Sue for Unpaid Invoice New Jersey: Small Claims Court for Small Businesses

A client or customer owes you money and won't pay. If the amount is $5,000 or less, New Jersey small claims court gives you a way to collect without hiring a lawyer, spending months in formal litigation, or eating the loss. For freelancers, sole traders, and small businesses, this is often the most practical path to getting paid.

Check the Basics First

Your claim fits Small Claims if the unpaid amount (including any partial credits) is $5,000 or less. The statute of limitations for breach of contract and unpaid accounts is 6 years (N.J.S.A. 2A:14-1), so you have time — but don't sit on it. Evidence gets stale, businesses dissolve, and people move.

If the amount exceeds $5,000, you can either waive the excess to stay in the simpler Small Claims process (that waiver is permanent) or file in the Regular Special Civil Part for amounts up to $20,000.

Identify the Right Defendant

For unpaid invoice claims, the defendant is whoever agreed to pay — and getting the entity name wrong can make a judgment uncollectable.

• Individual customer: Sue by their full legal name.
• Sole proprietor: "Jane Smith d/b/a Smith's Boutique" — use the owner's personal name alongside the trade name.
• LLC or corporation: The exact registered entity name from the NJ Division of Revenue and Enterprise Services (DORES) database.

If the business changed its name or dissolved, DORES shows that too. An invoice addressed to "Smith's Shop" means nothing if the registered entity is "Smith Retail LLC."

Under Rule 1:21-1(a)(8), businesses can appear in Small Claims through an officer, partner, member, or full-time employee — they don't need a lawyer. But the representative needs written authorization from the entity.

Build Your Evidence

Unpaid invoice cases are straightforward when you have paper trail. Bring:

• The invoice(s) — Itemized, with dates, amounts, and terms
• The agreement — A signed contract, an email confirming the work and price, a purchase order, or even a text thread where the client agreed to the terms
• Proof of delivery — Delivery receipts, sign-off emails, project files with timestamps showing you completed the work
• Partial payment records — If they paid some but not all, bring the receipts showing what was paid and what remains
• Communication trail — Emails, texts, and letters where you requested payment and they either refused, made excuses, or went silent

Three copies of everything: judge, opposing party, yourself.

Send the Demand Letter

Before filing, send a written demand via certified mail. State the invoice number, the amount, and give 10-14 days to pay. Add that you'll file in small claims court if unpaid. This isn't legally required, but it's expected and it shows the judge you tried to resolve things first.

Keep the certified mail receipt and tracking information.

File and Serve

Form packet CN 10151. Filing fee: $50 + $10 mail service for one defendant. Submit through JEDS, by mail, or at the county courthouse. File where at least one defendant lives or does business; if no defendant resides or does business in New Jersey, file where the cause of action accrued.

If the defendant is a business entity, service may go to its registered agent, officer, director, or managing agent at the entity's business address. DORES lists the registered agent and address.

What Happens If They Don't Show

Default judgments are common in unpaid invoice cases because debtors often avoid court. If the defendant doesn't appear and service was valid, the court marks them in default — but you still present your evidence (the invoice, proof of delivery, payment history) so the judge can enter a specific dollar amount.

A judgment is just the first step. Collection — wage executions, bank levies, asset seizures — is a separate process. But having the judgment gives you legal authority to pursue those tools.
