What it is
SaaS development involves building multi-tenant web applications on a subscription model, requiring specialised architecture for tenant data isolation, subscription and usage-based billing, and instrumentation for customer success and product analytics.
What you get
Building a SaaS product requires decisions that most web application projects do not: how to isolate tenant data (schema-per-tenant, row-level security, or separate databases), how to meter usage for billing, how to handle plan limits without confusing users, and how to give customer success visibility into account health. These decisions are architectural and expensive to change later.
We implement multi-tenancy with Row Level Security in PostgreSQL or schema-per-tenant depending on isolation requirements and query patterns. Billing via Stripe Billing handles subscription creation, proration, usage-based metering, invoice generation, payment failure handling, and customer portal access. We configure the billing model to match your pricing structure, including seat-based, usage-based, and hybrid plans.
Product analytics and customer health instrumentation are standard, not optional. Mixpanel or PostHog for feature usage tracking, Stripe revenue metrics in a dashboard, customer health scores based on feature adoption and engagement, and automated churn risk alerts — because you cannot grow a SaaS business without understanding where users succeed and drop off.
Key capabilities
Each engagement is scoped to your requirements — these are the core capabilities we bring to the table.
Feature flags for plan-gated functionality
Onboarding flows with activation tracking
Product analytics with Mixpanel or PostHog
Admin dashboard with customer health and MRR metrics
Team and seat management with invitation flows
Our process
A structured, engineering-led approach that moves from understanding your goals to a production system — with no handoff surprises.
Typical engagement
8–16 WEEKS
We map your goals, constraints, and existing infrastructure. Scope is defined and success criteria agreed before any development begins.
We design the technical approach, select the right tools, and produce a milestone-driven delivery plan with no ambiguity.
Iterative development with regular demos. Code reviews, test coverage, and documentation happen in parallel — not at the end.
Production release with monitoring setup and handover documentation. We stay close during the first weeks post-launch.
Built with
Row-level security in a shared database is the right default for most B2B SaaS: simpler to operate, no per-tenant provisioning overhead, easier migrations. Schema-per-tenant is appropriate when enterprise customers require hard data isolation for compliance reasons. Separate database per tenant only makes sense at the very high end where tenant data volume or query patterns diverge significantly.
Stripe Billing handles proration automatically: upgrades are charged immediately for the remaining period at the higher rate, downgrades take effect at the next renewal. Feature access changes are handled by feature flags that update in real time when the subscription status changes. Edge cases like exceeding limits on a downgraded plan are scoped during product design.
We build with appropriate abstractions and avoid premature optimisation. The architecture accommodates growth without requiring a rewrite — but we do not over-engineer for 10,000 customers when you have 10. Database queries are indexed properly, N+1 queries are caught in review, and the most expensive operations are identified early. Scaling work is planned and executed as load warrants it.
