SaaS products built to be sold, supported and scaled.

A credible first release — multi-tenant, billed, self-onboarding, with one workflow done properly — is typically a five to low six-figure build. GTX Digital phases it so that the money is committed against a written scope at each stage, and so that a sellable product exists before the budget is exhausted.

Four to seven months is realistic for a product that one real customer can buy and use unaided, assuming the first phase answers who buys it and why. Design partners can usually be using it well before that, which is where the most valuable feedback comes from.

Multi-tenant, in almost every case. Separate instances feel safer and then quietly multiply your deployment, support and upgrade cost by the number of customers. The exceptions are genuine data-residency or regulatory requirements, and we design for those explicitly rather than by accident.

Often, and it is a strong starting point because the domain logic is already proven. The work is in retrofitting tenancy, extracting customer-specific assumptions, adding billing and onboarding, and deciding what deliberately will not be configurable. We assess feasibility honestly in discovery — sometimes a rewrite of the core is cheaper than the retrofit.

No, and you should not. Stripe Billing or an equivalent handles plans, proration, tax and dunning far better than a custom implementation, and the integration is a fraction of the cost. What we build is the mapping between your plans and your product’s entitlements, which is the part that genuinely is yours.

You do, completely. The repository, the cloud accounts, the Stripe account and the intellectual property are yours from the start. We are a development partner, not a co-founder, and nothing in the arrangement makes us difficult to replace.

We will help you reason about it but it is a commercial decision, not a technical one. What we build in is the instrumentation to answer it with evidence: usage per tenant and per feature, so you can see what people actually value rather than what they said in a sales call. Pricing changed on evidence beats pricing guessed once.

This is the decision that determines whether you have a product or an agency. The answer is usually a configuration option if several customers would use it, and a polite no if only one would. We build the configuration layer so that distinction is cheap to act on, but the discipline has to come from you.

Not day to day. The admin tooling is built so support and operations can do their jobs without engineering, and deployment is automated. You will eventually want technical capability in house or on retainer, because a product that is selling is a product that needs changing, but it is not a condition of launching.

For an early-stage product, typically hundreds rather than thousands of pounds a month in infrastructure, plus payment processing fees. We use managed services deliberately: at this stage every hour spent operating infrastructure is an hour not spent finding customers, and the cost difference is trivial next to that.
