Charge your clients for those fees needing to be paid immediately (think application fee or security deposit) - no need to wait until the end of the day.
Navigate to your Clients tab > Client profile > Fees/Credits > Add Fee/Credit
Select a fee from the dropdown or add a custom fee to be charged at midnight tonight.
Once the fee has been added, navigate to the Statement tab in the client profile.
Select Charge Now under the Pending fee that was just added.
Note - if no action is taken, pending daily charges will continue to charge automatically later that night.
