Frankfurt-based Commerzbank, one of Germany’s most venerable financial institutions and its second-largest retail lender, has successfully completed a significant overhaul of its internal digital infrastructure, transitioning from fragmented manual operations to a streamlined, automated onboarding system. By leveraging the Camunda 8 process orchestration platform, the bank has effectively modernized its approach to customer acquisition, particularly within the small business and private banking sectors. This strategic shift addresses long-standing inefficiencies that previously saw onboarding timelines stretch into weeks, marking a pivotal moment in the bank’s broader digital transformation journey.
The move comes at a critical juncture for the European banking sector, where traditional "incumbent" banks face increasing pressure from agile neobanks and fintech startups that offer near-instantaneous account opening. For Commerzbank, a bank with a history dating back to 1870 and a massive footprint in the German "Mittelstand" (small to medium-sized enterprise) sector, the necessity of modernization was underscored by the complexity of its legacy systems. Before this implementation, the bank lacked a centralized, automated procedure for smaller business customers, relying instead on a disjointed series of manual interventions spread across multiple departments.
The Challenge of Legacy Fragmentation
For decades, the process of bringing a new business client into the Commerzbank ecosystem was characterized by administrative silos. Essential functions—ranging from the initial creation of customer profiles and contract documentation to the rigorous requirements of identity validation and Know Your Customer (KYC) compliance—were handled manually. These operations were distributed across various back-office teams and advisory clusters, leading to a lack of transparency and significant delays.
Sebastian Kreuzer, Product Owner of Digital Onboarding within Commerzbank’s Accounts and Deposits Cluster, noted that prior to three years ago, a dedicated digital onboarding process for small business customers simply did not exist. Instead, the bank relied on a traditional model where advisors and back-office staff manually input data, verified physical documents, and navigated internal bureaucracies to activate products like digital banking and corporate credit cards. In a competitive financial landscape where speed is a primary differentiator, a process that took weeks was no longer viable.
The complexity was not merely administrative but also regulatory. German financial institutions operate under some of the world’s strictest anti-money laundering (AML) and KYC regulations, overseen by the Federal Financial Supervisory Authority (BaFin). Any automated solution had to not only be fast but also provide ironclad audit trails and ensure that every regulatory "building block"—from ID verification to risk assessment—was executed without error.
Orchestration as a Strategic Blueprint
The solution identified by Commerzbank was not to build a single, monolithic onboarding application, but rather to adopt a modular orchestration strategy. By utilizing Camunda 8, a cloud-native process orchestration platform, the bank was able to decouple individual tasks into reusable components. This "building block" approach allowed the bank to rethink the onboarding journey from the ground up.
Under this new architecture, the onboarding flow is treated as an end-to-end orchestrated process. When a new customer applies, the platform triggers a series of sub-processes. For instance, one component handles the generation of contract documents, another manages the "legitimation" or ID verification process, and a third handles the technical activation of the account and associated digital services.
This modularity proved to be a breakthrough for the bank’s internal efficiency. Because these components—such as KYC validation and customer number generation—were built as independent sub-processes, they could be reused across different business lines. After successfully implementing the system for small business customers, Commerzbank was able to replicate the model for private retail customers with minimal modifications. While private customers require different contract types and specific validations, the underlying "engine" for identity verification and product activation remained the same.
Chronology of the Transformation
The transition to an automated orchestration model followed a structured three-year timeline, beginning with the identification of the small business segment as the primary area of need.
- Phase I: Discovery and Design (Year 1): The bank engaged in extensive workshops involving cross-departmental stakeholders. The goal was to map out every manual step in the legacy onboarding process and identify how these could be translated into BPMN (Business Process Model and Notation) workflows. This phase was described by Kreuzer as labor-intensive but foundational, as it required defining clear responsibilities for every process step.
- Phase II: Small Business Implementation (Year 2): The bank deployed the first iteration of the orchestrated process on Camunda 8. This phase focused on integrating various internal APIs and third-party services for ID verification and credit checks. The result was a dramatic reduction in onboarding time, moving from weeks to, in many cases, a single digital session.
- Phase III: Scaling and Replication (Year 3): Following the success in the business sector, the "blueprint" was applied to the private customer segment. This phase demonstrated the "time-to-market" advantage of orchestration, as the bank did not have to start from scratch. Instead, it reused the majority of the existing process components, significantly reducing development costs and deployment time.
Data and Operational Impact
The shift to automated orchestration has yielded quantifiable benefits for Commerzbank, particularly regarding operational agility and resource allocation. While the bank has not released specific internal cost-saving figures, industry benchmarks for such digital transformations suggest that automating KYC and onboarding can reduce operational costs by 30% to 50% while improving conversion rates for new applicants.
One of the most significant impacts has been on "Time to Market." In the traditional banking model, launching a new product feature or updating a compliance check could take months of coding and testing across various siloed systems. With a modular orchestration platform, Commerzbank can now update a single "component"—such as a new ID verification vendor—and have that change reflect across all onboarding processes (both business and private) simultaneously.
Furthermore, the bank has established a model of "clearer responsibilities." In the old manual system, errors often fell into "no man’s land" between departments. Under the new system, every process component has a designated owner responsible for its performance and maintenance. This ownership model ensures that the digital infrastructure is constantly optimized rather than left to degrade.
Addressing the Complexity of Distributed Systems
Despite the successes, the transition has not been without challenges. Kreuzer admitted that one unforeseen drawback of a highly orchestrated, modular system is the increased complexity of incident monitoring. In a manual, monolithic process, an error is usually easy to locate because the entire file is in one place. In a distributed, orchestrated environment, a customer may experience a failure at the end of the chain, but the root cause could be buried deep within a sub-process like "KYC Validation" or "Document Generation."
"If a customer faces a problem in the onboarding process and complains, then that complaint will always come at the end of the orchestration process," Kreuzer explained. Because the end-to-end process is composed of multiple independent sub-processes, tracing an error requires sophisticated monitoring tools and high levels of coordination between the teams responsible for different components. To mitigate this, Commerzbank has had to invest in better communication protocols and enhanced observability tools to ensure that when a "legitimation" error occurs, it can be identified and resolved without derailing the entire customer journey.
Broader Industry Implications and Future Outlook
Commerzbank’s journey serves as a case study for the "Composable Banking" movement, where financial institutions move away from rigid legacy cores toward a flexible ecosystem of specialized services. By treating onboarding as a series of orchestrated services rather than a single fixed path, Commerzbank has positioned itself to be more resilient to future regulatory changes or shifts in market demand.
The implications for the German banking market are significant. As the "bank for the Mittelstand," Commerzbank’s ability to provide a frictionless digital experience is essential for retaining its dominant position among entrepreneurs who increasingly expect consumer-grade digital experiences in their professional banking.
Looking forward, the bank is expected to continue expanding this orchestration model into other areas of its operations, such as loan processing and mortgage applications. The success of the onboarding project has proven that even a 150-year-old institution can achieve the agility of a fintech if it adopts the right architectural philosophy. The "blueprint" established by the Accounts and Deposits Cluster is now a candidate for wider adoption across the bank’s international branches, potentially standardizing the Commerzbank experience globally.
In conclusion, Commerzbank’s implementation of Camunda 8 represents more than just a technical upgrade; it is a fundamental shift in how the bank perceives its operational workflows. By breaking down the complex, manual "monolith" of onboarding into manageable, reusable components, the bank has not only solved a pressing efficiency problem but has also built a scalable engine for future innovation. While the challenges of monitoring a distributed system remain, the gains in speed, clarity, and customer satisfaction suggest that process orchestration will remain at the heart of Commerzbank’s digital strategy for the foreseeable future.
