About
EV charging billing platform for a European energy provider: contract-based billing with loyalty programs, cardless charging via saved payment methods, and PAYONE-powered automated invoicing. Administrative reporting by station, provider, and period brought real-time visibility into transactions and billing errors for the whole charging network.
Challenge, approach, and impact
Challenge and Scope
Drivers couldn't set up long-term contracts or save payment info; every charge session was a separate manual payment relying on physical cards. Payment issues were hard to trace: reporting lacked detail, so billing errors and disputes took long to resolve for both sides. Scope: contract-based billing with loyalty perks, cardless digital charging via saved payment methods, and real-time transaction reporting for administrators.
How we built
Testimonials
Adam F.
NDA
“Billing was our blind spot: every payment complaint meant manual digging through exports, and drivers kept asking why they still carried plastic cards for a digital world. Innowise rebuilt the flow around contracts and saved payment methods, and the change was felt within weeks: drivers onboarded onto plans the way they subscribe to anything else, and PAYONE reporting showed us exactly where a failed transaction went wrong. The 50% processing speedup was measured, not marketing. Most telling: our partner network grew by a third, because new operators found integration painless. A team that understands real-world payment operations, not just code.“
