Double R Technologies is a Gauteng-based engineering studio. We build custom software, automation, and intelligent operational platforms for South African businesses — and we ship our own products under the OnlineHero banner along the way.
Most operational pain in a business doesn't come from a missing feature in a SaaS tool — it comes from the gap between the tools, the processes, and the people. The bit nobody sells software for. The bit everyone solves with a spreadsheet that breaks at month-end.
We build into that gap. Sometimes that's a small script, sometimes it's a whole platform. We don't mind which — we mind whether it works.
Our edge is the products we already run. InvoiceHERO and HRHero have been in production for years, processing real invoices for real businesses. When you commission a project, those battle-tested foundations come with — your build starts at 60%, not at zero.
And because we're local, accountable, and small, the person who picks up the phone is usually the person who wrote the code. That's not a slogan. It's just how we work.
Live, paying-customer products that double as the head-start for every project we take on.
A modern invoicing platform built specifically for the realities of South African business — VAT handling, EFT references, recurring jobs, chase emails that don't sound like a robot. Used standalone, or as the billing layer of a larger custom build.
Visit invoicehero.co.zaLightweight HR for teams that find Sage People too heavy and a spreadsheet too thin. Onboarding, leave, performance, payroll exports, mobile-first. Configurable for SA labour law and bargaining-council quirks.

What you can hold us to. If we breach one of these, you have grounds to walk.
Demos every week. Real software, not slides. If we can't show progress, we shouldn't be billing.
No jargon-bombing on calls or in invoices. If we wrote it, we can explain it to your accountant.
Every byte we write, you own. Repos handed over. No vendor lock. Stay with us by choice, not contract.
Local hours, local team. The number on the website is the number that rings on a real desk.
Boring fundamentals — tests, backups, monitoring, security. Not flashy demos with no plumbing behind them.
Small fix? We do that. Whole platform? We do that too. We won't oversize a project to inflate a quote.
The shape of most of our projects, with rough timing.
You call, email, or fill in the form. We reply same day with a 30-minute discovery call.
We hand back a plain-English spec and a fixed-price (or T&M) quote. You sign or you don't.
Weekly demos of working software. Adjustments baked in as we go — not deferred to phase 2.
Deploy, train, document. Optional retainer for ongoing changes & on-call.
