Just a few criteria to think through the value of your product. Value transcends monetary value, and isn’t always quantifiable. Value is perceived worth; that is ultimately what we base our decision to buy or ignore on. Value is also what we use to decide whether a product is worth more or less than the asking price.
Build value into your product; telling customers you can’t (or not doing so) because of internal process or limitations inherent in the system is a good reason for them to find someone who can overcome those obstacles. Overcome those obstacles, and they won’t have reason to leave; even if you are far more expensive than the ‘competition’.
