Please Help! How to Integrate account login and member areas, & how to edit

Hi! I am trying to set up a member area where a client would be able to sign in to see upcoming deadlines for subscription payments, but when logging in, it just takes me to my account and not a member area. How would I go about setting up a login for the member areas? And how can I edit the member area to show deadlines on payments? (are payment options something that show up automatically in the account login area?) Any tips or advice is helpful! Thank you in advance!
