Illinois B2B Debt Collection Rules
Illinois is the third-largest state economy in the US, home to major financial, manufacturing, and technology sectors centered around Chicago. Collecting unpaid B2B invoices here requires compliance with the Illinois Collection Agency Act (ILCA) and associated IDFPR regulations.
Key distinction: Illinois has one of the longest written contract SOLs in the nation at 10 years. The federal FDCPA does not apply to B2B debts, but Illinois collectors must avoid practices that violate state law. The Illinois Consumer Fraud and Deceptive Business Practices Act has limited B2B reach but deceptive commercial practices remain actionable.
How Long You Have to Collect
Illinois Code of Civil Procedure — Limitations
The statute of limitations determines how long a creditor has to file a lawsuit to collect a debt. Once expired, the debt is not forgiven — but it becomes unenforceable through the courts.
| Contract Type | Time Limit | Code Section |
|---|---|---|
| Written contract | 10 years | 735 ILCS 5/13-206 |
| Oral contract | 5 years | 735 ILCS 5/13-205 |
| Open account (invoices) | 5 years | 735 ILCS 5/13-205 |
| Account stated | 5 years | 735 ILCS 5/13-205 |
| Promissory note | 10 years | 735 ILCS 5/13-206 |
Important: The clock starts from the date of the last activity on the account — typically the last payment or the invoice due date. A partial payment or written acknowledgment can restart the clock.
Who Needs a License
Illinois Collection Agency Act (IDFPR)
Illinois requires third-party debt collectors to be licensed under the Illinois Collection Agency Act, regulated by the Illinois Department of Financial and Professional Regulation (IDFPR).
- Third-party collectors (agencies, law firms collecting for others) must hold an IDFPR Collection Agency license
- Original creditors collecting their own debts do not need a license
- Attorneys collecting debts on behalf of clients must be licensed as a collection agency or comply with attorney-specific exemptions
- License requires application, background check, surety bond, and IDFPR approval
- Annual renewal required with IDFPR

Laws That Apply to B2B Collections
UCC Article 2 — Commercial Transactions
The Uniform Commercial Code governs most B2B transactions in Illinois. Unlike consumer protection laws, UCC assumes both parties are sophisticated commercial entities.
- Governs sale of goods between businesses
- Allows contractual modification of remedies and limitations
- Permits higher interest rates than consumer transactions
- Commercial reasonableness standard applies
Illinois Consumer Fraud and Deceptive Business Practices Act
While primarily a consumer protection statute, the Illinois Consumer Fraud Act (815 ILCS 505) has been applied by courts in certain B2B contexts, particularly where one party is a small business.
- Deceptive representations about debt amount, nature, or legal status prohibited
- False threats of legal action not intended violate state law
- Illinois AG can investigate commercial deception complaints
- Private right of action available in some circumstances
Illinois Interest Act
Commercial interest rates in Illinois are governed by the Illinois Interest Act (815 ILCS 205). Businesses have more flexibility than consumer contracts.
- Parties may contract for any interest rate in commercial agreements
- Default legal rate: 5% per year where no rate is specified
- Post-judgment interest accrues at the statutory rate set by the court
- Attorney fees recoverable if provided for in contract
