Custom web systems
Bespoke web apps and dashboards built to run your operations — not just look good, but actually do the work.
Off-the-shelf tools get you 70 % of the way. The last 30 % is where your business actually lives — and it is where most teams end up back in spreadsheets and WhatsApp.
We design and build custom web systems that own that last 30 %. Operations dashboards, internal tools, client portals, full SaaS products. Built on a modern stack (Next.js, TypeScript, PostgreSQL) so they are fast, maintainable, and yours to keep.
Every build includes auth, role-based access, audit logs, and production monitoring from day one. We do not ship prototypes pretending to be products.
If any of this sounds familiar, we can help.
- Operations running on spreadsheets, WhatsApp, and memory
- Client reporting that has to be assembled by hand each month
- Internal tools that should exist but no one has built
- SaaS ideas stuck in Figma because engineering is too expensive
- Existing systems that cannot keep up with how the business actually works
Real deliverables, not strategy decks.
- Product scoping workshop and technical architecture
- Production-grade Next.js application with TypeScript
- Authentication, roles, and permissions built in
- PostgreSQL / Supabase backend with audit logs
- CI/CD pipeline, monitoring, and ongoing support plan
We pick the right tool for the job.

Frequently asked questions
How much does a custom web system cost?
Marketing sites start from R18,000 once-off. Operations dashboards and internal tools start from R45,000. Full SaaS products start from R85,000. All prices are starting points; complex scopes are quoted after a discovery call.
What tech stack do you build on?
Next.js, TypeScript, PostgreSQL, and Supabase — the same stack we use for LinxAI itself. We use Vercel for hosting and Stripe for payments where needed. Everything is open, standard, and easy for any competent developer to hand over to.
Who owns the code?
You do. We hand over the full codebase, Vercel deployment access, and all documentation at project close. There are no ongoing licence fees, platform lock-in, or "maintenance only we can do" clauses.
How long does a build take?
Marketing sites: 2–4 weeks. Operations dashboards: 4–8 weeks. SaaS products: 3–6 months. We scope exact timelines in the discovery call once we understand the full requirement.
What about POPIA compliance?
All custom web systems include a POPIA-compliant privacy policy, cookie consent mechanism, and data handling documentation as standard. We build the data flow and consent logic into the architecture from day one.
Do you provide ongoing support after launch?
Yes. Every build includes a handover period and optional ongoing support or retainer. We do not ship and disappear — our clients typically stay with us for years because we understand their systems.
