If your Customer/Supplier is not on the eInvoicing Network, you can add the ABN and then invite them to join the Network via Link4.
Go to "My Network" page, search the particular organisation and under the "Invite to eInvoicing" section, you will see if the ABN needs to be updated.
Once you have updated the ABN, you can click on the "Invite to PEPPOL" button and invite them to eInvoicing (clicking on the Invite to PEPPOL button will send an invitation via email to your Customer/Supplier to join the network).
You can customise the email invitation message, click here to see how.
