NOTE: This only pertains to V1 Billing, NOT to our new V2 Billing (if you have Payment Plans, you have V2 Billing). Auto-Pay settings are done within the Payment Plan settings.
It's simple to adjust your automatic payment settings. These are set at the company level. Head over to My Company:

Step 1
Click on Payment Settings and choose one of the three options under "Auto-Pay Settings." You can allow customers to opt in or out of Auto-Pay, force everyone to have Auto-Pay on, or hide Auto-Pay altogether.
Here is also where you can decide your Payment Fees (i.e., Convenience Fees for ACH and/or Credit Card payments passed on to your customers).

Step 2
Scroll down to the heading "Auto-Processing Schedules." Check this box to turn Auto-Pay on. NOTE: This is a COMPANY setting, so if you turn it off here, you turn it off for everyone in the Company.

Step 3
Adjust your Auto-Pay frequency (choosing monthly or weekly). You can also pick every two, three...up to 12 months/weeks. Select the day of the month or the day of the week. We allow you to customize when Auto-Pay happens.
And if you have someone who needs to pay on a different schedule, that's okay! Simply set up their own Auto-Pay schedule.
Step 4
Set your start date by clicking the button. The schedule you set will auto-populate, so you can see exactly when payments will be taken out.
