01 A booming solar market, run the way it always had been
The quote was a piece of paper
Solar was booming across the Benelux, and GreenChoice, a Belgian solar panel installation company, was growing with it. The way the work got sold, though, had not changed in years. Surveying a roof meant getting to the roof. Quotes were written out on paper, the way they had always been, and then they traveled: to the office, to the customer, into a folder somewhere. A customer weighing a serious purchase was handed a handwritten sheet and asked to decide from it.
None of this was unusual. It was how much of the industry worked, and that was exactly what Özgür Gedik and the GreenChoice team wanted to stop accepting. Every site visit that started from zero because nothing had been prepared in advance, and every quote that sat in someone's bag instead of in front of the customer, was operational drag the company paid for daily. In late 2023 they came to ETREXIO wanting the class of platform the market's software leaders sell, tools like Sollit and 2Solar, but built around how GreenChoice actually works.
02 Panel placement on satellite imagery, and the quote from the same screen
The roof, from orbit
We built GreenChoice a management platform where the sale starts from a satellite image. The planner pulls up the customer's roof, places the panels directly on the imagery, and works out the layout before anyone drives out. The site visit did not disappear; it changed shape. With the heavy preparation done up front from the imagery, visits got shorter and more focused, and GreenChoice saw satisfaction rise on both sides of the doorstep: customers got their time back, and the field team stopped re-measuring what a screen had already answered.
From that same screen, the quote takes shape. The system prepares it and sends it, so the numbers the customer sees come straight out of the platform rather than off a clipboard. What used to be a chain of paper, handwriting and hand delivery collapsed into a single flow: prepare from the imagery, confirm on site, prepare the quote, send it. One system holds all of it, which also means nothing gets lost between the roof and the sale.
- Panel placement on the roof directly from satellite imagery
- Heavy preparation moved up front, so site visits got shorter
- Quote preparation inside the platform, sent from the system
- An online quote the customer opens and reviews in the browser
03 European customers noticed immediately
The moment the paper disappeared
The reaction GreenChoice noticed first came from the customers. For years, deciding on a solar installation meant deciding from a handwritten quote. Now the customer gets a link and opens the quote online: clean, readable, reviewable whenever they want to look at it again.
Digitizing what used to be written on paper delighted their European customers. That is GreenChoice's own telling, and it matches what we see in every industry that still runs on paper: the first company that lets customers see their offer properly, on their own screen and their own time, feels a class above the competitor still handing over a sheet. The platform was built for GreenChoice's operations, but the customers felt it too.
04 The founder's own math on what the platform replaced
The outcome
The clearest measure of the platform came from GreenChoice's founder: thanks to the system, the team shrank by about 15 percent. Work that used to need people to carry it, from quote paperwork to chasing documents between office and field, ran through the platform instead. Site visits stayed part of the job, but with the preparation done up front from satellite imagery they got noticeably shorter, and both customer and employee satisfaction rose.
We are direct about this part of our work: when software makes a position unnecessary, that is the software doing its job. The project kicked off in late 2023 and was delivered within 2024, adopted across the operation, with customers opening their quotes online instead of unfolding them. The company was later wound down when its founders parted ways; while it ran, the platform carried the operation.
