We are in trading business. We have a customer/supplier from whom we purchases as well as sell our product. So I am confuse whether to use one head or 2 different head for the same company..The issue is if I make 1 head as Account Payable and we sell more good than we had purchased, this will cause Account Payable to be negetive.Can we have Negetive Account Payable?
      Answer1:Treat this customer as if he were two completely different customers. Create an account for him in Receivables, and another account in Payables.
      Answer2:creating two different account wil be a proper accounting procedure
