Work out what your calls really cost, what the ones you miss are worth, and how many people or AI agents you need to answer them. Every assumption is visible and editable.
Compare what a bundled voice AI vendor charges per minute against the real cost of running on your own Twilio and OpenAI accounts plus a flat platform fee. Includes human minutes, which bundled vendors meter and we do not.
Compare per-minute costPut a number on the calls that ring out. Enter your daily call volume, how many go unanswered, and what a new customer is worth, and see the monthly and yearly revenue walking out the door.
See what missed calls costModel an AI receptionist against your real call volume: hours of staff time saved, after-hours bookings recovered, what the AI costs to run on your own keys, and how quickly it pays back.
Calculate ROIThe classic Erlang C staffing model: calls per hour, handling time, service-level target and shrinkage in, agents required out. Then slide the share of calls an AI agent handles and watch the headcount change.
Work out staffingClinics, dental practices, trades, salons, restaurants and estate agents who suspect they are losing bookings to voicemail and want a number before they act.
People sizing a team, setting a service-level target, or building the case for an AI agent to take first-line calls so humans can take the hard ones.
