The freelancer invoicing checklist: everything to include

What every freelance invoice needs

A professional invoice makes it effortless for a client to pay you. Miss a detail and you invite delay. Here's the complete checklist:

• The word “Invoice” and a unique, sequential invoice number
• Your name/business, contact details, and logo
• Your client's name and billing details
• The invoice date and a specific due date
• An itemized list of work — hours × rate, or a fixed fee
• Subtotal, any tax, discounts, and the total due
• Payment terms and how to pay (bank details or a link)

Common mistakes that delay payment

Avoid these and you'll cut days off your payment times:

• No due date (or a vague one) — always state an exact date.
• Vague line items the client can't approve at a glance.
• Sending from a generic address instead of your own.
• Forgetting your payment details or a tax number when required.
