Sue for Unpaid Invoice in Pennsylvania Small Claims Court

When It Makes Sense to File

If a client owes you money, the invoice has aged past 60 or 90 days, and they are not responding to your reminders, Pennsylvania's Magisterial District Courts let you recover up to $12,000 without hiring a lawyer. The filing fees start at about $58 for claims under $500 and top out around $127 for claims between $4,001 and $12,000 — a fraction of what most attorneys would charge for even an initial consultation.

The four-year statute of limitations for contract claims under 42 Pa.C.S. § 5525 gives you a reasonable window, but filing sooner makes evidence fresher and collection easier.

Build Your Paper Trail

Before you file, gather everything that proves the debt:

• The original contract, proposal, or written agreement (even an email chain confirming the scope and price counts)
• The invoice itself, showing the amount, due date, and payment terms
• Proof of delivery — the work product, shipping confirmation, or client sign-off
• Communications showing the client acknowledged the debt or gave excuses for not paying
• A record of any partial payments already received

Print everything. Judges in Magisterial District Courts will not scroll through your phone.

Send a Demand Letter

Mail a formal demand letter via USPS Certified Mail with Return Receipt Requested. State the exact amount owed, reference the invoice number and date, and give 10 to 14 days to pay. Make clear that you will file a civil complaint if the deadline passes.

The demand letter is not legally required for contract claims, but it strengthens your case at the hearing. Judges view a plaintiff who tried to resolve the matter privately more favorably, and the certified mail receipt proves the defendant knew about the demand.

Identify the Defendant Correctly

This is where unpaid invoice claims go wrong most often. If your client is a sole proprietor doing business under a trade name, you must name the individual and the DBA — for example, "Jane Smith d/b/a Smith Marketing." If the client is an LLC or corporation, search the Pennsylvania Department of State Business Entity database at corporations.pa.gov to find the exact legal name and registered agent address.

Filing against "Smith Marketing" when the legal entity is "Smith Marketing Solutions LLC" can make the judgment unenforceable. Take five minutes to verify.

File the Civil Complaint

Fill out the AOPC Civil Complaint form (AOPC 308A) for Magisterial District Courts, or the Statement of Claim for Philadelphia Municipal Court. You are filing under "Assumpsit" — the category for contract and payment claims.

In the claim description, keep it factual: the date of the agreement, what you delivered, the invoice amount, the due date, and the fact that payment was not made. For a liquidated and ascertainable debt, or if your contract provides for it, you can claim pre-judgment interest at the statutory 6% annual rate under 41 P.S. § 202. State the legal basis, calculation method, and start date in the complaint.

File at the Magisterial District Court where the defendant lives or does business, or where the contract was performed. Bring the original complaint plus three copies per defendant, along with the filing fee.

Collect After You Win

If the judge enters a judgment in your favor and no appeal is filed within 30 days, but the client still does not pay, you can pursue collection. Options include execution writs against bank accounts and transferring the judgment transcript to the Court of Common Pleas to create a real-property lien.

The Pennsylvania small claims filing guide includes a damage itemization worksheet and a service tracking log to keep the paperwork organized from the demand letter through the hearing.
