SaaS Development

SaaS products you can actually charge for.

We build multi-tenant SaaS products for UK and US founders and product teams. Billing, authentication, permissions, dashboards, and analytics, built properly the first time so your first enterprise customer does not break the architecture.

Why teams call us

The hard parts of SaaS are not the features

Founders come to us after discovering that the boring infrastructure is what actually decides whether a product can be sold.

Billing was an afterthought

Plans, trials, upgrades, proration, failed payments, and refunds. Retrofitting real billing into a live product is far more painful than building it in.

One customer wants SSO and you cannot ship it

Enterprise deals die on security questionnaires. SSO, audit logs, and role permissions are not features you bolt on in a sprint.

Your MVP became the product

The shortcut that got you to launch is now the thing blocking every release. It happens to almost everyone, and it is fixable.

What we build

How we build SaaS

From a first version that validates demand to a platform that survives enterprise procurement.

01

MVP & Validation

Get something real in front of paying users quickly, without building a dead end.

An MVP that is not a throwaway

We build the smallest version that proves the value, on foundations you can keep. Speed now should not mean a rewrite in a year.

  • Core workflow only, built properly
  • Multi-tenancy from day one
  • Billing wired in before launch
  • Analytics to see what users actually do

Scope discipline

We will argue you out of features. The fastest way to launch is to build less, and we help decide what to cut.

Usage instrumentation

Product analytics wired in from launch, so pricing and roadmap decisions come from data rather than instinct.

Pricing and packaging support

Per-seat, usage-based, or tiered. We build the metering and limits to match, and make them changeable, because your first pricing model will be wrong.

02

Platform Foundations

The infrastructure that decides whether you can sell upmarket.

Multi-tenancy and permissions

Tenant isolation, organizations, teams, roles, and granular permissions designed at the data layer rather than patched into the UI.

Billing

Stripe subscriptions, metering, trials, proration, dunning, and invoicing that finance can reconcile.

Auth and SSO

Email, social, magic links, plus SAML and SCIM when enterprise buyers demand it.

Admin and support tooling

Internal tools so your support team can resolve issues without asking an engineer to run a query.

03

Scale & Enterprise Readiness

What you need before procurement will sign.

Audit logs and compliance

Activity trails, data retention, and the controls that SOC 2 and enterprise security reviews ask for.

Performance under load

Query tuning, caching, and background job architecture so growth does not degrade the experience.

Integrations and public API

A documented API, webhooks, and the integrations your customers ask for during sales calls.

Reliability

Monitoring, alerting, and incident response so downtime is measured in minutes.

Questions

SaaS development FAQs

The questions we get asked on almost every first call.

How much does it cost to build a SaaS product?

A SaaS MVP typically starts around [$45,000] because multi-tenancy, authentication, and billing are non-negotiable even in version one. Anyone quoting far less is usually skipping one of those, and you will pay for it later.

How long until we can charge customers?

Most MVPs take 12 to 16 weeks to reach paying users. We wire billing in before launch rather than after, so the day you go live you can take money.

Should we build an MVP or the full product?

An MVP, almost always. Not a flimsy prototype, but the smallest complete version that solves one problem well. You learn more from 20 paying users than from another six months of building.

Do you help with pricing and packaging?

We help with the technical side: metering, limits, plan logic, and making it all changeable. Your first pricing model will be wrong, so the important thing is that changing it is cheap.

What about SOC 2 and enterprise security reviews?

We build the technical controls that these reviews look for: audit logs, access control, encryption, and data retention. We are not auditors, but we make sure the engineering side is ready when you engage one.

Can you take over an existing SaaS product?

Yes. We audit the architecture, document it, and prioritize what is blocking you. Often the highest-value work is fixing the tenancy or billing model rather than adding features.

Do we own the code and infrastructure?

Completely. Your repositories, your cloud accounts, your intellectual property. We document everything and onboard your engineers whenever you are ready to bring it in house.
