SaaS development
services.
Magora is a UK SaaS development company — a senior SaaS development agency based in Shoreditch, London. We design and build software-as-a-service products end to end — product strategy, multi-tenant architecture, subscription billing, integrations, AI features and the operations that keep them running — for startups, SMEs and enterprises.
SaaS product strategy & discovery
Who pays, for what, and how the product grows from ten customers to ten thousand. Pricing model, tenancy model, compliance scope and a costed roadmap before a line of production code.
Custom SaaS application development
Web app, admin console, customer portal and mobile companion apps where you need them — one codebase your team can own, in React, Vue, Laravel, Node.js or Python.
Multi-tenant platform engineering
Shared schema, schema-per-tenant or database-per-tenant, chosen for your customers rather than by habit. Tenant isolation is tested, not assumed, and enterprise customers can get their own region.
Subscription billing & monetisation
Plans, trials, seats, usage-based metering, proration, dunning and UK VAT — built on Stripe Billing and wired to entitlements, so a downgrade actually switches features off.
APIs, SSO & integrations
A public API your customers can build on, SSO via SAML and OIDC for enterprise buyers, and the integrations that close deals — CRM, accounting, payments, Slack and Microsoft 365.
AI SaaS features
Copilots, retrieval over your customers' own data, document extraction and agents that act inside the product — with per-tenant data boundaries and cost limits. See our AI and ML development work.
Three routes
into SaaS.
The same senior SaaS developers from kickoff to handover. Weekly demos. No offshore rotation.
Launching a new SaaS product
A production-grade SaaS MVP in 6–8 weeks, from £10,000: sign-up, billing, the one workflow customers pay for, and the foundations to grow without a rewrite.
Turning expertise into a product
An internal tool, a spreadsheet the whole sector copies, a service you deliver by hand — rebuilt as subscription software other businesses can buy.
Moving software to SaaS
On-premise or single-customer systems re-platformed for many tenants — SSO, audit logs, data residency and a migration that keeps existing customers running.
What SaaS development
costs in the UK.
Our 2026 pricing in GBP. Every engagement starts with a free working prototype and an NDA on day one; source code and IP transfer to you on payment. Final price depends on scope, integrations and compliance — see our UK software development pricing or try the cost calculator.
Free working prototype — a clickable version of your core SaaS workflow before any paid engagement.
Two weeks with a senior Product Owner and Solution Architect: scope, tenancy and billing model, architecture, estimate and roadmap.
A production-grade MVP for funded startups, typically 6–8 weeks: accounts, billing and the workflow your first customers pay for.
A complete multi-tenant web and mobile platform, admin console and integrations, built by our senior in-house team.
Multi-role, audit-logged, integration-heavy platforms with SSO, data residency and regulated-sector compliance.
Maintenance retainer: hosting and monitoring, SLAs, security updates and a steady roadmap of new features.
Six steps from idea
to paying customers.
Weekly demos on a staging environment you can log in to, so progress is something you use rather than something you are told about.
Free working prototype
Before you commitA clickable version of the core workflow, tested with real prospective users. It settles the "is this the right product" question before anyone is paid to build it.
Discovery sprint
2 weeksPricing and packaging, tenancy model, integration list, compliance scope and a costed roadmap. You leave with a document you can take to investors — or to another supplier.
Architecture & UX
Within discoveryData model, tenant isolation, identity, billing and deployment decided up front, alongside the onboarding and account screens that decide whether a trial converts.
MVP build
6 – 8 weeksTwo-week sprints with a working release at the end of each. Sign-up, billing and the paid workflow first; everything else earns its place in the backlog.
Launch & first customers
Go-liveProduction hosting, monitoring, backups and product analytics in place before the first invoice goes out — so you can see where trials drop off from day one.
Scale & iterate
OngoingEnterprise features as the customers who need them arrive — SSO, audit logs, custom roles, data residency — plus performance work as tenants and data grow.

What clients
say.
Verified reviews from our Clutch profile — 75+ verified client reviews.
“They're accessible, and it doesn't feel like I'm working with a faceless team.”
“Broader than just the code itself, the team strived to understand the entire project.”
“We were very happy with the overall experience.”
Platforms
we've shipped.
Four platforms that many organisations or users log in to, from call-centre AI to online learning, a sports marketplace and clinical research. Each card gives the problem, what we built and how it is used.
Empath AI
- Problem
- Call-centre agents had no way to pick up undeclared signs of caller vulnerability, such as anxiety or cognitive decline, during a live call.
- Built
- A SaaS platform that analyses vocal biomarkers in live calls, turns them into guidance prompts shown to the agent inside Microsoft Teams, and adds call management reporting and anonymous diagnosis reporting.
- Outcome
- Agents get live, empathetic guidance in the tool they already use, and managers see caller and agent-wellbeing trends without exposing individuals.
Eurekly
- Problem
- Quality one-to-one online learning was hard to plan, book and pay for in one place.
- Built
- A web learning platform where students plan, book and take lessons with experienced professionals and connect with other students, with video conferencing and a payment gateway built in.
- Outcome
- Learners study online with expert instructors and a community of other students, with scheduling, video and payment handled in one product.
GAIN
- Problem
- Finding a sports academy, gym or coach meant switching between several apps that each showed little detail.
- Built
- An app that puts academies, gyms and coaches in one directory with detailed profiles, booking and scheduling, and reviews and ratings.
- Outcome
- Trainees find and book in one place, and academies gain visibility and can manage their reputation through reviews.
Anova
- Problem
- There was no single platform where sponsors and research organisations could find each other, so matching sites and participants was slow and costly.
- Built
- A web platform, Anova OneSource, that coordinates the clinical-trial process between doctors, research organisations and sponsors through standardisation and automation.
- Outcome
- The first version matches research organisations with sponsors, and we keep adding functionality for biopharma companies, physicians and patients.

SaaS development
questions.
SaaS (software as a service) development is building software that customers use in the browser or an app and pay for by subscription, instead of installing it themselves. Besides the product itself, it means building the parts a single-customer system never needs: multi-tenancy (many customers on one platform, with their data kept apart), subscription billing, self-service sign-up, user roles, and hosting that the vendor runs for everyone.
At Magora a SaaS MVP starts from £10,000, a full multi-tenant SaaS platform £25,000–£60,000, and enterprise SaaS with SSO, audit logs and regulated-sector compliance from £80,000 (2026 prices, GBP). A two-week discovery sprint is from £3,000, and the first step — a working prototype — is free. Running and developing the product after launch is typically from £1,000 a month.
The biggest price drivers are the number of integrations, the billing model and compliance (GDPR, FCA, NHS DSPT) rather than the number of screens.
A production-grade SaaS MVP typically takes 6–8 weeks after a two-week discovery sprint. A full platform with admin tooling, integrations and mobile apps takes longer and is planned in phases, so paying customers arrive before the whole roadmap is finished.
Most SaaS products should be multi-tenant: one codebase and one deployment serving every customer, which keeps hosting and maintenance costs flat as you grow. The real decision is how data is separated — a shared schema with row-level isolation, a schema per tenant, or a database per tenant. Customers in regulated sectors sometimes need their own database or region, so we design for that option early even when it is not built on day one.
Yes. We re-platform on-premise and single-customer systems into multi-tenant SaaS — adding tenant isolation, sign-up, billing and SSO, and migrating existing customers without a big-bang cut-over. Where the old code cannot carry the load, we replace it module by module, as described in our enterprise application development work.
Yes. We build AI SaaS features on large language models from OpenAI, Anthropic and Google — assistants, search over a customer's own documents (RAG), data extraction and agents — with each tenant's data kept separate, usage capped per plan so AI costs cannot outrun revenue, and evaluation tests so quality does not drift between model versions.
You do. We sign an NDA on day one, the code lives in your repository as it is written, and source code, designs and IP transfer to you on payment — which matters when investors run due diligence on your SaaS business.
Tenant isolation is covered by automated tests, personal data is encrypted in transit and at rest, and hosting can be kept in the UK or EU. Roles, audit logs and data-export and deletion tools are built in, so answering a customer's security questionnaire or a subject access request does not become a project of its own.
Ask to see SaaS products the team has shipped and still runs, how they keep each customer's data apart, how billing and sign-up are handled, and who supports the platform after launch. Published prices and a working prototype before any paid work make the choice easier: at Magora both come first. See our case studies and London software house.
Usually Laravel, Node.js or Python on the back end, React for the web app, and React Native or Flutter when the product needs mobile apps, with hosting in the UK or EU. We choose the stack per product and explain the choice in writing during Discovery, and you own the code.
Hosting depends on usage and is billed at cost. Development after launch is either a maintenance retainer from £1,000 a month (support, SLAs, security updates and new features) or a dedicated team that keeps building the roadmap.
