The problem

No single place to see and run everything

Checking chargers meant manual checks on site, billing meant manual invoicing, and information was scattered across different places. That doesn’t work once you have more chargers and more customers.

What they needed

  • See every charger’s status live, without visiting the site
  • Charge customers automatically for each session
  • Give customers a simple way to see their charging
  • Give the team one dashboard to run it all

What we built

One platform for chargers, customers and payments

  • Live charger status

    Every charger reports its status in real time, so the team knows what’s happening without going on site.

  • A customer dashboard

    Customers see their live charging session and their history in one simple place, on any phone.

  • Admin controls

    The team can monitor chargers, review sessions and act quickly, without digging through logs.

  • Billing that runs itself

    Each charging session is billed and paid automatically, with a clean record of every payment.

  • Early warnings

    Problems with a charger are flagged to the team, so small issues are fixed before they grow.

  • Secure sign-in

    Customers and staff each see only what they should, keeping personal data safe.

How we did it

Five phases in nine weeks

  1. 1

    2 weeks

    Chargers talking to the platform

    Connected the chargers so they report their status reliably, and set up session tracking.

  2. 2

    3 weeks

    The system behind it

    Built the part that manages customers, sessions and records securely.

  3. 3

    2 weeks

    Customer and admin dashboards

    Built both dashboards, with live session views and controls for the team.

  4. 4

    1 week

    Billing and payments

    Added automatic billing and payment capture, with a full payment history.

  5. 5

    1 week

    Testing and launch

    Tested everything end to end and made sure it was stable for real use.

Challenges

What was hard, and how we solved it

  • Keeping live updates reliable, even on patchy networks

    How we solved it: We built the connection between chargers and platform so updates stay consistent when the signal drops.

  • Turning charging sessions into accurate bills

    How we solved it: We designed session tracking and billing together, so every payment matches a real session.

  • Giving the team a clear view

    How we solved it: We built an admin dashboard focused on what operators actually need to see and do.

  • Keeping customer data safe

    How we solved it: We added secure sign-in and different access levels for customers and staff.

The result

A platform the business can grow on

  • Live view of every charger and session
  • Billing and payments that run themselves
  • One dashboard for the whole team
  • A clear, simple experience for customers
