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.

Waar projecten falen

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.

Compliance

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.

Wat we bouwen

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

Ons proces

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.

Veelgestelde vragen

Hoe verschilt dit van het gebruik van een SaaS boilerplate of starter kit?

Boilerplates geven je een startpunt maar slaan de moeilijke onderdelen over — multi-tenant RLS, webhook robuustheid, admin tooling en je daadwerkelijke product logica. We leveren een production-ready applicatie gebouwd rond je specifieke bedrijfsmodel, niet een template vol TODO-opmerkingen waar de belangrijke code zou moeten staan.

Kunnen niet-technische oprichters met je samenwerken?

Absoluut. We nemen alle technische beslissingen en vertalen ze in begrijpelijk taal tijdens wekelijkse syncs. Jij richt je op gebruikers en het bedrijfsmodel. De codebase die we afgeven, komt met documentatie die duidelijk genoeg is zodat elke senior developer het kan oppikken en ermee aan de slag gaan.

Wat gebeurt er als ik voorbij de MVP moet schalen?

De architectuur is gebouwd om met je mee te groeien. Next.js App Router op Vercel schaalt horizontaal. Supabase handelt miljoenen rijen aan met juiste indexering. Stripe handelt elk billing volume aan dat je ertegenaan gooit. Als je klaar bent voor V2-functies, kunnen we de samenwerking voortzetten of overgeven aan je interne team — wat het meest zinvol is.

Ben ik eigenaar van de broncode?

Ja, volledig. De repository bevindt zich van dag één in je GitHub-organisatie. Je bent eigenaar van elke regel code, elke database migratie en elke implementatieconfiguratie. Geen licentiekosten, geen terugkerende platformkosten van ons, geen vendor lock-in van welke aard ook.

Hoe pak je Stripe webhook-fouten aan?

Elk webhook-eindpunt verifieert Stripe's handtekening, verwerkt events idempotent en registreert fouten in je monitoring stack. We bouwen retry-logica en dead-letter handling in zodat mislukte events worden opgemerkt en opnieuw verwerkt — niet zwijgend weggegooid. Vervolgens testen we het alles tegen Stripe's test clock om randgevallen af te dekken, zoals mislukte betalingen en mid-cycle planwijzigingen.

Wat is inbegrepen in de 30-daagse ondersteuning na lancering?

Bugfixes, billing flow problemen, implementatieondersteuning en kleine aanpassingen op basis van vroege gebruikersfeedback. We monitoren foutpercentages en webhook-gezondheid gedurende die kritieke eerste maand. Dit is geen betaalde add-on — het is inbegrepen in elke SaaS MVP engagement omdat de eerste 30 dagen altijd randgevallen naar boven brengen. Dat is gewoon hoe het werkt.
