How to Send Invoices as a Freelancer (and Actually Get Paid)
Sending a freelance invoice isn't just about the PDF. It's the wording, the timing, the payment method, and the follow-up. Do all four well and your average payment time drops in half.
What every freelance invoice must include
- Your business name, address and tax/VAT number (if applicable).
- The client's full company name and billing address.
- A unique invoice number — sequential, never duplicated.
- Issue date and a clear due date (not 'on receipt').
- Line items: description, quantity, rate, amount.
- Subtotal, tax/VAT, total in the correct currency.
- Payment methods: card link, bank transfer details, or both.
How to write line items that don't trigger questions
Vague line items create disputes. 'Design work' invites a reply asking what exactly. 'Homepage redesign — 12 hours @ £80' is unambiguous and gets paid faster. Write line items the way you'd want to read them as the person approving the payment.
When to send the invoice
Send on delivery, not at the end of the month. Every day you delay is a day added to your payment cycle. For ongoing retainers, send on the same calendar day each month so it becomes predictable for the client's finance team.
Setting payment terms that actually work
- Net 7 for small clients — they have no AP queue, just pay it.
- Net 14 for mid-size businesses with a finance person.
- Net 30 only if the contract says so. Never default to it.
- Add a late fee clause: 1.5% per month past due, stated on the invoice.
Make it one click to pay
Every freelance invoice in 2026 should include a Pay Now button that opens Stripe or another card processor. Bank transfer alone adds days. A card link gets paid in minutes — sometimes seconds.
Following up without sounding annoying
Schedule three reminders: three days before due, on the due date, three days after, and a final note at seven days overdue. Keep them short, polite and reference the invoice number. PortalHQ sends these automatically so you never have to draft another chase email.
