entry to the frontend with custom roles?

Thanks!
