Pricing & plans — how billing actually works
StableHow Atomic Apps AI bills you — tier comparison, what's included, overage rates, setup fees, annual discount, the founder-application program. Written for the buyer doing the math.
Last updated
Three tiers, an application-based founder program, transparent overage rates. No usage you didn't agree to. This page explains how every charge on your bill gets there.
The three tiers — what each one covers
Each tier raises three caps together: how many calls AIRIN answers, how many total minutes AIRIN talks, and how many post-call SMS messages we send. Bigger tiers also unlock features (24/7 coverage, real-time booking, more integrations) that smaller tiers don't carry.
| Tier | Monthly | Setup (one-time) | Calls / mo | Minutes / mo | Coverage | SMS follow-ups | Integrations |
|---|---|---|---|---|---|---|---|
| Starter | $179 | $299 | 120 | 250 | Business hours | — | — |
| Growth (most popular) | $449 | $899 | 350 | 650 | 24/7 | 250 / mo | 1 calendar |
| Enterprise | $999 | $1,499 | 1,000 | 1,800 | 24/7 | 1,000 / mo | 2 (calendar + CRM) |
The Growth tier is the one most operators land on — 24/7 coverage and real-time appointment booking are the two features that turn "captures every call" into "captures every booking."

How overages work — the math you actually need
If you exceed any cap on your tier, overage charges kick in at a per-unit rate. The rate is lower on bigger tiers (because we trust your volume signal, and because the marginal cost of one more call is lower at scale).
| Overage | Starter | Growth | Enterprise |
|---|---|---|---|
| Extra call beyond cap | $0.85 | $0.75 | $0.65 |
| Extra minute beyond cap | $0.50 | $0.45 | $0.40 |
| Extra SMS follow-up beyond cap | — (not included) | $0.06 | $0.05 |
A worked example. A Growth-tier ($449) HVAC business takes 420 calls in July averaging 2 minutes each (840 total minutes), and sends 280 SMS confirmations. Their July bill:
| Line | Amount |
|---|---|
| Growth monthly base | $449.00 |
| Overage — 70 extra calls × $0.75 | $52.50 |
| Overage — 190 extra minutes × $0.45 | $85.50 |
| Overage — 30 extra SMS × $0.06 | $1.80 |
| July total | $588.80 |
The dashboard shows live usage against caps, and we email you when you cross 80% of any cap so you can decide: stay on the tier and let overage bill, or upgrade. Upgrading mid-month is pro-rated, so there's no penalty for moving up at the right time.
What you're actually paying for
The line items on your bill, demystified:
| Line item | What it pays for |
|---|---|
| Monthly base | AIRIN's compute, telephony minutes, transcription, recording storage, dashboard, support |
| One-time setup fee | Your dedicated phone number, your dedicated AIRIN assistant build + tuning, FAQ import, greeting recording, transfer-rule configuration, 30-min kickoff call |
| Overage charges | Anything you used beyond your tier's caps, billed at the per-unit rates above |
| Add-on monthlies (optional) | Extra producers, extra locations, extra phone numbers, custom integrations — see add-ons below |
Setup fees are charged once at signup. Monthly base + overages bill on the first of each month for the prior month's usage. Annual customers prepay 12 months at the 10% discount.
Annual billing — the 10% discount
If you pay annually upfront, you get 10% off the monthly rate across all three tiers. The math:
| Tier | Monthly × 12 | Annual upfront | You save |
|---|---|---|---|
| Starter | $2,148 | $1,933 | $215 (≈ 1.2 months) |
| Growth | $5,388 | $4,849 | $539 (≈ 1.2 months) |
| Enterprise | $11,988 | $10,789 | $1,199 (≈ 1.2 months) |
Annual customers still pay setup as a one-time fee at signup, and any overages from the year true-up at renewal time.
Founder-customer program — application-based
This program replaces the prior "first-come, first-served price lock." It's now application-based because the cohort gets material benefits and we want to make sure the relationship is mutual.
What approved founders get
| Benefit | Detail |
|---|---|
| 25% off monthly base | Locked for 24 months from signature. Applies to the tier's monthly base; overage rates and add-on monthlies are NOT discounted (keeps margin intact when usage scales) |
| Up to waived setup fee | We may waive setup partially or fully on a case-by-case basis |
| Selected add-ons with no setup cost | Spanish, FNOL, and other add-ons may launch with no setup-fee component, case-by-case |
| Direct line to product | First read on new features; influence over roadmap priorities |
What we ask in exchange
| Ask | Detail |
|---|---|
| Testimonial consent | We can use you in a written quote on the marketing site |
| Case study consent | We can publish a short case study (you review before publish) |
| Regular product feedback | ~30-minute conversation every 6–8 weeks during the first year |
| Early-access beta testing | Try new AIRIN features 2–4 weeks before general availability and share what works/doesn't |
Spots + approval
- 20 approved customers per vertical (Insurance / HVAC / Plumbing — 60 total)
- Application-based — we reply to every application within 24 hours
- First-come, first-served by vertical — when a vertical hits 20, that vertical's program closes
- Lock survives cancellation in the sense that the 24-month rate stays — you don't get re-locked at the new price if you cancel and rejoin
Apply from any tier card on /pricing — the amber "Apply for founder pricing — 25% off" button under each plan.
Common add-ons
If a base tier doesn't fit your shape, add-ons fill the gaps:
| Add-on | Use it when… | Notes |
|---|---|---|
| Additional producer (metered) | You hire a second producer mid-tier | Bills only when the producer actually takes calls |
| Additional producer (unlimited) | The second producer takes daily volume | Flat monthly, no per-call meter |
| Additional location | You open a second physical location | Separate dashboard view; same AIRIN voice |
| Additional dedicated phone number | You want a separate AIRIN number for spam-control or a specific campaign | One-time provisioning + monthly carriage |
| Multi-language beyond English + Spanish | Vietnamese, Tagalog, Chinese, Portuguese | One-time setup fee; no monthly recurring |
For the full add-on list and current monthly rates, see /pricing.
What your tier guarantees beyond minutes
Every tier carries a service promise layer beyond the call/minute/SMS allowance. These are the boundaries that make pricing fair to everyone — clear caps + clear support levels + clear uptime guarantees.
Workflow components — what's actually configurable
A workflow component is any countable, configurable element that contributes to AIRIN's behavior beyond default product settings. Only Atomic Apps staff add components (after evaluating a customer request); customers don't add them directly. Examples:
| Element | Counts as |
|---|---|
| FAQ entry (Q + A pair) | 1 component |
| Transfer rule with conditions | 1 component |
| Booking type / service category | 1 component |
| Calendar / CRM integration trigger | 1 component |
| Custom tool / function | 2 components |
| Language variant beyond English + Spanish | 3 components |
| Per-technician / producer dispatch entry | 1 component per role |
| Custom out-of-hours rule beyond default after-hours | 1 component |
| Custom recording-disclosure language | 1 component |
Free defaults that don't count: greeting line · default business-hours toggle · per-state recording disclosure · default emergency-escalation rule · base AIRIN persona + voice.
Caps and pricing per tier
| Service guarantee | Starter | Growth | Enterprise |
|---|---|---|---|
| Workflow components included | Up to 10 | Up to 30 | Up to 75 |
| Each additional component / month | $19 | $15 | $11 |
| Assisted changes per month | 2 | 5 | 12 |
| Each additional assisted change | $79 | $59 | $39 |
| Engineering changes (custom integration, custom tool) | Quote only | Quote ($249+) | $149+ each |
| Support channels | Email + SMS | Email + SMS + scheduled call-back | |
| Response SLA — email | 48 business hours | 24 business hours | 8 business hours |
| Response SLA — SMS | n/a | Same business day | 2 business hours |
| Support hours | Mon–Fri 9–5 | Mon–Fri 9–5 | Mon–Sat 8–6 |
| Uptime SLA target | 99.5% (best-effort) | 99.9% | 99.95% |
| Downtime credit | None | 5% of monthly base per 0.1% under, cap 25% | 10% of monthly base per 0.1% under, cap 50% |
| Downtime fallback | Voicemail + SMS to owner | Forward to designated # + SMS notification | Forward + SMS + 1-min phone call to owner |
Uptime SLA important note: downtime caused by upstream providers (Vapi, Twilio, Anthropic outages on their side) is excluded from the SLA calculation per their respective SLAs. Our uptime promise covers what we control — the worker, your tenant configuration, your dashboard.
What's "self-serve" vs. needs a ticket
| Type | Examples | Customer can do it? |
|---|---|---|
| Self-serve | Edit greeting text · adjust hours · add FAQ Q&A · toggle voice persona · update transfer phone number · change SMS notification target | Yes — no ticket |
| Assisted change | Add a new transfer rule with conditions · add a new booking type · adjust dispatch logic · add a non-default integration trigger | Ticket required — counts toward monthly allowance |
| Engineering change | New custom integration · custom tool / function call · custom AIRIN behavior beyond standard workflow | Quote required — separate from monthly allowance |
The 2-day soft-launch review window at signup is your free correction period: any in-scope adjustment to the agreed plan during the first 2 days after go-live is free. After that, changes follow the tier allowance + per-change rate above.
What we don't charge for
A surprising number of features other vendors charge à la carte for, that we include in the base:
- Call recordings + transcripts (7-year retention default; 10-year extension available)
- Caller-ID lookup (name, phone metadata where carrier-available)
- Per-state recording disclosure (CA, FL, IL, MA, MT, NH, PA, WA — handled automatically)
- TCPA SMS consent capture (mandatory for any outbound SMS we send)
- Dashboard access for unlimited teammates within your tier
- Spanish language support (Growth + Enterprise)
- Emergency triage routing
- Daily SMS summary
We chose to include these because they're table-stakes for being legally compliant + operationally useful. Splitting them out would just complicate your bill.
What happens if you cancel
| Plan type | What happens |
|---|---|
| Month-to-month | Cancel anytime. Service ends at the end of the current billing cycle. No early-termination fee. |
| Annual | Cancel at renewal. The remaining months you prepaid still run through the end of the annual term. |
| Founder (any plan) | Same as above. You can cancel mid-lock; the lock simply terminates with the service. |
We keep your dashboard data + call recordings for the standard 7-year retention window even after cancellation, in case you come back or need to retrieve records for a compliance audit. After 7 years, data is permanently deleted.
Common questions
The FAQ section above is the canonical list (AI engines pull from it). Two things worth restating:
"Why is my bill higher this month?" Almost always overage — your call volume or minute volume went over your tier's cap. The Overview tab shows current-cycle usage at the top with a projected-overage banner if you're trending over. If volume is consistently above the cap, upgrading is cheaper than running on overage rates.
"Can I get a refund?" We don't issue refunds for past billed periods (the service was delivered). We do credit accounts for: documented service outages, billing errors on our side, and accidental double-charges. Email support with the invoice date and the issue.
