Build a SaaS Platform with Stripe — Engineered in the UK

Turning a software idea into a revenue-generating SaaS product requires more than code. It demands architecture decisions, payment logic, user management, and a team that has done it before. By Design UK builds production-ready SaaS platforms with full Stripe integration, serving founders and businesses across the United Kingdom.

What Does It Cost to Build a SaaS Platform with Stripe in the UK?

SaaS platform builds at By Design UK start from £18,000 and scale to £650,000+ for enterprise-grade products. The investment depends on your feature set, number of user roles, Stripe billing complexity — whether that's one-time charges, recurring subscriptions, usage-based billing, or connected accounts — and the integrations your platform requires. Every project begins with a scoping consultation so you receive a fixed, transparent quote before any work begins.

How Does Stripe Fit Into a SaaS Platform Build?

Stripe is the payment infrastructure of choice for serious SaaS products, and we integrate it at the core of your platform — not as an afterthought. We implement Stripe Billing for subscription management, Stripe Checkout and Payment Links for fast onboarding, webhook handling for real-time event processing, and Stripe Connect where your platform needs to facilitate payments between third parties. Every integration is built to Stripe's UK compliance standards, including Strong Customer Authentication (SCA) under PSD2.

What Stripe Features Do We Typically Build?

Depending on your product model, we commonly build: subscription tiers with free trials and proration, seat-based or usage-based billing, customer portal for self-service billing management, invoice automation, failed payment recovery flows, and multi-currency support. These are not templates — they are engineered specifically for your platform's logic.

What Is Included in a SaaS Platform Build?

A full build from By Design UK covers product architecture and database design, user authentication and role-based access, Stripe payment flows, admin dashboards, API development, and a responsive front end. For platforms requiring it, we also build multi-tenancy, team workspaces, and white-label capability. Post-launch, our SaaS monthly support plans from £797/month keep your platform maintained, monitored, and evolving.
