We will see the list of all the clients, we will look for in this list the student to whom we want to modify one of the quotas. And we will click on the "Edit" button as shown in the image.
Once inside the customer card we will go to "Services" in the menu on the left and "Registration for Courses / Campus" in the window on the right, where we will see the list of all the schools to which it is registered, click on the "Edit" button as shown in the image.
It will open a window with all the information of the school, and in the bottom where are all the buttons, there is one that puts "View Payments", we will press on him.
Here we will list all the payments that the student must make and on what dates. In order to edit any of these quotas, we will click on the "Edit" button of the quota to which we want to change the price, as shown in the image.
We will open a popup window with the amount of the fee, which we will modify with the amount we want.
