When to use each follow-up tone

Days overdue	Recommended tone	Goal
1–7 days	Friendly reminder	Catch honest oversights
8–21 days	Polite but firm	Request confirmation and payment date
22–45 days	Firm	Create urgency with a clear ask
45+ days	Final notice	Signal escalation is next

What makes a good invoice follow-up email
