The ease of use, how quick I was able to get up-and running with it in my organization; as well its capability being customizable within each department/area that needs specific functionality (i'm looking at you - database!). Some areas could be streamlined or improved upon but overall this tool has been very beneficial thus far! It's helped us keep track all our grants received & awarded through out various funders we are involved wtih throughout Florida so they can easily see what projects have come from their area specifically etc.. I like that it integrates with our website, allowing us to easily track donations via PayPal. The interface can feel clunky at times but this may be due in part to my own inexperience using such a program. We realized we were missing several opportunities to raise funds from donors who are not already supporters of our organization- so many people gave by check only! This has really made an impact for our organization as well as our donor database.
