I have a problem about services. The thing is that in Navision there’s warehouse module and that’s for selling the goods. But what if a company doesn’t sell goods but only services. What in that case? Could you enter information about a service in an article card? But what about negative inventory that comes up in that case?
Sell “Resources” instead of “Items” (or “Articles”). The system will keep track of how many you sell and you don’t have to worry about negative quantities. Best of luck, Mark.
