You will need to log into your clinic account and click on Billing at the top of the page.
Select the number of tokens you would like to purchase and click Purchase Tokens. You will then be taken to a paygate where you can add your card details and pay for the tokens.
Once you have made your first token purchase, you will be able to turn on Auto top-up. This can be done by selecting the amount of token you would like topped up and shifting the Enable Auto top-up button to ‘Yes’.
