For charge point operators, roaming networks and fleets
Custom CSMS development for your EV charging business
A CSMS is the software that runs your EV chargers. Tell us how you want yours to work, and we build it: your brand, your payment provider, your driver app and the tools your team already uses.
You don't start from zero. Every project is built on Savekar, a platform already running live chargers.
- Your chargers
- Any brand that supports OCPP, AC or DC
- Roaming
- Listed in partner charging apps (OCPI 2.2.1)
- Your systems
- Connected through our API and webhooks
- Built for you
- Driver app, web portal, payment provider
Requirements
Define your scope: available today and built for you
Select the capabilities you need. Your selection is attached to your demo request, and the summary shows what is available today and what we build for your project.
Delivery models
Build in-house, buy off the shelf, or build on Savekar
Three ways to own a charging platform. They differ in starting point, control, and who carries the ongoing engineering.
Build in-house
- Starting point
- A greenfield codebase
- Brand and workflows
- Fully custom
- Protocol and roaming upkeep
- Your engineering team
- Time to first live charger
- Longest: every component is built first
Off-the-shelf SaaS
- Starting point
- A packaged product
- Brand and workflows
- Limited to the product's model
- Protocol and roaming upkeep
- The vendor
- Time to first live charger
- Short, if the product fits as-is
Custom CSMS on Savekar
- Starting point
- A production platform, extended for you
- Brand and workflows
- Configured and extended to your model
- Protocol and roaming upkeep
- Savekar
- Time to first live charger
- Short for existing capabilities; scoped timeline for new work

FAQ
Frequently asked questions
Scope, delivery, compatibility and commercials.
What is a CSMS?
A charging station management system: the software that connects to your EV chargers and runs monitoring, pricing, driver payments and reporting. Savekar is a CSMS; a custom CSMS is Savekar extended around your business.
Is a CSMS the same as a CPMS?
Yes. CPMS (charge point management system) is the term used with OCPP 1.6; CSMS is the term OCPP 2.0.1 uses. Both describe the same software.
Do I need to understand APIs, OCPP or OCPI?
No. Describe the outcome you need; our team handles the technical design and explains any trade-offs in plain language.
Do you already have a driver mobile app?
Not as a ready-made product. A branded iOS or Android app is built and scoped per project. Today, drivers start sessions from WhatsApp, with RFID cards or through partner charging apps.
Can you connect our payment provider?
Tell us your provider, such as Stripe, Adyen, PayPal or a local gateway, and the payment methods you need. We confirm availability in your country and the integration effort, and include it in the scope before work begins.
Can you build it for my country?
Yes. The platform is not tied to one market. During scoping we confirm your payment provider, currency and local requirements, and state clearly what is available and what will be built.
What does custom CSMS development cost?
Each project is quoted after discovery, because cost depends on how much runs on the platform today and how much is new. Starting from a production platform puts the budget into what differentiates you.
How long does a custom CSMS take?
It depends on scope. Existing capabilities are configured first; new components get their own timeline in the proposal, agreed before you commit.
Will it work with the chargers I have?
Yes, if they support OCPP 1.6J, regardless of brand. We confirm your exact models during scoping.
