Example output

Hey Mike — quick reminder that invoice #1042 ($2,800) was due last week. Totally happy to send the link again if it got buried. Let me know if there's any holdup — thanks!
Frequently asked questions
How soon after the due date should I send the first reminder?▾
Day 1-2. The longer you wait, the harder it gets — and customers actually appreciate the prompt because invoices genuinely do get buried.
What if they still don't pay after 30 days?▾
Switch from email to a phone call. 90% of overdue payments resolve with one direct conversation. Written reminders only go so far.
Will this damage the customer relationship?▾
Not if the tone matches the situation. A friendly day-5 nudge keeps the relationship intact. Silence followed by a furious day-45 email is what damages relationships.
