When to use this invoice
Send a freelance invoice whenever you finish a project, reach a payment milestone, or close out a month of hourly work for a client. It tells the client exactly what they owe, what it’s for, and how and when to pay you.
It’s built for designers, writers, developers, photographers, consultants and other independent contractors who bill by the hour, by the project or on a retainer.
How to fill it out
Replace every item in [brackets]. Here’s what goes in each field.
| Field | What to enter |
|---|---|
| Your name or business name | The name the client knows you by. If you have an LLC or a DBA, use that name. |
| Your contact details | Street address, email and phone so the client’s accounts team can reach you. |
| Invoice # | A unique number that never repeats. A simple sequence (0001, 0002) or a date-based number (2026-11-01) both work. |
| Invoice date | The day you send the invoice. |
| Due date | The date payment is due. Count it from the invoice date using your terms. |
| Terms | How long the client has to pay. “Net 15” means 15 days from the invoice date. “Due on receipt” means right away. |
| Bill to | The client’s name, company and billing address. Ask who handles payments, since it’s often not the person you work with day to day. |
| Project | The project name, or the purchase order (PO) number if the client gave you one. Many companies won’t pay an invoice without their PO number. |
| Line items | One row per service or deliverable, with hours or quantity, your rate, and the amount (quantity × rate). |
| Subtotal, discount, tax, total | Add up the line items, subtract any discount, then add sales tax if it applies to your service in your state. |
| Payment methods | Exactly how you want to be paid: bank transfer, Zelle, PayPal, check, or a payment link. |
| Notes | Your late-fee policy, if you have one, and a short thank-you. |
Tip: Save each invoice as a PDF before you send it, named with the invoice number and client, for example
0007-Acme-Co.pdf. PDFs can’t be edited by accident and look the same on every device.

The rest of that invoice reads:
- Invoice #: 0007

- Payment methods: ACH bank transfer or Zelle to billing@example.com
- Notes: A late fee of 1.5% per month applies to balances unpaid after the due date. Thank you for your business!
No sales tax appears here because many states don’t tax design services. Check your own state’s rules.
Common mistakes to avoid
- Reusing an invoice number. Duplicate numbers confuse both your records and the client’s accounting system. Every invoice gets a new number, even a corrected one.
- Leaving out the due date. “Net 30” alone makes the client do math. Spell out the actual date.
- Vague line items. “Design work: $2,000” invites questions and delays. Name the deliverable and show hours or quantity.
- Missing the PO number. If the client uses purchase orders, an invoice without one often sits unpaid in accounts payable.
- Sending to the wrong person. Your day-to-day contact may not be the one who pays. Ask for the billing contact at the start of the project.
- Not saying how to pay. Every extra email asking “how do I pay you?” adds days to your payment.
Frequently asked questions
What is the difference between an invoice and a receipt?
An invoice asks for payment and is sent before you’re paid. A receipt confirms that payment was received and is sent after.
Do freelancers need to charge sales tax?
It depends on your state and what you sell. Many states don’t tax services like writing or consulting, but some tax digital products or certain services. Check your state’s department of revenue website, or ask an accountant.
What payment terms should I use?
Net 15 and Net 30 are the most common. Shorter terms get you paid faster, so use Net 15 or “due on receipt” for new or small clients unless they ask for longer.
Can I charge a late fee?
Yes, if you told the client about it upfront, ideally in your contract and on every invoice. A common rate is 1% to 1.5% per month, but some states cap late fees, so check your state’s limit.
Do I need a business license to send an invoice?
No. You can invoice under your own name. Some cities and states require a license to operate a business, which is separate from invoicing, so check your local rules.
