SaaS Product Development Services
A SaaS product is more than an app: it is tenancy, billing, onboarding, permissions, usage limits, admin tooling and analytics — the invisible machinery that decides whether the business scales or leaks. StellarCode has built this machinery repeatedly, and ships our own SaaS products, so we design for the metrics that matter: activation, conversion and churn.
We take founders and companies from idea to first paying customer, and existing products from fragile to scalable. Stripe subscriptions, multi-tenant data isolation, role hierarchies, feature flags and usage metering are solved problems in our codebase patterns — you pay for your product, not for us to rediscover the basics.
What you get
Multi-tenant architecture
Clean tenant isolation at the database and API layer — the foundation that makes enterprise deals and audits possible later.
Subscriptions & billing
Stripe plans, trials, upgrades, proration, dunning and invoices — revenue plumbing that reconciles to the cent.
Onboarding & activation flows
Signup, workspace creation, invites and guided first-run experiences engineered to get users to value fast.
Admin & internal tooling
Back-office panels for your team: customer lookup, plan overrides, feature flags, audit logs and support tooling.
Usage metering & limits
Per-plan quotas, rate limits and usage-based billing hooks that make pricing pages true.
Product analytics
Activation funnels, retention cohorts and feature-usage tracking baked in from launch, not bolted on after.

SaaS Product Development — FAQ
How much does it cost to build a SaaS product?
A lean first version with tenancy, subscriptions and one sharply defined core workflow typically runs $12,000–$35,000 with StellarCode. The same scope is routinely quoted at $60,000–$150,000 by US or European agencies. We fix the quote before starting, and structure the roadmap so revenue features ship first.
How long until my SaaS can take paying customers?
Usually 8–14 weeks for a first sellable version. We deliberately sequence the build so billing, signup and the core workflow are live early — meaning you can charge real customers while later features are still in development.
Can you rescue or scale an existing SaaS product?
Yes. Common rescues include single-tenant codebases that need proper tenant isolation, billing systems that drift from Stripe reality, and performance collapses at growth. We start with an architecture audit, stabilise the highest-risk areas, then refactor incrementally — keeping the product live and selling throughout.
Do you sign NDAs and how is IP handled?
We sign your NDA before any product discussion, and every contract assigns full IP ownership — code, designs, documentation — to you. Repositories, cloud accounts and the Stripe account are all created under your ownership from day one, so nothing about the business is hostage to the vendor.
