The ease of use for our customers to be able to connect with their accounts receivable team via phone or email. It's also very user friendly when you are setting up your account. I think that having more options for customizing reports would help make it easier for us as well as our clients to understand what they can expect from us. We were looking for something that was easy to learn but still had all the bells and whistles we needed to run our operation efficiently. Infosourcing has given us everything we need plus some!
