The plan

There's one. Every integration, every feature, every business — a complete build and a managed monthly, with nothing held back for a higher tier.

One plan

LinearZeta

$179/mo · no setup fee
14-day free trial · live in about two weeks · month-to-month $1,790/year — two months free

300 answered calls a month included, then $0.50 per answered call. Billed per call, not per minute — a longer conversation doesn't cost you more.

Any local service business that can't pick up while working and loses the booking when the phone rings out — a one-person shop or a full front desk.

A conversational voice agent built to answer every call. It handles your common questions, books appointments straight into the calendar you already run, and gets you the callback when a call needs you. Keep your own number or take a dedicated one we provide. No setup fee, no tiers.

Included

  • + Google Calendar — including multiple staff calendars
  • + Square Appointments — including per-staff booking (needs Square's own Plus plan or higher)
  • + Jobber — service requests written straight into your job software
  • + A Cal.com calendar we provision, if you don't run one of the above
  • + Alerts sent to you: callback requests emailed, and texted once you opt in — plus booking and cancellation emails you switch on (Google Calendar lines; Square sends its own)
  • + Returning-caller memory — regulars are recognized, and offered their usual once they've had a visit the agent booked
  • + Live emergency transfer — urgent calls reach you right away
  • + Every call graded, fixes shipped to everyone
  • + Your owner dashboard — every call, callback, and booking, what it was worth, and in time your new and returning customers

Not included

  • – A live human answering service
  • – Long-term contract or lock-in
  • – A setup fee

Also included

The fundamentals are never an upsell.

  • + Built to answer every call on the first ring, 24/7
  • + FAQs, hours, directions, and appointment booking — from your own information only
  • + Callers can find, reschedule, or cancel an appointment by phone — no booking number needed (a Jobber line takes a message instead)
  • + Switch on booking alerts on a Google Calendar line, and when a caller cancels an appointment your assistant booked, you hear about it right away — so a freed slot doesn't sit unnoticed
  • + After-hours and overflow call capture
  • + Human escalation for edge cases — the transfer path can't be removed
  • + A written summary of every call, searchable in your dashboard — plus a recap email after any month the agent booked something
  • + A monthly tuning and review call — we walk the graded calls with you
  • + Bring your own number, or we provide one — your choice
  • + Call-recording disclosure on every call — compliant even in all-party-consent states
  • + Pickup ordering for restaurants — priced off your own menu, paid at pickup

Run your practice on Clio Grow, or your studio on Mindbody? Available on request — we confirm fit on your call.

Start the trial with a card on file. Nothing is charged until day 15 — cancel before then and you pay nothing. If you keep it, billing starts on day 15 at $179 a month, month-to-month.

The trial is not a refund. Once billing starts, paid fees are non-refundable — but you're never locked in, and you can cancel before any renewal.

A straight answer on usage.

Your plan includes 300 answered calls a month. Go past it and each extra answered call is a flat $0.50, itemized on your invoice. Your dashboard shows the call count as the month runs, so the bill is never the first time you find out.

You're billed per answered call, not per minute — a longer conversation doesn't cost you more. A caller who needs six minutes costs you the same as one who needs two. Live answering services bill the other way: published overage rates run about $2.00 to $2.60 a minute, so one three-minute call costs $6 to $8 there, against $0.50 at most here.

Your number, your data, and your call recordings stay yours. There's no long-term contract: after launch you're month-to-month, and you can take an export and walk away whenever you like.

Pay annually, get two months free

Prefer to pay once a year? The annual plan runs for a 12-month term at ten months' price — two months free, same service.

  • Monthly$179/mo
  • Annual$1,790/yr

Our guarantee

  • If it isn't working and we can't fix it, cancel anytime — you're month-to-month. Formally: if the service materially fails and we don't restore it after you tell us, you can cancel for cause, whatever term you're on. That ends the term — fees already paid aren't refunded, and calls already answered are still billed.
  • No lock-in. Cancel before any renewal and you're done at the end of the paid period — your number, data, and recordings leave with you.
  • The annual plan simply locks in the lower rate for a 12-month term.

Taking food orders instead of appointments?

For a pizzeria or a quick-serve kitchen, the same plan runs a pickup-order line instead of a booking line. The agent walks the caller through your menu, handles sizes, crusts and toppings, and reads back an exact total.

That total is the part worth being picky about. It's calculated from your own menu prices by our system — not worked out by the AI, which is how a caller ends up quoted a number you never charged. Payment is at pickup, so no card details are ever spoken on the call. It doesn't need a POS system to work.

Pickup orders only — the agent doesn't take table reservations. Ask on your call audit and we'll walk your menu through it.

Stuck on a scheduler that won't connect?

Some booking systems keep their doors closed to everything else — including your own phone line. If yours is one of them, we offer a done-for-you switch to Square Appointments: we move your services, your staff schedules, and your client book, and your agent books into it from day one. Agent booking on Square needs its Plus plan or higher — a Square subscription in your name, separate from ours. The switch itself is a one-time service, priced by the size of your book — ask about it on your free call audit.

Common questions.

How much does it cost?

One plan: $179 a month, everything included. That covers 300 answered calls a month; past that, each extra answered call is a flat $0.50. There is no setup fee, no long-term contract, and nothing held back for a higher tier — every integration and every feature is in. Pay annually and it is $1,790 a year, two months free.

Is there a free trial?

Yes — 14 days free. You put a card on file and nothing is charged until day 15. Cancel before then and you pay nothing. The trial is not a refund: once billing starts, paid fees are non-refundable, and you stay month-to-month with no lock-in.

Do you bill by the minute?

No — by the call. You are billed per answered call, not per minute, so a longer conversation doesn't cost you more. A caller who needs six minutes costs you the same as one who needs two.

Do I need Square?

No. Google Calendar works on its own, including multiple staff calendars — the agent can book onto each staff member's own calendar. Square Appointments is supported if you already run Square Appointments Plus or higher, per-staff booking included. Don't run either? We set up and run a Cal.com calendar for you. All of it is included.

How does the AI voice agent work with my phone number?

Your choice: keep your existing business number — we connect it through Twilio with no number change, no new hardware, and no carrier switch — or have us provide a dedicated number, handy if you'd rather keep your personal line private. Either way, incoming calls are answered by your AI agent, anything it should not handle is routed to your team, and your phone system keeps working exactly as it does today.

Will it sound like a robot?

No. The agent uses natural, real-time ElevenLabs voice with sub-second responses. Callers have an ordinary conversation — they can interrupt, ask questions, and book an appointment without ever pressing a number.

What happens when a call needs a human?

The agent is bounded by design. It never invents a price, makes a promise on your behalf, or pushes past its limits — emergencies, complaints, and anything sensitive are routed straight to your team, and the escalation path is built into every agent and cannot be removed. We will tell you plainly during the call audit if your use case needs handling we do not offer yet.

Can it book into my Google Calendar?

Yes. You connect your Google Calendar during onboarding with a standard Google sign-in, and the agent reads your free and busy times to offer callers slots you are actually open, then writes the confirmed appointment onto that calendar — the caller gets Google's own confirmation email. It can book onto several staff members' calendars, so each person's appointments land with them. You can revoke access at any time from your Google Account permissions page.

Can it book into Square Appointments?

Yes, on Square Appointments Plus or higher — the agent books directly into the Square Appointments calendar you already run, per staff member. (Square's free plan doesn't let an outside app book on the business's behalf; upgrading is in your Square dashboard.) Not on Square yet? We also offer a done-for-you switch: we move your services, staff, and client book into Square Appointments and the agent books into it from day one — ask about it on your free call audit.

Can callers change or cancel an appointment by phone?

Yes, and they do not need a confirmation number. The agent looks their appointment up from the number they are calling on, reads it back to confirm it is the right one, then reschedules or cancels it in your calendar. On Square Appointments, that includes appointments booked online or at the front desk, as long as the booking is under the number they are calling from. A returning customer the agent has booked before is offered their usual service with their usual person when they call to book again. Included.

Can it take pickup food orders?

Yes. For a restaurant or pizzeria, the agent walks the caller through your menu, handles sizes, crusts and toppings, and reads back an exact total. The total is calculated by our system from your own menu prices, never guessed by the AI, so the number the caller hears is the number they pay. Payment is at pickup — no card details are ever taken on the call. It does not require a POS system, and it does not take reservations.

How do I know it is working?

You get your own dashboard, showing every call the agent answered and what came of it — searchable and filterable, with a written summary of each call. It also shows appointments booked against the average job value you set, callbacks still owed, and how many calls arrived after hours or while your line was busy. Once you have built up about two months of booking history, it also counts new customers (people booking with you for the first time through the agent) and returning customers (people who booked through it before and booked again). Callback requests land in a callback list you can mark contacted, a recap is emailed to you after any month the agent booked something, and we walk through it with you on a monthly tuning and review call.

How long until it is live?

About two weeks. We map how your calls should be handled, build and voice the agent, connect it to your number and calendar, test it against real scenarios, and launch.
