Common hvac technician services to invoice
What to do when a client doesn't pay
Seasonal rush jobs where the client is grateful in August but forgetful in October. Sound familiar? Here's a simple escalation plan:
Day 1–3: Friendly reminder
A polite email referencing the invoice number and amount. Most clients pay after this.
Day 7–14: Firmer follow-up
Mention the late fee clause in your terms. Reference the original due date.
Day 30+: Final notice
State the total with accrued late fees. Mention next steps (collections, lien, small claims).
