“I was spending ages formatting VAT invoices in Word and constantly getting the 20% calculation wrong. This tool does it in 60 seconds flat. When I needed proper year-end accounts, Sleek handled my Corporation Tax filing too.“

“As a sole trader I needed something simple that includes my VAT number and looks professional. The BACS details are right there on the PDF — clients pay me faster now.“

Frequently Asked Questions

Is this VAT invoice generator really 100% free?

Yes — completely free to create and download as many VAT invoices as you need. No account, no credit card. If you want to save your client details and track payments, create a free Sleek Accounting account.

Does this meet HMRC requirements for a VAT invoice?

Yes. HMRC requires a VAT invoice to include your business name and address, VAT registration number, a unique sequential invoice number, the date, a description of goods or services, the total excluding VAT, the VAT rate and amount, and the total including VAT. Our tool includes all of these by default.

Can I use this if I'm a sole trader or freelancer?

Absolutely. Whether you’re a VAT-registered sole trader, freelance consultant, or contractor, this tool creates a professional invoice you can send to clients immediately. If you’re not VAT-registered, simply toggle off the VAT switch.

What VAT rates are supported?

The tool defaults to the UK standard rate of 20%. You can manually change this to 5% (reduced rate) or 0% (zero-rated) depending on what you’re selling. The VAT amount recalculates automatically.

Can I add BACS payment details?

Yes. The Bank Details section lets you add your sort code, account number, and bank name so your client knows exactly how to pay you via BACS transfer.

Do I need to include my Companies House number?

If you’re a limited company, yes — it’s a legal requirement to include your registered company number on invoices. Our tool has a dedicated field for this. Sole traders don’t need it.

What happens to my data?

If you use the tool as a guest, your data stays in your browser only — nothing is stored on our servers. For secure cloud storage of all invoices, create a free Sleek account after downloading.

Will this support e-invoicing when it becomes mandatory?

The UK government has confirmed that all VAT invoices must be issued electronically from April 2029 as part of Making Tax Digital. Sleek is preparing for this transition — our tool will be updated to support e-invoicing ahead of the deadline.
