How it's calculated

The reminder is built from the details you enter. It names the invoice, the amount and the due date, makes paying easy (with your pay link if you add one), and gives the client an easy way to raise a problem, which is often why an invoice is late.

Questions

How do I write a polite payment reminder?

Keep it short: name the invoice, the amount and the due date, link to pay, and assume good faith ("If you've already sent it, thank you"). Offer an easy way to ask questions.

When should I send a payment reminder?

Send one a few days before the due date, one on the due date, then every 3 to 7 days after it. Most late invoices are paid after the first or second reminder.

What should a final payment notice say?

That it's the final notice, the amount and how late it is, a clear deadline to pay (usually 7 days), and what happens next, such as the late fees in your agreement or referring the account to collections. Offer a payment plan.

Should I send reminders by email or text?

Both. Email is the record; a text gets read. A short text a day after the email gets many invoices paid the same day.

Can I automate payment reminders?

Yes. Casey sends the reminder before the due date and follows up after it by email, text, WhatsApp or phone until the invoice is paid, in your business's name.
