Automatic invoice generation is available for all of our business clients. For automatic invoice creation go to Billing - Make a Payment page. Choose an amount for automatic payments, the date of the month, and a remaining balance upon reaching which an invoice will be generated automatically and sent to the email address you have registered with.
We recommend setting up remaining balance and invoice generation notifications for employees responsible for telephony and/or financial department. They can also receive important notifications in popular messengers - Facebook Messenger, Slack, or Telegram. To set up notifications go to Settings - My Profile - Notifications and add recipients.
