So when there is 1 invoice that has not been paid and has passed the deadline that has been set, the customer can not make purchases again.

Step 1. Open more menu properties through setup menu
Step 2. Select on contact then fill the maximum days and save
II. Maximum overdue days on contact menu
Add new customer and select Sales & Pricing tab
*Note: When ever you create a new customer or edit the default days overdue should same as you set on your configuration
