What Makes SaaS Different
A bespoke internal system has a known number of users who can be trained. A SaaS product has strangers who sign up at three in the morning, expect to understand it without help, share nothing with each other, and cancel instantly if it breaks.
That changes the engineering priorities. Tenant isolation must be structural rather than a filter someone might forget. Onboarding is a product feature, not documentation. Billing has to handle upgrades, downgrades, failed cards, refunds and tax. And observability matters more than in almost any other kind of software, because your customers will notice an outage before you do unless you build for it.
What We Build
- Multi-tenant architecture with strict data isolation
- Authentication, roles, teams and single sign-on
- Subscription billing, trials, plans, usage metering and invoicing
- Self-serve onboarding and in-product guidance
- Admin console for your own support team
- Product analytics and event tracking
- Public API and webhooks for your customers’ integrations
- Cloud infrastructure, CI and CD, monitoring and alerting
- Backup, disaster recovery and data-export tooling
- Security review and compliance groundwork
MVP First, Deliberately
The most expensive mistake in SaaS is building for twelve months against assumptions nobody tested. We aim to get a genuinely usable version in front of paying or trialling users in three to four months, covering one workflow end to end rather than five workflows partially.
That version is not a throwaway prototype. It has real architecture, tests, analytics and billing, because the point is to learn from real usage and keep building on the same foundation. What we defer is scope, not quality.
Building So It Can Scale Later
Premature optimisation wastes money, but some decisions are expensive to reverse: how tenants are separated, how the data model handles a customer with a hundred times more records than average, whether long jobs block a request, and whether you can deploy without downtime.
We make those decisions consciously at the start and keep everything else simple. The result is a product that runs cheaply at ten customers and does not need rewriting at a thousand — which is the point at which a rewrite is least affordable.
Running It After Launch
Shipping is the start. We set up monitoring, error tracking, uptime alerting, performance dashboards and structured logs so problems are visible early, plus release processes that let you deploy several times a week without fear.
From there we can continue as your product team on a monthly basis, work alongside engineers you hire, or hand over completely with documentation and a transition period. You own the code, the infrastructure and the accounts throughout.
