Start free

Free for 5 invoices a month. Pro from £7 a month.

Set for United Kingdom

Made for how the UK invoices.

VAT

20% is the standard rate. 5% applies to a few things such as home energy, and 0% to most food, books and children’s clothes.

VAT registration no.

A VAT registration number is GB followed by nine digits. With it saved, your invoices are titled “VAT Invoice”. Without it they are a plain “Invoice”.

GBP and local dates

Amounts are in British pounds, and you can pick another currency on any invoice. A bank statement you upload is read the way banks in the UK write dates.

Financial year from 1 April

Invoice numbers start a new series each April, so the first invoice of the year is OG/26-27/0001.

FAQ

Questions from the UK.

Does Openn Invoice make a proper VAT Invoice for the UK?

Yes. Add your VAT registration no. in settings and each invoice is titled “VAT Invoice”, with VAT worked out line by line at the rate you pick (20%, 5% and 0%) and totals in British pounds. What it has to show in the UK is listed on this page. Check with your accountant for your case.

Does it file my VAT return?

No. Openn Invoice makes invoices and shows who has paid. It does not file returns or keep full accounts. Paid plans include a tax report and CSV downloads to hand to your accountant.

I am not registered for VAT. Can I still use it?

Yes. Leave the VAT registration no. empty in settings and send invoices with no VAT on them. They are titled “Invoice” instead of “VAT Invoice”. You must register for VAT once taxable turnover passes £90,000 in 12 months.

Can I bill customers outside the UK?

Yes. Pick the customer’s country and currency on the invoice. A customer abroad is billed as an export, with no VAT added. You see the reason on the invoice before you send it.

What does it cost in the UK?

Free covers 5 invoices a month. Pro is £7 a month or £59 a year, with unlimited invoices, recurring invoices and bank statement matching. Prices exclude VAT.
