A client is a supplier as well

I have a client who’s a supplier as well.

Many times I need to calculate the difference of what I owe to him with what he owes to me.
I.e. I have a sales invoice for him 100euro but I owe him 40euro. Is there a way to have a client and a supplier account to be the same?


If you read the following Guide it describes the process involved

Many thanks for your help.
I search for it before I open the topic but obviously not enough :slight_smile:
