Yes, pages of them. Multiple pages of security questions, ciphers used, how data is stored, when is it encrypted, etc. I filled out a 20 pager once. As the company got better and more mature, we had a bunch of canned answers to make it easier and faster....
Entire (excellent) start-ups exist to fill the role of 'RFP library' so that you don't have the whole sales team rewriting the same answers 100 times a year. Loopio saved me hours in the last role I was in that had them - even if you do have to edit some of the responses from colleagues you're not sure passed 9th grade English.
Any other startups you can recommend? I'm filling in my first RFP in a decade and answering what they mean to ask with the questions rather than answering questions literally is not something that comes easily to me.
Plus coming up with an answer to the vague question on "describe your project methodology" (I build what you want, it works - nope, they expect half a page). Or the 3 questions on project management systems and communication software choices that to my reading should have the same answer.
