Challenges
Field Operations
Workers on construction sites needed a mobile application functioning both online and offline to avoid blocking tasks in poor connectivity zones.
User Experience
The app had to remain extremely simple and fluid for on‑site usage—quick daily task overview, minimal taps, and intuitive navigation to client contact and location.
Need for Complex Document Generation
Activities like leak detection required long, tedious reports. Automating report generation after task completion saved roughly 2 hours per report.
Multi-Company
The client owned several companies in the sector. Centralizing all entities in a single database enabled cross‑company reporting and unified operational oversight.
Productization
To recoup investment, the application needed to be licensable to similar companies—meaning modular extension points and customization hooks were essential.
Data Management
Data structure and hosting required careful design to ensure scalability and consistent performance as usage grew.
The Features
To address the challenges, a custom ERP was built to tightly link office operations and field execution.
Invoicing & Task Management
Automated work order creation, real‑time project tracking, and streamlined invoicing improved cash flow and reduced administrative friction.
Maintenance Contracts
A dedicated module handled long‑term service agreements, ensuring timely renewals and limiting revenue leakage.
Document Generation & Reporting
Automated creation of contracts, compliance documents, and rich operational reports reduced manual document + invoice preparation time by ~2.5 hours per admin staff per day.
On‑Site Task Management
Workers viewed an ordered list of daily tasks with direct shortcuts to call or navigate to the client. A guided, fool‑proof flow ensured mandatory information was captured before task closure.
