How to send an invoice in 4 steps
- Create the invoice. Add your details and the client’s, the line items, an invoice number and a due date. The generator above does the math and exports a clean PDF.
- Add a way to pay. Paste a Stripe, PayPal.me or Wise link so the client can pay online from the PDF, or add bank details in the payment instructions.
- Attach the PDF and write a short email. Send the PDF with a brief, polite note — what it is for, the total, the due date and how to pay.
- Set the due date and follow up. Use clear terms like Net 14 or Net 30, and send a friendly reminder if the invoice is not paid on time.
What to write in the invoice email
Keep it short. A clear subject line with the invoice number, one or two sentences on what the invoice covers and the amount due, the due date, and how to pay. For example:
Subject: Invoice 0007 from Acme Studio — due 30 June
Hi Sam, please find attached invoice 0007 for the logo design project, total $650, due 30 June. You
can pay online using the link in the PDF, or by bank transfer. Thanks!
How to invoice someone (and get paid faster)
Whether you are invoicing a company or an individual, the essentials are the same: a unique invoice number, clear line items, a total, a due date and an easy way to pay. Adding a payment link is the single biggest thing you can do to get paid faster — it turns “I’ll get to it” into one click. New to this? Start with how to write an invoice or how to create invoices.
Send a receipt once you are paid
After the client pays, send a receipt to confirm it — one click converts your invoice into a receipt. Quoting a job first? Use the quote template, or jump straight to the invoice maker.
Frequently asked questions
What is the best way to send an invoice?
For most freelancers and small businesses, email is the best way: attach the invoice as a PDF so it looks the same on every device, and include a payment link so the client can pay online in one click. Keep the email short and clear.
What should I write in an invoice email?
Keep it brief: a subject line with the invoice number (e.g. “Invoice 0007 from Acme Studio”), one or two lines saying what it is for and the amount due, the due date, and how to pay. Mention that the invoice is attached as a PDF.
How do I let the client pay the invoice online?
Paste any payment URL — a Stripe Payment Link, PayPal.me, or Wise link — into the payment field. It becomes a clickable “Pay online” button (and an optional QR code) right in the PDF, so the client can pay without extra steps.
Can I send an invoice if I am not a registered business?
In many places individuals and sole traders can send invoices, but the rules and required details vary by country and tax status. This is a free general-purpose tool, not legal or tax advice — check what applies to you before you invoice.
When should I send an invoice and how long should the client have to pay?
Send the invoice as soon as the work is delivered or per your agreement. Common terms are Net 14 or Net 30 — set a clear due date so both sides know when payment is expected.
Is the invoice generator free?
Yes — free, no signup, no watermark. Create and download the PDF, then send it however you like. Your data never leaves your browser.
