I like how easy it's super user friendly! You can use it when you are out of office too so no problem there. The mobile app also helps in viewing your invoice history whenever you need it but nothing yet as far as dislike goes. Would love for them to add more features such as multiple account management or integration with other billers would be great addition if they have plans to do this soon then we will definitely give feedback about additional services/features which could be added next time around.
