The process

Signing a document takes three steps

  1. Upload the document

    Upload your contract as a PDF and place the signature, name and date fields where each party must sign.

  2. Invite your signers

    Each signer receives an email with a secure link. They review and sign from any device, with no account required.

  3. Everyone gets the sealed copy

    When the last signature lands, the document is sealed with a digital certificate and every party receives the final PDF with its audit trail.

Frequently asked questions

If your question is not answered here, email [email protected] and the team will come back to you.

Is an electronic signature legally valid in South Africa?
Yes. South Africa's Electronic Communications and Transactions Act recognises standard electronic signatures for ordinary business agreements. A small set of documents, such as wills and transfers of immovable property, still require other formalities, so confirm with your attorney for those cases.
What kind of electronic signature does Mongwalo produce?
Mongwalo produces standard electronic signatures under the ECT Act. It does not produce advanced electronic signatures, which require an accredited authentication provider.
What documents can I sign with Mongwalo?
Mongwalo suits everyday business contracts such as NDAs, supplier agreements, employment letters and lease agreements. Upload a PDF, place the signature fields and send it for signing.
Do the people signing my document need an account?
No. Recipients receive an email with a secure signing link and can review and sign the document directly from that link.
How do I know a signed document has not been changed?
Every completed document is sealed with a digital signing certificate and carries an audit trail of who signed, when and how. Any change to the sealed PDF after signing invalidates the seal.
