Preventative customer support. Your goal should be to minimize your customer support requirements. For the past two years I've treated every customer inquiry to my business as a bug requiring a fix. If someone asks me for additional information about a product, I add a section to that product's description page or, alternatively, make the existing content clearer. If someone has trouble with a download, I improve the instructions sent with my payment confirmation email and perhaps increase the font size of the most critical links in the admin area. In-line instructions, such as those used by the 37 signals team, help greatly in this respect. Over time this has worked and customer support requirements have dwindled, and with less emails to answer per day you can afford to be away from a machine for longer.
