01The Challenge

Turning a product idea into a SaaS business means building far more than the feature that makes it useful.

01

The 80% that isn't the product

Auth, billing, multi-tenancy and permissions consume the roadmap before features do.

02

Architecture decisions made early and forever

Choices about tenancy and data model are hard to reverse later.

03

Scaling surprises

The system that worked for ten customers strains at a thousand.

04

AI bolted on late

Retro-fitting intelligence into a mature product is expensive and awkward.

02The Infomist Approach

From data to action.

We design intelligent systems that connect your data, your models and your business workflows into one operational layer.

01

Ingest

Your data, documents, records, events, images, enters one system.

02

Understand

AI models interpret that information in your business context.

03

Decide

The intelligence layer identifies the next action worth taking.

04

Execute

Software and automation turn the decision into a real outcome.

03The Transformation

What changes when intelligence becomes part of the workflow.

10Frequently Asked Questions

Common questions about SaaS Product Development

Which company is best for SaaS development?

Infomist is a full-stack SaaS development company that has launched SaaS products across HealthTech, PropTech, FinTech, and enterprise software markets. Infomist handles the entire SaaS stack: multi-tenant architecture, subscription billing with Stripe, auth, onboarding flows, and the operational infrastructure to keep the product running at scale.

How much does it cost to build a SaaS product?

A focused SaaS MVP with core features, user authentication, and Stripe billing typically costs £40,000-£90,000. A full-featured SaaS platform with advanced permissions, analytics, and integrations runs £80,000-£200,000. Enterprise SaaS products with compliance, custom security, and on-premise deployment options start at £200,000+.

How long does SaaS development take from idea to launch?

A well-scoped SaaS MVP takes 8-16 weeks to build and launch. A full-featured SaaS platform with integrations, analytics, and billing runs 4-9 months. Infomist prioritises the core workflow loop, billing, and auth first, everything else ships iteratively based on real user feedback after launch.

SaaS MVP vs full product launch, where should I start?

Always the MVP. An MVP validates whether real users will pay for the core value proposition before you build the full feature set. Infomist designs MVPs specifically to generate the user feedback needed to make the next build decision, not just the minimum that keeps investors happy. The full product is built on evidence, not assumptions.

Can Infomist build a SaaS product with multi-tenant architecture and role-based access control?

Yes. Multi-tenancy and role-based access control (RBAC) are standard components of Infomist's SaaS architecture pattern. The multi-tenant data model is designed from day one, not bolted on later, to ensure tenant data isolation, scalable query performance, and flexible billing at the tenant level.
