Contract management at stadtwerke Clausthal-Zellerfeld

Anyone working in the energy sector knows that the mountain of contracts, compliance rules, and deadlines can be overwhelming. Whether it is power supply, grid utilization, or water infrastructure—missing a critical date can quickly scale into a major headache. At Stadtwerke Clausthal-Zellerfeld GmbH, the daily reality looked familiar to many: contracts were either printed out in heavy binders or scattered across various department drives. A true overview? Nowhere to be found. This led to missed cancellation deadlines, accidental duplicate contracts, and unnecessary costs.

Franziska Riefling, who runs contract management at the utility company, decided it was time for a change. She wanted to eliminate the chaos and find a system that actually works for the team. They chose Inhubber. In this case study, you will see how transitioning to modern contract management for energy companies brought structure back to their operations and how the automated platform helped them put missed deadlines and double-billing behind them for good.

Before using Inhubber, contract management at Stadtwerke was highly decentralized. Contracts were stored either as paper files in binders or as digital files spread across various departments. Managing these documents was a manual process, and there was often no central overview of active contracts. This led to the following problems:

1. Missed deadlines
   Manual deadline tracking was unreliable. Termination and payment deadlines were often overlooked, resulting in unnecessary costs due to automatic renewals or late payments. The company missed important deadlines and had no structured system in place to monitor them automatically.
2. Lack of transparency
   Since each department had its own system for storing documents, neither the legal team nor upper management had a centralized overview of all contracts. Contracts were saved in various folders and formats, making the overall structure difficult to navigate. Searching for specific agreements was time-consuming and frustrating.
3. Duplicate contracts
   Without a centralized overview, errors occurred more frequently—such as the accidental signing of duplicate contracts—resulting in unnecessary costs and extra administrative work.
4. High time expenditure
   Managing contracts manually in paper format and basic Word lists was not only error-prone but also extremely time-consuming. Searching through binders and monitoring deadlines cost employees valuable time that could have been used more productively.

Franziska Riefling summarizes the situation: “We constantly had issues with missed deadlines, duplicate contracts, and unnecessary costs because we lost track of our agreements. It became clear that we needed a digital solution to eliminate these inefficiencies.”

After a thorough evaluation of several providers, Stadtwerke Clausthal-Zellerfeld GmbH chose Inhubber as its central solution for contract management.

The decision was based on several factors, with user-friendliness, centralized document storage, and automated dealine monitoring being the most convincing.

1. Centralized and Transparent Storage
   One of Inhubber’s key advantages was the ability to store all contracts in one central location. Instead of being distributed across departments, all contract documents are now stored in a structured, digital environment. With clearly organized workspaces, folders, and subfolders, contracts can be sorted by department, type, or project.
   This central storage simplifies access to all documents. Franziska Riefling notes:
   “With Inhubber, we finally have a complete overview of our contracts. It’s easy to use and saves us a huge amount of time since we no longer have to dig through multiple folders.”
2. Automated Deadline Monitoring
   Automated deadline tracking is one of Inhubber’s most powerful features and solves one of the biggest challenges the company faced before implementation.
   Inhubber automatically tracks contract terms, termination deadlines, and payment due dates. When a deadline is approaching, responsible employees receive timely notifications so they can act accordingly.
   This feature has already helped Stadtwerke avoid unnecessary contract extensions and reduce costs.
   “Automated deadline monitoring is especially important for us. We used to rely on manual lists, which were often inaccurate. Now we can be confident that no deadline goes unnoticed,” says Riefling.
3. Faster Access and Efficiency Gains
   Thanks to Inhubber’s powerful search and filter functions, Stadtwerke Clausthal-Zellerfeld can now find contracts in seconds—something that used to take much longer. The platform features an intuitive user interface that allows employees to search for documents by various criteria, speeding up the entire process.
   The technical department, accounting, and executive management in particular benefit from this new level of efficiency.
   “The efficiency gains are enormous. We used to spend hours searching for contracts. Today it takes just a few seconds to locate the right document and extract the necessary information,” explains Franziska Riefling.
4. Security and Access Control
   Another key benefit of Inhubber is security. Since all contracts are stored in the cloud, the company can ensure that contract documents remain secure—even in the event of a server failure or local data loss.
   The centralized and digital environment guarantees data integrity, while access rights can be clearly defined. Inhubber offers flexible permission levels, so only authorized staff can view or edit certain contracts.
5. Cost Savings Through Error Prevention
   By implementing Inhubber, the company not only improved efficiency but also achieved direct cost savings.
   Mistakes like the signing of duplicate contracts are now a thing of the past. Additionally, automated deadline tracking helps prevent costly automatic renewals.
6. User-Friendliness and Quick Implementation
   Another major advantage of Inhubber was how easy it was to implement and use.
   The city utility company did not require extensive IT integration, and after a short training session, employees were able to work with the system immediately.
   “The implementation was fast and straightforward. Our team adapted quickly and could start using the platform in no time,” says Riefling.

Although Stadtwerke Clausthal-Zellerfeld already uses Inhubber extensively, Franziska Riefling sees additional potential for the platform in the future.

The next steps include integrating additional departments and systematically digitizing older contracts.

“We’re not yet using Inhubber to its full capacity. But we plan to expand its use even further and also digitize legacy contracts,” Riefling adds.

The story of Stadtwerke Clausthal-Zellerfeld clearly proves that smart digitalization simply makes daily work life better. For modern utilities and public services, organizing documents is no longer a boring administrative chore—it is a core foundation for preventing costly financial mistakes.

With Inhubber, the team finally has complete clarity. Binders and messy folder structures have been replaced by a central, secure workspace. Thanks to proactive notifications, no one has to stress about fine print or surprise auto-renewals anymore. What really stands out about Inhubber is how intuitive and scalable it is—requiring no heavy IT integration. It serves as an ideal solution for contract management for public administration and effortlessly adapts to the highly complex needs of municipal infrastructure. Ultimately, Clausthal-Zellerfeld demonstrates that when software is user-friendly, teams embrace it instantly—making administrative workflows smooth, secure, and future-ready.
