How did Agence Scroll unlock a SaaS AI business prototype?

Generate the start of an application on platforms like Hostinger Horizons, Lovable or v0 now takes a few minutes and provides an immediate feeling of power. You describe your idea, artificial intelligence executes, and an interface appears before your eyes. It is a revolution for the ideation phase that makes it possible to materialize a vision without writing a line of code. However, turning this visual sketch into a business tool that can manage complex processes, invoicing, and field teams is another reality. It is precisely at this critical stage, when the prototype reaches its technical limits and the “magic” of AI is no longer enough, that Agence Scroll intervenes to structure and perpetuate the product.

The illusion of ease and the wall of technical complexity

We are living in a fascinating time for entrepreneurs and creators of digital products. Application builders based on large language models are excellent for visualizing an idea in record time. They create the illusion of absolute ease. The founder describes his need in natural language and the tool generates screens, buttons, and forms. It's magical for a first visual draft or to convince potential investors of the relevance of a concept.

However, these tools often fail on a critical point which is deep business logic. A visual prototype, no matter how beautiful it may be, rarely has a professionally structured database. It's often an empty shell or a superficial data structure that's unable to handle the load of real business activity. Artificial intelligence, in its current form of instant code generator, is struggling to anticipate edge cases, business exceptions and management rules that make your business unique.

The problem inevitably arises as soon as one tries to connect this generated interface to the reality on the ground. As soon as it is necessary to manage separate user roles, such as an administrator with all the rights compared to a technician who only has to see his schedule, the model collapses. As soon as it is necessary to apply strict security rules on data access (Row Level Security), “all-in-one” generative AI reaches a wall of complexity. She can't guess what security architecture is needed to protect your customer data or trade secrets.

Scroll's approach to this situation is radically different. We do not consider that the work done by AI is useless, but that it is a functional model, not a finished product. We don't throw away the initial idea because it contains the customer's vision. On the other hand, we are “taking” the project out of the AI black box to rebuild it on an open and modular architecture. We use tools that keep control of code, intellectual property, and data. It's the only way to go from an impressive demo to a business that runs and bills.

The Cindra context: The fire safety requirement

To illustrate this necessary transition from prototype to industrial product, the example of Cindra is particularly telling. This company operates in a rigorous sector, that of the installation and maintenance of fire safety equipment. Their profession does not tolerate approximation. It involves interventions on site, the management of a critical equipment park (fire extinguishers, alarms, smoke extraction) and flawless administrative traceability for legal and insurance reasons.

The initial need was clear but technically demanding. Cindra needed to centralize the management of its customers, precisely map the intervention sites and monitor the status of the entire equipment fleet in real time. Until then, like many SMEs in this sector, the company juggled scattered tools, endless Excel files and paper reports that were often difficult to use once back in the office.

The manager, aware of the need to go digital, started by validating his intuition with a prototype generated on Hostinger Horizons. This first step was useful in confirming the value of the project and visualizing what the ideal tool could look like. However, the tool quickly proved to be unstable as soon as we wanted to inject the reality of operations into it. It was impossible to finely model the relationships between a customer, its multiple sites, and the equipment attached to each site. Managing technician tours was becoming a headache that the tool could not solve. The project was validated in the spirit of the founder, but completely blocked in technical execution. That's when Cindra called on the Scroll Agency to transform the trial.

Rethinking architecture for robustness

To unblock the situation, we did not try to “repair” the existing prototype, because its foundations were too fragile. We took the need back to the root to rethink the global technical architecture. The aim was not only to make the application work, but to make it maintainable, scalable, and secure over the long term.

Our first step was to separate the different layers of the application. In AI generators, everything is often mixed up (interface, data, logic). At Scroll, we apply strict development principles, even when using low-code technologies. So we separated the front-end (what the user sees), the back-end (where the data is stored), and the automations (what the application does).

The user experience (UX) was our first priority during the rebuild. We went from a standard generative design, often designed for desktop screens, to an interface designed for field efficiency. Fire safety technicians often work in difficult conditions. They are standing, sometimes on a ladder, in poorly lit areas or without a stable internet connection. Their hands are busy. A classic interface with small buttons and complex menus is useless in this context.

So we worked on a radical “Mobile First” UX. We've reduced the number of clicks required for each action. We've expanded the touch areas to make it easier to type on a tablet or smartphone. We have implemented smart forms that pre-fill known data to limit manual entry errors. The objective was to reduce the friction between the technician and the digital tool so that the application was perceived as an aid and not as an additional administrative constraint.

The Scroll Tech Stack: The Power of Open Source and Low-Code

To support this interface and guarantee the sustainability of the project, we have deployed a robust technical stack, proven on hundreds of SaaS projects. The choice of tools is crucial: they must be efficient today, but also allow the company to evolve tomorrow without having to rebuild everything.

Plasmic for interface and flexibility

We chose Plasmic to build the front-end of the application. Unlike traditional page builders, Plasmic is a visual tool that integrates deeply with modern code (React). It offers the speed of No-Code development while generating clean and exportable code. This means that Cindra is not a prisoner of the platform. Plasmic allows us to iterate very quickly on the interface. If a technician tells us that a button is misplaced, we can modify it and deploy the update in a few minutes. This agility is impossible with long and expensive traditional development, and impossible with an AI generator that doesn't allow for this level of pixel-perfect precision.

Supabase for data sovereignty

For data management, we opted for Supabase. It is a major strategic choice. Unlike the simplistic databases that are often integrated into all-in-one tools (which sometimes look more like improved spreadsheets than real databases), Supabase is a complete PostgreSQL instance. It offers industrial-level security.

For Cindra, this allowed us to set up extremely detailed access rights management. Thanks to Supabase's native RLS (Row Level Security) system, we were able to define precise rules: a technician can only see and modify the interventions assigned to him, while the manager has a global view. This security is managed at the level of the database itself, which makes the system inviolable, even in the event of a bug on the interface. Additionally, Supabase manages user authentication, ensuring that only authorized individuals access sensitive customer information.

n8n for operational intelligence

Finally, n8n has completed this system to manage all the backend logic and automation. It is the invisible engine of the application. Instead of writing complex, hard-to-maintain scripts for each action, we use n8n to visually draw workflows. It is this tool that connects the Supabase database to external services (PDF generation, email sending, electronic signature). It allows the company's business processes to be modified without touching the application code, offering incredible flexibility to adapt to Cindra's organizational changes.

The core of value: Automations and document workflows

The real power of a business SaaS does not lie in the beauty of its screens, but in its ability to automate time-consuming tasks. This is where the return on investment is created. Cindra's initial prototype could not handle the administrative complexity associated with fire safety. It was necessary to generate specific legal documents, with specific layouts, and have them signed. We put processes in place that AI alone could not structure.

Let's analyze the workflow we've implemented. It all starts with planning. An intervention is created in the office and assigned to a collaborator. Instantly, the technician receives the information on his mobile application. He no longer needs to go to the office to pick up paper cards.

On site, the technician carries out his verification mission. It scans equipment, checks checkpoints, takes photos of anomalies. The app works even if the network is fickle, syncing data as soon as the connection comes back up. It is at the end of the intervention that the “magic” of automation works.

As soon as the technician validates his intervention on the application, n8n detects this change in state. The workflow is triggered automatically. The system retrieves all the data entered (customers, equipment, equipment, observations, photos) and dynamically generates the expected documents: detailed maintenance reports, quotes for necessary repairs, or new contracts. These documents are generated in PDF format with a professional layout that respects Cindra's visual identity.

But we went further. The system then automatically sends these documents for electronic signature if necessary, or directly by email to the customer. The validation cycle is traced from end to end. We know when the document was sent, when it was opened, and when it was signed. What used to require hours of retyping in the evening or at the weekend, printing and mailing, is now done instantly, without any additional human intervention.

Results: A quantified operational transformation

The results of this redesign by Agence Scroll are concrete, measurable and have transformed the daily life of the company. Cindra has replaced a multitude of scattered tools and precarious Excel files with a single, centralized platform.

The most significant impact concerns productivity gains. By automating the production of reports and contract documents, we have reduced administrative time by 40% per case. For an SME, this is a colossal gain. This represents hours of work freed up every week for each technician and for administrative staff. This recovered time is now reinvested in tasks with higher added value: customer advice, commercial prospecting or technical training.

In addition to saving time, it is the reliability of the information that has taken a leap forward. Finally, the data is unique and reliable. There is no more loss of information between the field and the office, no more illegible or lost reports. The history of customers, sites and equipment is centralized in Supabase and accessible in real time. If a customer calls with a question about a past intervention, the answer is available in a few clicks. This responsiveness significantly improves Cindra's brand image and customer satisfaction.

Finally, the application is robust. It left the unstable prototype stage to become a technological asset of the company. It is able to absorb the growth of Cindra, the addition of new technicians or the opening of new agencies without requiring a technical overhaul. The data structure is healthy and ready to evolve.
