What SaaS MVP Development Actually Delivers — And What It Skips

Your MVP ships in 4–6 weeks with auth, billing, and a working dashboard—not a prototype riddled with placeholder screens. We build on Next.js, Supabase, and Stripe because your stack needs to survive first revenue, not collapse when you hit your first hundred users. Multi-tenant row-level security ships from day one so you're not retrofitting data isolation after a breach scare. Subscription webhooks are tested against failure states most boilerplates ignore—silent charge failures, plan downgrades during billing cycles, seat enforcement when a user invites their sixth teammate. You own the repo, deploy to Vercel or your own infra, and your team can extend it without decoding someone else's framework. This isn't about cramming features—it's about shipping the core loop that lets you charge money and gather feedback before your runway burns out.

Où les projets échouent

No-code tools hit a wall around $5K–$10K MRR Replatforming mid-growth is expensive, slow, and burns runway you can't afford to waste.
Boilerplate starters skip multi-tenancy and row-level security When data leaks between tenants, you lose trust fast — and the liability exposure is real.
Stripe looks straightforward until webhooks start failing silently Customers get charged but lose access. Or they get free access indefinitely. Neither is good.
Hiring a full-stack team for an MVP eats 3–6 months of runway You run out of money before you've even validated whether anyone wants the thing.
Without audit logging or an admin panel from day one, support tickets pile up and your team has zero visibility into what's actually happening with user accounts. Support tickets pile up with zero visibility into user state
Transactional emails are almost always an afterthought Users miss onboarding steps, don't see trial expiration warnings, and churn over billing failures that a simple email would've prevented.

Conformité

Multi-Tenant Row-Level Security

Supabase RLS policies enforce data isolation at the database level. Doesn't matter what the application does — one tenant can't read or touch another tenant's data.

Stripe Webhook Resilience

Idempotent webhook handlers with signature verification and retry logic. Failed events get logged and reprocessed automatically. No silent billing failures, no manual digging through logs.

Authentication & Authorization

Supabase Auth with magic links, OAuth providers, and role-based access control. Team invitations, seat management, and session handling are built in from day one — not bolted on later.

Subscription Billing Engine

Monthly, annual, and usage-based billing through Stripe with customer portal integration. Proration, trial periods, and dunning flows all handled correctly, not approximately.

Audit Logging

Every state change — plan upgrades, permission changes, data modifications — gets logged with a timestamp, the actor who made it, and the relevant context. Essential for debugging. Increasingly necessary for compliance.

Transactional Email via Resend

Welcome sequences, trial expiration warnings, billing receipts, and password resets. Templated, branded, and actually deliverable — not landing in spam folders.

Ce que nous construisons

Build multi-step onboarding that activates your core feature in under 90 seconds

Your users finish onboarding and hit value in one session instead of abandoning mid-flow

Ship a dashboard with real-time usage metrics your users check daily

Your dashboard becomes the daily login destination that drives retention and expansion

Deploy an admin panel with user impersonation and subscription override controls

Your support team resolves account issues in 60 seconds instead of escalating to engineering

Integrate Stripe with webhook handling that survives payment failures and retries

Your billing runs silently—customers stay active through card failures and plan changes

Enforce team seats and role permissions tied directly to subscription tier

Your team collaboration features scale from solo founders to 20-seat enterprise trials

Expose API routes with rate limiting and key management ready for third-party tools

Your API attracts integration partners and power users without a second build phase

Notre processus

01

Product Scoping

We map your core user journey, define the data model, and nail down the billing logic before anything gets built. You get a technical blueprint and a Figma wireframe kit before a single line of code gets written.
Week 1
02

Infrastructure & Auth

Supabase project setup with RLS policies, authentication flows, Stripe account connection, and a CI/CD pipeline on Vercel. The foundation ships first.
Week 2
03

Core Features & Billing

User dashboard, onboarding flow, subscription billing with webhook handlers, and transactional email templates. This is where the product actually starts to feel real.
Weeks 3–4

Questions fréquentes

Comment cela diffère-t-il d'utiliser un boilerplate SaaS ou un kit de démarrage ?

Les boilerplates vous donnent un point de départ mais sautent les parties difficiles — RLS multi-tenant, résilience des webhooks, outils d'administration et votre logique métier réelle. Nous livrons une application prête pour la production construite autour de votre modèle commercial spécifique, pas un modèle rempli de commentaires TODO où le code important devrait être.

Les fondateurs non techniques peuvent-ils travailler avec vous ?

Absolument. Nous gérons toutes les décisions techniques et les traduisons en langage clair lors des synchronisations hebdomadaires. Vous vous concentrez sur les utilisateurs et le modèle commercial. La base de code que nous vous remettons est accompagnée d'une documentation suffisamment claire pour que n'importe quel développeur senior puisse la reprendre et l'utiliser.

Que se passe-t-il quand j'ai besoin de me développer au-delà du MVP ?

L'architecture est conçue pour évoluer avec vous. Next.js App Router sur Vercel se met à l'échelle horizontalement. Supabase gère des millions de lignes avec un indexage approprié. Stripe gère n'importe quel volume de facturation que vous lui lancez. Quand vous êtes prêt pour les fonctionnalités V2, nous pouvons poursuivre l'engagement ou confier à votre équipe interne — selon ce qui a le plus de sens.

Suis-je propriétaire du code source ?

Oui, complètement. Le référentiel se trouve dans votre organisation GitHub dès le premier jour. Vous possédez chaque ligne de code, chaque migration de base de données et chaque configuration de déploiement. Aucun frais de licence, aucuns frais de plateforme récurrents de notre part, aucune dépendance vis-à-vis du fournisseur.

Comment gérez-vous les défaillances de webhook Stripe ?

Chaque endpoint webhook vérifie la signature de Stripe, traite les événements de manière idempotente et enregistre les défaillances dans votre pile de monitoring. Nous intégrons la logique de retry et la gestion des dead-letter pour que les événements échoués soient détectés et retraités — pas silencieusement supprimés. Ensuite, nous testons le tout par rapport à l'horloge de test de Stripe pour couvrir les cas limites comme les frais échoués et les changements de plan en cours de cycle.

Qu'est-ce qui est inclus dans le support post-lancement de 30 jours ?

Corrections de bugs, problèmes de flux de facturation, support de déploiement et ajustements mineurs basés sur les premiers commentaires des utilisateurs. Nous surveillons les taux d'erreur et la santé des webhooks au cours de ce premier mois critique. Ce n'est pas un module complémentaire payant — c'est inclus dans chaque engagement SaaS MVP parce que les 30 premiers jours surfacent toujours des cas limites. C'est juste comme ça que ça fonctionne.
