Build or buy? An honest look at running your own CSMS
Building a charging back-end looks cheap until you count roaming, payments and certification. Here is the full bill.
Every growing operator eventually asks whether to build its own charging management system.
The visible costs
OCPP handling, a driver app and a dashboard look like a few months of work.
The hidden costs
Roaming certification, payment compliance, firmware quirks across 40 charger models, 24/7 on-call, security audits.
Our take
Buy the foundation and build the edge. Use an API-first platform for the commodity layers and spend your engineers on what makes your network different.
