Questions Belfast businesses ask us

Straight answers, real numbers. Anything else — ask on a 30-minute call and you'll have a written proposal within five working days.

How much does a SaaS platform cost to build?

A first version with logins, subscription billing and an admin panel typically runs from £25,000 to £60,000 over 10 to 14 weeks. We scope the smallest launchable version first, which keeps the upfront number down.

What stack do you build on?

Next.js with TypeScript, Supabase Postgres with row-level security, and Stripe for billing. The marketing site, the product and the admin panel ship as one system, so there's a single codebase to run and extend.

Can you work with a Belfast business remotely?

Yes — we're remote-first with clients across Northern Ireland and the UK. Weekly demos on a private preview URL mean you see the real product every week, not a slide deck.

Who owns the platform?

You do — code, data and accounts are all registered to your business. There's no lock-in and nothing to buy back if you ever move on.

Who runs it after launch?

Either your team, or us on a monthly retainer: hosting, uptime and error monitoring, security patching, daily backups and a feature increment each month, from £20 to £500 a month depending on usage.
