Frequently Asked Questions: SaaS Development for UK Businesses

What is the typical timeline to build a SaaS MVP in the UK?

A dedicated SaaS Minimum Viable Product typically takes between 4 to 8 weeks to develop and launch. More complex enterprise platforms with custom integrations typically take 8 to 14 weeks. We work in rapid 2-week sprints so you can see live working progress every fortnight.

How do you ensure data isolation in a multi-tenant SaaS application?

We implement tenant isolation at the database layer using either separate tenant schemas, row-level security policies, or siloed tenant databases depending on your compliance requirements. All data is encrypted at rest using AES-256 and in transit via TLS 1.3.

Which technology stack and cloud infrastructure do you recommend?

For modern SaaS platforms, we typically recommend React or Next.js for high-performance frontend web apps, Node.js or Python for backend microservices, and AWS (Lambda, ECS, Aurora Serverless, CloudFront) for high-availability cloud infrastructure.

How does subscription billing and UK VAT compliance work?

We integrate enterprise billing engines like Stripe Billing and Chargebee. This handles recurring subscriptions, free trials, tiered usage pricing, automated pro-rata invoicing, and automatic UK and European VAT calculation and receipt generation.

Do we retain 100% ownership of the source code and intellectual property?

Yes. 100% of all intellectual property, source repositories, cloud infrastructure scripts, and database assets belong entirely to your company upon project completion.

How much does a custom SaaS development project cost in the UK?

A focused SaaS MVP typically starts from £5,000 to £15,000 depending on feature scope and third-party integrations. Full enterprise SaaS platforms range from £15,000 to £35,000+. Contact us for a free technical scoping call and transparent fixed-price proposal.
