Log payment for a purchase from a sales invoice

[JHP]

Hi, I have raised an invoice for a supplier, we currently then ended up buying products off him a week later so he then billed us minus what he owed us, can I log payment for the sales invoice against the purchase invoice so then just the balance is outstanding as no money changed hands for the amount of our sales invoice?

Hi JHP,
you could use/create a dummy bank account in which you write in all the money from the purchases and sales invoices to/from this particular company, and tag the virtual transferred money to the sales/purchases invoices.
