SaaS Application Development

The gap between a working product and a sellable one is mostly plumbing: tenants, roles, billing, and the admin screens that let you support a customer without opening a database client.

What you get

What the work actually includes

  • Multi-tenancy from day one

    Tenant isolation decided and enforced at the data layer, because retrofitting it later is a rewrite rather than a refactor.

  • Subscriptions and billing

    Plans, trials, upgrades, proration, failed payments, and dunning, wired to Stripe and reconciled against what the product actually grants.

  • Organisations and roles

    Invitations, seats, and role checks enforced server-side, with an audit trail on anything that matters.

  • Onboarding that works unattended

    Self-serve signup through to first value without a sales call, which is what makes the lower price tiers viable at all.

  • Support tooling

    An internal admin to impersonate a user, adjust a plan, and read the event history, so support does not become an engineering ticket.

  • Usage analytics

    Product usage tracked from day one against the metrics that actually predict churn and expansion, not a generic dashboard nobody opens.

  • A public API, if customers need one

    Documented, versioned, and rate-limited per plan tier, for the segment of customers who want to integrate rather than just log in.

Questions

SaaS Development, answered plainly

Row-level tenancy or a database per tenant?

Row-level with enforced tenant scoping for most products: simpler to operate and migrate. A database per tenant when a customer contractually requires isolation, or when one customer's data volume distorts everyone else's queries.

Can you add billing to a product we already have?

Usually yes, and it is well-bounded work. The hard part is rarely Stripe. It is deciding what each plan grants and enforcing that in one place instead of fifteen.

Do you build the marketing site too?

Yes, and we prefer to. The same application can serve the marketing pages and the product, which means one deploy, one design system, and no drift between what the pricing page promises and what the app enforces.

How long does it take to build a SaaS MVP?

Eight to twelve weeks for a first paid version with tenancy, one subscription tier, and the core workflow, working week by week so you see something running rather than a demo at the end. Multiple plan tiers, roles, and an admin surface extend that, and we scope those additions separately rather than folding them into the MVP estimate.

Can you build usage-based billing, not just flat subscriptions?

Yes. Metered usage reported to Stripe Billing against a plan's included allowance, with overage charged automatically, is a well-understood pattern. The work is mostly in accurately tracking and reporting the usage event itself, which we scope against your specific metric before quoting the billing side.

What else we build

Most projects need more than one of these, and they are usually cheaper together than sequenced apart.
