Once you have set up an account using Clio Payments or Clio's classic online payments feature, your clients will be able to pay the bills that you share with them through Clio Connect.
When the client opens the bill, they can click the "PAY BILL" button at the top right.
In the "Make a Payment" window, your client should add their credit card information and address (must contain a valid State). The client can then modify the amount in the "Payment Amount" field to make a partial payment if desired.
