Quelle différence entre un site web classique et une plateforme sur mesure ?

Un site classique présente votre entreprise. Une plateforme sur mesure intègre acquisition, automatisation, espaces sécurisés et outils métier connectés à votre activité.

Peut-on connecter la plateforme à notre CRM ou ERP ?

Oui. Nous créons des ponts API bidirectionnels pour que votre plateforme communique en temps réel avec Salesforce, HubSpot, Sage, ou vos outils propriétaires.

Peut-on intégrer un espace client sécurisé ?

Absolument. Nous développons des espaces membres avec gestion fine des droits, accès aux factures, suivi de dossiers et messagerie support.

Est-ce que Centralys prend en compte le SEO ?

Le référencement naturel est au cœur du code : structure propre, vitesse de chargement optimisée et balisage sémantique pour dominer Google.

Combien de temps faut-il pour développer une telle plateforme ?

Un MVP fonctionnel est généralement lancé en 8 à 12 semaines, suivi de phases d'améliorations continues selon vos retours terrain.

Sommes-nous propriétaires de notre plateforme ?

Oui. Contrairement aux abonnements SaaS, vous possédez votre code source et votre base de données. C'est un actif valorisable au bilan de votre société.

The reality

Most websites cost money.
Very few actually create value.

Untapped traffic

Visitors come… then leave without ever being captured or qualified.

Zero automation

Every lead, every quote, every follow-up still relies on human action.

Scattered data

Site, CRM, and business tools don't talk to each other. Information gets lost along the way.

Limited experience

No client portal, no self-service: your clients depend on your business hours.

Fragile acquisition

Dependency on Ads without an SEO strategy or robust conversion funnel.

Blurry tracking

No real visibility on your platform's ROI in real time.
