The ease of use, how it integrates with our CRM platform (Salesforce) makes this one go-to software for all aspects of my business! I am able to keep track of clients everywhere at once including client contact information AND their billing details if they are using Salesforce as well!! It's really easy just plugging everything together so there aren't any problems yet when we do decide what other features would be good additions down the road - but those things can always change haha ;) If anyone wants something simple or quick out of box solution then check them out.
We've been looking around quite awhile since everyone does similar services like us now anyways which leaves no need for more complex solutions unless someone needs certain specific functionality not included by default such as custom reporting etc.,.
