Expertise Across CSP Billing Operations

 

Calvi’s specialists have designed and operated billing environments where accuracy, continuity and traceability are critical. We understand how complex commercial events are reflected in the bill and where interpretation gaps create disputes, delayed payment, avoidable contact and revenue risk. We also know how to introduce Billing Intelligence without disrupting the systems that calculate and collect revenue.

Philipp’s Story

 “Over more than two decades at Deutsche Telekom, I worked across billing, order-to-cash transformation and revenue assurance, later leading the architecture of a next-generation billing system and helping shape billing strategy across 12 countries.

I joined Calvi to bring that operator experience to our customer engagements.”

Mischa’s Story

“I have worked in telecom since 2000 across interconnect billing, roaming, revenue assurance and fraud, later serving as Billing Director at Tele2. While mapping Tele2’s billing architecture, I saw the need to simplify fragmented systems and chose Calvi to support that transformation.

I now bring those operational lessons to CSPs managing similarly complex billing environments.”

Working With Calvi

 

What does a Calvi services engagement cover?
Engagements can cover discovery, Billing Intelligence strategy, scenario and journey design, technical architecture, integration, configuration, testing, deployment and adoption. The scope is aligned with the selected use cases and the CSP’s existing delivery model.
How does Calvi identify the right starting use cases?
Calvi assesses inquiry demand, customer friction, revenue exposure, data availability and delivery complexity. This helps prioritise scenarios that can demonstrate measurable value while establishing a reusable foundation for subsequent use cases.
How does Calvi work with CSP teams and delivery partners?
Calvi can lead product-specific delivery or work within a wider CSP programme alongside BSS and CRM teams, systems integrators, AI partners and channel owners. Responsibilities, interfaces and governance are agreed for each engagement.
Can Calvi support environments with multiple BSS platforms?
Yes. Calvi maps the relevant data, events and scenarios across existing billing and related BSS platforms while each system remains authoritative for its own records. This allows consistent Billing Intelligence to be established without replacing the underlying estate.
How are operational and commercial outcomes measured?
Relevant measures are agreed for each use case and may include inquiry volume, average handle time, first-contact resolution, payment performance, disputes, digital resolution and revenue at risk. Baselines allow realised value to be assessed after deployment.
How does Calvi protect billing continuity during delivery?
Calvi works alongside the existing BSS estate using controlled integration, validation, testing and phased deployment. Core platforms continue to calculate and manage the bill, reducing disruption to revenue-critical billing operations.
