There should be pages to display information depending on the application/payment statuses:

• Waiting for confirmation (#11).
• Payment (optional; #9, #19).

So, the generic application stages are:

• created (expected confirmation): Creation of a new application.
• confirmed (expected payment -- optional): Confirmation via email.
• paid (completed): Payment (via invoice -- status chnges by admin; via stripe -- processed automatically).

State should be tracked by session.

These options should be available to edit in the admin panel.

These parameters should include:

• Only known emails allowed to apply #12?).
• List of allowed emails.
• List of emails to allow free access (#9 .
• etc

Applications should be confirmed after their creation.

The applicant should receive an email with confirmation link/code (?) and will have to confirm just created application with these.

After that the application status should be changed to 'active'.

See issues:

• #21

The app optionally (there should be a switch in admin) can allow only known email to make applications (a list of emails should be available in config).

Some emails (another list in config) shouldn't pay for the application. (The payment step should be optional.)
