“RFPs are published so that organizations that might be qualified to participate can apply. They are invitations. That makes them particularly valuable for nonprofit organizations. It means that the foundation or government agency is ready to go forward with funding a particular issue. If you have a program in the works or even an established one that you still need to fund fully, an RFP can be a godsend.” - Joanne Fritz. https://www.thebalancesmb.com/the-basics-of-rfps-requests-for-proposals-2502484
