SaaS product development — MVP in 6 weeks

From idea to first paying users: MVP scope cut, Stripe/LiqPay billing, multi-tenancy, product metrics, iterations after launch.

When outsourced development is the right call

Selling a subscription product? You're in the right place. Outsourcing works when the hypothesis is still unproven and paying for a full in-house team is premature; when you need a first release in 6 weeks to show an investor or first customers; when you don't have an in-house engineering team, or it's tied up on the core product.

When outsourcing isn't the right fit

If you already have your own dev team and just need hiring help — that's not us. If the budget doesn't allow for custom development, we'll honestly recommend no-code for a first demand test. And if you need a portal or dashboard for your own business — that's web app development.

What we do

Three stages of SaaS development: MVP, launch, iteration

  • MVP from scratch

    Scope cut: what makes the first release, what goes to the backlog without hurting the hypothesis. Sign-up, roles, core action, billing — six weeks. Not a year of "full product," but the minimum you can sell.

  • Billing and multi-tenancy

    Stripe/LiqPay, trials, plans, invoices. Tenant data isolation is the most expensive thing to retrofit later. We build multi-tenancy in from day one, not "add it later."

  • Iterations after launch

    Activation and retention metrics, A/B tests, data-driven growth instead of gut feeling. Launch isn't the end of the project — it's the start of the next sprint.

What's included

Turnkey product scope

In SaaS development, shipping code is half the job. We close the full loop: from MVP spec to post-launch metrics

  • Multi-tenant architecture — tenant data isolation at the database schema level; no customer ever sees another's data.
  • Billing and subscriptions — Stripe, LiqPay, trials, plans, invoices, MRR data; test mode from the first sprint.
  • Auth, roles, invitations — workspace model: owner, admins, members; OAuth and 2FA as needed.
  • Product metrics from day one — activation events, retention, onboarding funnel; a dashboard for decision-making.
  • Product admin panel — plans, users, feature flags without a developer in the loop.
  • CI/CD, staging, monitoring — automated pipeline, Sentry or equivalent; staging environment after every sprint.

Stack

We pick the technology for the product, not out of habit

Stack fit to SaaS needs: multi-tenancy, subscriptions, metrics. Already have a team writing in a different stack? We'll tell you honestly what can carry a subscription model and multi-tenancy, and what can't.

  • Next.js
  • TypeScript
  • Node.js
  • Python
  • PostgreSQL
  • Redis
  • BullMQ
  • Stripe
  • LiqPay
  • OpenAI API
  • Anthropic API

How we ship an MVP

MVP in six weeks — then your first paying users

  1. Product call — 30 minutes

    Hypothesis, audience, first paid action, what already exists (designs, competitors, MVP look-alikes). We record the call and send notes to your inbox the same day. Deliverable: shared understanding of the product plus a rough MVP scope.

  2. MVP specification

    Scope cut: what we trim without hurting the hypothesis, what goes to the backlog. ER diagram, API contract, tenant model, wireframes of core screens. Deliverable: a fixed first-release scope plus timeline and acceptance criteria. We don't quote a fixed price before the spec.

  3. Development in sprints

    Two-week sprints, a staging demo at the end of each one. Progress you can see in a browser, not a slide deck. Deliverable: a working product on staging; billing connected to Stripe test mode from the first sprint.

  4. Launch to first users

    Deploy to production, billing goes live, metrics start recording from the first real user. Release checklist: domains, backups, error alerts. Deliverable: a live product ready to take payments from day one.

  5. Iterate on the metrics

    What activates users, where they drop off, which features move retention — growth after launch driven by data, not gut feeling. This is a separate paid stage, not "free support." Deliverable: a retainer for iterations, or a full handoff to your in-house team with complete documentation.

More detail

SaaS product development: multi-tenancy and billing from day one

SaaS development differs from a regular web app not in the stack, but in the architectural decisions that either get built in from day one or become expensive later. Multi-tenancy, billing and product metrics can't be "added later": trying to graft them onto a finished monolithic codebase means rewriting the product from scratch. So when a founder comes to us with a hypothesis, we don't start with the UI — we start with the tenant model and the Stripe webhook architecture.

An MVP in 6 weeks isn't a marketing slogan, it's a concrete scope: sign-up and authentication (OAuth or JWT), a workspace model with roles (owner, admin, member), the product's core action, subscription billing with a trial. Anything beyond that goes to the backlog. The scope cut is the key tool here: trimming without hurting the hypothesis is harder than adding features later. Founders launching a SaaS product for the first time usually underestimate how long it takes to build billing correctly — webhook lifecycle, dunning, invoice PDFs, MRR data. That's not two days of work. Better to build it right once than rewrite it under pressure from your first customers.

After launch, the priority is not breaking what's already selling. That's why CI/CD and staging aren't optional — they're part of the process from the first sprint. Every two weeks: a staging demo, QA on real scenarios, automated tests on critical logic (the billing module, access rights, tenant isolation). Nothing reaches production without signed-off acceptance criteria.

Iterations after launch are a separate stage, not "free support." Product metrics: what share of sign-ups reach the first paid action, where the onboarding funnel sags, which features correlate with retention. Growth driven by this data, not by gut feeling, is where most SaaS products either start growing or get stuck. If you need an AI feature on top of the core product, we connect it through the OpenAI or Anthropic API on the same stack, without rebuilding the architecture. AI solutions for business →

We pick the stack for the specifics of SaaS: Next.js for the front end and the product's marketing pages, Node.js or Python for the API and billing logic, PostgreSQL with tenant isolation, Redis for queues and background jobs. Hosting — Vercel + Neon or a Hetzner VPS, depending on budget and GDPR requirements. If you already have part of the stack in place, we'll tell you on the call what's worth keeping and what to rebuild.

SaaS development isn't staff augmentation and it isn't "write code to a spec." It's collaborative work on a product, where the contractor owns the architecture, billing and first live release, and the founder owns the hypothesis and first contact with the market. If that's your situation, a 30-minute call will give you an MVP scope and an honest range for building a SaaS product for your market. Discuss your idea on a call →
