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)

That sounds like a lot of hassle, eh? Luckily, we're here to make it easy for you. With Quaderno, we'll fill all of that information for you, leaving you free to do the meaningful work.
