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.

Onde os projetos falham

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.

Conformidade

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.

O que construímos

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

Nosso processo

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
04

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
05

Launch & Handoff

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

Perguntas frequentes

Como isso é diferente de usar um boilerplate ou starter kit SaaS?

Boilerplates oferece um ponto de partida, mas pulam as partes difíceis — RLS multi-tenant, resiliência de webhooks, ferramentas de admin e sua lógica de produto real. Entregamos uma aplicação pronta para produção construída em torno do seu modelo de negócio específico, não um template cheio de comentários TODO onde o código importante deveria estar.

Fundadores não-técnicos podem trabalhar com vocês?

Absolutamente. Cuidamos de todas as decisões técnicas e as traduzimos em linguagem clara durante as sincronizações semanais. Você se concentra nos usuários e no modelo de negócio. A base de código que entregamos vem com documentação clara o suficiente para que qualquer desenvolvedor sênior pegue e execute.

O que acontece quando preciso escalar além do MVP?

A arquitetura foi construída para crescer com você. Next.js App Router no Vercel escala horizontalmente. Supabase manipula milhões de linhas com indexação adequada. Stripe manipula qualquer volume de billing que você jogar. Quando estiver pronto para recursos V2, podemos continuar o engajamento ou transferir para seu time interno — o que fizer mais sentido.

Sou dono do código-fonte?

Sim, completamente. O repositório fica na sua organização GitHub desde o primeiro dia. Você é dono de cada linha de código, cada migração de banco de dados e cada configuração de deployment. Sem taxas de licença, sem cobranças recorrentes de plataforma de nós, sem vendor lock-in de qualquer tipo.

Como você lida com falhas de webhook do Stripe?

Cada endpoint de webhook verifica a assinatura do Stripe, processa eventos idempotentemente e registra falhas na sua stack de monitoramento. Construímos lógica de retry e dead-letter handling para que eventos falhados sejam identificados e reprocessados — não silenciosamente descartados. Depois testamos tudo contra o test clock do Stripe para cobrir casos extremos como cobranças falhadas e mudanças de plano no meio do ciclo.

O que está incluído no suporte de 30 dias pós-lançamento?

Correções de bugs, problemas de fluxo de billing, suporte de deployment e ajustes menores baseados no feedback dos usuários iniciais. Monitoramos taxas de erro e saúde de webhooks através desse primeiro mês crítico. Isso não é um add-on pago — está incluído em cada engajamento de SaaS MVP porque os primeiros 30 dias sempre revelam casos extremos. É só assim mesmo.
