Shanli Liu recommends giving your product or service free to your first ten customers. You'll get authentic testimonials and case studies that dramatically shorten the sales cycle for paying customers after that.
If you're getting started, for you to get 10 customers who pay you with it never giving anything away for free is gonna take a long time. You getting 10 people to start working with you for free and then using the 10 testimonials you get there to then get your 11th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, 19th, 20th customer is gonna take you less time to get that 10 paying customers if you do 10 for free first of whatever it is that you sell.
