OTB Cockpit – Medical supply field app

Medical supply under real network and time pressure

In medical supply, appointments, consultations, and documented orders determine whether processes run smoothly. Field teams often work on site at customers’ premises, in facilities, or on the road—stable mobile coverage or Wi‑Fi is not guaranteed everywhere. If order capture and master data are online-only, wait times, duplicate notes, and media breaks emerge that hurt quality and traceability.

At the same time, large volumes of customer and product information must be at hand: item variants, prescription context, and customer-specific data must not degrade into improvised searches across disconnected systems. The challenge was a mobile solution that bundles this complexity without overwhelming users—and that still works when connectivity drops or is intermittent.

Data volume, consistency, and day-to-day operations

Several hundred thousand customer and product records must be available in the app so field staff and specialist advisors on site can use the same depth as back-office processes. That requires local storage, search and filter logic, and conflict avoidance on later sync: what changed offline, what must reach the server first, which fields are authoritative?

Without a deliberate offline strategy, the risk grows of inconsistent states, duplicate capture, or lost entries—in an environment where traceability and clean order data are central. The app therefore had to be designed for offline operation from the start, not as an afterthought.

Cockpit app with full offline capability

For our healthcare client we implemented the OTB Cockpit app: a mobile cockpit application for order capture in medical supply that presents all relevant information in one place and guides structured input. The app keeps customer and product data locally so field staff can work without connectivity—with clear workflows instead of a server round trip for every tap.

Synchronization with the backend is on demand: when the network is available, data can be reconciled; the user decides when sync makes sense. Technically this relies on an offline-first architecture, robust local storage, and defined REST interfaces to the server—so recurring field processes stay predictable and repeatable.

Made in Germany delivery

Groenewold IT Solutions in Leer, East Frisia, designed and built the solution—with short communication paths, direct alignment with the client, and maintainable architecture. We support such projects from domain clarification through mobile UX for field work to integration and evolution; rooted regionally, deployable nationwide.

Scale in daily field operations

The app is used every day by several hundred field staff—a scale that demands stability, performance with large datasets, and a resilient UI. Offline use removes much of the friction from analog or half-digital capture; teams can consult and document on site without connectivity issues dominating the conversation.

Reference for healthcare and field-service apps

OTB Cockpit shows how we deliver industry-specific mobile apps with heavy data requirements and a field focus—from offline-first and synchronization to productive use in large teams. If you are planning a comparable solution for supply chains, field service, or complex master data, this project is a concrete example from our practice.
