Collecting unpaid bills in Pennsylvania comes with a specific set of local rules. The biggest surprise for most business owners is Pennsylvania’s Fair Credit Extension Uniformity Act (FCEUA). This state law says that in-house billing departments and business owners must follow the exact same fair-treatment rules as outside collection agencies.

Whether you run a medical clinic, a trade supply company, or a professional practice, staying within PA state laws helps you protect your revenue while treating clients fairly.
Quick Summary: How Debt Collection Works in Pennsylvania
-
Original Creditor Rules: You must follow fair contact rules, even if you are collecting your own bills in-house.
-
4-Year Legal Deadline: You generally have 4 years from the date a bill becomes past due to take legal action.
-
6% Interest Cap: You cannot charge more than 6% annual interest on overdue balances unless your original contract states a different rate.
-
Construction Liens: Contractors and suppliers have 6 months to file a mechanics’ lien on unpaid projects.
4 Main Rules Every PA Business Needs to Know
1. In-House Billing Staff Must Follow Fair Rules
Under Pennsylvania law (FCEUA), your own office staff cannot use aggressive, deceptive, or harassing tactics. You are held to the same high standards as an outside agency. This means no calls before 8:00 AM or after 9:00 PM, no calling a customer at work if their employer forbids it, and no misleading threats.
2. The 4-Year Clock (Statute of Limitations)
Pennsylvania puts a strict 4-year limit on taking legal action for unpaid invoices, written contracts, and open business accounts.
⚠️ Important Note: Accepting a small partial payment or a new signed payment promise from a customer can restart this 4-year clock. Always get agreements in writing.
3. The 6% Interest Limit
If your original contract or invoice terms do not explicitly mention a specific late fee or interest rate, Pennsylvania caps your legal pre-judgment interest at 6% per year. You cannot add high surprise late fees after the fact unless the customer agreed to them upfront.
4. Special Rules for Contractors (Mechanics’ Liens)
If you provide labor or materials on a construction project in Pennsylvania, you have powerful rights—but tight deadlines:
-
Give 30 Days’ Notice: Subcontractors must give a formal 30-day notice before filing a lien.
-
6-Month Cutoff: You must formally file your mechanics’ lien within 6 months of finishing your work.

Frequently Asked Questions
Do out-of-state collection agencies need a special license in Pennsylvania?

Can I charge collection fees to the customer in Pennsylvania?
You can only add collection fees or attorney fees to a customer’s balance if your original signed agreement or contract explicitly allows it.
What are the rules for medical bills in Pennsylvania?
