The generateInvoice class does more than one thing. In order to improve code maintanability and extensibility, it is recommended to use Extract Class refactoring technique, since this class launchs the applications as well as creates the frame for the invoice.
It is recommended to have multiple classes, each focusing on one single responsibility.
Login button logic from Login class may be using unnecessarily complex conditional statement, thus affecting code maintainability and extensibility, as well as readibility.
Suggest are to use refactoring techniques such as Extract Method and Move Method
Primitive types representing days in Sale class may difficult code maintainability.
A class representing a month can be created and the logic moved there to ensure data encapsulation and even move through month types depending on days cardinality. Or even better, use object that already exist to attack the problem.
Suggest are to use Replace Data Value with Object refactoring technique.
