How to send an invoice
Best practices for delivering invoices so clients pay faster.
Sending an invoice is not just clicking send — timing, subject lines, and payment convenience all affect how fast you get paid.
The best invoices arrive when the value is fresh in the client's mind, include a one-click payment option, and use a professional template.
Step by step
Review before sending
Double-check amounts, client name, and due date.
Write a clear subject line
Example: "Invoice #1042 from Acme Design — Due April 15"
Include a short message
Thank the client and note how to pay or ask questions.
Attach or link payment
Use a secure payment link so clients pay immediately.
Set reminders
Enable automatic reminders before and after the due date.
Should I send PDF or a link?
Both. Email with PDF attached plus an online payment link covers all preferences.
When is the best time to send?
Right after deliverable acceptance or per your contract schedule — not Fridays before holidays.
