If your admin has created a fee for you or your child, then you will receive a notification to pay the fee. You will receive an additional notification on the day the fee is due if it has not yet been paid.
Here's the simple steps to getting that fee paid. (This applies to teams who have enabled payments in the app).
Head into your Heja app and click the Fees tab
In the top right corner press Your Fees (a red badge will indicate that you have a fee)
You will see a total of how much the fee + service fee comes to.
Click on set up one click payments
You can then add your card details and confirm the payment.
You also have the option to pay the fee outside of Heja to the admin, and they can manually mark that you have paid the fee in the app.
