User management
Roles, statuses, information, renewals: everything is centralized in a clear and secure system.

We design custom user portals and extranets for your customers, suppliers or members. A space connected to your IS where everyone accesses their documents, tracks their requests and gains autonomy.
Create my portal


Your customers, suppliers or members deserve simple and secure access to their information. A custom portal allows them to view their data, track their files and interact with your services without soliciting your teams.
We design personalized spaces where each user finds exactly what they need. No more emails to request an invoice, calls to know the status of an order or misplaced documents.
Before we design a single screen, we list the questions your users ask you today by phone or email. The portal has to answer them on its own.
A custom extranet rarely lives alone: it connects to your ERP, CRM or accounting software through APIs to display the right data in real time. When the portal also needs to host contractual or technical documents, we back it with an electronic document management layer that cleanly handles versions, access rights and retention periods.
Our fully remote team works across France on B2B client areas, industrial supplier portals and federation member spaces alike. Project governance is adjusted to the size of your organisation: close-knit workshops for an SME, structured steering committees for a local authority or public institution.
Roles, statuses, information, renewals: everything is centralized in a clear and secure system.

Adding a document, registration, request... with built-in automation and traceability.

Documents, administrative files, reports, images, accessible according to profiles and roles.

Allow your users to exchange directly in the platform and receive alerts in real time.

Connection to your CRM, business database, internal IS, document tools or professional directories.

We identify your different types of users, their specific needs and their journeys. A B2B customer doesn't have the same expectations as a member or a supplier. This deep understanding guides the entire design. A project scoping round lets us formalise target journeys before development kicks off.
Each profile accesses a space adapted to their role. Relevant dashboards, quick actions, contextual information: we create a tailored experience that simplifies your users' daily lives. We validate the layout through prototyping tested with a few representative users before investing in full development.
Robust authentication, fine-grained rights management, action traceability: your portal protects sensitive data while remaining easy to use. GDPR compliance built in from the design phase. Application security best practices are applied at every step of development.
A simple client portal with authentication, a dashboard and access to a few business data points starts around €18k–€30k. A full custom extranet with multiple profiles, workflows, IS integrations and a mobile app sits between €50k and €120k. The MoSCoW method helps prioritise features to stay on budget without sacrificing the critical parts of the user journey.
For a first version usable by a pilot group, expect 3 to 5 months depending on complexity. We first ship an MVP with the essentials (login, data consultation, main actions), put it in the hands of real users, then extend the scope based on their feedback rather than assumptions.
Salesforce or HubSpot portals fit when your commercial logic maps onto their data model and standard permissions. A custom extranet makes sense when your users need very specific business actions (checking stock by warehouse, approving a purchase order with delegation rules, tracking a technical case) or when the IS integration goes beyond what packaged connectors offer.
A well-designed portal transforms the relationship with your users. They gain autonomy, find their information instantly and can act without waiting. Your brand image is strengthened.
For your teams, it means fewer repetitive requests, fewer manual tasks and more time for high-value requests. The portal becomes a privileged communication channel.
And unlike generic solutions, your portal follows your processes and evolves with your needs.
