Field Service Modernization
Field Services
Creative MultiCare operated and dispatched 300+ field technicians, in two states and 4 submarkets, on paper invoices and a decade-old desktop app. We built the API and all the integration to modernize it — and designed and built a mobile app that took their entire field operation paperless.
The Challenge
Creative MultiCare runs a large field-service operation — more than 300 field technicians throughout Georgia and Florida every day. When they came to us in 2024, the whole operation was dependent on paper invoices: every technician filled out paper invoices by hand, and those invoices were physically delivered to a Creative MultiCare location once a week, then hand-keyed into the back-office system.
That back office was a single desktop application that hadn't been meaningfully updated in nearly a decade, backed by an on-premise SQL Server managed by an outside IT vendor. This system while reliant on paper invoices and a manual process, it still did its job, but it was a closed, aging system — no path to mobile, no real-time data, and a week-long lag between work done and work billed.
Our Approach
We didn't rip out the system they depended on — we modernized around it. We stood up a new ASP,Net Core API over their data, then built all of the integration that connects the legacy desktop application to that API, so the decade-old VB.Net desktop app keeps working while now reading and writing through a modern, secure cloud service.
Then we designed and built — end to end — a mobile app for their technicians: a .NET MAUI app where field staff capture jobs, photos, and customer signatures and submit invoices from their assigned mobile device, with no paper involved. Shared .NET contracts let the legacy desktop, the new mobile app, and a new web app all work against the same data and business rules, and the platform runs on Azure with Microsoft Entra ID security.
Outcomes
Creative MultiCare's field operation no longer runs on paper:
300+ technicians now capture work, photos, signatures, and invoices in a mobile app instead of on paper forms.
The weekly ritual of delivering paper invoices to an office and re-keying them by hand is gone — data flows straight from the field into the back office.
The decade-old desktop application is now fully integrated with a modern cloud API instead of being a closed, standalone system.
A new web application gives them a path to migrate off the legacy desktop over time, on their own schedule.
