As a sole trader, a one-person business also called a sole proprietor, you are the whole operation, so your invoice has to look as professional as any company's while carrying only the details that actually apply to you. A good sole trader invoice uses your name or trading name, states clear terms, and gets you paid without the overhead of a limited company's paperwork. Here is what to put on a sole trader invoice, a sample you can copy, and the payment terms that get you paid faster.
What to include on a sole trader invoice
A sole trader invoice needs the standard fields, adapted to a one-person business.
Your name and trading name:: your own name, and your business or DBA name if you use one.
Your contact and tax details:: your address, email, and your tax ID (an EIN if you have one, otherwise your SSN in the US), or the equivalent where you are.
The client's details:: their name, business, and contact.
A unique invoice number:: for both your records.
Invoice date and due date:: an exact due date, not just "net 30."
Itemized services or goods:: each item with a description, quantity, and rate.
Sales tax, if it applies:: any tax you are registered to charge, on its own line.
Subtotal and total:: the amounts and the balance due, with any deposit credited.
Payment details:: how to pay, your bank or payment details, and any late fee.
The one thing sole traders get wrong is thinking a plain email or a bare figure will do. Using a numbered, dated invoice with your trading name and clear terms is what makes a one-person business look established and gets it paid like one.
Sample sole trader invoice
Here is what a realistic sole trader invoice looks like, for a month of services.
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Consulting services (June) | 1 | $1,200 | $1,200 |
| Additional support and calls | 3 hrs | $60 | $180 |
| Materials and expenses | 1 | $45 | $45 |
Subtotal: $1,425 · Total due: $1,425 · Due by [date]
Itemizing your services, listing expenses separately, and stating a clear due date gives a client everything they need to pay, and makes a sole trader's invoice look every bit as professional as a larger firm's.
Build your sole trader invoice for free
You do not need to build this from scratch or wrestle with a spreadsheet. Our free invoice generator lays out every field above, does the math, and downloads a professional PDF in minutes, with no signup. Add your trading name, services, and rates and send.
The free tool is ideal for a one-off invoice. What it does not do is remember your clients or track which invoices are paid and overdue, which matters when you are the only one keeping the books. FileCurrent saves your client details so invoices auto-fill, and it tells you who has paid and who has not.
Payment terms for sole traders
As a sole trader, your cash flow is your business's cash flow, so terms that get you paid promptly matter more than for anyone.
Keep terms short, net 14 or net 15 is reasonable, since you do not have a finance department to carry slow payers. Take a deposit on larger jobs so you are never fully out of pocket, and state an exact due date and a late fee to keep invoices moving. Separate your business banking from your personal accounts so income and tax are easy to track, which the freelance business setup guide covers. The how to invoice as a freelancer guide covers the basics of sending one, and the freelance payment terms guide covers structuring the terms.
Frequently asked questions
What should a sole trader invoice include?
Your name and trading name, your contact and tax details, the client's details, a unique invoice number, the invoice and due dates, itemized services with descriptions and rates, any sales tax that applies, the subtotal and total with any deposit credited, and how to pay. A numbered, dated invoice with your trading name is what makes a one-person business look established.
Do sole traders need a registered company number on invoices?
No. As a sole trader you are not a limited company, so there is no company registration number to show. You invoice under your own name or your trading name, with your tax ID where required (an EIN or SSN in the US). That is one of the simplicities of being a sole trader: less paperwork than a company, and a simpler invoice.
How do I invoice as a sole trader or sole proprietor?
Use a numbered, dated invoice with your name or trading name, the client's details, itemized services with descriptions and rates, a clear due date, and your payment details. Keep it professional, a plain email or a bare number reads as amateur and gets paid slowly. A free invoice generator gives you a proper template without the cost of software.
Do sole traders charge sales tax on invoices?
It depends where you are and what you sell. In the US, most freelance services are not subject to sales tax, but goods and some services are, and rules vary by state, so check your obligations. If you are registered to charge sales tax or VAT, show it as its own line on the invoice. If not, you simply invoice your fee with no tax line.
