Free Invoice Template for UK Freelancers (No Sign-Up Required)

A Free Invoice Template That Actually Works for UK Freelancers

The free Invoice Generator on ToolsForTasks creates a UK invoice in two minutes, no sign-up required. Fill in your details, your client's details, and the line items. Add VAT if you're registered. Download the invoice, open it in your browser, and print it or save it as a PDF. The whole thing happens in your browser, so your client data never goes near a third-party server. This guide covers exactly what a UK freelance invoice has to include by law, the difference between sole trader and limited company invoices, how to handle VAT, and the late-payment terms that get you paid on time.

At a Glance

• UK invoices must include 9 specific items (we list them all below)

• VAT-registered freelancers must show their VAT number, rate, and amount separately

• If no payment date is agreed, payment is due 30 days after the client gets the invoice (or the work, if that comes later). Statutory late-payment interest: 8% above Bank of England base rate

• The Late Payment of Commercial Debts Act gives you the right to claim interest plus a fixed fee

• Sole traders show their own name; limited companies show their full registered company name

What a UK Freelance Invoice Must Include

GOV.UK lists nine items every invoice must include:

1. A unique invoice number

2. Your name or company name, address and contact information

3. The client's name and address

4. A clear description of the goods or services

5. The date of supply (when the work was done)

6. The date of the invoice

7. The amount or amounts charged

8. The VAT amount, if applicable

9. The total amount owed

If you and your client are both VAT-registered, you must issue a VAT invoice, which also needs:

1. Your VAT number

2. The VAT rate applied (usually 20% standard, sometimes 0% or 5%)

3. The VAT amount shown separately from the net total

Sole traders must show their own name and any business name they use, plus an address where legal documents can reach them if they trade under a business name. Limited companies must show the full company name as it appears on the certificate of incorporation, and if you put any directors' names on your invoices, you must include them all.

How to Create an Invoice in 2 Minutes

1. Open the Invoice Generator

2. Enter your name, address and contact details in the From box, with your VAT number if you're registered

3. Enter the client's name and address in the Bill To box

4. Type the invoice number (it starts at INV-001 and does not count up for you, so keep your own list)

5. Add line items: description, quantity, rate

6. Enter your VAT rate in the Tax Rate box if you're registered (the invoice calls the line "Tax")

7. Pick the due date, and choose GBP (£) in the Currency box, as the tool starts in US dollars

8. Put your bank details, and the supply date if it differs from the invoice date, in the Notes box

9. Download the invoice, open the file in your browser, and print it or save it as a PDF

The invoice is yours. Save it as a PDF from your browser's print option, then send it as an email attachment, upload it to a client portal, or print and post it if you really want to. There's no watermark, no upsell, no account required.

A graphic designer in Cardiff who switched from a £15/month SaaS invoicing tool to the free version wrote in to say she ran her entire £42,000 turnover through the free generator for a year, and the only thing she missed was automated reminders, which she replaced with a recurring calendar entry.

Sole Trader vs Limited Company: What Goes on the Invoice

The format differs in three ways.

Name. Sole traders use their own name. You can include a trading name (for example "John Smith trading as Smith Design"), but your real name has to appear. Limited companies use the registered company name (for example "Smith Design Ltd").

Registered details. A limited company must show its registered number and registered office address on its business letters, order forms and website, and it makes sense to put them on invoices too. Sole traders don't have either. If you're a sole trader using a business name, show an address where legal documents can reach you, but you don't need a registration number.

VAT registration. Both can be VAT-registered. The threshold is £90,000 turnover (2024/25 onwards). Below that, registration is voluntary. If you're not registered, don't show a VAT number, don't add VAT to the invoice, and don't include a "VAT amount" line.

Adding VAT Correctly

If you're VAT-registered, you must give a VAT invoice to any VAT-registered customer, and HMRC's guidance says that in practice you will probably give one to anyone who asks. Three rules:

1. Show VAT separately. Net amount on one line, VAT amount on the next, gross total at the bottom. Don't bundle them into a single number.

2. Use the correct rate. Most goods and services are 20% (standard rate). Some are 5% (reduced rate, for example domestic energy). Some are 0% (zero-rated, for example children's clothing). Some are exempt (for example financial services). Use the VAT Calculator if you need to work out the gross from the net or vice versa.

3. Include your VAT number. Format: GB followed by 9 digits (sometimes followed by a 3-digit branch identifier). HMRC issues this when you register.

If you're using the Flat Rate Scheme, you still charge customers the standard 20% but you pay HMRC a flat percentage of your gross turnover. Your invoice doesn't change; just your bookkeeping.

Setting Payment Terms That Get You Paid

If you and your client haven't agreed a payment date, the law says payment is late 30 days after the client gets the invoice, or after you deliver the work if that is later. You can agree shorter terms (contracts often specify 14 days or "on receipt") or longer ones: for business customers an agreed date must usually be within 60 days, and a longer period must be fair to both businesses.

Three terms worth using on every invoice:

• Due date stated explicitly, not "30 days from issue". Calculate the date and write it.

• Bank details in full: sort code, account number, account name, and reference (your invoice number).

• Late payment notice stating that statutory interest applies at 8% above Bank of England base rate plus a fixed fee under the Late Payment of Commercial Debts Act.

The fixed fees depend on the size of the debt: £40 up to £999.99, £70 from £1,000 to £9,999.99, and £100 for £10,000 or more. Add these to your reminder when chasing late payers.

A copywriter in Brighton told us she added the late-payment notice to her invoice template in mid-2025. Her average days-to-payment dropped from 38 to 22 within four months. The threat of statutory interest makes a difference even when you don't actually claim it.

Sending the Invoice Professionally

Five small details that make freelance invoices look like they came from an established business:

• Use a PDF, not a Word document. Open the file from the Invoice Generator in your browser and save it as a PDF from the print option.

• Name the file properly. "Invoice 2026-042 Smith Ltd.pdf", not "invoice.pdf".

• Include a polite cover note in the email. "Hi [name], please find attached invoice [number] for [project]. Payment is due by [date]. Let me know if you need anything else."

• CC the client's accounts inbox if you have one. Speeds up payment.

• Reference the invoice number in the bank transfer details. Otherwise the client's bookkeeper has to match it manually, which slows things down.

Common Invoicing Mistakes

Inconsistent invoice numbers. Skipping numbers (going from 042 to 044 with no 043) confuses bookkeeping and triggers HMRC questions during audits. Use sequential numbers, no gaps.

Forgetting the "VAT" line when registered. If you're VAT-registered and you forget to charge VAT on an invoice, you still owe HMRC the VAT. You'll have to absorb it from your fee.

Backdating invoices. Don't. The date of issue is the legal record. Invoice on the day you finished the work or the agreed billing date.

Vague descriptions. "Consulting" doesn't tell HMRC or the client's accountant what was supplied. Use specific descriptions: "Brand strategy session, 4 hours, 12 March 2026."

Forgetting to set a payment due date. "30 days" is implied but a client always pays faster when they see "Due by 25 May 2026" in bold.

What Happens When a Client Doesn't Pay

The Late Payment of Commercial Debts Act gives every UK business and sole trader the right to:

1. Charge statutory interest at 8% above Bank of England base rate from the day after the payment was due

2. Charge a fixed fee (£40 to £100 depending on invoice size)

3. Recover reasonable debt-recovery costs above the fixed fee

You don't have to invoke these rights. Most freelancers don't, because the relationship matters more than the £40 fee. But the existence of the right tends to focus minds when you raise it in an overdue email.

If a client genuinely won't pay, the small claims court (Money Claim Online for under £100,000) handles unpaid invoices and the £35-£455 fee is recoverable from the debtor.

Frequently Asked Questions

Do I need to register for VAT as a freelancer?

Only if your taxable turnover exceeds £90,000 in any rolling 12-month period (2024/25 threshold). Below that, registration is voluntary. Some freelancers register voluntarily to reclaim input VAT or to look more established. If you're not sure, check with an accountant.

What's the difference between an invoice and a receipt?

An invoice is a request for payment. A receipt is proof that payment has been made. As a freelancer you mostly issue invoices; you might issue a receipt if a client pays in cash and asks for one. The free Receipt Generator handles those.

Can I send the same invoice template to clients in different countries?

UK rules apply to UK-issued invoices regardless of where the client is. If you're VAT-registered and supplying services to a business in another EU country, the reverse-charge rules apply (you don't charge VAT but you must note the rule on the invoice). For non-EU clients, you generally don't charge VAT. The VAT Calculator won't decide this for you - check HMRC guidance for your specific situation.

How long do I need to keep my invoices?

Six years from the end of the tax year they relate to. HMRC can request them for audit during that period. Save the PDF copies in a clearly named folder. Cloud backup is essential.

Can I issue an invoice before doing the work?

Yes, but it's then a "proforma invoice" and not legally an invoice. Use a proforma to confirm a price before work starts; issue a real invoice once the work is done. Some clients require a proforma to raise a purchase order on their side.

What if I want to charge in a different currency?

The Invoice Generator lets you pick the currency. For accounting purposes, convert to GBP at the date of supply for HMRC reporting. On a VAT invoice, the total VAT must also be shown in pounds. The Currency Converter gives daily exchange rates for 20 major currencies.
