CS platform integrates with billing systems to track the latest status of open invoices, renewal dates, collected amounts, and other financial metrics to compute the customer success function’s bottom-line value. Granted that not every CS action ̶ such as support for new sales and marketing initiatives ̶ translates into quantifiable gains, CS platforms manage clear bottom-line impact through renewals by CSMs.
