Why a Good Reminder Email Matters
Most late payments aren't intentional — they're the result of a busy client who let your invoice slip through. A well-timed, professionally worded reminder email solves most late payment issues without conflict. The goal is to prompt action while preserving the relationship.
When to Send Payment Reminders
A standard reminder cadence looks like this:
- 3–5 days before due date: Friendly heads-up reminder.
- On the due date: Brief reminder that payment is due today.
- 7 days after due date: Polite but firm follow-up noting the invoice is now overdue.
- 14 days after due date: More formal notice mentioning late fees if applicable.
- 30+ days after due date: Final notice before escalating to collections or legal action.
