The phone line, answered
The calls a San Mateo business misses
“Electrician san mateo” draws 170 searches a month, and a search that becomes a call goes to the company that picks up. A managed AI receptionist from Lithium Marketing answers using your services, hours and service area, all loaded before the first real call, so the line gets picked up at 2 p.m. and at 2 a.m. The same team builds custom automation and offers AI consulting for San Mateo service businesses.
After-hours calls are the ones that can go to voicemail. Water damage restoration searches naming San Mateo run 20 a month, and a click on one averages $13.11. A call that rings out at 9 p.m. can be a job somebody else books. San Mateo County counts 233 plumbing and HVAC contractors, which is a long list of other numbers for a caller with a burst pipe.

The San Mateo market
Who is on the other end of the call
49.9% of San Mateo’s occupied homes belong to the people who live in them. For a rental address, the receptionist can ask who owns the property before it books anything, which keeps the appointment with the person who can approve the work.
San Mateo packs 8,528 people into each square mile, so a service area that covers the city holds a lot of homes. The receptionist takes the address, checks it against the service area you loaded and books the opening that fits, and a call from Burlingame or Belmont reaches the same line.

Trades in San Mateo County
Repair calls and project calls need different rules
Two kinds of call reach a San Mateo contractor. One needs somebody today, and the other is an estimate on work planned weeks out. San Mateo County’s 42 excavation and site preparation contractors and 214 new home builders take the second kind, so their calls should book an estimate, capture the project type and reach a person only when the job is big enough.
The first kind is a burst pipe, a dead furnace or a garage door that will not close. Those calls need a yes or no on whether somebody can come out today, and the receptionist answers from the hours and service area you set, then books or transfers. The rules differ by trade, and they get approved before the line goes live.

Set up for you
From a rule list to a tested line
The order is rules, then answers, then connections, then a test call from your own phone.
Decide who gets a person
Emergencies, existing customers and anyone who asks are the usual transfers. Everything else can be booked, answered or followed up by text.
Load the answers callers hear
We load the services, hours, service area and the questions your callers repeat, written the way your team says them.
Wire the calendar and the handoffs
Once the calendar connection is checked, bookings land in the tool you already use. Transfers go to whichever numbers you list.
Call it yourself before anyone else
You ring the line, hear how it handles a real question, then read the recordings and change what did not sound right.

Proof
The AI on two real phone lines
A plumbing company was losing after-hours emergency calls to voicemail, and Lithium built it a custom AI phone system to answer them. For Smart Doors LLC, a garage door company, Lithium built the website first, then added the AI receptionist for its incoming calls.

FAQ
What to ask before an AI answers your phone
Still curious?
Call (503) 766-5964 or email [email protected].
What happens when a caller asks for a person?
It goes to the number you nominate. Lithium sets the transfer rules with you, so an emergency, an existing customer or anyone who asks for a human reaches a human, while the rest of the calls get answered and booked.
Is there a setup fee or a contract?
There is no contract and no setup fee, and the $179 a month covers the managed receptionist. The service can stop whenever you want, and you approve the call rules and transfer numbers before the line goes live.
How quickly can it answer a real call?
The answer is days, not weeks. Once the rules, the knowledge base and the calendar access are in place, you call the line yourself and listen before it takes a real call.
How does it handle an emergency?
It follows the transfer rule you set. An emergency can go straight to the number you nominate, and everything else gets the address, the details and the next opening on the calendar.
Which administrative tasks can be automated?
Follow-up is where the repetition sits: CRM notes, texts to a caller who has not booked, review requests and documents that need filing. Custom automation starts with a free call about that workflow and usually lands in one to two weeks; Lithium also offers AI consulting on where the tools fit before anything is built.
