Invoice Payment Email Notifications
You can set up both advance and overdue invoice notifications for your clients through INSZoom's billing module.
Navigate to 'Billing' in the main left menu and click on 'Notifications/Alerts' on the left menu under 'Setup'.
Click on 'Edit' for 'Invoice Alerts for Clients' and input the day increments you would like the email notifications to send out to your clients.
NOTE: There are other email alerts regarding invoices that can be set up on this same page. These include editing or deleting an invoice and a change in address for an invoice payer.
