DURATION
Triangle Procurement, founded in 2020, helps Belgian SMEs manage energy procurement and optimization. Their Excel-based workflows limited efficiency and scalability, making it difficult to run accurate simulations or generate timely reports.
Linnify developed a web-based energy optimization tool that allows consultants to analyze energy data, simulate solar and battery storage scenarios, and generate professional reports in minutes. The platform streamlined operations, reduced errors, and positioned Triangle Procurement as a leader in Belgium’s energy consultancy market.
Energy consultancy firms often struggle with manual, error-prone processes, scaling across multiple clients, and time-consuming reporting. Running complex simulations in Excel makes it difficult to deliver precise, data-driven insights quickly.
Triangle Procurement needed a solution that automated scenario modeling, simplified reporting, and ensured usability for non-technical consultants, all while adapting to Belgium’s strict energy regulations.
The primary target market for the Triangle Procurement platform is Belgium, where the company operates exclusively. Focused on the energy consultancy sector, the tool is designed to support small and medium-sized enterprises (SMEs) in optimizing their energy consumption and investment strategies. By offering data-driven insights tailored to local energy market dynamics, the platform empowers Belgian SMEs to make smarter, more sustainable energy decisions.
The platform was developed with a strong understanding of Belgium’s regulatory environment, including the energy tariffs, incentives for solar and battery storage investments, and national requirements for energy reporting.
Cultural factors also played a role: Belgian SMEs often value precision, data transparency, and practical tools that save time. The tool’s user experience was therefore designed to be intuitive, results-oriented, and highly compatible with the day-to-day workflow of energy consultants and small business managers in Belgium.
Triangle Procurement's reliance on Excel spreadsheets posed several challenges:
These limitations hindered their ability to offer timely and precise recommendations to clients.
The Triangle Procurement app effectively solved the client's core problem by replacing their fragmented, Excel-based workflow with a centralized and automated platform tailored for energy scenario simulation.
Instead of juggling spreadsheets to model energy consumption and solar investment outcomes, users now benefit from a seamless web experience. The platform allows them to easily manage customer portfolios, upload CSV energy data, and configure complex scenarios in just a few clicks.
It then instantly calculates cost savings, energy output changes, and return on investment for solar and battery installations, all with clear results expressed both in euros and kWh.
Previously manual tasks such as running different scenarios, adjusting assumptions, or compiling reports for clients were now done in minutes instead of hours. By integrating semi-automated reporting with Looker Studio, the platform also eliminated redundant formatting work, offering stakeholders polished, exportable visuals with zero additional effort.
The result is a smarter, faster, and more reliable decision-making tool that enhances Triangle Procurement’s ability to serve clients and remain competitive in Belgium’s evolving energy landscape.
From concept to deployment, Linnify managed the full-cycle development of Triangle Procurement’s energy optimization platform in under three months, successfully transforming a fragmented Excel-based workflow into a modern digital solution. The project was delivered on time and within scope by the end of August 2024, proving the effectiveness of Linnify’s lean and validation-driven approach.
The challenge was not just to build a web application, but to design a scalable SaaS platform that could handle complex energy consumption data, run accurate solar and battery investment simulations, and generate client-ready reports in minutes. By acting as both a strategic partner and a technical execution team, Linnify ensured that the product would not only digitize existing processes but also unlock new levels of efficiency for Belgian SMEs.
This role required balancing domain-specific expertise in energy management with cutting-edge web development practices. Our team worked closely with Triangle Procurement’s founder to capture every business rule embedded in the old system and translate it into a user-friendly, future-proof application.
The UX/UI team designed intuitive user flows for tasks such as scenario creation and data uploads, focusing on clarity for non-technical users. Development teams then built a robust web application using Next.js and TypeScript, integrating CSV processing, Google Login authentication, and custom solar/battery optimization models.
To streamline client reporting, the app was connected with Looker Studio, enabling semi-automated, professional reports. Throughout the process, agile project management and weekly check-ins ensured timely delivery and smooth collaboration.
The transition from an Excel-based system to a web application has empowered Triangle Procurement to offer enhanced services to its clients. The new platform not only streamlines internal processes but also provides clients with actionable insights into their energy consumption and potential savings.
The Triangle Procurement project reinforced Linnify’s ability to turn highly technical, spreadsheet-based workflows into modern, scalable platforms. By working closely with a founder deeply immersed in the energy procurement space, our team sharpened its understanding of domain-specific logic, from dynamic pricing contracts to solar and battery ROI simulations.
This collaboration taught us how to:
The project also reaffirmed our belief in fast, high-quality delivery: shipping a full-featured, production-ready energy platform in less than three months. It proved the value of lean product development, hands-on stakeholder collaboration, and maintaining a sharp focus on business outcomes throughout the design and build process.
Triangle Procurement replaced time-consuming Excel workflows with a custom-built energy optimization platform that automates simulations for solar and battery investments, improves data accuracy, and drastically reduces manual reporting efforts.
The platform analyzes historical energy usage and simulates solar panel and battery ROI scenarios, helping SMEs make smarter, data-backed investment decisions based on local tariffs, incentives, and consumption patterns.
Yes. The solution integrates with Looker Studio to deliver visually rich, exportable energy reports, eliminating the need for manual formatting and enabling consultants to generate reports in minutes instead of hours.
Linnify developed and launched the full-featured web application in under 10 weeks, transforming a manual spreadsheet-based process into a scalable digital product ready for real-world use.
Absolutely. The app features a clean, intuitive interface designed for energy consultants and business managers, no coding or technical knowledge required to run simulations, upload data, or manage client portfolios.
The platform was built using Next.js, TypeScript, and integrated with Google Login and Looker Studio. It also supports CSV uploads, automated calculations, and custom energy scenario modeling tailored to Belgian regulations.
Linnify led the entire product lifecycle, from discovery and UX to development and delivery, demonstrating its ability to turn domain-specific, spreadsheet-heavy processes into scalable web platforms that drive business growth and operational efficiency.
