SaaS Platform Audit UK

Your SaaS platform is either compounding growth or quietly bleeding revenue — and without a thorough audit, you won't know which. By Design UK delivers independent, in-depth SaaS platform audits for UK businesses that need clarity on performance, security posture, scalability ceilings, and technical debt before they become costly problems.

What Is a SaaS Platform Audit and Why Does It Matter?

A SaaS platform audit is a structured technical review that exposes the gaps between where your platform is and where it needs to be. Over time, even well-built platforms accumulate inefficiencies — redundant API calls, bloated database queries, outdated dependencies, and UX friction that drives churn. Our audit process examines every layer: infrastructure, application code, third-party integrations, data pipelines, and user experience flows. The result is a prioritised action plan your team can act on immediately.

What Does Our SaaS Audit Process Include?

Our audit methodology covers six critical domains:

• Performance Analysis — Load time profiling, server response benchmarking, and database query optimisation opportunities
• Security Review — Authentication flows, data encryption standards, OWASP vulnerability checks, and GDPR compliance alignment
• Scalability Assessment — Infrastructure capacity, auto-scaling configuration, and multi-tenancy architecture review
• UX & Onboarding Audit — Friction mapping across key user journeys that affect activation and retention
• API & Integration Health — Endpoint reliability, rate limiting, versioning strategy, and third-party dependency risk
• Code Quality Review — Technical debt scoring, test coverage, and maintainability assessment

Who Carries Out Your SaaS Platform Audit?

By Design UK is a UK-registered digital development company based at Office 13, 25 Mollison Avenue, Enfield EN3 7LW. Our team has hands-on experience building and scaling SaaS platforms from concept to commercial deployment. A strong example of our work is Tackly.co.uk, a live SaaS platform we built that now serves 25 distinct industries across the UK. That build experience means we audit with the perspective of engineers who understand what good architecture actually looks like in production — not just in theory.

How Much Does a SaaS Audit Cost?

Audit scopes vary depending on your platform's complexity and the level of review required. For businesses that want continuous oversight, our SaaS monthly support plans start from £797 per month and can incorporate scheduled audit cycles, performance monitoring, and remediation support. For standalone audit engagements, pricing is scoped to your platform — speak to our team to receive a tailored proposal. We also build SaaS platforms from the ground up, with builds ranging from £18,000 to £650,000+, so we understand both ends of the complexity spectrum.
