SaaS Development

Most SaaS products do not fail because the core feature was wrong. They fail because the things around the core feature — billing, tenancy, permissions, onboarding, support tooling — were treated as details to handle later, and “later” arrived at the same time as the first hundred paying customers. We build SaaS platforms with that infrastructure designed in from the start, so growth is a commercial problem rather than an engineering emergency.

What this covers

Multi-tenant SaaS platforms built to onboard, bill and retain customers without re-architecture at every stage of growth.

• Multi-tenant architecture and data isolation
• Subscription billing, plans and metering
• Authentication, roles and granular permissions
• Self-serve onboarding and trial flows
• Admin and customer support tooling
• Usage analytics and product telemetry
• API design and third-party integrations

Where SaaS builds usually go wrong

Four failure modes account for most of the rescue work we are asked to do.

Tenancy decided too late. Retrofitting tenant isolation onto a single-tenant schema is one of the most expensive migrations in software. It is a decision to make in week one, not month nine.

Billing bolted on. Plans, proration, upgrades, downgrades, failed payments and refunds are business logic, not a payment provider integration. Treating them as the latter produces revenue leakage nobody notices for two quarters.

No admin tooling. If your support team cannot impersonate a user, adjust a subscription or diagnose a failed webhook without an engineer, your engineers become the support team.

Permissions as an afterthought. Enterprise buyers ask about roles, audit logs and SSO during procurement. Adding them under deal pressure is how deadlines get missed.

How we build it

A typical engagement runs in four stages, with something usable at the end of each.

1. Discovery and architecture. We map your pricing model, tenancy requirements and integration surface, then produce an architecture and a delivery plan with costs attached.
2. Foundation. Tenancy, authentication, billing and deployment pipeline go in first. Unglamorous, and it is what everything else depends on.
3. Product build. Features ship incrementally behind flags, with staging environments your team can review against real data.
4. Launch and iterate. Monitoring, alerting and support tooling go live with the product. We stay through the settling period rather than handing over at the peak of instability.

Technologies we work with

We select the stack against your requirements and your team’s ability to maintain it, not against fashion.

• Backend: Node.js, Python, Go, PHP
• Frontend: React, Next.js, Vue
• Data: PostgreSQL, MongoDB, Redis
• Billing: Stripe, Paddle, Chargebee
• Infrastructure: AWS, GCP, Docker, Kubernetes, CI/CD

What you get

• A production platform with documented architecture
• Source code and infrastructure you own outright
• Deployment pipeline and environment configuration
• Admin tooling your support team can actually operate
• Handover documentation and a working knowledge transfer

Frequently asked questions

How long does a SaaS build take?

A focused first release typically runs three to five months. The variable is rarely the feature set — it is the number of external systems that need integrating and how settled your pricing model is.

Can you work on an existing platform?

Yes. A significant share of our work is taking over products built by someone else, whether to add capability, fix scaling problems or make an enterprise-readiness push. We start with an architecture review so you get an honest assessment before committing to a plan.

Who owns the code?

You do, in full, from the first commit. Repositories are yours and we work in them directly.

What happens after launch?

Most clients continue with an ongoing arrangement covering maintenance, monitoring and further development. Some take the product fully in-house, which we plan for and support with proper handover.

How we start

Every engagement starts with a short, fixed-scope conversation. You leave with a plan and a price whether or not you continue with us.
