RouteGenie is NEMT software built for non-emergency medical transportation operations that have outgrown basic dispatch software. It combines NEMT scheduling software, dispatch, routing, billing and fleet compliance in one platform, running 600+ fleets and 20,000+ vehicles across 46 states and two countries at roughly 50,000 trips a day. NEMT dispatch software built for multi-site scale. Operators run every location in one instance with role-based access, per-location configuration and a complete audit trail on every trip change — who cancelled a trip, when, and why. DispatchGenie builds and continuously re-optimizes routes with native multiload, so a 200-vehicle schedule rebuilds in seconds instead of being maintained by hand. Subcontractor vehicles appear on the same live map as owned fleet, which matters when your network is larger than your payroll. NEMT broker software, built in. ImportGenie runs 28 live broker and payer integrations — ModivCare, MTM, Veyo, Verida, SafeRide Health, Alivi, VectorCare, New York MAS, Uber Health, transit authorities and Medicaid health plans — importing trips and returning statuses automatically, with no re-keying. BillingGenie is full non-emergency medical transportation billing software: Medicaid billing, CMS 1500, broker billing, claim scrubbing and denial management in the same system, so billing is not a second platform. Enterprise administration. SAML2 single sign-on with Microsoft Entra ID, Okta, OneLogin and Google Workspace. Single-tenant deployment with per-customer data isolation. SOC 2 Type 1 attested. HIPAA-aligned controls, BAAs, encryption in transit and at rest, role-based permissions, and four portals: staff, drivers, payers and facilities, and passengers. Open REST API. Pricing that does not punish growth. Flat per-vehicle pricing with unlimited trips and unlimited users. No per-trip fees, no per-seat licensing. Cost tracks your fleet, not your trip volume or headcount — which is why high-volume operators and large agencies model lower total cost here than on per-trip or per-user platforms. RouteGenie serves large and mid-size NEMT providers, PACE organizations, adult day programs, regional transit authorities, brokers and Medicaid health plans. Providers running 80 to 170 vehicles have migrated here from legacy paratransit and NEMT platforms. No fleet minimum. 4.6/5 across 49 reviews. 13 consecutive SourceForge Top Performer awards.
