I like that it's in Cloud, which means all of my team members are able to access everything at once so we don't have wait for each other when submitting documents etc.
As mentioned above they also provide templates so you do not need an expert person/knowledgeable about this specific builder field who knows how to fill out forms properly to know what information needs to be provided by your client or subcontractor. This has been helpful with our project managers but sometimes some clients will ask questions and then change their mind during contract negotiations if there was any "mistake" made prior (ie missing items from previous meetings) - which could lead them back to another form filling website such as Google Forms. Keeping track of payments between multiple parties.
