E-Signature for South African Construction & Engineering
Get construction contracts, subcontractor agreements, and site safety declarations signed on the job — from any phone. ECT Act compliant.
How Construction use SignZA
Construction and engineering companies sign high volumes of contracts, subcontractor agreements, variation orders, and safety compliance documents throughout every project. On a large site, getting a subcontractor to physically sign a document can take days — the right person isn't on site, documents get lost in transit between the site office and head office, and project managers waste time coordinating paperwork rather than managing the build.
SignZA makes it possible to send a subcontractor agreement from site, have it signed on a phone within minutes, and maintain a digital audit trail — eliminating the delays and costs associated with printing, couriering, and chasing paper documents. The subcontractor receives a WhatsApp or email link, opens it in their browser, and signs using their finger or by typing their name. You receive the signed document instantly.
For variation orders, where rapid client approval is critical to keeping the project on schedule, SignZA removes the typical delay of printing, scanning, and emailing. Upload the variation order, place a single signature field, and share the link. The client approves it in minutes and you have a legally valid, timestamped record of the instruction — protecting your claim in the event of a later dispute.
Safety compliance documentation — site induction registers, risk assessment acknowledgements, and CIDB compliance forms — can all be signed digitally and stored in your SignZA dashboard. The Pro plan at R99/month provides 50 document signings — sufficient for most project offices managing 1–3 active sites.
