Free Invoice Template for UK Freelancers and Sole Traders (PDF)

If you are just starting out as a freelancer or sole trader in the UK, you do not need invoicing software to send your first few invoices. You need a clean, professional template you can fill in and send as a PDF. This one is free, built specifically for UK freelancers, and includes all the fields HMRC requires you to keep on record.

Download it below. Then come back to this page — there is a short guide underneath explaining what goes in each field, including the UK-specific bits that catch people out.

Free download: UK Freelance Invoice Template (PDF) — A4, sole trader ready, VAT note included. No sign-up required.

How to use this template

The template is a single-page A4 PDF designed to be printed and filled in by hand, or opened in a PDF editor and typed into directly. Most PDF readers — including Adobe Acrobat Reader (free), Preview on Mac, and browser-based viewers — let you type into form fields or annotate documents. If yours does not, print it and fill it in neatly in black ink.

Once complete, save it as a PDF and attach it to an email to your client. Do not send it as a Word document or image — PDFs look consistent across devices, cannot be accidentally edited, and feel more professional.

Keep a copy of every invoice you send. HMRC requires sole traders to retain business records for at least five years after the relevant 31 January Self Assessment deadline. A folder on your computer labelled by year works fine.

What goes in each field

Invoice number

Every invoice needs a unique sequential number. Start at 001 — or 100 if you would rather not advertise that this is your first invoice — and go up from there. Your client's accounts team uses this number to track and process the payment. You use it to match payments to your records and to reference invoices if there is ever a query. Never reuse a number.

Your details (From)

Your full legal name, or your business trading name if you use one. If you trade under a different name from your legal name, include both — for example: Sarah Chen trading as SC Photography. Add your address, email, and phone number. If you are VAT-registered, your VAT number goes here too. If you are not registered, leave the VAT number field blank.

Client details (Bill To)

The full legal name of the person or company you are billing, and their address. For business clients, match this exactly to the name on any contract or purchase order they have issued. An invoice addressed to the wrong entity can be rejected by corporate accounts teams and genuinely delay payment. If you are unsure, ask before you send.

Invoice date

The date you are issuing the invoice — not the date the work was completed, though these are often the same. This is the starting point for your payment terms.

Payment due date

A specific calendar date. Not "Net 14" — an actual date: 1 May 2026. Specific dates remove ambiguity. Write them out in full rather than using abbreviated formats, which can be read differently in different countries.

Description of work

Be specific. "Copywriting — April" tells a client and their accounts team nothing. "Website copywriting — homepage and 3 service pages, delivered 18 April 2026" is unambiguous. If you completed multiple deliverables, list each one as a separate line item with its own amount. Specificity reduces queries and speeds up approval.

Amount

The total owed. If you are not VAT-registered, just show the total. If you are VAT-registered, show the net amount, the VAT rate (usually 20%), the VAT amount, and the gross total as separate lines. The template includes a subtotal, VAT, and total due section — leave the VAT row blank if it does not apply to you.

Payment details

For UK bank transfer — the most common payment method for freelancers — include your account name, sort code, and account number. Double-check these before you send. A typo in your sort code or account number means the payment bounces, and untangling a misdirected bank transfer is a genuine headache. If you also accept PayPal or another method, include those details too.

Purchase order number (if applicable)

Many corporate clients issue a PO number when they commission work and require it on any invoice before they can process payment. If your client uses PO numbers, ask for it before you start work. Finding out after you have sent the invoice — and having to reissue it — adds unnecessary delay.

VAT — do you need to charge it?

Most new freelancers are not VAT-registered and should not add VAT to their invoices. You are only required to register for VAT once your taxable turnover exceeds £90,000 in any rolling 12-month period. Below that threshold, you charge no VAT, show no VAT on your invoices, and do not need a VAT number.

If you are VAT-registered, your invoices must show your VAT registration number, the net amount, the applicable VAT rate, the VAT amount, and the gross total. Standard rate VAT in the UK is currently 20%. HMRC's VAT registration guidance covers when and how to register if you are approaching the threshold.

Adding VAT when you are not registered is a legal problem — you would be collecting tax you have no right to collect. When in doubt, leave it off.

Choosing your payment terms

Your payment terms define how long your client has to pay from the invoice date. Common options for UK freelancers:

• Due on receipt — payment expected immediately. Reasonable for small or one-off jobs.
• Net 7 — payment within 7 days. Good for regular clients with a reliable track record.
• Net 14 — payment within 14 days. The right default for most freelancers. Short enough to protect your cash flow, long enough to be reasonable.
• Net 30 — payment within 30 days. Standard in large corporate environments. Fine for established retainer clients; too long as a default for everyone else.

You are not obliged to offer Net 30 just because large companies prefer it. Most clients pay on whatever terms you set without question. The template defaults to Net 14 — change it if your client relationship calls for something different.

Under the Late Payment of Commercial Debts Regulations 2013, UK freelancers are legally entitled to charge statutory interest of 8% above the Bank of England base rate on overdue invoices from business clients, plus a fixed debt recovery charge. The template includes a brief note to this effect in the footer — you do not have to enforce it, but stating it sets a professional tone.

How to send it

Send the invoice the same day you deliver the work. The client is at peak engagement right now — your work is fresh, their satisfaction is high, and payment is the natural next step. Every day you wait adds a day to your payment timeline for no reason.

Attach the completed PDF to an email with a brief covering note:

Hi [Name], please find attached invoice #001 for [brief description], due [date]. My bank details are on the invoice — do let me know if you need anything else to process it.

No apology. No hedging. Professional and warm. If you have not heard anything by the due date, follow up the same day with an equally brief note referencing the invoice number and amount.

When you outgrow a template

A PDF template works well for your first few invoices. Once you are sending more than a handful a month, the manual process starts to add up — filling in the same client details repeatedly, keeping track of which invoices are paid, chasing overdue payments by hand, and searching through files at tax time.

That is the point at which invoicing software earns its keep. GigInvoice saves your client details so you never retype them, auto-numbers every invoice, sends them directly by email with read tracking, and lets you mark invoices as paid or overdue at a glance. It takes under 60 seconds to create an invoice, and your records are always in one place when Self Assessment comes around.
