SaaS Development FAQs
Common questions about building a SaaS product with Synergi Tech
What types of SaaS products do you build?
We build all types of SaaS products — from B2B workflow tools, internal platforms, and industry-specific applications to B2C subscription services and marketplace platforms. Whether you have an idea to productise an existing process, launch a new software business, or create a platform to serve your industry, we have the product and engineering expertise to bring it to life.
How long does it take to build a SaaS platform from scratch?
Timelines depend on scope and complexity. A focused MVP — covering core features, authentication, and a billing flow — typically takes 8–12 weeks. A full-featured SaaS platform with admin portals, reporting, integrations, and onboarding flows usually takes 4–9 months. We work in agile sprints so you see working software throughout the build, not just at the end.
How much does it cost to build a SaaS product?
Investment varies based on the complexity, features, and technology choices involved. MVP projects typically start from £25,000–£50,000. Full platform builds range from £50,000 to £200,000+. We always begin with a scoping session to define requirements and provide a detailed, fixed-price proposal — so you know exactly what you're getting before any work begins.
Do you help with product strategy and go-to-market planning?
Yes — product strategy is a core part of what we do. Before writing a line of code, we work with you to validate your idea, define your target users, map out the feature set, and establish your pricing model. We also support go-to-market planning including user onboarding flows, trial and subscription setup, and early customer acquisition strategy. We want to help you build something that succeeds commercially, not just technically.
What is an MVP and do you offer MVP development?
An MVP (Minimum Viable Product) is a lean version of your SaaS platform that includes only the core features needed to validate your idea with real users. It lets you get to market quickly, gather feedback, and iterate — without the cost and risk of building everything upfront. MVP development is one of our most popular services, and we have a structured process that takes you from concept to a live, working product in as little as 8 weeks.
Can you build our SaaS product and then hand it over to our in-house team?
Absolutely. We build all platforms with clean, well-documented code using modern frameworks your team can easily work with. We provide full technical documentation, knowledge transfer sessions, and ongoing handover support to ensure your team can confidently take ownership. Many of our clients also choose to keep us as a retained development partner alongside their in-house team.
Do you have experience with subscription billing and multi-tenant architecture?
Yes — both are fundamental to SaaS and we have deep experience in both areas. We integrate Stripe, Paddle, and GoCardless for subscription billing, including free trials, plan upgrades, usage-based pricing, and dunning management. For multi-tenancy, we design architectures that securely isolate customer data while keeping operational costs efficient — whether using shared database, schema-per-tenant, or database-per-tenant approaches depending on your requirements.
What ongoing support do you provide after the platform launches?
We offer flexible ongoing support and development retainers after launch. This can include bug fixes and security updates, new feature development, infrastructure scaling as your user base grows, performance optimisation, and third-party integrations. Most clients retain us on a monthly basis to continue iterating on their product — we become a long-term extension of your team rather than a project-based supplier.
