Getting paid in United Kingdom

Common ways to pay are UK bank transfer (sort code and account number) or card payment. Typical payment terms: 30 days is the common default, and many businesses use 14. UK law allows statutory interest and fixed compensation on overdue business-to-business invoices in many cases. Check the details on GOV.UK.

Mistakes to avoid

No clause on who owns the code until the invoice is paid.
Mixing one-off project fees with monthly maintenance.
Charging VAT when you are not VAT-registered.
Missing the VAT number on a VAT invoice.

Practical tips

Invoice per milestone so cash arrives during the project, not only at the end. If you bill hourly, attach or summarise a timesheet.

The standard VAT rate is 20 percent, with reduced and zero rates for some goods and services. Registration is compulsory once taxable turnover passes the government threshold, and the figure is updated from time to time, so check GOV.UK. Under the UK late payment law, businesses can charge statutory interest and fixed compensation on overdue invoices between businesses, unless contract terms provide a substantial alternative remedy.

Frequently asked questions

Should developers bill hourly or fixed price?

Fixed prices suit well-defined scopes, hourly suits changing requirements. Many developers combine the two: a fixed price per milestone with hourly billing for changes.

When does the client own the code?

That is set in your contract. Many freelancers transfer ownership on full payment. Put the rule in your agreement and mention it on the invoice.

Do I need to be VAT-registered to send an invoice in the UK?

No. Only VAT-registered businesses charge VAT. Others can still send normal invoices without VAT.

What must a UK VAT invoice include?

A sequential number, your VAT number, dates, customer details, description, net amount, VAT rate and VAT amount, and the total.
