From Paper to Total Control
Deuma’s Transformation with Protecnus
SUCCESS STORY
In an industry where operational efficiency and data traceability are critical, Deuma SRL, an Argentinian company specialising in air conditioning maintenance, achieved a significant step forward in its operations thanks to the implementation of Protecnus, the leading management software for businesses delivering preventive and corrective maintenance services.
The Challenge: Scaling Without Losing Control
Approximately seven years ago, Deuma reached a turning point. The sustained growth of its operations was beginning to strain traditional processes: paper work orders, Excel spreadsheets, equipment histories scattered across the office, filing cabinets full of folders, repetitive tasks, and wasted administrative time. The lack of traceability complicated both internal management and customer relationships.
That was when they decided to implement specialist management software. “We needed a robust solution that would not only organise our services, but integrate all areas of the business into one single system,” says Guillermo Massucco, General Manager of Deuma.
The First Changes
Implementing Protecnus marked a clear before-and-after moment. In just three months, Deuma was able to digitally schedule and manage 100% of its technical services. This resulted in a 60% reduction in administrative tasks and improved efficiency in time and resource management. Notably, part of Deuma’s administrative team—previously 100% dedicated to service management—can now support other areas of the business, as planning, tracking, and service management are now handled by one person instead of three full-time employees.
The digitalisation of technical processes was key: technicians now complete reports directly through the mobile app, sign digitally, and attach photos, dramatically streamlining document management.
Total Control with Real-Time KPIs
One of the features Deuma values most day to day is KPI monitoring within the Protecnus platform. This enables the business to view real-time operational performance across technical service teams and the wider business.
“Previously, we managed this type of tracking in separate spreadsheets, with data that was always late or incomplete. Today, with Protecnus graphical dashboards, we make decisions based on instantly updated information in a format that is very easy to read.”
This detailed KPI visibility has enabled them to:
- Identify opportunities to improve resource allocation
- Measure individual and team productivity
- Optimise service routes, among other improvements
In the words of Alberto Vega, Operations Manager:
“The KPIs have become our daily compass. Today we know exactly how we are performing and where we can improve, without waiting until month-end to realise it.”
Itestor: The Ideal Administrative Complement
With the addition of Itestor, the native ERP integrated with Protecnus, the business also automated its commercial management and stock control. From the same platform they can now:
- Manage spare parts and material stock in real time
- Send quotations directly from the platform
- Link work orders to stock and purchasing movements, among other functions
Improved Customer Relationships
One of the greatest impacts has been seen on the customer side. Through the Protecnus Customer Platform, end users can now access service history, download certificates, request visits, and check equipment status.
More than 80% of active customers already use the platform, increasing perceived customer satisfaction. This translated into 35% more contract renewals in the last year. Guillermo describes Protecnus as “a tool that pays for itself within a few months of use.”
The Biggest Benefit: Total Centralisation
Alberto Vega, Operations Manager at Deuma, explains: “The greatest benefit Protecnus gave us was the ability to centralise our entire operation in one system. From technician work orders to stock movements and final reports: everything is digitalised, unified, organised, and updated in real time.”
Thanks to this integration, Deuma improved efficiency, reduced errors, and gained greater operational visibility—allowing them to grow without sacrificing service quality.
An Example in Action
During the last peak season, a well-known Argentinian company experienced a critical failure in its office climate control system. Thanks to the planning and agility provided by Protecnus, in less than 15 minutes Deuma had assigned a technician, reserved the required part, and notified the customer. In under three hours, the system was fully operational again.
Importantly, throughout the process, the customer could view the live status of their service request in real time—providing reassurance and trust, a major value-add for any maintenance service provider.
Technical Team Adoption
Technicians were central to the transformation. Although there was some natural resistance at first, they quickly adopted the tool as part of their daily routine. Today, all technicians use the Protecnus mobile app to record tasks, access equipment history, and sign digitally. This reduced data-entry errors by 90% and completely eliminated paper usage in the field.
Go Back? Impossible.
When asked whether they could return to working without Protecnus, Deuma’s answer is clear:
“Going back to paper, Excel, folders… would be going backwards years. Today it would be unthinkable to run the business without Protecnus. It is our operational foundation.”
Conclusion
Deuma’s case demonstrates that with the right tools, a service business can transform its operations, improve customer relationships, and scale with control and efficiency. Protecnus and Itestor not only helped organise processes, but became the digital engine of a business that continues to grow.
