You pay once. That is it. Five Hundred is a CAPEX investment, not a subscription. You pay an implementation fee to build and deploy the platform inside your Microsoft 365 tenant. After that, the software is yours — no monthly fees, no per-user seat costs, no renewal negotiations. As you add plants, technicians, or sites, your software cost does not change. Most clients reach TCO breakeven inside 18 months compared to the SaaS alternative they were considering.
