&gt; Don&#x27;t undercharge (especially if you go desktop).<p>This is incredibly important advice!  Marketing &amp; actually finding customers is the hardest part of the business, so if you only need a few customers, you&#x27;ll be way ahead of the pack.<p>I know someone who is selling a Photoshop Plugin for $100 and seems to be doing okay from it, even though that&#x27;s more than the price of Photoshop Elements itself!  If your product is valuable enough to your customer, they&#x27;ll pay for it.  If they&#x27;re earning $100&#x2F;hour &amp; your product saves them even two hours of work, it&#x27;s a no-brainer.<p>&gt; ... plus I have support emails to deal with.<p>Don&#x27;t forget this when considering your pricing.  Some percentage of your customers will always need support, and you need to account for all those 15 minute blocks where you&#x27;re helping people.  If you&#x27;re selling a $2 app, a single support email wipes out your earnings from several sales.
