From SaaS idea to paying customers
We help founders and established businesses turn a product idea into a working subscription platform. We build the product and the unglamorous parts around it: billing, onboarding, permissions and admin.
The fastest way to find out whether a SaaS idea works is to put a focused version in front of paying customers. We help you decide what belongs in that first release and, just as importantly, what does not. A focused MVP is typically 8–12 weeks from signed-off requirements, and it is built on foundations that will not need throwing away once you grow.
SaaS products share a set of hard problems that are easy to underestimate: separating each customer's data safely, subscription plans and trials, invoicing and failed payments, team invitations and roles, usage limits, audit trails and a back-office for your own staff. We have patterns for all of these, so your budget goes on the features that make your product different.
After launch the work shifts to learning and iterating. We set up product analytics, error monitoring and a release process that lets you ship improvements safely and often. Your code, cloud accounts and Stripe account are in your name throughout, which matters when you come to raise investment or sell the business. Many clients keep us on after launch; others bring development in-house, and we make that handover straightforward with documentation and tests.

SaaS Product Development questions
How much should go into the MVP?
Only what a paying customer needs to get the core value. We work through your feature list with you and move everything else into a prioritised roadmap.
Can the MVP scale later?
Yes. We build on proven frameworks and a sound data model so growth means adding capacity and features, not rewriting the product.
Do you help with pricing and billing?
We implement whatever plans and billing rules you decide on, and can talk through common SaaS pricing structures, but the commercial decisions remain yours.
Will investors be able to review the code?
Yes. The code is in your repository, documented and tested, which makes technical due diligence straightforward.
How long does it take to build a SaaS MVP?
A tightly scoped MVP typically takes three to five months from signed-off requirements, depending on the core features, billing complexity and integrations. Cutting scope is usually the fastest way to shorten that.
How do you keep each customer's data separate?
We choose a tenancy model to suit your product, from shared databases with strict tenant scoping to separate databases per customer, and back it with automated tests that check data cannot leak between tenants.
Can we offer single sign-on to enterprise customers?
Yes. We can add SAML or OpenID Connect single sign-on and user provisioning, often as a feature of higher-tier plans, when your customers start asking for it.
Can the product support custom branding for each customer?
Yes. Per-tenant logos, colours, email templates and custom domains can be built in, and we plan for them early so they do not require rework later.
Which engagement model suits a SaaS product?
Many founders start with a fixed-scope MVP and then move to a dedicated team for ongoing development once the product has users. We set out the options and let you choose.
Can you help us move from a single-customer app to SaaS?
Yes. We review the existing code and data model, then plan the changes needed for multi-tenancy, subscriptions and self-service sign-up, usually in stages so current customers are not disrupted.
