Hello Community Users! We just thought we'd add an update to this thread. If you do business as a customer and a supplier with the same company and need to offset an invoice against a purchase invoice this is usually done by creating a contra entry. The best way to show this as a contra is with a journal. We have included an article here on what the journal would need to look like. Then you use the journal against the invoice and purchase invoice as payment or part payment. Any questions feel free to just ask.
