Do we own the software you build?

Yes, outright. The intellectual property, the source code and the infrastructure are yours from the first commit, and we will hand over everything needed to take it elsewhere. We would rather keep the work because you want us to.

How long before we have something we can sell?

For a focused first release, typically three to six months from kick-off to paying customers. That depends far more on how tightly the first version is scoped than on how fast anyone can type - the fastest projects are the ones that ship less.

Can you work with our existing developers?

Regularly. We will take the parts that need specialist experience - multi-tenancy, billing, infrastructure, security - and work alongside an in-house team on the domain logic they already understand better than we ever will.

What happens after launch?

Whatever you want to happen. Some customers take the platform in-house and keep us for the infrastructure; others keep the whole team on a monthly arrangement and treat us as their engineering department. Both are normal.

Who actually writes the code?

Crushed Ice, the bespoke software company in the same group, has been building business systems since 2003 and provides the engineering. Cube Systems owns the product thinking, the commercial shape and the relationship with you.

SaaS Development

Take a software product from idea to a live, multi-tenant, subscription platform - designed, built and run by one team.

Talk about your product All product development

Building software for one business and building software that a thousand businesses can subscribe to are different jobs. The second one has to handle tenants that never see each other’s data, customers who sign up at two in the morning, billing that reconciles itself, and a release process that does not require a maintenance window. Cube Systems builds SaaS products end to end - the commercial shape, the architecture, the application, the billing, the onboarding and the operational tooling that keeps it running once real customers depend on it. We have done it for our own platforms, which means the advice comes from having lived with the consequences rather than from a deck.

What it involves

Inside saas development

The parts of the job that decide whether a product can be sold at scale, rather than only delivered once.

Multi-tenancy done once, properly
Tenant isolation, per-tenant configuration and data residency decided at the architecture stage, where it is cheap - not retrofitted after your first enterprise customer asks about it.
Billing that reconciles itself
Plans, trials, proration, dunning, tax and upgrades wired to a payment provider and to your own reporting, so revenue is a number you can trust rather than a spreadsheet you maintain.
Self-serve signup and onboarding
A customer can find you, sign up, get value and start paying without anybody from your team being involved. That is the difference between a product and a project.
Security and auditability from day one
Role-based access, audit logging, encryption at rest and in transit, and the evidence trail that a procurement questionnaire will ask for eighteen months from now.
Product analytics built in
Activation, retention, feature usage and churn instrumented from the first release, so roadmap decisions come from behaviour rather than from whoever shouted loudest.
Deployment you are not afraid of
Automated builds, staged environments, migrations that run cleanly and rollbacks that work. Shipping on a Tuesday afternoon should be unremarkable.

In practice

Where this usually starts

Anonymised, but not invented. These are the situations people describe to us before anything gets built.

A consultancy with a method worth productising
The situation
A specialist consultancy had a spreadsheet-and-template process that clients paid handsomely for. It did not scale beyond the number of consultants they could hire, and the intellectual property walked out of the door every evening.
What changed
The method now runs as a subscription platform their clients use directly. The consultancy still sells expertise, but the recurring revenue no longer depends on billable hours, and the process is captured in software rather than in people.
A founder with a validated idea and no technical team
The situation
A founder had letters of intent from six prospective customers and a prototype held together with no-code tools that had already hit their limits. Hiring a team before there was revenue was not realistic.
What changed
A production platform was designed, built and launched by our team, with the founder owning the code and the roadmap throughout. The first paying cohort onboarded themselves, and hiring started once the revenue justified it.
An operator whose customers kept asking to buy the system
The situation
A business had built an internal system so good that competitors and suppliers kept asking whether they could use it. It was single-tenant, hard-coded to their own processes, and impossible to sell without a rewrite.
What changed
The system was re-architected as a multi-tenant product with configurable workflows, self-serve signup and subscription billing. It now runs as a separate revenue line alongside the original business.

How it happens

How a build actually runs

Five stages, each priced before it starts, and each one leaving you with something you own. You can stop at the end of any of them.

Shape
A few sessions working out what the product is, who pays for it and what the first version has to do. You leave with a written scope and a price, whether or not you go further.
Design
Screens, flows and the data model behind them, agreed before anybody writes production code. Changing a decision here costs an afternoon rather than a month.
Build
Two-week cycles with something working at the end of each one, in an environment you can log into. No six-month silence followed by a reveal.
Launch
Billing live, onboarding tested, monitoring in place, and the first real customers on the platform with somebody watching closely.
Run
Hosting, support and continued development for as long as you want it - or a clean handover to your own team, with everything documented.
