How ChargeOnSite built a charger-agnostic platform and moved beyond white-label software.
ChargeOnSite delivers EV charging across commercial and multifamily properties managed by major real estate operators.
As an EV charging infrastructure provider, ChargeOnSite needed a partner to build and evolve its software.

ChargeOnSite started with a familiar EV charging problem, rented software worked at a small scale, but limited control as the network grew.
A single hardware vendor limited charger choice and white-label software removed that limit, but introduced new costs and lock-in at larger scale.
Per-charger costs grow fast
Per-charger licensing that's cheap at 20 units is punishing at 2,000.
Long locked in contracts
Once signed for 2–3 years, every new feature depends on the white-label provider.
Expensive Migration
Price increases leave you choosing between higher fees and a costly migration.

We engineered ChargeOnSite's platform end to end — charging, energy, billing, apps and operations in one system.
Charger-agnostic core
Support multiple brands and migrate OCPP 1.6 to 2.0.1 live.
Grid & energy management
Balance and control charging load across multiple sites.
Session management
Manage charging from plug-in through payment and monitoring.
Billing & accounting
Connect Stripe payments to Zoho through automated API flows.
Driver & property apps
Give drivers and property teams one branded experience.
The work began in 2022, when public guidance on OCPP, charger communication and real-world hardware behavior was limited.
Built integrations from scratch. There was no mature implementation playbook to copy from.
Handled compliant and non-compliant chargers, different hardware behavior and one consistent driver experience.
We evolved without rebuilding, kept the live platform current as protocols and requirements changed.

ChargeOnSite now runs charging, energy, billing and support on software it owns.
Charger-agnostic for good
ChargeOnSite can onboard any hardware brand, never blocked by a vendor relationship.
Built to scale

Full ownership
ChargeOnSite owns the platform and its data.
One branded network
15,000+ charging sessions across different locations.
