Late Payments & Collections
Dealing With Non-Paying Customers: A Practical Guide
Short answer
When a customer refuses to pay, stop chasing and start documenting. Send a formal demand letter, then choose between filing a mechanic's lien (if you did property work), hiring a collection agency, or filing in small-claims court — based on the dollar amount and your evidence.
There is a category of late payment that is different from forgetful or temporarily broke: the customer who has decided not to pay. The signals are unmistakable — they stop answering, dispute work scope after the fact, or claim a problem that was never mentioned. Once you recognize the pattern, your job changes from collections to evidence-building.
Distinguish 'late' from 'non-paying'
A late-paying customer eventually responds — they apologize, they promise a date, they pay something. A non-paying customer goes quiet, then resurfaces with a complaint after you push. The second pattern is a tell.
Once you identify a true non-payer, switch out of normal follow-up mode. Stop sending friendly reminders. Send one formal demand letter that documents the debt and your intent to escalate, then start preparing your case.
Document everything you already have
Before you spend a dollar on escalation, pull together the evidence package. Most small-claims judges and collection agencies want the same five things:
- The signed estimate or written approval of the work scope
- The signed work order, delivery receipt, or 'job complete' confirmation
- The invoice itself with the due date and terms
- Every email, text, and call log showing your follow-up attempts
- Photos or other proof that the work was actually performed
Pick the right escalation path
For property-related work (construction, landscaping, HVAC, plumbing, roofing), a mechanic's lien is usually your most powerful tool. Lien filing rules are strict and time-limited (commonly 60–120 days from last work date depending on state), but the lien attaches to the property and the customer cannot sell or refinance without paying you.
For service work that does not qualify for a lien, a collection agency is appropriate when you want to fully offload the recovery and accept losing 25–50%. Small-claims court is appropriate when you have strong documentation, the amount is above the agency break-even (usually $1,000+), and the customer is local.
If the customer is a business and the amount is significant ($10,000+), consult a small-business attorney before filing anywhere — the right venue and the right cause of action change your odds dramatically.
| Situation | Best path |
|---|---|
| Property work, under 90 days from last work | File a mechanic's lien (state-specific deadline) |
| Service work, $500–$5,000 | Collection agency |
| $1,000–$10,000 with signed paperwork | Small-claims court |
| Above $10,000 or B2B contract dispute | Consult an attorney first |
| Under $500 with weak documentation | Write off; improve estimate process for next customer |
Frequently asked questions
What is a mechanic's lien and who can file one?
A mechanic's lien is a legal claim against a property for unpaid work. Contractors, subcontractors, and material suppliers who improved real property can file one. Each state has strict filing deadlines, usually between 60 and 120 days from the last day of work.
Can I report a non-paying customer to credit bureaus?
Generally no — direct reporting to the major credit bureaus requires being a data furnisher and complying with the Fair Credit Reporting Act. Collection agencies can report on your behalf, which is one of the main leverage points they bring.
How long do I have to file in small-claims court?
The statute of limitations on a written contract is typically 4–6 years and on an oral agreement 2–4 years, depending on your state. Do not wait — evidence and memories degrade fast.
