County Pricing Calculator

Why residents don't pay.
A life-safety alert is the wrong thing to charge residents for. Charging residents would force YANA-IGY to verify payment before sending a disaster alert, would create a consent-and-billing surface under TCPA/FCC that could delay an alert by seconds that matter, and would exclude exactly the residents who are most at risk. The county-paid model keeps delivery time constant regardless of a resident's financial status or billing state.

Why the fee is flat, not per-resident.
An SMS to 10,000 residents and an SMS to 100,000 residents cost nearly the same at the infrastructure layer once Twilio volume discounts apply. The engineering cost drivers are (1) the integrity pipeline — EID encryption, HGIP source verification, TFID gating, MSAD compliance, MIARP model auditing — which runs once per alert, not once per recipient; (2) continuous ingestion from USGS, NOAA, NWS, NASA FIRMS, and NDBC; and (3) Twilio SMS delivery, which scales with events per year, not subscribers. Tier pricing reflects the real cost curve rather than treating residents as line items.

What one annual fee covers.
Unlimited disaster alerts for that county's subscribers for the year, including all Twilio SMS fees; operation of the full detection / reasoning / integrity / delivery pipeline named above; Ripple Mesh Relay fallback when cellular is down; Vibe Text dual-sense accessibility delivery; and a per-alert audit record stored in Netlify Blobs that the county can pull for after-action review. No per-alert surcharges. No payment-processor markup — no Stripe in the path.

How pricing works:
Counties pay a flat annual fee based on population tier.
These prices cover multiple disasters per year including all Twilio SMS fees.
Small County (under 30,000): $5,999/year
Medium County (30,000–149,999): $11,999/year
Large County (150,000–499,999): $22,999/year
Mid-Metro (500,000–999,999): $39,999/year (negotiable $34,999–$49,999)
Extra Large / Metro (1,000,000–4,999,999): $69,999/year (negotiable $59,999–$79,999)
Mega Metro (5,000,000+): $300,000/year (negotiable $250,000–$400,000)
No Stripe. No third-party payment processor markup. 100% in-house, fair pricing.

Procurement notes.
YANA-IGY is a supplemental alerting service, not a replacement for WEA, EAS, or AMBER. Messages are alert-to-move only, enforced in code by MSAD; guidance, routing, and evacuation instructions are out of scope by design and cannot be turned on. The county receives: a subscriber-roster tool and an audit log for every alert sent. Research-backed justification for the detection methodology and the component-by-component architecture are maintained internally and available to authorized procurement reviewers on request.
