The application, right in your browser
T10142CW is a Windows desktop application — but you can meet it here first. Below are three interactive replicas, captured from the real application at Build 1480 (the download is newer and keeps improving): click the menus, page through the certificate editor sections, and draw a signature on the touch pad. What you see here is exactly what the download gives you.
The menu bar, exactly as in the app — click the menus
Interactive replica of the T10142CW menu bar and status bar (captured at Build 1480; the download is newer) — the same menus in the same order with the same items, the same Yellow-on-Black test-instrument theme, the same green Certificate indicator, the same day-first date and 24-hour clock. Menus open exactly like the real app; clicking an item here only describes it — the download does the real work.
The Certificate of Compliance editor — click the sections and type
Interactive replica of the certificate editor (captured at Build 1480; the download is newer) — the same seven sections (General, Customer, Installation, Tests, Certifier, Contractor, Notes & Photos) and the same field labels as the real application. The fields accept typing. One honest difference — the app saves your certificate to your own computer; this browser replica keeps it only while the page is open.
The signature pad — draw your signature with the mouse or a finger
Interactive replica of the app's touch-screen signature pad (captured at Build 1480; the download is newer) — draw with a mouse, touchpad, pen or finger, exactly as on site. In the real app the signature is embedded into the certificate with the date, time and GPS (Global Positioning System) location, and Witness B observes Signer A — witnessing the witness. One honest difference — the app stores the signature in your document; this replica keeps it only while the page is open.

We are preparing screenshots of the actual application; they will rotate here.
No mock-ups, no stock images: what you will see is the application itself, exactly as you will use it.

Frequently asked questions
Which versions of Windows does T10142CW run on?
Windows 10 and Windows 11 desktop computers. T10142CW is a native Windows desktop application, not a browser app, so your work does not depend on an internet connection.
Does T10142CW need an internet connection?
No. Your certificates, customers, and documents live on your own computer and the application works fully offline. The optional BIESVA service can synchronise your data between your own computers when you do have a connection.
What happens after my 12 months of updates?
The application keeps working — it never stops. Your first licence includes 12 months of updates, and as an early adopter you can renew each following year at 50% off (R 6250) for as long as that offer runs. The renewal is optional: renew as required, for example after a major update or when you need the latest features.
Can I pay by Electronic Funds Transfer (EFT) instead of by card?
Yes. Email support@t10142.com and we will send you a pro-forma invoice. Your licence is delivered by email within one working day of your payment reflecting.
What if T10142CW does not work for me?
Every purchase carries a 30-day money-back guarantee. Email support@t10142.com within 30 days of your purchase and we will refund you in full.
How is T10142CW delivered?
Delivery is instant and digital: a personal download link is emailed to you the moment your payment clears, and the same link appears on the confirmation page. The link stays valid for 30 days.
Which languages does the application support?
The user interface supports all 11 official South African languages — this website already speaks them; choose yours from the language menu at the top of the page. Certificates and legal documents remain in English for audit and regulatory purposes.
How many people can use one licence?
One person per licence. If several electricians in your team will use T10142CW, each of them needs their own licence.
Built for South Africa
T10142 products are made in South Africa, for South Africa. This website already speaks all 11 official South African languages — choose yours from the language menu at the top of the page — and the application's user interface supports them too. Certificates and legal documents remain in English for audit and regulatory purposes, while the app itself speaks your language.
We understand South African electrical regulations — the South African National Standard (SANS) 10142, the Occupational Health and Safety Act, and the Electrical Installation Regulations (2009). The certificate templates are kept current with regulatory changes. The registered person who carries out or supervises the work remains responsible for testing, signing, and issuing every certificate — T10142CW prepares the paperwork so that responsibility takes minutes, not evenings.
