Think of an invoice as something you give to customers when you make, provide or sell them something that isn’t already on your (physical or digital) shelves. In other words, invoices are ideal for larger orders, custom orders and/or to request a payment at a later time. Let’s return to our florist example.

The invoice meets the checklist criteria mentioned above as set out by SARS and the VAT act. Invoices sent in encrypted form must be in at least 128-bit encryption format.

A service invoice is an accounting document that a service-based business sends to its clients to request payment for its services. Service invoices provide the client with the amount owing on the invoice, the deadline for payment, and a detailed list of the services provided.
