Self-Employed Invoice Template (UK)
The first invoice you send as a self-employed person is a small rite of passage, and it usually arrives with a cluster of questions: can I even invoice before HMRC sends my UTR, what has to be on the page, and is it unprofessional to ask for money up front? The short answers are yes, less than you think, and no. An invoice is just a clear, numbered request for payment — your name, the client, what you did, what it costs, and how to pay — and nothing about issuing one requires a registration, a company, or anyone's permission. This free self-employed invoice template gives you that page, filled out properly, in a couple of minutes.
The generator below is pre-filled with a realistic freelance example — a copywriter billing an agency against a purchase order, deliverables itemised, no VAT — and every field is editable. Swap in your details, download the PDF, and it's ready to send; Word and Excel versions of the same layout are further down the page. Below that you'll find a step-by-step walkthrough and straight answers to the questions that come with going self-employed: deposits, day rates, what HMRC actually needs from you and when, and what to do the first time a client goes quiet at payment time.

How to fill out a self-employed invoice
Lead with your name, as the business
Self-employed means you are the business, so your own name heads the invoice — on its own, or with a descriptor the way the sample uses "Priya Shah — Copywriting". If you've adopted a proper trading name, show your real name alongside it. Clients pay a person; the paperwork should make that person unmistakable.
Add your address and contact details
An address you can receive post at, plus the email and phone the client already knows you by. This block is what a client's bookkeeper uses to set you up as a supplier, so keep it identical from invoice to invoice — same wording, same order — and their records will match yours without a query email every month.
Number it, date it, give it a deadline
Start a single sequence with your first invoice — the sample sits at INV-0027 — and never reuse or skip numbers without reason; the series becomes the backbone of your tax records. Add the issue date, then a due date with a number in it. "Within 14 days" gets you paid; "on receipt" gets you queued.
Name the client the way their accounts team would
Invoice the entity that engaged you: the agency, the company's registered name, or the individual. Agencies and larger clients almost always issue a purchase order or booking reference — put it near their address, the way the sample carries PO 2216, because on many accounts systems an invoice without its PO simply waits.
Itemise the work in the client's language
One line per deliverable, described the way the client would describe it: four service pages at the page rate, two articles at the article rate. Whether you bill by the day, the word, the session, or the project, show the quantity and the rate so the total explains itself — totals that explain themselves get approved without a call.
Skip VAT unless you're registered
Most people starting out aren't VAT registered, and their invoices carry no VAT rate, no VAT amount, and no VAT number — set the rate to 0 and the template renders clean. If you register later, your VAT number joins the header, VAT appears on every taxable line, and net, VAT, and gross totals show separately.
Show the total and how to pay it
One clear total, then the bank details: account name, sort code, account number. Make the account name match the name at the top of the invoice, because that's what your client's banking app checks before it lets them pay. Ask for the invoice number as the reference and reconciling becomes a glance, not a hunt.
File your copy — January will thank you
Save the finished PDF with the number and client in the filename, and record when it gets paid. Your invoices are the income half of your Self Assessment records, kept for years after each return. A folder of numbered PDFs plus a simple paid/unpaid list is a bookkeeping system — a perfectly adequate one, for a while.
Billing tips when you're self-employed
Don't wait for your UTR to send your first invoice
Nothing about invoicing requires HMRC's blessing: bill from day one. What HMRC does require is that you register for Self Assessment once self-employment income starts — the deadline is 5 October after the end of the tax year you began in — after which your UTR arrives for your tax return, not your invoices. The UTR never goes on an invoice anyway. Earnings within the £1,000 trading allowance may not need a return at all, but check GOV.UK before relying on it.
Take deposits from new clients — it's standard, not rude
A deposit or up-front instalment is normal freelance practice, and clients who plan to pay were never scared off by it. Common patterns: 50% before work starts on fixed-price projects, or the first week billed in advance for ongoing bookings. Invoice the deposit like anything else, then subtract it as a negative line on the final invoice so the arithmetic is visible. The first invoice a new client pays also quietly proves their payment process works.
Recharge expenses openly, not buried in the fee
Travel, stock photography, print costs, software bought for one project — if the client agreed to cover it, put it on its own line at cost, with the receipt available on request. Expenses folded silently into the fee inflate your rate in the client's records and understate your costs in yours. Agree in writing which expenses are billable before spending, because "I assumed you'd cover it" is the least winnable dispute in freelancing.
Working in construction? CIS changes your invoice
If you're a self-employed tradesperson working for contractors rather than homeowners, the Construction Industry Scheme applies: the contractor deducts tax from the labour part of your invoice and pays it to HMRC on your behalf. That makes the labour/materials split on your invoice matter enormously. The CIS invoice template on this site is built exactly for that arrangement — use it instead of a general layout for contractor work.
Chase politely, then charge interest
When a business client goes quiet past the due date, escalate in small steps: a resend, then a short reminder naming the balance, then a phone call. Behind the politeness sits real law — business-to-business invoices accrue statutory late-payment interest plus a fixed recovery fee once overdue, no prior warning required. The late payment interest calculator on this site turns an overdue invoice into an exact figure, which is often the number that finally gets it paid.
What a UK self-employed invoice must include
- Your name and address — with your trading name too, if you use one
- The client's name and address, plus any PO or booking reference they issued
- A unique, sequential invoice number
- The invoice date and a specific due date
- A description of the work, with the amount for each line
- The total amount payable
- Your payment details — account name matching the name on the invoice
- VAT number and separate net/VAT/gross totals — only if VAT registered
Your UTR and National Insurance number stay off the invoice — they identify you to HMRC, not to clients. Invoicing itself needs no registration; just register for Self Assessment by the 5 October after your first tax year ends.
Frequently asked questions
Can I invoice a company before I've registered with HMRC?
Yes. Invoicing requires no registration, no UTR, and no waiting — you can bill for your first piece of work the day you deliver it. Registering for Self Assessment is a separate obligation with its own deadline: 5 October after the end of the tax year in which your self-employment began. Do both, but never delay an invoice for the paperwork, because the invoice is what starts the payment clock.
What has to be on a self-employed invoice?
Your name and address, the client's name and address, a unique sequential invoice number, the date, a description of the work with an amount per line, the total due, and your payment details and terms. VAT information appears only if you are VAT registered. No UTR, no National Insurance number, no signature — UK invoices need none of those to be valid.
Should I bill a day rate, an hourly rate, or per project?
Whatever you agreed — the invoice just has to show it clearly: quantity times rate for days or hours, one line at the fixed price for a project. Day rates suit contract and agency work, project prices suit defined deliverables, and hourly suits open-ended support. On the page they all look the same: a line the client recognises, a rate they agreed to, and a total that multiplies out correctly.
Do I charge VAT as a self-employed person?
Only if you are VAT registered, which most people starting out are not. Registration becomes compulsory when taxable turnover over a rolling twelve months passes the threshold HMRC publishes on GOV.UK — check the current figure there rather than trusting a remembered one. Until then, your invoices show no VAT at all. After it, every invoice for taxable work carries your VAT number and separate net, VAT, and gross totals.
Can I ask for payment up front?
Yes, and for new clients you probably should. A 50% deposit on fixed-price work or the first period billed in advance is standard practice, filters out clients who never intended to pay promptly, and funds any materials or costs you carry. Invoice the advance like any other invoice, and show it as a deduction line on the final bill so the client sees exactly how the numbers land.
What records do I need to keep?
Every invoice you issue, every business expense receipt, and a record of what was paid and when. HMRC expects self-employed records kept for years after each return's deadline, and the invoice numbering sequence is what makes yours auditable. A numbered folder of PDFs and a running income list genuinely suffices at the start; when clients multiply, the Paid app on iPhone keeps invoices, clients, and paid/unpaid status in one place.
"Self-employed" and "sole trader" — is there a difference?
Self-employed is the tax status — you work for yourself and pay tax through Self Assessment. Sole trader is the business structure most self-employed people use: trading as yourself, no company. Freelancers, contractors, and tradespeople are usually both at once. The invoices are identical either way; this site's sole trader invoice template covers the same ground with more on trading names and business bank accounts.
A client is ignoring my invoice — what now?
Resend it, since buried invoices are genuinely common, then follow with a short reminder stating the balance and original due date, then call. If the client is a business, statutory late-payment interest and a fixed recovery cost have been accruing since the due date passed — the calculator on this site gives you the exact figure to quote. Most invoices get paid at the reminder stage; the interest letter resolves most of the rest.
Is this self-employed invoice template really free?
Yes — fill it in and download the PDF, Word, or Excel version with no signup and no watermark, for the first invoice or the five hundredth. When repeat clients and monthly billing become the routine, the Paid app on iPhone takes over the retyping — saved clients, repeat invoices, and payment tracking — but the template never depends on it.
