Payment reminder FAQ

How many reminders should I send?

A common rhythm is a friendly nudge before or just after the due date, a firm follow-up inside the first week, and a final notice around two weeks — each shorter and more direct than the last.

Should I include the payment link every time?

Yes. Every extra step between the reminder and paying costs days. Include the same direct payment link in every message, email or SMS.

Can reminders be automated?

Yes — Workspace369 workflow automations send invoice follow-up emails and SMS on a schedule, branch on whether the invoice is still unpaid, and create a task for a person when it is time to call. Free for 14 days.
