As a marketing agency, we’ll appreciate the recurring invoice feature within RingTonic. Link our PayPal or Stripe account and RingTonic will automatically bill our client based on the amount per call we'll like to charge them or a flat rate fee. Whatever we decide works best for our agency.
Option to even set smart filters to only charge for calls that match a certain duration or filter out duplicates. This can make running a pay per call or lead generation agency easy, by automating the busy work.
