Sending your first freelance invoice is simpler than it looks — but doing it right is the difference between getting paid in a week and chasing a client for a month. This guide covers exactly what an invoice needs, how to set terms that get you paid faster, and how to keep track once you have a few clients.
Required fieldsWhat every invoice must include
At a minimum, a professional invoice shows:
- Your details — name or business name, address, email, and phone.
- The client's details — company name and billing contact.
- A unique invoice number — so both sides can reference it (e.g. 2026-014).
- Issue date and due date — not just "Net 30," an actual date.
- Line items — a clear description of the work, quantity or hours, rate, and line total.
- Subtotal, any tax, and the total due. (Every field, with a worked layout, is in how to create an invoice.)
- Payment details — how to pay you (bank transfer, PayPal, etc.).
- A short note — thank-you plus your terms (late fee, deposit policy).
If any of these are missing, expect delays and questions.
Step by stepStep-by-step: create and send the invoice
- 01Open the Invoice Generator. Add your details and your client's.
- 02Add line items. Bill by project ("Landing page design — $1,200") or by hours ("Design, 12 hrs × $85"). Be specific — vague line items get disputed.
- 03Set the dates and terms. Choose an issue date and a real due date (Net 15 or Net 30). Shorter terms get you paid faster; Net 15 is completely normal for freelancers.
- 04Add tax if it applies. Whether you charge sales tax / VAT / GST depends on your location and the service — when in doubt, check locally. (Income tax on what you collect is separate and, in the US, paid quarterly.)
- 05Add your payment details so there is zero friction to pay you.
- 06Download the PDF and send it — email it as an attachment with a one-line message.
Getting paidHow to get paid on time (this is the real skill)
- Invoice immediately. Send it the day the work is delivered, not at month-end.
- Use short terms. Net 15 is reasonable and speeds up cash flow. State the due date as a date.
- Ask for a deposit on larger projects — 30–50% up front protects you. Trades do this on the quote, before any invoice exists — the quote-to-booked-job sequence shows the wording that gets a deposit paid.
- Add a late-payment line ("1.5% monthly on overdue balances") — you rarely charge it, but it sets the tone.
- Follow up on a schedule. A polite nudge the day after the due date, then weekly. Most late payments are just forgotten, not refused.
Once you have more than a couple of clients, tracking who has paid in your head (or a spreadsheet) breaks down. The Invoices Tracker shows what is outstanding, what is overdue, and your total collected — so you always know where you stand and who to chase.
FAQFrequently asked questions
Do I need to charge sales tax as a freelancer? It depends on where you are and what you sell — services are often treated differently from goods. Check your local rules; the invoice tool lets you add tax when it applies.
What is a good invoice number format? Anything sequential and unique works. A common format is year + number, like 2026-014. Never reuse a number.
What are normal payment terms? Net 15 and Net 30 are standard. For freelancers, Net 15 (or even "due on receipt") is completely reasonable and improves cash flow. The difference is measurable: every $10,000 waiting 30 days costs about $82 on a 10% line of credit.
What if a client does not pay? Send a firm but polite reminder after the due date, then follow up weekly. Reference the invoice number and due date. Having sent a clear, professional invoice (with terms) makes this far easier — and the Invoices Tracker flags overdue ones so nothing slips.
Should I send a PDF or a link? A PDF is the safe default — it looks professional and every client can open it. The Invoice Generator downloads one instantly.
