Case Study EV Charging

Driving the future of EV charging

As one of Europe’s leading High-Power Charging (HPC) networks, IONITY is on a mission to make long-distance electric vehicle travel seamless, sustainable, and scalable.

With over 5,000 HPC chargers across 757 sites in 24 countries, IONITY serves private drivers, fleet operators, and roaming MSPs across borders, languages, currencies, and tax systems.

Six electric vehicles from various manufacturers are parked side by side at IONITY charging stations in a scenic mountainous area surrounded by dense pine forest and steep cliffs under a partly cloudy sky

To scale at this pace in such a complex environment, IONITY needed more than a charging solution—they needed a financial engine built for cross-border growth. That’s where Riverty came in.

The challenge: Scaling with speed, complexity, and control

Operating across 24 countries, IONITY's rapid expansion placed growing demands on its financial infrastructure. As the company rolled out its HPC infrastructure across Europe, it faced increasing pressure to:

Support multiple VAT zones, nine currencies, and seven languages
Consolidate complex ad-hoc, roaming, bilateral, and subscription-based billing models
Secure cash flow reliability in a capital-intensive business
Automate financial processes to reduce operational overhead and ensure compliance

Each HPC site represents a significant capital investment—including infrastructure, installation, ground works, and O&M on top. Efficient revenue handling across all streams was non-negotiable.

The solution: A Finance Suite built for EV Charging

Riverty provided IONITY with a full-service EV Charging Finance Suite, enabling it to scale its revenue operations with confidence. The solution included:

Subscription management

Ad-hoc charging support via credit card and app

Charge Detail Record (CDR) consolidation and invoicing

Roaming and bilateral B2B invoicing

Failed payment handling and dunning

Certified invoice archiving and book quality

A black Hyundai Ioniq 6 electric vehicle is plugged into an Ionity fast-charging station at a modern EV charging facility, with several other chargers and a covered canopy visible in the background.

Whether for private drivers or B2B roaming partners, Riverty powered billing for:

Ad-hoc charges

Subscription models

Terminal payments (POS)

B2B invoices to MSPs (roaming)

B2B sub-MSP invoices

With experience from telecom and mobility sectors, Riverty helped IONITY shape charging behaviors through:

Multi-tier tariffs

Recurring billing

Loyalty and passport campaigns

The results: From 100% manual to 99% automated

16x growth in transaction volume

99% automation rate with just 1% manual oversight

15x growth — from 328 chargers in 4 countries to over 5,000 chargers (and growing) in Europe

Full VAT reconciliation and handling across 24 European countries

4x growth in tariffs

Riverty has been a strategic partner in simplifying complex financial processes—billing, reconciliation, and VAT compliance—at scale across 24 markets.

The power of subscription: loyalty, revenue, and retention

In a competitive EV market, subscriptions drive stickiness. Riverty enabled IONITY to build advanced subscription models that:

Increased revenue by up to 250% in key pilot markets

Boosted subscriptions by 2.4x in just one month

Encouraged charging habits and built long-term loyalty

When we introduced subscriptions to the EV charging market, it was a novel feature. Today, it’s everywhere, shaping charging habits and driving brand loyalty. We’re proud to support this trend with an expanding range of sophisticated tariffs that are delivering strong results.
