How a major energy player accelerated and streamlined its customer relations?
Three divisions, a thousand advisors, tens of thousands of qualified appointments per year. A major French energy player has made Agendize the foundation of its Customer Relations Department, from amicable debt recovery to the subscription process. This study details the project's structural choices, the operational results achieved, and the lessons applicable to any multi-site Customer Relations Department.

An engagement and conversion platform deployed across three business divisions
A major player in the French energy sector manages several million customer interactions per year. Its customer relations centers handle a high volume across various channels and multiple sites. The group deployed Agendize across three distinct divisions in less than two months.
The first wave focused on mediation and amicable debt recovery. Deployment then extended to the Consumer Complaints department and subsequently to sales processes. Nearly a thousand advisors now use the platform daily. Tens of thousands of qualified appointments are processed through Agendize each year.
Advisors experience smoother customer connections and can more easily advise and process requests, while supervisors gain visibility into workflows. For the Sales department, nearly one in nine appointments results in a sale, from traffic fully qualified upstream by the platform.
The Customer Relations Department now manages its three activities on a single foundation with shared rules and comparable metrics.
A multi-site energy provider, millions of customer interactions every year
This energy player operates across the entire energy value chain in France. Its activities serve several million residential and business customers. The group manages a dense network of call centers spread across the country. Customers contact the company by phone and/or online. The volume of customer interactions amounts to millions each year.
Customer relations centers play a strategic role in the system. They handle routine requests, sensitive situations, and commercial opportunities. Their workload varies significantly depending on seasons and energy contexts. Business divisions must absorb volume peaks without compromising service quality. This requirement directly impacts advisor scheduling and the ability to offer available slots to customers. This large industrial group sought to make this scheduling more reliable across all its customer-facing divisions.
Three structural constraints for a large-scale Customer Relations Department
A multi-site Customer Relations Department of this size faces unavoidable constraints. Three key challenges capture the attention of Customer Relations Center Directors in groups dealing with millions of customer interactions annually.
Incoming volume and channel saturation
Usage varies across the group's business lines. For commercial activities, the platform fills schedules based on slots defined upstream by site managers. For residential customer service, the advisor themselves offers the customer an appointment to follow up on their request. For support mechanisms, the same process applies, supplemented by email campaigns inviting customers to book appointments.
No-shows and calendar productivity
Missed appointments impact advisor productivity. A schedule weakened by absences reduces sales capacity and degrades the quality of service delivered to customers who do show up. This issue translates into lost customer interaction hours each week.
Multi-site scheduling and unified management
The group's CRCs handle a considerable volume of customer inquiries daily, via web, phone, and email. Internal scheduling tools define available slots by reason and by advisor. The challenge then lies downstream: transforming these slots into qualified appointments through the right channel and with the right advisor. Without a consistent appointment booking process across all CRCs, conversion rates vary from one division to another, and performance measurement remains difficult to consolidate.
For this group, the challenge boiled down to three priorities. The first was to free up customer interaction time for advisors by simplifying the appointment booking process for both customers and the team. The second aimed to standardize this process across all CRCs with the same business rules and integrations. The third focused on precisely measuring appointment booking performance, by reason, by calendar, and by channel.
Conversion management is now exercised at various levels, from the CRC to regional groupings, up to a cross-functional marketing department.
Deploying the same tool across all CRCs paves the way for future integrations with the group's CRM, data lake, and cloud communication solutions.
Three waves, three business lines, a single enterprise technology foundation
Mediation and amicable debt recovery
The first wave covered mediation and amicable debt recovery. The department sends a personalized email link to each customer needing assistance with their supply continuity. The customer chooses their slot in a few clicks, typically within two days. The advisor receives the reason and context before the meeting. They then propose a payment schedule or an adjustment to their supply offer. This mechanism transforms debt recovery into a productive conversation for both parties.
In this scope, the customer chooses their own slot, on average within two days of receiving the personalized link. This short timeframe indicates a genuine need for quick reconnection at a time convenient for the individual. The customer in default of payment regains control over the pace of the interaction. The likelihood of reaching a quick amicable agreement is significantly enhanced.
Consumer Complaints
The second wave covered the Consumer department. The customer submits a request to this department. Upon reviewing the request, the advisor can send their customer a personalized, single-use appointment booking link via email. The customer chooses their slot (average observed appointment booking time: six to seven days). No more back-and-forth emails or unsuccessful call attempts that prolong complaint processing or create misunderstandings! Appointment booking creates satisfaction and will, in the future, fuel upsell opportunities.
In this scope, the customer books their appointment, on average, within six to seven days. This pace indicates a genuine need for quick request processing, at a time that fits the customer's daily schedule.
Sales Department and digital journeys
The third wave covered the Sales Department. The Agendize widget is integrated into the website for specific offers and products. Customers book appointments directly from the subscription process. Additionally, email campaigns direct qualified traffic to advisors' calendars. Appointments concern consumption reviews or subscription processes. Agendize transforms digital intent into qualified traffic for advisors.
In the Sales department, nearly one in nine appointments results in a sale, from traffic fully qualified upstream by the platform. The qualification mechanism generates prepared, ready-to-sign traffic. Advisors enter the sales conversation with a qualified file and a clear reason, which shortens the decision cycle.
A technical framework designed for a large enterprise
The technical scope was designed for a large enterprise. The login page relies on the internal authentication system for the thousand active licenses. The platform is connected to the group's email and SMS provider. Calendars synchronize with Outlook in the relevant departments. The internal scheduling tool opens or closes slots on schedules based on the current workload of the CRCs. Automatic email and SMS reminders ensure customer attendance at appointments. Supervisors have real-time dashboards on volumes, reasons, and calendars per division.
The group benefits from Agendize's security framework. The platform is ISO 27001 certified and GDPR compliant, with sovereign hosting. Agendize teams support each deployment wave with Level 2 support, expert training, and enhanced monitoring for sensitive topics. Adoption was rapid thanks to an interface designed for field use.
Tens of thousands of qualified appointments, a thousand equipped advisors, one in nine appointments resulting in a commercial conversion
The Agendize system processes tens of thousands of qualified appointments per year, across all divisions. This volume represents high-value interactions for the group.
Nearly a thousand active licenses are now deployed across the three divisions. This large-scale adoption occurred progressively, wave by wave. Advisors use the platform as a daily work tool and have integrated it into their routines.
Automatic email and SMS reminders ensure customer attendance at scheduled slots and reduce no-shows. This metric transforms a historical CRC pain point into a direct productivity gain for calendars.
Three actionable insights for a multi-site Customer Relations Director
Three key lessons emerge from this case for Customer Relations Directors of multi-site groups.
The first concerns customer interaction time. When appointment booking becomes smoother, advisors reclaim valuable minutes each day. These minutes enhance listening quality, case preparation, and first-contact resolution. Productivity increases without adding to the team's mental load. The advisor's role regains its primary value.
The second lesson relates to large-scale adoption. A progressive, division-by-division deployment secures the project and brings field teams on board. Early adopters become ambassadors for subsequent users. Best practices spread organically, based on concrete cases. Shared governance between business divisions becomes an asset when all use the same metrics.
The third lesson concerns measurement. A common platform produces comparable data from one division to another. No-show rates, conversion rates, self-service share, and average appointment booking time become shared indicators. The Customer Relations Department shifts from a reporting logic to daily operational management. Decisions are based on real-time consolidated figures, whereas quarterly reports dominated in the past.
