Can I invoice without a company as a sole trader?

Yes. A sole trader has no separate legal company, so you invoice under your own name or a trading name. The invoice is just as valid as one from a limited company as long as it is clear, dated, numbered, and accurate.

What do I put instead of a company number on a sole trader invoice?

Use your full name and any trading name, your contact address, your payment details, and any required tax reference such as a personal tax ID, a self-assessment reference, or a VAT number if you are registered. You do not need a company registration number.

Do sole traders need to show tax on invoices?

Only if you are registered to charge sales tax or VAT. If so, show it as a separate line so the amount is clear. If you are not registered, you simply do not include it. Specific rules depend on your country, so check your local tax authority.

What payment terms should a sole trader use?

Short terms such as Net 7 or Net 14 work well because late payments hit self-employed income directly. State a clear calendar due date and follow up promptly once an invoice is overdue.

How to invoice as a sole trader

Updated June 2026

You don't need a registered company to send a professional invoice. As a sole trader or self-employed person, you invoice under your own name, and a clean, complete invoice carries exactly the same weight as one from a limited company. This guide walks through what to put on a sole trader invoice — including what goes where a company number normally would — and how to set terms that get you paid on time. It is general guidance, not country-specific tax advice.

You invoice as yourself

The thing that trips people up first: a sole trader has no separate legal company, so there's no company registration number to quote. That's completely fine. You bill in your own name (or a trading name you operate under) and the invoice is just as valid. What matters to a client — and to the tax authorities — is that the document is clear, dated, numbered, and accurate. Everything else is presentation. If you want the underlying basics first, read how to write an invoice and then apply the sole-trader specifics below.

What to put instead of a company number

Your full name, and your trading name if you use one ("Jane Smith trading as Smith Design").
Your business address or a contact address — wherever clients can reach you.
Your tax reference where required. Depending on your country this might be a personal tax ID, a self-assessment / UTR-style reference, or a sales-tax/VAT number if you're registered for it. If you aren't registered for sales tax, you simply don't show one.
Bank or payment details in your own name so the client knows exactly where to send the money.

You do not need to invent a company number or register a company just to invoice. Operating as a sole trader is a recognized way to be in business.

The fields every sole trader invoice needs

1A unique invoice number.

Sequential numbering (001, 002, 003) keeps your records straight and makes tax time far easier. Start simple and stay consistent.

2Issue date and due date.

Always give a real calendar due date. "Payable within 14 days" with the actual date spelled out removes any ambiguity about when payment is late.

3An itemized description.

List what you did, the quantity or hours, the rate, and the line total, then a clear subtotal, any tax, and a bold grand total.

Keeping it simple and tax-ready

As a sole trader you are usually responsible for tracking your own income and setting aside money for tax, so your invoices double as your income records. Keep a copy of every invoice you send, number them in order, and note when each one is paid. If you charge sales tax or VAT, show it as a separate line so the amount is unmistakable. Specific rates, thresholds, and registration rules depend on where you operate — check your local tax authority rather than relying on a template to decide that for you.

Getting paid on time

Sole traders feel late payments more sharply than larger businesses because there's no buffer — it's your income directly. Use short terms like Net 7 or Net 14, state them clearly, and follow up the moment an invoice goes overdue. A polite reminder before the due date and another every few days after it is the single most effective habit for getting paid. For more on structuring terms, see invoice payment terms.
