Custom extranet, custom software development

Custom corporate extranet development

Good communication with your customers, suppliers, partners or other organisations is essential to ensure efficient and sustainable management.

We are custom developers with experience building applications designed to optimise internal and external processes. That is why we believe a well-structured extranet makes all the difference, bringing real added value versus the competition.

Implementing an extranet or an online customer area encourages fast information exchange and the transfer of large volumes of data between customers and the company. However, due to the confidential nature of this information, this network must remain private and accessible only to authorised people linked to your organisation—thereby ensuring data protection.

Beyond simply complying with regulations, an extranet that ensures perfect synchronisation with your stakeholders and strengthens your relationships in a smooth and efficient way becomes an essential tool for your company.

That is where we come in: by developing a custom corporate extranet capable of filling gaps, automating repetitive processes and integrating easily with your other tools.

Today, data is value: used well, it moves your entire business forward.

For more than 15 years, we have specialised in custom software development, perfectly tailored to our clients’ needs. We design each solution anticipating future evolutions, thereby reducing improvement costs. With fully proprietary development, we adjust every detail of how it works to your requirements.

You have the idea, we turn it into reality.

Our custom extranet development approach

At illusion Studio, we have chosen to work with a methodology that allows our clients to actively participate in every stage of their project. We leave behind the old approach where developers built the application on their own, and the client only saw the result once the work was finished.

We apply our own methodology, inspired by agile methods such as SCRUM and KANBAN—SCRUM for planning, and KANBAN for tracking. Thanks to this combination, we ensure direct contact, constant collaboration, better forecasting and precise execution.

The benefits of a custom extranet for your company

Agile information management

We analyse your repetitive processes to rethink them in order to save time and streamline your management. We create automated and configurable processes capable of eliminating unnecessary manual tasks.

Our principle is simple: if we develop a custom extranet, it must bring value.
No licence costs, no user limits

Our custom extranet developments are designed with no user limits and no licence costs. You only pay for our real work. With our experience, we also advise you on the best way to reduce operational costs through your extranet. And, as always with our custom developments, you own the code.
Give value to your data

It is no longer just about displaying lists of documents, tasks, employees, suppliers, or limiting yourself to basic view-only data. The challenge is to go further, give value to data, and analyse each resource, its history and its real contribution. This is how you get a tool that is both lightweight and useful.

We help you define the right criteria so that this value becomes a strategic asset within your company.
A custom extranet for every company, built for the future

Since 2008, every custom extranet project we deliver has been unique and different. Our model is not based on reusing existing developments, because every company and every extranet are unique. It is based on creating long-lasting projects designed to evolve over time.

A useful, high-quality project that is truly used is naturally easier to grow. Above all, we build long-term trusted relationships with our clients. Because a satisfied client is our best recommendation.
Integrations with ERP and other software

We are experts in integrating with external platforms that have APIs or connectivity features. And since we develop bespoke solutions, we can also build your own APIs so other applications can connect to your extranet. The result: a more open, powerful and scalable system.
