A client signs your quote on their phone at a taxi rank and emails it back. Ten minutes, no printer. Then the doubt arrives: is that actually a signature, or have you just collected a picture of one?
For most of the documents a small business deals with, it's a real signature and it holds.
The law that settles it
South Africa has had electronic signatures on the statute books since 2002, in the Electronic Communications and Transactions Act, usually shortened to ECTA. The Act does two useful things. It says information in electronic form isn't second-class simply because it's electronic, and it recognises the electronic signature as a legitimate way to sign.
The definition is deliberately wide. An electronic signature is data attached to, or logically associated with, a document, which the signer intended to act as their signature. Nothing in there about pens, ink, styluses or scanners. A typed name at the bottom of an email, a finger-drawn scrawl on a phone screen, a tick in a box: all capable of being a signature.
What the Act cares about is not the shape of the mark. It's whether the person meant it.
Where an ordinary electronic signature is enough
The bulk of small-business paperwork sits in this space: quotes, service agreements, sales orders, NDAs, offer letters, consent forms, terms and conditions. No law demands a signature on any of them. They are binding because two parties agreed, and a signature is simply the evidence of that agreement.
Because no statute forces the issue, you and the other party are free to agree how you'll sign, and an ordinary electronic signature does the job. This is the whole reason e-signing works commercially: the majority of contracts were never legally required to be signed at all.
The documents that still need ink
A short schedule of exclusions sits outside all of this and still requires a handwritten signature on paper. The ones a small business is most likely to bump into are wills, the sale of immovable property, and long-term leases of land. Bills of exchange are also excluded.
If your document is on that list, no signing platform helps you. Print it, sign it properly, and keep the paper.
Signing is easy, proving is the hard part
Here's the part people skip. Nobody has ever lost a dispute because their signature was a PNG instead of a fountain pen. They lose because they can't show who applied it.
Take the common shortcut: someone crops their signature out of an old scan and pastes the image into every PDF that crosses their desk. It's a valid electronic signature in principle. It's also the easiest thing in the world to deny, because that image exists as a file that anyone with access could have dropped onto any document, at any time, and nothing in the PDF says otherwise.
Compare that with a signing process that captures the surrounding facts: which email address or phone number the request went to, when it was opened, when it was signed, from what device, and a copy of the document as it stood at that moment. The mark on the page might look nearly identical. The evidence behind it is a different world.
So the practical test for any document worth arguing about is not "is this legal", it's "if this person says they never signed it, what have I got?"
What to actually do
Send the document electronically, get it back electronically, and keep the whole trail rather than just the final PDF. Make sure the version that was signed is the version you keep, because a signature is only ever a signature on a specific document. And check your document isn't on the excluded list before you bother.
E·BIZI Papers does the trail part for you. You build the document, email a link, and what comes back is a finished PDF with a record of who signed it and when, instead of a signature image you have to take on trust.
