Take an unpaid invoice to small claims court when the balance is large enough to justify your time, the customer is solvent and locatable, and you have a signed agreement plus a documented demand history. Filing is cheap and the hearing is fast, but winning gets you a judgment, which is permission to collect, not payment.
That last point is where most first-time filers get surprised. Small claims is genuinely accessible: modest fees, no pleadings, a hearing that usually runs fifteen minutes. The hard part sits on either side of it. Before the hearing, you need a record that proves the debt. After it, you need a plan for turning a piece of paper into money from a defendant who has already ignored you for months. What follows is general information for US businesses, not legal advice: rules, limits, and deadlines vary by state and change.
Can I sue a business for an unpaid invoice?
Yes. An unpaid invoice backed by a contract, purchase order, or accepted proposal is a straightforward breach of contract claim, and small claims courts hear them constantly. You sue the legal entity that owes you, at its correct legal name, in a court with jurisdiction over it, usually where the defendant is located or where the work was performed.
Two details decide more of these cases than anyone expects. First, name the right defendant. If your contract is with Riverside Fabrication LLC and you sue Riverside Fabrication Inc., or you sue the owner personally on a company debt, the case can be dismissed. Check the secretary of state registry for the exact entity name and the registered agent before you file.
Second, the amount you can claim is capped, and in a few states the cap is lower for business plaintiffs than for individuals. If your balance sits above the ceiling, you either waive the excess and stay in small claims (usually permitted, and often the right economic call) or file in a regular civil court, where you will want counsel and the cost profile changes completely.
What is the limit for small claims court?
It depends entirely on the state, and the spread is wide. Texas justice courts hear claims up to $20,000, while New York town and village courts stop at $3,000. Some states also apply a lower cap to corporate plaintiffs. Below are figures verified against official sources, but limits change, so check your own state court's current page.
| State | Limit | Notes |
|---|---|---|
| California | $12,500 individuals, $6,250 businesses | Corporations, LLCs, and other entities are capped at the lower figure (California Courts self-help). |
| Texas | $20,000 | Justice court small claims, one of the highest limits in the country (Texas State Law Library). |
| New York | $10,000 in New York City | $5,000 in city courts, $3,000 in town and village courts. Corporations and partnerships cannot sue in small claims and instead file in the commercial claims part, up to $10,000 in NYC. |
| Florida | $8,000 | Exclusive of costs, interest, and attorneys' fees, under Florida Small Claims Rule 7.010(b). |
Every other state sets its own number, and several have adjusted theirs recently. Treat any table you find online, including this one, as a starting point rather than a citation. The clerk's office in the county where you plan to file will confirm the current limit in a minute.
How much does it cost to file in small claims court?
Filing fees are modest almost everywhere, commonly in the $30 to $100 range, and they scale with the amount claimed in some states. California is a good published example: under Code of Civil Procedure section 116.230, the fee is $30 for demands of $1,500 or less, $50 from $1,500.01 to $5,000, and $75 above $5,000, rising to a flat $100 for parties filing more than twelve small claims in the state in twelve months.
Filing is not your only cost. Budget for service of process, which runs from a few dollars for certified mail to $75 or more for a process server or sheriff, and for your own time. Half a day of preparation plus half a day at the courthouse is realistic, and that is the expense that actually matters. On a $600 invoice, the math stops working before the filing fee is even relevant.
If you win, courts typically let you add the filing and service costs to the judgment, though again only if you can collect it.
Do I need a lawyer for small claims court?
Usually not, and in several states you are not allowed one. California bars attorneys from taking part in the conduct or defense of a small claims action under Code of Civil Procedure section 116.530, with narrow exceptions. Texas takes the opposite approach: Rule 500.4 of the Texas Rules of Civil Procedure permits attorney representation in justice court, though most parties still appear on their own.
The bigger question for a business is who shows up. Corporations generally cannot send just anyone. California requires a corporation to appear through a regular employee, officer, or director who was not hired or appointed solely to represent it in small claims court, under section 116.540. Other states have their own version of that rule, and New York sends business plaintiffs to the commercial claims part instead. Either way, send someone who actually knows the account, ideally whoever issued the invoices and sent the reminders.
What evidence do I need to win an unpaid invoice case?
You need to prove three things: an agreement existed, you performed, and you were not paid. In practice that means a signed contract, proposal, or purchase order, the invoice itself, proof of delivery or acceptance of the work, a statement of the account, and the full dated history of every reminder and demand you sent.
The paper trail carries more weight than any argument you make out loud. Judges in these hearings work a crowded docket, and the plaintiff who hands up a clean chronology tends to win quickly. A useful exhibit set:
- The agreement. Signed contract, accepted proposal, or the purchase order the customer issued, plus your written terms.
- The invoice. Dated, itemized, showing the due date and any late fee clause you actually agreed on in advance.
- Proof of performance. Delivery receipts, signed work orders, timesheets, an email where the customer says the job looked great.
- The ledger. Payments received, credits applied, the running balance. If your payment history lives in a bank feed or a spreadsheet, it is worth getting those transactions into your accounting software first, so the statement you hand the judge matches your books exactly.
- The follow-up record. Every reminder, every statement, the formal demand letter, and the dates each one went out.
That last item is the one businesses most often cannot produce, and it is the one that quietly decides close cases. A defendant who claims they never got the invoice, or that they were disputing the work all along, is much harder to believe when you can lay out eleven dated messages over ninety days and a signed delivery receipt. This is a strong argument for running follow-up through something that logs every message automatically rather than from a mailbox and a memory. When the sequence sends itself on a schedule and records what went out and when, the evidence file builds itself.
How long do I have to sue on an unpaid invoice?
Statutes of limitation on written contracts commonly run three to six years, but the exact period is set by state law and starts running from a specific event, usually the breach or the date the payment came due. California allows four years on a written contract under Code of Civil Procedure section 337. New York allows six on most contract claims. Oral agreements almost always get a shorter window than written ones.
Very few invoice disputes get anywhere near those deadlines, because the practical window closes much earlier. A two-year-old invoice is a weaker case in front of a judge than a ninety-day-old one, even when it is perfectly timely. Sitting on a debt looks like a debt you did not take seriously.
What happens if the business doesn't pay after I win?
Nothing automatic. A judgment is a court's finding that you are owed money, and it does not move a dollar by itself. If the defendant does not pay voluntarily, you go back to the court for enforcement tools: wage garnishment where it applies, a bank levy on the defendant's accounts, a lien on real property, or in some states a debtor's examination that forces the defendant to disclose assets under oath.
Each of those is a separate filing, with its own fee and its own information requirement. A bank levy is only useful if you know where the defendant banks. A lien only pays out if the defendant owns property and eventually sells or refinances it. Against a business that has closed or genuinely run out of money, none of it works, which is why the solvency question belongs at the start of the process rather than after you have paid the filing fee. Judgments do earn statutory interest and stay enforceable for years, so one against a company that recovers later is not worthless. Just do not count that money as collected.
Is small claims worth it for an unpaid invoice?
Run the arithmetic before you file. The rough test: the balance should be big enough that a day of your time plus fees is clearly worth it, the defendant should be an operating business with assets you can identify, and your documentation should be strong enough that the outcome is not really in doubt. Fail any of the three and the smarter move is usually a firm written escalation, a settlement at a discount, or a write-off.
Compare it to the alternative. A collection agency costs no filing fee and no day of your time, but contingency rates commonly run 25% to 50% of what they recover, and you hand over the customer relationship with the file. Small claims costs a hundred dollars and a morning, and you keep everything you collect. On a $9,000 invoice against a solvent local company, filing is often the better deal.
The best outcome, though, is not winning. It is not needing to file. A large share of small claims cases involving invoices settle once the defendant is served, because the filing is the first signal that the creditor is serious. You can often produce that signal for free, earlier, with a properly worded demand letter for payment that states the balance, the history, and a specific deadline. Before that, a disciplined overdue invoice email sequence resolves most of what would otherwise become a lawsuit.
If you invoice commercial customers regularly, systematize the pattern instead of improvising each time. Our guide to B2B debt collection covers the escalation ladder from first reminder to formal demand to filing. Consistent, logged follow-up is what keeps most accounts out of court, and it is exactly the record you need if one ends up there anyway.
This article is general information for US businesses, not legal advice. Small claims limits, fees, representation rules, and limitation periods vary by state and change over time. Confirm current requirements with the court where you intend to file, and consult an attorney in your state before relying on any of it.

- More on late fee on invoice: The late fee clause most small businesses rely on is unenforceable, for one boring reason. What you can charge, what caps it, and why charging it consistently matters more than the rate.
