The Human Add AI pricing page lists three tiers, and the differences between them come down to three axes: how many inbound calls per month, how many physical or logical locations are routed by the same agent, and whether outbound calling is enabled. Starter at $497 monthly handles up to 250 inbound calls, a single location, and inbound only. That works for the smallest single-truck operations, solo professionals, and any operator who wants to pilot the platform before scaling.
Professional at $997 monthly is where most service-business operators end up. The 750-call ceiling is generous for any single-location business with normal inbound volume, the multi-location routing lets a business with two or three offices share a single agent with location-aware booking, and the deeper CRM integration matrix removes the manual hand-off step between the receptionist and the field-service software. Professional is also the tier where the SLA tightens on the response-time guarantees and on the build-tuning cadence after launch.
Enterprise at $1,997 monthly is for high-volume operators who want unlimited calls without watching a meter, white-label phone numbers, a named tuning contact at Human Add AI, and the outbound module. Outbound calls billed at fourteen cents per minute give the platform missed-call callback, appointment reminder, lead-nurture, and review-collection use cases. The outbound meter is visible in the dashboard with a hard-cap option for any operator who wants to bound monthly spend.
Across all three tiers, the conversation quality, the booking automation, the CRM sync, the SMS lead alerts, the call recording with searchable transcripts, the dashboard, and the support team are identical. The platform is engineered so a Starter customer should never feel like they are using a worse product, only a smaller-volume version of the same product.
Common questions from service business operators
What does the caller actually hear when they dial my line?
The caller hears a custom greeting in the voice you picked during onboarding (warm, professional, or fast), followed by the agent asking how it can help. The conversation flows naturally, not as a menu tree. The agent introduces itself as part of your team on Starter and Professional plans, and uses your business name as the caller-facing identity on the Enterprise white-label tier. There is no holding music, no "press 1 for sales", and no robotic cadence.
How does the booking calendar integration handle conflicts?
The agent reads live availability against your calendar in real time, which means it never offers a slot that is already taken. If the calendar update happens between the moment the agent reads availability and the moment it confirms the booking (the rare race condition), the platform's conflict handler reverts the booking, texts the operator with both calls, and lets the operator decide which one keeps the slot. In practice this happens roughly once per ten thousand bookings.
What integrations exist for sending the lead summary to my CRM?
Native integrations cover Jobber, Housecall Pro, ServiceTitan, FieldEdge, mHelpDesk, Workiz, RazorSync, ServiceM8 in the field-service world, Salesforce, HubSpot, Pipedrive, Zoho, Close, Copper in the horizontal CRM world, Clio Manage, Lawmatics, Lawyaw, MyCase, Practice Panther, Smokeball in legal, Dentrix Ascend, Open Dental, Eaglesoft, Curve Dental in dental, and twenty other vertical-specific systems. Webhook handoffs cover everything else.
How does the platform handle emergency calls?
Emergency triage is configured during onboarding. The agent recognizes emergency signals in the caller's wording (specific keywords for the vertical, urgency tone, and explicit "this is an emergency" statements), routes the call directly to the on-call dispatcher number, and sends a high-priority SMS in parallel so the dispatcher can see the lead even if they miss the call. The emergency routing happens within the same call (no callback delay), which is critical for service business operators where the first business to answer wins the job.
What does the dashboard show?
The dashboard surfaces every inbound call (with searchable transcripts and recorded MP3), every booking, every SMS lead alert, the recovered-revenue math against your reported average ticket size, the conversion rate from call to booked appointment, the agent's confidence score per call, and the weekly summary email metrics. Operators on Professional and Enterprise also see the multi-location split and the outbound-call meter.
What is the SLA on agent tuning if something needs to change?
Standard tuning requests (script edits, new intake questions, calendar rule changes) are turned around inside 24 business hours on Starter, inside 8 business hours on Professional, and same-business-day on Enterprise. Operators can also self-serve most edits through the dashboard's knowledge base section, which propagates to the live agent within minutes.
How do I know it is actually working?
The weekly summary email shows the count of inbound calls, the count of bookings, the count of SMS lead alerts, the count of qualified leads texted to the dispatcher, and the recovered-revenue math based on the average ticket size reported during onboarding. The dashboard also has a "before / after" comparison view that runs against historical voicemail patterns if the operator imports them, so the lift is visible in dollar terms not just call counts.
Can I try it before committing?
Yes. The public demo line at (617) 812-5251 runs the production agent for a generic service business. Call from any phone and run a real scenario (an actual customer question, an actual scheduling constraint, an actual edge case). The agent will answer, qualify, and offer a real booking slot. The demo gives a faithful preview of what your own customers would experience. No signup, no form, no email collection on the demo path.
What changes after the first month on the platform
After thirty days on Human Add AI, three things have changed for the typical operator. First, the recovered-revenue math has compounded into a concrete dollar number that the operator can see in the dashboard and in the bank account. For most single-location service businesses, the first-month recovered revenue lands between $6,000 and $25,000, against a $497 to $997 plan cost. The platform has paid for itself many times over, and the operator mental model has shifted from "evaluating a new vendor" to "operating a critical revenue tool".
Second, the agent has been tuned to the specific cadence of the business. Tuning continues forever (every business evolves, every season brings new call patterns, every new service line needs new intake questions), but the bulk of the agent customization is done in the first 30 days. After that, the operator can edit the knowledge base from the dashboard for most changes and only needs to ping the Human Add AI team for the larger script revisions.
Third, the operator has started thinking about the second-order use cases the platform unlocks. Outbound missed-call callback usually goes live in month two for operators on Professional or Enterprise. Appointment reminder calls usually go live in month three. By month four, the platform is doing both inbound and outbound work that previously required either a part-time staffer or a separate scheduling service, and the operator is running a tighter business with the same overhead.
What the platform looks like a year in
The shape of Human Add AI on month twelve looks different from month one in a few specific ways. The agent has been tuned through dozens of small adjustments, each one shaped by a real call that was almost-perfect-but-not-quite. The CRM integration has been used long enough that the operator has cleaned up the data flow on their end, which means the lead summaries are landing in the right pipeline with the right tags. The outbound module (if enabled) has settled into a daily cadence that the operator runs without thinking about it.
The recovered-revenue number has also gone from a launch-week curiosity to a baseline expectation. Most operators stop tracking it as a single metric and start treating it as part of normal revenue. The platform shows up as a $497 to $1,997 line item in the monthly operating budget and quietly returns 10 to 30 times that in recovered bookings, the same way a good lead-acquisition channel does.
The one thing that almost never changes is the support cadence. The Human Add AI team continues to answer questions inside the SLA, continues to push tuning updates when the operator asks, and continues to send the weekly summary email every Monday. The platform is built to be set-it-and-forget-it, but the team is built to be available the moment the operator needs them.
What the operator sees on a typical Monday
The weekly summary email arrives Monday morning at 7 a.m. local time. It is one screen of plain-language metrics: how many calls came in last week, how many were answered (almost always 100 percent), how many resulted in a booked appointment, how many qualified as emergency-routed to the on-call dispatcher, the dollar value of recovered missed-call revenue based on the average ticket size, and a comparison against the previous four weeks.
For most operators that email is enough. The operator scans it for any anomaly (a sudden drop in bookings, an unusually high emergency rate, a spike in after-hours calls) and either responds to the anomaly or moves on with the rest of the Monday. The dashboard sits behind the email for any deeper investigation: drilling into a specific call, listening to the recorded conversation, reading the transcript, reviewing the agent confidence score on a particular interaction, or tuning a specific intake question.
The Monday email also surfaces the outbound activity for operators on Professional and Enterprise: how many missed-call callbacks fired, how many connected, how many appointments came out of the callbacks, and the same metric for appointment reminders and review-collection calls. The outbound numbers usually drive the second-order conversation between the operator and the Human Add AI team: should we expand the outbound use cases, should we adjust the callback timing window, should we change the appointment-reminder script.
