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.
