Custom Software
Software built around your business, not a template.
R5 Systems builds custom software for businesses in South Africa and abroad — websites that embarrass the competition, internal tools your team actually uses, and web applications engineered to scale. Pretoria-based, remote worldwide.
What we build
- Premium marketing websites with real engineering underneath
- Customer-facing web applications and portals
- Internal business tools that replace fragile spreadsheets and manual workflows
- SaaS products, MVPs, and full production builds for funded startups
- Bespoke systems where off-the-shelf software doesn't fit
How we engineer
Modern stacks — React, TypeScript, Node, edge runtimes, Postgres — typed end-to-end and deployed on infrastructure that scales. We use AI tooling to move faster without cutting corners on architecture, testing, or maintainability. The work you can’t see is the work that makes the difference six months in.
Who it’s for
Founders building MVPs that need to be production-grade. Established businesses replacing outdated systems. Teams that have been burned by template shops, page-builder agencies, or contractors who disappear after launch.
Frequently asked
What kinds of custom software do you build?+
Marketing websites that need real engineering, web applications, customer portals, internal business tools, SaaS products, and bespoke systems where off-the-shelf software isn't a fit.
What tech stack do you use?+
Modern web stacks: React and TypeScript on the front-end, Node.js and edge runtimes on the back-end, Postgres for data, deployed on infrastructure that scales. The stack is driven by the problem, not by fashion.
Do you do custom software development in South Africa?+
Yes — we're based in Pretoria, South Africa, and work with South African clients across the country. We also serve international clients remotely.
How long does a typical custom software project take?+
It depends on scope. A focused website or internal tool can ship in weeks; full applications run months. After we see your brief we send back an honest timeline.
