SaaS Development

Multi-tenant SaaS platforms built right from sprint 1 — subscription billing that survives failed cards, auth with team management and SSO, audit logs that pass procurement, and the boring observability that means your customers find out before you do that something's slow.

The SaaS foundations we build into every project

  • Multi-tenancy from sprint 1 — schema-per-tenant or row-level, never bolted on later
  • Subscription billing with Stripe/Chargebee/Paddle — proration, dunning, failed-card retries
  • Auth via Auth0/Clerk/WorkOS — including SSO/SAML for enterprise customers
  • Team management — invites, role-based access, audit logs
  • Webhooks and a public API — almost every SaaS eventually needs them
  • Email infrastructure (Resend, Postmark) with transactional templates
  • Analytics and product metrics — PostHog or Amplitude wired in correctly
  • Status page and incident communication (Atlassian Statuspage or self-hosted)

What kills SaaS startups in year 2

The MVP gets built, you launch, you find product-market fit, you hit 50 customers — and then the system starts breaking under its own weight. The technical-debt patterns we see most often:

  • Shared database with no tenant isolation strategy — one tenant's bad query takes down everyone
  • Auth that was built quickly and now blocks SSO sales because retrofitting SAML is painful
  • No background job system — long operations live in the request thread and time out
  • Billing logic scattered across the codebase — every pricing change becomes a refactor
  • No event log — debugging customer issues means reading transaction logs by hand
  • Single-region hosting that becomes a performance issue when US customers arrive

Most of these become genuinely expensive to fix at scale. They cost almost nothing to do right at sprint 1 — that's the practical case for paying a senior team to build the foundations correctly upfront.

Our SaaS build process

Discovery + prototype (2 weeks)

Wireframes for every screen. Architecture diagrams. Data model. Pricing-model analysis. Fixed-price quote. You own all of this regardless of whether you proceed.

Sprint 1 — auth + billing scaffolding

Most teams build features first and bolt on billing/auth at the end. We do it backwards: by end of sprint 1 you have a deployed app with working signup, login, team creation, subscription billing, and audit logs. Then we build features on top of solid foundations.

Beta and friendly-customer launch

4 weeks of beta with 5–10 friendly customers before public launch. Real billing, real auth, real edge cases — bugs are fixed in beta where they cost you nothing reputationally.

SaaS development FAQ

Multi-tenant for almost any genuine SaaS — it's the only economical model when you have 50+ customers. The exceptions: enterprise customers with hard data-isolation requirements (sometimes regulated industries), or vertical SaaS where each customer's instance is heavily customised. We default to shared-database, schema-per-tenant or row-level isolation depending on the compliance posture.
On day 1 of public launch you need: subscription billing that handles failed cards gracefully, multi-tenant auth with team management, audit logs for compliance customers, observability (logs, errors, performance traces), backups that have been tested by being restored, and a status page. Most $30k MVP builds skip several of these — it's the gap between a build that survives 5 paying customers and one that survives 500.
Stripe for most Australian SaaS targeting Australian and US customers. Chargebee when you need flexible billing models, complex pricing, or revenue recognition for Series A+ stage. Paddle when you want it to be the merchant-of-record (handles GST/VAT/sales tax globally for you) — the per-transaction fee is higher but for cross-border SaaS the simplification can be worth it. We've integrated all three and can advise on the trade-offs for your specific customer base.
Default to Auth0, Clerk, or WorkOS for B2B SaaS — they handle the boring 80% (signup, login, MFA, SSO, magic links, SCIM) so we focus on your product. For B2C SaaS at lower price points, we sometimes use Supabase Auth or self-hosted (Lucia, NextAuth) to control costs. SSO/SAML support is increasingly required by mid-market customers — Auth0 and WorkOS make this trivial; rolling your own is months of work.
Discovery + clickable prototype: 2 weeks. MVP build: 12–20 weeks for most SaaS scopes. Plus typically 2–4 weeks beta with friendly customers before public launch. We deliver in 2-week sprints with running demos from sprint 2 onwards.
