Rabot Energy: More customer satisfaction through automated dunning processes
On-time payments, full transparency, and more satisfied customers – for Rabot Energy, this is now a reality. Thanks to its collaboration with Billogram, the company has achieved these goals and significantly improved the customer experience. CEO Jan Rabe explains how the innovative German start-up, together with its partner, reimagined processes related to invoicing, receivables management, and customer service. And automated dunning is just the beginning.
Rapid growth requires scalable systems
Founded in 2021 as a greentech start-up, Rabot Energy offers dynamic electricity tariffs in Germany as an independent provider. Due to the energy transition, these tariffs quickly attracted great interest, and the company experienced rapid growth. “Our challenge was that our system couldn’t scale as quickly as we needed,” says Rabe. “Billing and customer service soon reached their capacity limits. We’re in constant dialogue with our customers and continuously develop our product accordingly. That’s why we were looking for a reliable partner to support our growth.”
Payment overview as the key to customer satisfaction
Another issue with the old solution was the lack of clarity about paid and unpaid invoices. “Our customers are tech-savvy and open to new solutions. What they primarily want is transparency – insight into their consumption and the ability to actively manage loads,” says Rabe. This requires smart meters and intelligent tools. But as the customer base grew, the system became increasingly confusing. The highly volatile electricity prices made tracking even more difficult. “We often had to send dunning and collection letters manually – not always at the right time, simply because we lacked the capacity.” An efficient system to ease the burden was urgently needed.
Positive changes within a year
The partnership with Billogram began last year. “After an initial exchange about our challenges, we were quickly on the same page,” says Sören Steckmest, VP Western and Central Europe at Billogram. Together, a solution was configured that is tailored to Rabot Energy’s requirements. “Our software now automates the entire invoicing process and makes it significantly more efficient,” adds Steckmest.
Four key improvements through the collaboration
1. Automated & flexible invoicing
Customers receive their invoices on time and with full transparency – whether they’re on dynamic or fixed tariffs. The entire process, including dispatch, is automated. Since partnering with Billogram, the number of on-time payments has increased by around 30%. The share of direct debit payments has also risen – a plus for payment security.
2. Clearer communication & less effort for customers
Thanks to an intuitive layout and real-time updates, customers understand their invoices and payments better. A self-service portal allows for direct communication through the invoice interface – including messages, inquiries, and clarifications – without detours through customer support. This reduces inquiries and lowers the chargeback rate by about 20%.
3. Intelligent dunning processes for quick resolutions
In the event of payment delays, automated dunning processes ensure fast resolution. Prior to due dates, soft reminders are sent via email or post. The processes are individually configurable – e.g., based on customer loyalty or previous payment behavior.
4. Scalability for the future
Thanks to modern, API-enabled ERP and output systems, Rabot Energy was able to integrate Billogram smoothly. The solution scales with growth – even as the number of customers and transactions increases, as Billogram’s SaaS platform is designed for large volumes.

Shared values: customer satisfaction and user-friendliness
From the start, it was clear: Rabot Energy and Billogram are committed to satisfied customers and a user-friendly solution. “What we appreciate about Billogram is the individual customization – no off-the-shelf solution,” emphasizes Jan Rabe. He was particularly impressed by customer-centric features like the self-service portal and the clear invoice layout. Especially in the German energy market, consumers increasingly desire digital access to their billing data – and that’s now possible.
The energy transition offers many opportunities for Rabot Energy – and the start-up wants to continue growing. To secure customer satisfaction as a competitive advantage, the partnership with Billogram will be further expanded. This way, the billing system can continuously adapt to new requirements.
