To invite your customer to join Link4, first you must make sure that they are correctly categorised as a customer in Xero.
(1) Login into your Xero account and click on Contacts -> Customers:
(2) Check that your customer is listed in the customers list.
(3A) If your customer is not showing in the "Customers" list, check if they are in the "All" list.
(3C) Once they are added as a contact, you will need to create a draft invoice in order for Xero to categorise your customer as a "customer".
Now that your customer is categorised in Xero, Login to your Link4 account and go to the “My Customer” page.
(1) Select the customers you would like to invite to Link4.
(2) Add the ABN of your customer.
It’s recommended that you add the ABN of your customer as we use it to identify businesses in the Link4 network.
This pop-up box, as shown in the image below, will appear if you haven't included your supplier's ABN in your cloud accounting system.
Note: You will need to have an ABN before you can invite your customers to join Link4.
