Custom Software Built for Your Business
We design and build bespoke software for South African companies — online tools, internal systems, and the automation that runs them. Purpose-built, properly made, on a timeline agreed upfront.
“…they’re currently working on an automated stock management and invoicing system tailored specifically to our business.”
01 Overview
What is custom software?
Custom software is a tool designed, built and maintained around one business's specific needs — rather than forcing your operation to fit an off-the-shelf product. It's the right choice when the way you work is your competitive advantage, when existing tools don't quite fit, or when you're stitching together five subscriptions that should really be one system.
Clevex is a South African custom software development company. We build the online tools your customers use, the internal systems your team runs on, secure member areas, automation, and everything working quietly behind the scenes — for established businesses and funded startups.
We're deliberate about the projects we take on. When we commit to a build, you get a realistic timeline in writing and a system that's well-built and documented so your own team can work with it — not a black box you're locked into.
02 What we build
What we build
The kinds of systems we build, scoped to how your business works.
Bespoke Business Tools
Custom tools that match how your business actually works — quoting, scheduling, stock, secure client areas and internal dashboards built around your process.
Online Systems & Platforms
Fast, secure tools your customers or team log into every day — reliable, easy to use, and built to grow with you.
The Engine Behind It
The reliable systems working behind the scenes that store your information, keep it secure, and let everything talk to each other — designed to grow without falling over.
Connecting Your Tools
Link the tools you already use — your accounting, payments and other services — so information flows automatically instead of being re-typed by hand.
Keeping Your Data Organised
Well-organised information that stays clean, easy to find and safe as you grow.
Maintenance & Support
Updates and improvements after launch, quoted upfront — we don't disappear once the invoice is paid.

Questions, answered.
How much does custom software cost in South Africa?
It depends on scope, but most custom builds start in the tens of thousands of rand and scale with complexity. We give a clear, fixed scope estimate up front after a short discovery conversation — no vague open-ended hourly billing. See our pricing page for indicative ranges.
How long does a custom software project take?
A focused tool or first version can be ready in 4–8 weeks; larger systems run a few months. We break work into milestones so you see progress every couple of weeks rather than waiting in the dark.
Do you work with businesses anywhere in South Africa?
Yes. Most of the work happens over WhatsApp, calls and video, with in-person sessions where they help, so it doesn't matter where in South Africa you're based.
Will I own what you build?
Yes. You own the software and the rights to it. We hand over something documented and easy to maintain, so you're never locked in to us specifically.
Can you take over or fix existing software?
Often, yes. We can review your existing software, fix what's broken, and either maintain it or plan a clean rebuild — we'll tell you honestly which makes more sense.
Let's build it properly.
Tell us what you're trying to build or the problem you're trying to solve. We'll give you an honest assessment of scope, cost and timeline — and be direct if it's not a good fit.
