We design and build SaaS products for startups, scale-ups, and established businesses looking to productise their software from MVP builds and early-stage platforms to full-scale multi-tenant SaaS applications. Whether you're building a new SaaS product from scratch or evolving an existing internal tool into a commercial software product, we bring the technical architecture, UX design, and product thinking needed to build something that works, scales, and retains users.
At Stars Commerce we build SaaS products that are designed to grow not just to launch. Building a SaaS product is fundamentally different from building a website or a one-off application. It requires multi-tenant architecture, subscription billing, user authentication, role-based access, onboarding flows, and the scalable infrastructure to support a growing user base over time. We understand what makes SaaS products succeed technically and commercially and we build with both in mind from day one, so the decisions made early don't become costly limitations later.
From MVP builds and product validation through to full-scale SaaS platforms and ongoing product development we cover the full SaaS development lifecycle.
We build SaaS MVPs that validate your product idea with real users as quickly as possible — focusing on the core features that test the value proposition, built on a technical foundation that can scale when the product is proven.
We design and build full-scale SaaS platforms — multi-tenant architecture, subscription billing, user management, role-based access control, and the complete feature set your product needs to compete and grow in the market.
We integrate subscription billing and payment processing into your SaaS product — handling plans, pricing tiers, free trials, upgrades, downgrades, and payment failures — using platforms like Stripe to manage the complexity so you can focus on the product.
We design SaaS onboarding flows that activate new users quickly reducing time to value, minimising churn in the critical first days, and building the habits that turn trial users into long-term paying customers.
We build the APIs and integrations that connect your SaaS product to the tools and platforms your users already rely on CRM systems, payment gateways, communication tools, and data sources increasing product value and reducing friction for new users.
We work with existing SaaS products to improve performance, scalability, and user experience refactoring architecture that's struggling under load, optimising database queries, improving onboarding flows, and developing new features that drive retention and growth.
We build with modern, proven technologies chosen for performance, scalability, and long-term maintainability not just what's trending.
We start by understanding your product vision, target users, business model, and competitive landscape defining the core problem the product solves, the user journeys that matter most, and the technical requirements before any design or development begins.
We define the technical architecture multi-tenant structure, database design, API architecture, authentication system, billing integration, and infrastructure choosing the right stack and approach for your product's specific requirements and growth trajectory.
We design the user experience onboarding flows, core product workflows, dashboard design, and user management building an interactive prototype that lets you experience the product before development begins.
We build the MVP core features, authentication, billing, and onboarding in structured sprints with regular demos so you can see progress and provide feedback throughout the build rather than waiting until the end.
We test the product thoroughly functional testing, performance testing, security testing, billing edge cases, and multi-tenant isolation ensuring the product works reliably for every user before launch.
We manage the full launch process infrastructure setup, domain configuration, SSL, environment variables, and go-live checks ensuring a smooth, stable launch with everything verified before real users are onboarded.
After launch we continue developing new features based on user feedback, performance optimisation as the user base grows, and infrastructure scaling to support increasing demand treating your SaaS product as a living product that evolves continuously.
SaaS (Software as a Service) is software delivered over the internet on a subscription basis users access it through a browser without installing anything. What makes SaaS technically distinct from a regular web application is the multi-tenant architecture multiple customers sharing the same infrastructure while keeping their data completely separate combined with subscription billing, user management across organisations, and the scalability requirements that come with a growing paying user base.
A focused MVP with core features typically takes 3 to 5 months. A full-scale SaaS platform with advanced functionality, multiple integrations, and a complete billing and user management system takes longer usually 6 to 12 months depending on complexity. We recommend starting with an MVP to validate the product with real users before investing in the full build.
Multi-tenant architecture means multiple customers tenants share the same application and infrastructure, but each customer's data is completely isolated from every other customer. It's the standard approach for SaaS because it's significantly more cost-efficient to operate than running separate infrastructure for each customer. Getting the multi-tenant architecture right from the beginning is one of the most important technical decisions in SaaS development getting it wrong creates serious security risks and makes scaling much harder later.
Yes — subscription billing is a core part of most SaaS products we build. We integrate platforms like Stripe to handle subscription plans, pricing tiers, free trials, upgrades, downgrades, failed payments, and invoicing. Getting billing right is critical for SaaS — revenue leakage from billing failures and poor dunning management can significantly impact growth, which is why we treat it as a core product feature rather than a bolt-on.
SaaS development cost varies significantly based on product complexity, feature scope, integrations required, and whether you're starting with an MVP or building a full platform. It's one of the more substantial development investments but the recurring revenue model means the returns compound over time in a way one-off projects don't. After understanding your product vision and requirements, we provide a clear, detailed proposal based on exactly what needs to be built.
