Do I need a VAT number to send an invoice?

Only if you're VAT registered. If you're not, don't add VAT — send a plain invoice.

What's the difference between a full and a simplified VAT invoice?

A simplified invoice is allowed for sales of £250 or less if your customer agrees, and needs fewer details. Above £250 you need a full VAT invoice.

What currency and VAT rate does this use?

GBP and 20% VAT, set for you. You can change either for a different rate or an overseas client.

Do you keep my invoice?

What an invoice needs in the United Kingdom

A full VAT invoice needs a unique, sequential invoice number, the time of supply and the issue date, and your and your customer's names and addresses.
Each line needs a description, the quantity, the VAT rate and the net amount, and the total VAT must be shown in pounds.
For sales of £250 or less, a simplified invoice is allowed if the customer agrees: your name, address and VAT number, the time of supply, a description, and the total including VAT with the rate.
Only charge VAT if you're registered. You must register once your taxable turnover goes over £90,000 in 12 months.
