Custom Web App Build: Portals, Internal Tools & SaaS Replacement - Gold Coast Ecommerce

Build Custom App Build

The app your business actually needs. Without the six-figure quote.

Portals, internal tools, dashboards, and the spreadsheet that quietly became your business. We scope it with an interview, prototype in days and ship in weeks. Agents write the first draft of every feature. Senior engineers review every line. You own the code.

01 · What you get

What you get

Everything below is in writing before we start. If it's not on the list, it's not in the price, and we'll tell you before that becomes a problem.

  • A requirements document and a clickable prototype, before you commit to the build
  • A fixed-price, fixed-scope build on TypeScript, Postgres, and Cloudflare or Docker with Coolify. The same stack runs our own agency.
  • Logins, roles, audit logs, and connections to what you already use: Xero, ClickUp, Shopify, Magento, HubSpot, anything with an API
  • Automated tests, a staging environment and a deploy pipeline
  • Documentation and a handover session. A care plan if you want us to keep running it.
  • You own the repository and the infrastructure accounts. All of it.

02 · How it runs

Agents do the first draft. We check every line.

The interview turns “we need a portal” into a list of 60 to 200 items you can read and argue with before we price anything. Then we build in weekly releases to a staging site, so you're clicking around working software from week one. Every AI-written change is reviewed and tested before it goes in.

The whole process, in five steps

05 · Questions

Questions we get asked

Straight answers. If yours isn't here, ask us. We reply within one business day.

After launch

We don't disappear after launch.

Every build has a care plan to move onto, from $39/month + GST: a monthly report, a named person to call, same-day replies, and no lock-in.

Hosting & care plans
Why is it cheaper than an agency quote from two years ago?

Because agents now draft the predictable 60 to 70% of a build (auth, CRUD, integrations, scaffolding) in hours. Senior time goes on judgement, review and testing. That's the part you're paying for.

Will it be maintainable?

Yes. It comes with tests, documentation and a conventional stack. Any competent team can pick it up. So can you, if you want to keep building with AI tools yourself.

Can you replace our SaaS stack?

Usually. We map what each tool does, keep the ones that earn their keep, and replace the rest with one app built around how you work.
