I like that it has been very flexible to use in its many different ways as my needs have changed over time! The user interface can be hard to navigate at times but this is likely due to having used other systems prior to using Abacus. As an Accountant / Controller we were able to track our accounts payable easily from one system to another. We also had the ability to keep up with all of our supplier invoices/payments too! This was ideal because most suppliers send their own files directly into Accounts Payable which made tracking them much easier than searching through emails or paper records!
