What is SaaS?

Software your team or clients use through a browser. No installation. No licence fees.

SaaS stands for Software as a Service. Instead of buying and installing software on every computer, your users log in through a browser. You host it, you own it, and if you sell access to it your clients pay a monthly subscription.

The question to ask yourself is this: if you could start from scratch and design the perfect tool for how your business works — what would it do? That’s what we build.

What we build

Five types of project. One that probably sounds like yours.

01 · SaaS platform
“We have a product idea. We want to sell software subscriptions.”

Multi-tenant architecture, user management, Stripe billing, free trials, admin dashboards and a customer-facing portal. We’ve built our own and we know what the early mistakes look like. We help you avoid them.

Typical starting costFrom £12,000
02 · Internal web app
“Our team runs on spreadsheets and it’s costing us time every day.”

A tailored web application your team actually uses — job management, scheduling, reporting, approvals. Built around your exact process, not a generic tool you adapt yourself to.

Typical starting costFrom £3,500
03 · Client portal
“We want to give our clients a professional online space to interact with us.”

Branded client login portal with tickets, invoices, document signing, bookings and service requests. Reduces phone calls, looks professional and gives clients a reason to stay.

Typical starting costFrom £5,000
04 · Integrations & automation
“We use five different tools and none of them talk to each other.”

API development, webhook pipelines, automated workflows, scheduled jobs and middleware to connect your existing systems. We’ve integrated Microsoft 365, Xero, Stripe, GoCardless, Datto and custom REST APIs.

Typical starting costFrom £1,500
05 · App development
“We need an app our team or clients can install on their phone.”

We build progressive web apps (PWAs) that install to the home screen on iPhone and Android and behave like native apps — camera, GPS, push notifications, offline mode. For projects that need native device features beyond what PWA can offer, we scope and build React Native cross-platform apps that deploy to both iOS and Android from a single codebase.

PWA from£5,000 · Native from £20,000
Proof of concept

We built our own MSP platform. It works in production every day.

Rather than subscribe to someone else’s software, we built a complete management platform to run Thorne Technology. This is the best demonstration we can give you of what we build.

Straight answers

What we won’t do. And what we always will.

Code ownership

You own 100% of the code.

We push everything to a Git repository in your control from day one. You can take your codebase anywhere. We believe lock-in is bad for everyone.

Technology

We don’t use trendy frameworks.

We use proven, well-supported technology your business can maintain long-term. No framework of the month that’s abandoned in two years and leaves you stranded.

Scoping

Fixed-price quotes. No hourly billing surprises.

We scope every project in detail before we start, quote a fixed price, and hold to it. If we scope something incorrectly, that’s on us — not on you.

After launch

We don’t disappear at go-live.

Most SaaS products evolve after launch. We offer monthly development retainers, hosting, support and scaling as your user base grows. We stay.

How it works

FAQ

Common questions about SaaS and app development.

Have a question we haven’t covered? Ask us directly →

What is SaaS software?

SaaS stands for Software as a Service — cloud-based software your team or customers access through a browser with no installation. Users pay a monthly or annual subscription. Examples include CRMs, accounting software and project management tools.

How much does a SaaS platform cost to build?

A simple internal web app starts from around £3,500. A progressive web app starts from £5,000. A full multi-tenant SaaS platform with payments and customer portal typically ranges from £12,000 to £50,000+. We scope every project individually with a fixed-price quote upfront.

Do I own the code?

Yes — 100%. We push everything to a Git repository in your control from day one. You are never locked into using us for hosting or ongoing development. Most clients stay because continuity makes life easier, not because they have to.

Do you build mobile apps?

We build progressive web apps (PWAs) that work on iPhone and Android, install to the home screen and behave like native apps — from £5,000. For projects that need native device features, we build React Native cross-platform apps that deploy to both iOS and Android from a single codebase — from £20,000. Both approaches are significantly cheaper than building separate native iOS and Android apps.

What technology do you use?

PHP 8.3, MySQL, React and Vanilla JS on the frontend, Microsoft 365 and Graph API for identity and calendar, Stripe and GoCardless for payments, Brevo for email delivery, LiteSpeed for hosting. Proven, well-supported tools — no framework of the month that gets abandoned.

What happens after launch?

We offer ongoing hosting, support and development retainers. Most SaaS products evolve continuously — we work with you monthly to add features, fix bugs and scale the platform as your user base grows. We don’t disappear at go-live.
