B2B Debt Collection Laws in California

Overview

California B2B Debt Collection Rules

California is the largest commercial market in the US, with over 4 million registered businesses. Collecting unpaid B2B invoices here requires understanding both state and federal regulations — even though many consumer-focused laws (like FDCPA) don't directly apply to commercial debts.

Key distinction: The federal FDCPA does not apply to B2B debts. However, California's Rosenthal Act has been interpreted by some courts to extend to small business debts. Best practice is to maintain professional collection standards regardless.

Statute of Limitations

How Long You Have to Collect

California Code of Civil Procedure

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	4 years	CCP §337
Oral contract	2 years	CCP §339
Open book account (invoices)	4 years	CCP §337
Account stated	4 years	CCP §337
Promissory note	4 years	CCP §337

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 can restart the clock.

Key Regulations

Laws That Apply to B2B Collections

Commercial reasonableness standard applies

California Prompt Payment Act

Applies to certain commercial transactions and government contracts. Sets timelines for payment and penalties for late payment.

State/local government contracts: payment within 45 days
Late payment penalty: 10% of the invoice amount or $20,000 max
Construction contracts have specific retention and payment rules

Rosenthal Act — Limited B2B Application
