In short

SaaS development is building a subscription software product that many customers use from the cloud. LOLCorp designs and builds multi-tenant SaaS platforms with billing, roles, analytics and scalable infrastructure, from first MVP through growth. We also run our own SaaS products, such as GoFloe and PushCo.

01 Validate

Define the smallest release that proves demand and earns its first paying customers.

Tenant isolation, role-based access and SSO-ready auth that will survive an enterprise security review.

02 Architect

Pick a stack and data model that scales commercially as well as technically.

Subscriptions, usage metering, invoices and dunning through Stripe or your provider of choice.

03 Build

Ship the MVP in focused sprints with analytics wired in from the first release.

Start lean, then grow on infrastructure that scales horizontally without a rewrite.

04 Grow

Iterate on real usage data with a retainer or hand to your in-house team.

Clean architecture, documentation and metrics dashboards that stand up to due diligence.

FAQ

SaaS Development: common questions

How much does it cost to build a SaaS product?

It depends on scope: features, tenants, billing complexity and scale. A focused MVP costs far less than a full platform. The instant quote tool gives you an indicative range in under a minute.

Can you take over an existing SaaS codebase?

Yes. We start with a code and infrastructure audit, then stabilise, document and extend it.

Which technologies do you use?

Typically TypeScript, React, Node, Python and PostgreSQL on AWS, GCP or Azure, chosen to fit your team and roadmap.
