The realityA great SaaS idea isn't enough.
A great SaaS idea isn't enough.
You need a reliable, scalable product.
01
Poorly scoped product
Too many features upfront, not enough focus on user value.
02
Fragile architecture
A product that breaks at 1,000 users if the technical foundation is overlooked.
03
Unclear subscriptions
Plans and Stripe payments must be integrated cleanly from day one.

SaaS Project FAQ
Everything you need to know about building your SaaS.
From code ownership to scalability, we answer your strategic questions.
The budget varies depending on automation complexity, number of user roles, and third-party integrations (payments, APIs). We work in phases: a Minimum Viable Product (MVP) can start on a controlled budget to test the market before investing in a full version.
Yes. Unlike proprietary "No-Code" solutions or classic SaaS subscriptions, the source code developed by Centralys belongs to you. It's a major intangible asset that increases your company's value, especially during fundraising or resale.
A first functional product is typically delivered in 8 to 12 weeks. Our agile methodology gets core features online quickly to gather first feedback from real users.
We use highly secure multi-tenant architectures. Each client has their own isolated space. Data is encrypted and hosted on certified infrastructure (AWS, Google Cloud, or sovereign servers depending on your needs), fully GDPR compliant.
Absolutely. We natively integrate Stripe Billing or Chargebee to handle monthly/annual plans, trial periods, promo codes, automatic upgrades/downgrades, and PDF invoice generation for your customers.
Our tech stack is chosen for scalability. Whether you have 10 or 10,000 users, the infrastructure auto-scales to maintain optimal load speed without service interruption.
We offer maintenance contracts (managed services) including 24/7 monitoring, security updates, and evolution tickets to add new features over time without blocking your growth.
Yes, we develop documented REST or GraphQL APIs. This allows your SaaS to communicate with your customers' ecosystem (CRM, Slack, Gmail, ERP) or offer Zapier/Make integration to automate workflows.
It's a critical step. A SaaS with poor ergonomics won't be adopted. Our design team creates modern, pixel-perfect interfaces designed to reduce your end users' learning curve.
It's one of our core specialties. We audit your internal tool to extract its business logic and migrate it to a modern SaaS architecture, ready to be sold to peers or your market as a subscription.
We favor robust, long-lasting technologies (Node.js, React, Python, PostgreSQL). This ensures you'll always find developers able to take over or extend the code in the future.
Yes, systematically. You validate the clickable Figma prototype before a single line of code is written. This avoids user journey errors and secures your investment.
It's a frequent request. We can integrate AI models (OpenAI, Anthropic, custom models) for data analysis, automatic content generation, or predictive recommendations within your platform.
We implement fine-grained permission management (RBAC). Each user type only accesses data and features specific to them, with a personalized dashboard for their access level.
Proximity and business understanding. A SaaS isn't just a technical project — it's a business project. We speak your language, understand your profitability stakes, and deliver high-quality follow-up without communication friction.
