Customer and Vendors to be linked for the scenario where sales invoice can be raised to a vendor or purchase needs to be booked from a customer. Scenario is that vendors are allowed to work in the organization premises and other income is charged from them against this facility and the same is adjusted with their outstanding.

Currently a new customer is required to be created and then only sales invoice/free text invoice can be posted. Even invoice journal won't work as GST receivable will be booked in this case whereas in the above mentioned scenario GST payable is required to be posted.

There should be a functionality to book the sales invoice to vendor.
