How to do an invoice as a self employed person?
Short answerUse your business name or your own name, a unique invoice number, the date, the customer, itemized work, the total and clear payment instructions. Keep a copy of every invoice for your tax records. A simple template works at first, then move to a tool that creates invoices from your jobs as volume grows.
The explanation
Being self-employed does not change what an invoice needs. It changes who is responsible for the paperwork: you. Put your name or business name and a contact number at the top so the customer can pay and ask questions.
Number invoices in order and never reuse a number. Itemize the work so a customer can see what they paid for. Add a due date and your accepted payment methods. If you charge sales tax, show it as its own line and confirm the rules with your accountant or state revenue office.
Keep records from the start. The IRS asks you to keep documents that support your income and deductions, and a tidy folder of invoices makes tax season much easier. Separate business money from personal money, and move to automatic numbering when handwriting each one becomes a chore.
Steps
- Choose a template with your name and contact details.
- Number each invoice in order, without gaps.
- Itemize services and show any tax.
- Add the due date and payment options.
- File a copy in a dated folder.
What to watch for
- Mixing personal and business accounts.
- Leaving the invoice number off entirely.

Apex is designed for small owners with invoices from jobs, branded templates, a pay link and card processing at the processor's own rate. Branding is partly built and card processing is a demo screen.
