Debt collection agency in California: a small business guide
To hire a debt collection agency in California for an unpaid business invoice, first confirm whether your debtor is a company or a person. California’s licensing law is aimed at consumer debt. Then check your filing deadline (four years on a written contract). Compare contingency terms, and get matched with a collection partner that works California accounts.
What a debt collection agency in California does for a small business
A collection agency takes over an unpaid account after your own reminders stop working. It contacts the customer in its own name and locates businesses that have moved or gone quiet. It negotiates payment or a plan you approve. If suit makes sense, it can refer the account to a California attorney. Most work on contingency, so the fee comes out of what is recovered. See how a collection agency works.
California licensing rules for business debts
California’s Debt Collection Licensing Act requires a license from the Department of Financial Protection and Innovation to collect consumer debt. The statute says it does not apply to covered commercial debt[source]. That doesn’t mean business debts are unregulated. The Rosenthal Act’s fair-collection rules were extended to covered commercial debt owed by natural persons, such as sole proprietors and personal guarantors. This applies to debts entered into, renewed, sold or assigned on or after July 1, 2025[source]. If your debtor is an individual or a guarantor, ask your collection partner how it handles those rules.
California filing deadlines for unpaid invoices
| Type of claim | Deadline to sue in California |
|---|---|
| Written contract | 4 years from the breach (Code Civ. Proc. § 337) |
| Oral contract | 2 years from the breach (Code Civ. Proc. § 339) |
| Sale of goods | 4 years (Cal. Com. Code § 2725) |

Small claims court or a debt collection agency in California?
California small claims court is inexpensive and quick, but it has limits. A business can generally sue for no more than $6,250. Lawyers can’t represent you at the hearing. And the court doesn’t collect the money for you if you win[source]. For larger balances, customers who have gone silent, or debtors outside California, an agency or collection attorney is usually the better fit. Compare the options in small claims vs. collection agency.
Collecting from a California customer when you’re in another state
You can place a California account from anywhere. What matters is that your partner can reach the customer and, if needed, work with counsel in the right California county. See out-of-state customer collections.
How to choose a collection partner for a California customer
- Experience collecting from businesses, not just consumers
- Any license or registration the work requires (ask, then verify with the regulator)
- Contingency rate, minimums and any fees in a written agreement; see collection agency fees
- Attorney contacts in California if suit or judgment enforcement becomes necessary
- Trust-account handling and a regular remittance and reporting schedule

Frequently asked questions
Does a collection agency need a California license to collect a business debt?
California’s Debt Collection Licensing Act is aimed at consumer debt. It says it does not apply to covered commercial debt. Agencies that also collect consumer accounts or debts owed by individuals may hold a DFPI license. Ask, and verify it with the DFPI.
How long do I have to sue a California customer for an unpaid invoice?
Generally 4 years on a written contract and 2 years on an oral contract, with 4 years for sales of goods. The clock usually starts when the payment was missed.
What does a debt collection agency in California charge?
Most charge a contingency percentage of what they recover. Rates rise for older or smaller accounts. Some offer flat-fee letter programs for newer invoices. Get the rate and any minimums in writing.
Can my business use California small claims court instead?
Yes, for claims up to $6,250 for a business. You represent yourself, and if you win you still have to collect the judgment.
