What Is Included in a SaaS MVP Build?
A By Design UK MVP build delivers a production-ready platform — not a prototype — with the core functionality required to acquire and retain your first real users.
- Custom user authentication and role-based access control
- Scalable cloud infrastructure (AWS, GCP, or Azure)
- Admin dashboard and user-facing application UI
- Payment and subscription integration where required
- API architecture for third-party connections
- Security hardening and GDPR compliance considerations
- Handover documentation and developer knowledge transfer
Every line of code is written to support growth. You should never need to rebuild the foundation when your user base scales.
Why Do UK Startups Choose By Design UK for Their SaaS Build?
Founders choose By Design UK because they want accountability, not outsourced risk. We are a UK-registered development company based at Office 13, 25 Mollison Avenue, Enfield EN3 7LW — reachable on 020 3951 4908 during business hours.
Our track record includes Tackly.co.uk — a fully operational SaaS product serving 25 distinct industries. It is the kind of proof that offshore agencies cannot offer and that matters when you are committing serious budget to a build.
We also offer ongoing SaaS support plans from £797 per month, meaning we stay involved after launch to keep your platform stable, secure, and improving.
How Do You Know If You Are Ready for an MVP SaaS Build?
You are ready if you have a validated problem, a defined target user, and budget to build properly — because cutting corners on a SaaS foundation costs far more to fix later than it saves upfront.
If you are at the idea stage, our scoping process can help you prioritise the features that matter for launch and eliminate everything that can wait. An honest conversation now prevents expensive pivots six months into development.
