A customer is calling.

Mainline picks up on the first ring.

24/7 Answers your business line
Every call Details captured automatically
One email Clean summary after the call

Your customers don't wait for you to call back.

You're under a sink, driving to a job, or it's 11pm, and someone else's pipe just burst. If nobody answers, they call the next plumber on the list.

Busy

You're already on a job

Both hands are full and the phone's going to voicemail, again.

After hours

The call comes in at 11pm

Nobody's picking up outside business hours, but emergencies don't check the clock.

No follow-up

The voicemail sits there

By the time you call back, they've already booked with someone else.

Forward the number. That’s the setup.

You forward your business line, and Mainline does the rest. Every call, every time.

Answers

The AI answers

A caller reaches your business line and is greeted immediately, no hold music, no voicemail. It asks the same questions your best receptionist would.

Captures

Details get captured

Name, callback number, address, and a description of the problem, all pulled from the conversation and logged automatically.

Notifies

You get notified

An email lands in your inbox the moment the call ends, with everything you need to call the customer back and get the job scheduled.

One clean summary. Not a voicemail to sit through.

Full transcript, every time

Nothing gets lost between what the customer said and what you see.

Emergencies flagged instantly

Burst pipes, flooding, and gas leaks get a different subject line, so you know before you open it.

Nothing to log in yourself

No app to check, no dashboard to remember. It's already in your email.

Some calls can't wait for Monday.

Mainline listens for the words that mean trouble: flooding, a burst pipe, a gas leak. Then it changes what happens next.

  • The AI recognizes the emergency mid-conversation, not after the fact.
  • It skips the full intake and gets straight to a name and a callback number.
  • You get a separate, unmistakable alert, not buried in a normal inbox.

You're elbow-deep in someone's pipes. Mainline is answering the next call.

You didn't get into plumbing to sit by the phone. Mainline handles the part of the job that pulls you away from the job, so the next customer gets a real answer instead of a ring that goes nowhere.

Set up around your call volume.

Every plumbing business is different.

Some take five calls a week, some take fifty. Rather than guess at a number that doesn't fit you, pricing gets set up on a quick call based on how your business actually runs.
