Invoice

A formal document you send to a client or business requesting payment for goods or services delivered. It specifies the amount, payment terms, and bank details.

An invoice is your legal request for payment. Without one, you have no formal record of what is owed or when. Proper invoicing protects you under the Late Payment Act.

You complete a brand photography project for £600. You send an invoice stating: services delivered, amount £600 + VAT, payment due within 14 days, your bank details.
