Common mistakes

No due date

"Payment terms: 14 days" and the actual date make it far more likely to be paid on time.

Forgetting the deposit

If they paid a deposit, show it as a deduction so the amount due is right first time.

Questions

What must a UK invoice include?

Your business name and contact details, the customer's details, an invoice number, the date, what was supplied, the amount due, and your VAT number if you're VAT registered.

When should I send the invoice?

As soon as the job is finished. The sooner it lands, the sooner it's dealt with.

Should I show VAT separately?

Yes if you're VAT registered: show the net amount, VAT and the total.
