Small business in California
California's small businesses are as varied as its regions: restaurants and salons in Los Angeles, contractors and solar installers in the Inland Empire, dental and medical offices across Orange County and San Diego, tech-adjacent professional firms in the Bay Area, and agriculture and trucking services in the Central Valley. Many serve customers in Spanish as well as English.
According to the SBA Office of Advocacy's 2025 profile of California, the sectors with the most small employers are professional services such as law, accounting, engineering and consulting, health care, including medical, dental and therapy offices, construction and the trades, repair and personal services such as auto repair, salons and dry cleaners and restaurants, cafés and lodging.
Where Ava helps California businesses
- Recording-notice greetings. Because California requires all-party consent, Ava's greeting can include a clear recording notice when your setup records calls, along with her AI disclosure.
- Busy front desks. Salons, med spas and dental offices can send overflow calls to Ava for booking requests while staff stay with the client in front of them.
- Contractors across big metros. Plumbers, roofers and solar installers covering several counties can have Ava confirm the service area and capture job details.

An example call
Sunset Smile Dental (example) · Ava, AI receptionist
Hi, I chipped a tooth and want to come in this week
I'm sorry to hear that. I'm the office's AI assistant, and this call may be recorded. Are you a current patient?
Recording calls in California
All-party consent. California is an all-party consent state. Penal Code § 632 prohibits recording a confidential communication without the consent of all parties, and § 632.7 separately covers calls involving a cellular or cordless phone, whether or not the call is confidential. In Kearney v. Salomon Smith Barney (2006), the California Supreme Court applied California's rule to a call between California and a one-party state. If you record calls with California customers, tell callers at the start.
California businesses often get calls from Oregon, Nevada, Arizona and Washington. Of those, Oregon, Nevada and Washington require all-party consent or have unsettled rules, which is one more reason to give a notice at the start.
Ava always says she's an AI. If your setup records calls, the script we draft adds a short recording notice to her greeting, and you approve the wording. Interstate calls can be tricky; see the state-by-state overview.
Time zones and after-hours coverage
California runs on Pacific Time. We set Ava's business-hours and after-hours scripts to your local California time, so early-morning and late-night callers still reach someone.
