How to Collect an Unpaid Invoice From a Business in North Carolina: The Demand Letter and Your Options
Short Answer
Start with organized records and a clear written demand. A demand letter for a business debt should state who owes what, why, by when, and what you will do if it is not paid. If your contract or other evidence of the debt provides for attorneys' fees, G.S. 6-21.2 requires written notice giving the debtor five days from mailing to pay the outstanding balance without the fees.
Most contract claims must be filed within three years (G.S. 1-52(1)). North Carolina sets a $10,000 statutory ceiling for small-claims cases, but each county's local limit is between $5,000 and $10,000. Confirm the current limit with the clerk in the county where the case will be filed. An eligible claim may also be filed in district court.
Before You Write
Gather the contract or signed proposal, purchase orders, invoices, proof of delivery or completion, the payment history, and the emails or texts where the customer acknowledged the debt or raised complaints. Confirm the customer's exact legal name. If the customer is a company, search the Secretary of State's business registry so you name the right entity.
Then read your contract for terms that affect collection: interest or late charges, attorneys' fees, where disputes must be brought, any required notice or cure period, and any arbitration clause.
What the Demand Letter Should Say
- Who is writing and who owes the money, using correct legal names.
- The amount owed, broken down by invoice, with dates.
- The basis for the debt: the contract, the order, and what you delivered.
- Earlier requests for payment and any partial payments.
- A specific deadline and how to pay.
- What you intend to do if the balance is not paid, stated accurately.
Keep the tone factual and professional. A demand letter often becomes an exhibit later. A judge or magistrate may read it. Do not threaten action you do not intend to take or are not entitled to take.
Sending the Letter
Send the letter by a method you can prove, such as certified mail with a copy by email. Keep a copy of what you sent. The method matters: the attorneys' fee notice discussed below runs from the date of mailing. Send it to the address in your contract for notices, if there is one, and to the person who actually approves payments.
Interest
A lawful contract rate may govern. In a contract action, the amount awarded bears interest from the date of breach. After judgment, the contract rate applies only if the contract says that it applies after judgment; otherwise the legal rate applies. Different limits apply to credit extended for personal, family, household, or agricultural purposes.
If your contract does not set a rate, North Carolina's legal rate of interest is eight percent per year (G.S. 24-1). The rules on contract rates and interest from the date of breach are in G.S. 24-5(a).
Attorneys' Fees and the Five-Day Notice
North Carolina enforces an obligation to pay attorneys' fees on a note, conditional sale contract, or other evidence of indebtedness that is collected by or through an attorney after maturity, subject to limits in G.S. 6-21.2. A fee stated as a percentage of the outstanding balance is enforceable up to 15 percent. A promise to pay "reasonable attorneys' fees" with no percentage is construed as 15 percent of the outstanding balance (G.S. 6-21.2(1) and (2)).
There is a required notice. After maturity, the creditor or its attorney must notify the debtor that the fee provision will be enforced and that the debtor has five days from the mailing of the notice to pay the outstanding balance without the attorneys' fees. If the debtor pays in full within that time, the fee obligation is void (G.S. 6-21.2(5)). If your documents have no fee provision, this statute does not create one.
Business Debts and Consumer Debts Are Treated Differently
North Carolina's statute on prohibited acts by debt collectors applies to debts owed by a "consumer," meaning a natural person who incurred the debt for personal, family, household, or agricultural purposes (G.S. 75-50). A debt one business owes another for business purposes falls outside that definition. Collection conduct is still subject to other law, including North Carolina's general prohibition on unfair or deceptive acts or practices in or affecting commerce (G.S. 75-1.1). If you hire a third party to collect for you, know that North Carolina requires a permit to operate a collection agency (G.S. 58-70-1).
Do Not Let the Deadline Pass
An action on a contract generally must be brought within three years (G.S. 1-52(1)). For contracts for the sale of goods, the Uniform Commercial Code sets a four-year period, which the original agreement can shorten to not less than one year (G.S. 25-2-725(a)). Waiting while a customer promises to pay "next month" can cost you the claim.
If the Letter Does Not Work
- Negotiate a written payment plan that acknowledges the full balance and states what happens if a payment is missed.
- Small claims court before a magistrate is available for claims seeking money or specific property (G.S. 7A-210). North Carolina sets a $10,000 statutory ceiling for small-claims cases, but each county's local limit is between $5,000 and $10,000. Confirm the current limit with the clerk in the county where the case will be filed. An eligible claim may also be filed in district court.
- Claims above the county's small-claims limit and not exceeding $25,000 generally belong in district court. Claims exceeding $25,000 generally belong in superior court, subject to statutory exceptions and the rules for calculating the amount in controversy.
- A judgment is not the same as payment. Collecting on a judgment is a separate process.
Preventing the Next Unpaid Invoice
Most collection problems are easier to prevent than to fix. Written terms give you a stronger position before anything goes wrong. They can state payment deadlines, interest on late balances, an attorneys' fee provision, deposits or milestone payments, and, where appropriate, a personal guaranty from the owner of a small corporate customer.
