Your business
never misses
a call again.

Mainline is the AI front desk employee that answers every call, books appointments, follows up after service, and brings customers back. Flat rate. No per-minute billing. Works 24/7.

The phone rings. You're on a job. The customer hangs up.

They don't leave a voicemail. They call the next business on Google. By the time you check your missed calls, that $800 job is gone. This happens to every service business, every single day. Mainline makes sure it never happens again.

Core difference

Full customer lifecycle

Other AI receptionists hang up and send you an email. Mainline manages the entire relationship from first call to fifth rebooking. That's the difference between an answering service and an employee.

Pricing

Flat rate, no surprises

No per-minute billing that punishes you for longer calls. One flat monthly price, unlimited calls. Predictable cost, predictable value.

Built for

Local service businesses

Plumbers, salons, contractors, clinics, auto shops. Mainline speaks your language because it was built specifically for businesses like yours, not enterprise call centers.

Intelligence

Gets smarter every week

Mainline learns your business. Your services, your pricing, your busy hours, your regulars. The longer it runs, the better it gets at being your front desk.

Every small business deserves a front desk that never sleeps.

Mainline exists so you can focus on the work you're great at, while every customer gets answered, booked, and taken care of.
