How to digitally sign documents using your phone or tablet

In this article we will explain how to digitally sign invoices and other documents using the STEL Order app for smartphones and tablets.


The app allows users to collect signatures, which are then added automatically to any invoice or document that is currently open. The result is identical to a paper-signed document, and it can be shared via email or printed at any time.

Follow these steps to digitally sign any document:

  1. Open the document that requires signing.
  2. Press the icon with 3 vertical squares.
  3. Select the [Sign] option.
  4. Add the name and ID number of the person or the organisation signing the document.

Once this is done, the signature will be automatically added and saved to the document which will then be stored in your STEL Order database.
