This is top notch advise. Noone wants to be sold to. Selling our SaaS products, I found that the best way to close is to ask prospects to educate you about their problems(related to your product, of course). You don't need to lie, tell them you are trying to learn more on a specific use case for your product - and that they are doing you a huge favor by helping you with that! People usually like to help. If you're asking the right questions, they might actually close the deal for you.
