I like that it can be used as an app, website or mobile device to help with compliance requirements such having proper tags for web-to-(W2)BID (Business Information Day). That is what we use most often at my job - so far seems great! Not much more than others have mentioned in other reviews; just make sure you follow all rules from beginning of project through end process if using this product/service along side W9s / 1099's etc., otherwise there could possibly some issues down stream when trying resolve them later after they are already live online & published without notifying anyone until things go wrong? Just do everything right up front during planning phase before anything goes into production mode!!
