I`m in the planning stage for some products that would be delivered via standard reports -- probably PDF documents available for download or distributed by email.
I think that a money-back guarantee would enhance my value proposition, but I`m not sure how I will ensure that I don`t give money back to customers who actually are just trying to get my product for free. For one product, I have an idea for a 30-day grace period, during which I could probably learn whether or not they actually "consumed" the material in my report. For other products, I`m not so sure.
What experience have you had with money-back guarantees?
If your experience was with intangible products like information, how do you guard against this potential problem?
