What are the steps to make an invoice?
An invoice is a request for payment, so each step answers a question the client will have:
- Add your business name and contact details, and the client's.
- Give it a unique invoice number and today's date.
- List each product or service with quantity, rate and amount.
- Show the subtotal, any discount and tax, then the total.
- Write the payment terms, such as Net 14, and the due date.
- Say how to pay, then save it as a PDF.
What does a finished invoice look like?

Which tool should you use?
A free invoice template adds up the lines for you. You can also build one in Word or a spreadsheet, but then you set up the totals and the numbering yourself.
What do you do after you make it?
Send it the same day the work is done, because terms usually count from the invoice date. How to send an invoice covers the email, and a polite note helps: see the invoice email template.
