Common plumber services to invoice
What to do when a client doesn't pay
Homeowners who promise to pay after the job but go silent once the water's running again. 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).

How do I handle late payments as a plumber?▾
Start with a polite reminder 1–3 days after the due date. If unpaid after 7 days, send a firmer follow-up. After 14+ days, consider a formal demand letter. Many plumbers bill upon completion.
