How to use this invoice generator

Designed for small business owners in the UK, our VAT invoice generator is suitable for a wide range of applications – from construction work and contractor invoicing to invoicing for consultations and creative work. Invoice online with minimal time, effort or technical knowledge by following these steps:

Fill in the invoice template

Enter your customer’s details as well as a breakdown of the goods and services provided. You can add your details and your company logo to the invoice under “sender’s details”.

Make sure to include an invoice number, product information, due date and anything else you may need from the “Add item” drop down list.

Preview your PDF invoice

It’s important to review your invoice before sending by clicking “Preview”. This invoice generator allows the creation of PDF invoices, but we also have Word, Google Doc and Excel invoice templates

We’ve spent years developing and improving our professionally designed invoices to make them intuitive, practical and great to look at.

Generate and download your invoice

Once reviewed, download your PDF invoice and send it to your client.  If you need some help drafting the email which you attach this invoice to, see our article on writing the perfect invoice email.
