We engineer SaaS platforms that scale from 10 to 10,000 tenants without rewrites — multi-tenant isolation, Stripe billing with usage metering, RBAC, and a daily-shipping release pipeline. Auth, billing, audit logs and observability are designed in from day one, not bolted on later.
What is SaaS platform engineering? SaaS platform engineering is the architecture and build of multi-tenant software-as-a-service products, covering billing, tenancy, identity and observability. ClickTake delivers SaaS platform engineering services for UK and US founders, using Next.js, Postgres row-level security, Stripe Billing and AWS to ship platforms that scale from first user to millions.
Every engagement ships with these deliverables baked in — not bolted on later.
Row-level security or schema-per-tenant — chosen against your compliance needs, not by accident — with no cross-tenant data leaks.
Subscription, usage-based and hybrid billing models wired into Stripe with idempotent webhooks and proper proration.
Role definitions, resource-level permissions and org-scoped access — built so adding a new role doesn't require a migration.
Event ingestion, aggregation and rollups that feed Stripe — so customers see accurate usage in real time, not a monthly surprise.
Impersonation, feature flags, audit logs and admin actions — every privileged operation recorded and replayable.
Feature flags, trunk-based development and progressive rollouts — releases aren't a quarterly drama, they're a non-event.
