The Late Payment Policy + 4 email scripts that turn 90-day-overdue invoices into 14-day-paid invoices
Short summary
A systematic late-payment framework using three components—professional invoices with bold due dates, a disclosed late-payment policy (1.5%/month fee, work suspension at 30 days, cost-recovery clause), and four scheduled email escalations (Days 0, 7, 30, 60)—turns ad-hoc payment delays into predictable 14-day collections. Work-suspension triggers behavior change more effectively than late fees alone.
- •Three-piece system: professional invoice format, disclosed late-payment policy, scheduled email escalation cadence
- •Four-stage email escalation (Days 0, 7, 30, 60) calibrates tone from friendly reminder to collections referral and termination
- •Work-suspension at 30 days overdue is the key behavioral lever; late fees alone don't motivate client payment
