ERE
Earn money by charging your electric car or truck.
The problem
Charging your EV with green power saves CO₂, but almost no one could cash in on it. From 1 January 2026, ERE also replaces the old HBE system: fuel suppliers must green their sales and buy ERE certificates from charge-point owners via booking providers like Den Hartog.
The solution
A complete administration portal that handles the whole chain: from yield calculation and charge-point registration to digital authorisation, document verification and payout: on web, iOS and Android.
What it does
- Automatic ERE yield calculation
- Charge-point & MID-certification management
- Digital authorisation via iDEAL (Mollie)
- Document verification & kWh logging (bulk import)
- Holding/subsidiary structures with role-based access
- Admin verification workflows, analytics & real-time messaging
- Web + iOS + Android
- One codebase, three platforms
- 2026

From website to platform.
In 2025 we built Den Hartog's website. In 2026 the ERE platform was added. It all runs on our own hosting and is managed by us.
