A clear invoice tells your client exactly what they owe, when it's due, and how to pay. Whether you're a freelancer finishing a project or a contractor wrapping up a job, a professional invoice speeds up payment and reduces back-and-forth.
What every invoice must include
- Your business name and contact details
- Client name and billing address
- Unique invoice number (e.g. INV-1002)
- Issue date and due date
- Itemized line items with quantities and prices
- Subtotal, taxes, and total amount due
- Payment terms (Net 15, Net 30, etc.)
