Zero cost purchases

Good afternoon,

I have an invoice for a purchase which was paid by using a voucher. As a result the overall total was 0 pounds. I however still have to, for auditing purposes, enter it onto the system.

How do I do this? When I generate a purchase for zero balance the system does not allow me to save it.

Best regards,


You can generate invoice then credit note
Or leave it as it has no monetary value

Who owned voucher if you then it would be owner paid for purchase

Its for an IT exam. I paid initially with my credit card and used a discount voucher supplied by Microsoft. This voucher also entitles me to a free retake. You therefore get a second invoice for the second attempt at zero balance.

I suppose that in this case I could upload both invoices as attachments to the payment for the first payment. I’l do this.
