When issuing invoices with InvoiceOnline.com, the user can choose from several types. One of them is the proforma invoice.
A proforma invoice is not a tax or accounting document. Most often the proforma invoice is sent by the supplier to the contracting authority before the actual accounting document. It serves, for example, as a quotation for the customer, a basis for payment of a deposit, etc.
The whole process is very simple, it is enough to have the basic data (ID number) of the customer and the supplier.
