Some things I would be interested in knowing
-Do you use serial numbers? (I've thought about this, but what is to stop someone from simply bypassing this step, by simply removing that part of the code?)
-Do you jumble the code or anything like that
-What do you do about upgrades (Free for x months/free forever/flat fee/etc)
-What do you do about support?
-Do you use a forum or anything like that so that customers could contact each other?
-Anything else you think would be interesting/useful
Thanks!
"What do you do about upgrades"
"What do you do about support"
Your questions are very interesting ones. I think the answers will vary wildly depending on what is being sold (e.g. small website development vs large scale enterprise-wide product installation and integration services vs off-the-shelf downloadable software...). Possibly you'd get more responses from users who look at the "Professional Webmaster Business Issues" or "Ecommerce". (I think Jatar can move this thread there is you ask him nicely)
