When to Use This Prompt

• An invoice is past due and you haven’t been paid
• You want a consistent follow-up process
• You need to be firm without damaging the relationship
• You’re tired of the awkward ‘hey, about that invoice…’ DMs

What You’ll Get

You’ll get a 4-email sequence: friendly reminder, professional follow-up, firm notice, and final warning. Each escalates in urgency while staying professional.

Why This Prompt Works

• Escalation path: Gives them multiple chances to pay before it gets serious

• Tone calibration: Early emails assume honest mistake; later emails assume avoidance

• Relationship preservation: Professional language maintains future business potential

• Clear consequences: Final notice states next steps without threats

How to Customize This Prompt

1. [DAYS OVERDUE] — Adjust email timing: small clients get more grace, enterprise gets stricter
2. [RELATIONSHIP] — New clients get friendlier tone; repeat late payers get firmer faster
3. [PAYMENT TERMS] — Net 30 vs Net 60 changes when you send reminders
4. [PROJECT STATUS] — If work is ongoing, mention pausing future work if needed

Pro Tips

• Send at due date: Don’t wait until it’s late; remind the day it’s due

• Make it easy: Include payment link, invoice PDF, and multiple payment options

• Phone call at 30 days: Email 4 should also be a phone call

• Learn from patterns: If the same clients are always late, adjust payment terms
