SaaS Development .
Multi-tenant SaaS development in the UK. Architecture, data modelling, subscription billing, onboarding and dashboards, built to scale and maintained.
What's included
Everything you get.
Every SaaS engagement includes architecture, build, and a handover your internal team can maintain.
Product Architecture
Multi-tenant data model, API design, auth strategy (OAuth2, SAML, magic link): defined before the first commit.
Frontend (React / Next.js / Astro)
Dashboards, onboarding flows, settings pages. Fast, accessible, and built to your design system.
Backend & APIs
Node.js / Python / Go backends, PostgreSQL / Supabase data layer, REST or GraphQL APIs, webhook infrastructure.
Subscription Billing
Stripe integration. Plans, trials, metered usage, proration, customer portal, failed-payment recovery.
DevOps & CI/CD
Docker, Kubernetes or serverless (Cloudflare Workers), GitHub Actions, staging/production environments from day one.
Observability
Structured logging, error tracking (Sentry), uptime monitoring. So you know about issues before your users do.
Why clients come to us
Problems we fix.
The problem
Your MVP worked, but the architecture can't scale past 200 users
Our solution
We re-architect the data layer and APIs before growth breaks things. Not after.
The problem
You need multi-tenant isolation, but your codebase doesn't support it yet
Our solution
We design the right tenancy model for your product and migrate existing data safely.
The problem
Billing is a mess of one-off scripts and manual Stripe calls
Our solution
We implement a clean subscription engine. Trials, upgrades, proration, invoices. Done once, done right.
The problem
Feature requests keep piling up with no clear system for deciding what actually matters
Our solution
We help you build a lightweight roadmap process tied to usage data and customer signal, not whoever asked most recently.
How we work
A process you can follow.
Four stages. Each one has a clear output before the next starts.
- 01 Discovery
Map the product
We learn your users, your data model and what “done” looks like before any code is written.
- 02 Design
Architect the platform
Multi-tenant structure, auth, billing and core workflows — planned before build begins.
- 03 Build
Ship the SaaS
An experienced team builds it. Every pull request reviewed, every release tested.
- 04 Run
Scale it with you
Monitoring, support and iterations after launch — we don't disappear at go-live.
Common questions
Quick answers.
How long does a typical SaaS build take?
A focused MVP with billing, auth and a core feature set typically takes 10–14 weeks from discovery to production. Larger platforms with multiple integrations run 16–24 weeks.
Do you work with existing codebases?
Yes. We audit your current code first and give you an honest assessment. Refactor where it's worth it, rewrite where it isn't.
What happens after launch?
We offer ongoing maintenance plans covering security updates, dependency upgrades, monitoring, and feature sprints. We don't disappear post-launch.
Who owns the code?
You do, from day one. All IP is yours. We commit to your repository and hand over full access at every milestone.
Do you use AI/LLMs in the build?
Where it adds genuine value. AI-assisted features, vector search, document processing. Yes. We use OpenAI, Anthropic and open-source models depending on your requirements and data-privacy needs.
