I like that they have so many options to help you get debt paid off as fast as possible! It was easy at first but then they stopped working correctly. My client would log in multiple times each day just trying to figure out how their payments were going. They also didn't seem to be able to create new accounts which made it difficult to assign them other clients or customers since we did not want multiple users logging into one account. We used Debtor Daddy because our current invoicing system only allowed us to pay bills online if someone logged onto an email address associated with us. If no one signed up for billing than we couldn't do anything. Using DebtorDaddy gave us access to bill any customer who wanted to use our services without having to wait to see if anyone signed up from it.
