What is an invoice?

An invoice is a list of goods sent or services provided, with information about the sum due for these. You could also call it a bill or a tally, though it's a little more involved than a simple receipt.

A good invoice must include the following pieces of information:

  • Your business name and address
  • The name and address of the company or customer you are invoicing
  • A unique invoice reference or number that can only refer to the invoice in question
  • A date - usually the date the invoice was created (raised, for the accountants in the audience)
  • A list of the products and/or services you have provided, liny by line, with a cost for each
  • A total amount for the invoice
  • The payment terms (e.g. how long a customer has to pay)

It's also a good idea to include:

  • The amount of VAT/IVA/GST for each item or the total tax amount for the whole invoice, if every item is subject to the same rate
  • Your VAT number (if you are VAT registered)
  • Your company number (if you are a registered company)
