What Does SaaS Platform Development Actually Include?

A SaaS build at By Design UK covers every layer of your product — from discovery workshops and technical architecture through to UI design, backend development, cloud infrastructure, and a structured launch. We handle user authentication, subscription billing, role-based access, API integrations, and dashboards so you receive a platform that is ready for real users from day one, not a prototype that still needs months of work.

How Much Should You Budget for a UK SaaS Build?

Investment starts from £18,000 for a tightly scoped MVP and rises to £650,000 or more for platforms requiring multi-tenancy, complex automation, regulated data handling, or large-scale integrations. The right budget depends on the number of user roles, the complexity of your data model, third-party connections, and your target time to market. During a free scoping call we will give you an honest range before any commitment is made.

What Factors Influence the Final Cost of a SaaS Project?

Four variables drive cost more than any others: the number of distinct user types and permission levels, the volume of external API integrations, the reporting and analytics requirements, and whether the platform must comply with regulations such as GDPR, ISO 27001, or FCA guidelines. Being clear on these early keeps your budget accurate and your timeline realistic.

Can You Show Proof That You Have Built a Live SaaS Platform?

Tackly.co.uk is a live SaaS platform designed, built, and launched by By Design UK. It currently serves users across 25 industries and demonstrates our ability to deliver multi-functional, scalable software in a real commercial environment — not just in a demo environment. We encourage prospects to explore it before making any decision about working with us.

What Happens After Your SaaS Platform Goes Live?

Launch is the beginning, not the end. By Design UK offers SaaS monthly support plans from £797 per month, giving you a dedicated development resource for ongoing improvements, performance monitoring, security updates, and new feature releases. Clients on a support plan receive priority scheduling, which means faster turnaround when something needs attention or an opportunity arises to ship quickly.

Is Ongoing Support Really Necessary for a SaaS Product?

Yes. SaaS platforms require continuous iteration to remain competitive and technically secure. User feedback drives product decisions, infrastructure needs scale with growth, and third-party APIs change without warning. A monthly support plan ensures your platform never becomes stagnant or vulnerable between major development cycles.
