We provide expert advice, systems integration, and custom software development to enhance charging operations.
Who We Are
Metergram is a 50-person software development consultancy specializing exclusively in EV charging infrastructure. For over eight years, we have worked with Charge Point Operators, CSMS platforms, OEMs, utilities, and fuel retailers across the world.
Our team consists of engineers who deeply understand the EV charging domain – OCPP, OCPI, OpenADR, and the unique operational challenges CPOs face as they scale their networks.
Founded in 2018, Metergram has built deep expertise in EV charging infrastructure software. We are active members of the Open Charge Alliance, EV Roaming Foundation, E-Mobility Europe, and OpenADR Alliance.
Our Partnership with LMS
We partner with LMS to extend what their platform can do for you. While LMS provides the core charging management system, we build the custom integrations, tools, and applications that solve your specific business challenges.
Think of us as your technical partner for everything beyond standard CSMS functionality.
How We Work – Discovery First
We do not typically start with large development projects. Instead, we offer fixed-price discovery engagements that give you complete clarity before committing to implementation:
- Know exactly what a solution will cost
- See designs and specifications before any code is written
- Get documentation you own and can use with any developer
- Make informed decisions about timing and investment
No obligation to proceed with implementation. The discovery work is valuable on its own.
Four Common Challenges We Solve
Many LMS clients face similar challenges as they grow. We have created fixed-scope discovery packages for the most common ones:
1. ERP Integration
Challenge: Automating invoicing and financial reporting between your charging platform and ERP system.
Discovery Package: Complete integration scoping with architecture options, requirements, and budget estimates.
Timeline: 2-3 weeks

2. Custom Data & Analytics
Challenge: Building reports and analysis that your CSMS vendor dashboards cannot support.
Discovery Package: Data architecture design for owning your charging data and connecting to BI tools.
Timeline: 2-3 weeks

3. Commissioning Tools
Challenge: Speeding up charger installations and reducing field technician errors.
Discovery Package: Commissioning process audit and mobile app specification.
Timeline: 2-4 weeks

4. Custom Driver App
Challenge: Building a branded charging app instead of using white-label solutions.
Discovery Package: Complete app design with UX mockups, features, and development roadmap.
Timeline: 2-3 weeks
