SaaS Development Services
From first release to a product that scales
- We build and operate our own SaaS products
- Multi-tenancy, auth, roles and billing as standard
- Next.js, Node.js, PostgreSQL, Supabase, Stripe, AWS
A SaaS product is a journey, not a one-off project
Most SaaS failures are not code failures. They are the wrong first customer, a tenancy model that cannot scale, or billing bolted on too late. We plan the whole journey and build the stage you are at.
- 01
Strategy
Positioning, pricing model, tenancy model and the first customer segment.
- 02
Discovery
Workflows, data, integrations and the smallest product that can be sold.
- 03
MVP
Production-grade foundations with a narrow feature set.
- 04
Production
Onboarding, billing, permissions, integrations and support tooling.
- 05
Scale
Performance, cost, reliability and the second wave of features.
- 06
Modernise
Framework upgrades, architecture changes and platform moves.
SaaS product strategy and discovery
Before design or code, we answer the questions that shape everything downstream. Discovery is short and produces decisions, not a slide deck.
Who the first customers are
How the product makes money
How tenants are modelled
What to build versus integrate
From a sellable MVP to a product customers rely on
An MVP that is thrown away is expensive. Ours is built on the same foundations as the production product: real auth, real billing, real tenancy, with the feature set deliberately narrow.
Ship the narrow version
Learn from paying users
Widen without rewriting
The SaaS capabilities we build as standard
Every SaaS product needs most of these. They are designed together, because permissions, plans and tenancy interact in ways that are painful to fix later.
Multi-tenancy
Authentication and SSO
Roles and permissions
Subscriptions and billing
Integrations and public APIs
Dashboards and analytics
Onboarding and self-serve
Background jobs and notifications
Audit, security and compliance
Cloud deployment, scalability and security
A SaaS product is judged on uptime and trust as much as on features. We set up the operational side so it is boring, which is what you want.

SaaS products SyncScrum designs, builds and runs
Two products our own team ships and operates, built with the same stack and the same decisions described on this page.
One digital identity across a website, a BioCard and an email signature
Blyn combines a BioCard digital business card, an email signature builder and a website builder that starts from a Google Business Profile listing. Under the hood it is a multi-product SaaS: an authenticated dashboard, handle-based public pages resolved at the edge, generated customer websites on subdomains and verified custom domains, Google data import with automatic sync, lead capture, analytics, asset storage and Stripe billing with plan-gated features.
- Next.js
- Supabase auth
- Stripe billing
- Custom domains
- Edge routing
- Google data sync
Design intelligence extracted from any live website
Lunor is a Chrome extension, also available for Brave, Edge and Arc, that inspects a live page and turns it into usable design tokens: spacing, radius and type scales, colour palettes with usage counts, WCAG contrast issues, media and SVG export, Tailwind config export and full-page capture. It runs local-first, with no backend dependency for core scanning.
- Chrome Web Store
- Local-first
- Tailwind export
- Contrast checks
- Full-page capture
Modernising an existing SaaS product
If you already have a product, the work is different: protect revenue while replacing what holds it back. We begin with a technical review and a prioritised plan.
- Framework and dependency upgrades, including moves to Next.js and React from older stacks
- Single-tenant to multi-tenant re-architecture with safe data migration
- Replacing home-grown billing with Stripe, including plan and proration logic
- Adding SSO, audit logs and the controls enterprise buyers ask for
- Performance, database and cloud cost work with measurable targets
- CI/CD, monitoring and on-call hygiene so releases stop being events

SaaS development questions, answered
What founders and product leaders ask before starting a SaaS build.
What does a SaaS development company actually do?
A SaaS development company designs, builds and usually helps operate a software product that customers subscribe to. That covers product strategy and discovery, UI/UX, the application itself, the multi-tenant architecture underneath it, authentication, roles and permissions, subscription billing, integrations, cloud deployment and the ongoing releases after launch. SyncScrum covers all of those stages and also builds and runs its own SaaS products.
How is SaaS development different from ordinary web app development?
A SaaS product serves many customers from one codebase, so tenancy, data isolation, self-serve onboarding, subscription billing, plan-based feature gating, usage limits and operational monitoring are built in from the start. A single-customer web application can skip most of that. Getting those foundations right early is what keeps a SaaS product cheap to scale later.
Should we start with an MVP or build the full product?
Almost always an MVP, but a real one: production-grade code, real authentication and billing, a narrow feature set. That lets you sell and learn early while keeping the architecture ready for the full product. Our MVP development service is designed for exactly that first release, and this page covers what happens after it.
What is multi-tenancy and which approach do you use?
Multi-tenancy means one deployment serves many customer organisations while keeping their data separate. The common options are a shared database with tenant-scoped rows, a schema per tenant, or a database per tenant. We choose based on your isolation requirements, compliance needs, expected scale and budget, and we explain the trade-offs before committing.
Do you build subscription billing from scratch?
No. We integrate a billing provider, most often Stripe, and build the product-side logic around it: plans, trials, upgrades and downgrades, feature gating, invoices and payment history. That is the same approach we use in Blyn, our own SaaS product.
Can you take over or modernise an existing SaaS product?
Yes. SaaS modernisation work includes upgrading frameworks, moving single-tenant code to multi-tenant, replacing home-grown billing with Stripe, adding SSO, improving performance and cost, and setting up proper CI/CD and monitoring. We start with a technical review so you know the state of the codebase before deciding on scope.
Which technologies do you use for SaaS products?
Typically Next.js and React on the frontend, Node.js or Python services, PostgreSQL, Supabase or Firebase for auth and data where they fit, Redis for caching and queues, Stripe for billing, and AWS, Google Cloud or Azure for hosting with Docker and Kubernetes or managed platforms. We pick the stack for the product, not the other way round.
What happens after launch?
SaaS products are never finished. Most clients keep a dedicated team or a smaller retained team for releases, customer-driven features, integrations and operations. That can run as a managed engagement or as staff augmentation inside your own team.
Where SaaS development connects
Start with the MVP, add AI where it earns its place, or build a single-organisation platform instead.
The focused first release of your SaaS product: production-grade foundations with a narrow feature set you can sell and learn from.
LLM features, AI agents and automation built into SaaS products, from assistants inside the app to document intelligence.
For platforms that serve one organisation rather than many subscribers: internal tools, portals, workflow systems and integrations.
Tell us about the product. We will tell you what the first release should be.
A discovery conversation costs nothing and usually clarifies the tenancy model, the pricing model and the smallest version worth building.
