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.

Dónde fallan los proyectos

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.

Cumplimiento

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.

Qué construimos

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

Nuestro proceso

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

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

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

Admin Panel & Polish

Internal admin tooling, audit logging, error monitoring, and UI polish. Every edge case in the billing flow gets tested against Stripe's test clock.

Week 5

Launch & Handoff

Production deployment, domain configuration, monitoring dashboards, and full documentation. Then we stick around for 30 days of post-launch support.

Preguntas frecuentes

¿En qué se diferencia esto de usar un boilerplate SaaS o starter kit?

Los boilerplates te dan un punto de partida pero omiten las partes difíciles — RLS multi-tenant, resiliencia de webhooks, herramientas de administración y tu lógica de producto real. Entregamos una aplicación lista para producción construida alrededor de tu modelo de negocio específico, no una plantilla llena de comentarios TODO donde debería estar el código importante.

¿Pueden trabajar contigo fundadores no técnicos?

Absolutamente. Manejamos todas las decisiones técnicas y las traducimos a lenguaje plano en llamadas semanales. Tú te enfocas en usuarios y el modelo de negocio. La base de código que entregamos viene con documentación lo suficientemente clara para que cualquier desarrollador senior la retome y continúe.

¿Qué sucede cuando necesito escalar más allá del MVP?

La arquitectura está construida para crecer contigo. Next.js App Router en Vercel escala horizontalmente. Supabase maneja millones de filas con indexación adecuada. Stripe maneja cualquier volumen de facturación que le lances. Cuando estés listo para características de V2, podemos continuar con el compromiso o delegar a tu equipo interno — lo que tenga más sentido.

¿Soy dueño del código fuente?

Completamente. El repositorio vive en tu organización de GitHub desde el primer día. Eres dueño de cada línea de código, cada migración de base de datos y cada configuración de despliegue. Sin cuotas de licencia, sin cargos de plataforma recurrentes de nuestra parte, sin bloqueo de proveedor de ningún tipo.

¿Cómo manejas los fallos de webhooks de Stripe?

Cada endpoint de webhook verifica la firma de Stripe, procesa eventos de forma idempotente y registra fallos en tu stack de monitoreo. Construimos lógica de reintentos y manejo de dead-letter para que los eventos fallidos se detecten y reprocesen — no se descarten silenciosamente. Luego lo probamos todo contra el reloj de prueba de Stripe para cubrir casos extremos como cargos fallidos y cambios de plan a mitad de ciclo.

¿Qué incluye el soporte de 30 días después del lanzamiento?

Corrección de errores, problemas de flujo de facturación, soporte de despliegue y ajustes menores basados en feedback de usuarios tempranos. Monitoreamos tasas de errores y salud de webhooks durante ese primer mes crítico. Esto no es un complemento pagado — está incluido en cada compromiso de MVP SaaS porque los primeros 30 días siempre sacan a la luz casos extremos. Así es como funciona.
