When Inquiries Turn into Clear Digital Workflows
Portal projects create value especially when customers, citizens, or business partners can complete recurring tasks independently and in a transparent manner.
A good portal guides them step by step through the process: checking order status, uploading documents, updating master data, initiating approvals, or tracking service cases.
Portal development becomes particularly valuable when it provides tangible relief:
Fewer follow-up inquiries: Users can see for themselves where a process stands and what needs to be done next—Support workload is significantly reduced.
Less rework: Documents, supporting evidence, and master data are fed into the process in a more structured manner.
Improved data foundation: Information is not entered multiple times but is drawn from the appropriate systems.
A shared status update: Everyone involved sees the same information and knows what the next step is.
For Which Portal Projects We Are the Right Partner
We excel particularly in portals where users need to be guided securely through applications, documentation, status updates, and approvals—with a clear user interface, integrated legacy systems, and reliable operation.
These areas of focus align particularly well with our experience:
Application and Case Management Portals
Self-Service Portals for Banks, Insurance Companies, and Government Agencies
Customer and Insured Person Portals
Specialized Portals for Complex Processes
Partner, Broker, and Agent Portals
What Sets Us Apart: Portals That Connect Processes and Systems
A portal is ineffective if it stops at a visually appealing interface, an isolated backend, or digitized forms. We handle the entire digital process—clear user guidance, system integration, and operations—all under one roof—so that users can act more quickly and systems work together reliably.
UX and engineering under one roof: At doubleSlash, user-centered design, front-end development, back-end integration, security, accessibility, and operations come together, rather than being split between concept and implementation.
Making critical workflows resilient early on: We test prototypes and portal workflows at the points where users would likely abandon the process. The insights gained are directly incorporated into the user interface, process logic, and requirements.
Safely guiding complex processes: We build application forms, authentication/SSO, identity verification, and approvals so that users follow clear steps and back-end systems work together seamlessly.
Eliminating silos: We integrate CRM, ERP, authentication, and legacy systems so that up-to-date data can be used in a controlled manner within the portal.
Building for Automation: We design status queries, uploads, and approvals with an “API-first” approach so they can later be securely automated or utilized by wizards.
Staying effective after go-live: We ensure operations, monitoring, feedback, and a roadmap so that maintainability and further development don’t end after launch.

Guide users quickly to their destination
The ZF Mobility Assist app showcases key capabilities that are also crucial for portal development: guiding users quickly to their destination, presenting real-time data in an understandable way, and delivering a stable application across various devices. Relevant trip data and features are consolidated into a clear digital interface.
Clear user guidance: Find a ride, understand the status, and take the next step.
Making system data usable: Consolidating real-time, map, and availability information in an easy-to-understand way.
Stable digital application: Scalable architecture, cross-platform implementation, and comprehensive testing.
Start with a portal assessment
If your portal is outdated, users are abandoning processes, or multiple systems need to be consolidated, a portal assessment is the right place to start.
You don’t need to have a finalized requirements specification yet. It’s helpful to provide:
A description of the existing portal or the portal concept
Key user groups
Key processes or application workflows
Known backend systems
Open questions regarding the Accessibility Enhancement Act (BFSG), security, or operations
