Client Payment Tracking - How do I?

How can I check if a client has paid or do I just need to check in my linked bank account?
Are there better ways to track this in Webflow or does anyone have suggestions?
Clients often need reminders to pay or will this happen automatically once they have their credit card added. Could not find too much information on this area.

@kevbaum Always when a payment is done you will receive a mail from Webflow
