Discussion: Upsell and Passive Income

There are a lot of easy ways for designer and developers to make some extra money or generate passive income.

For example, one could sell hosting, offer banner design services, create theme/templates, and much more. This type of thing can be a great way to get some extra money out of a client or help you earn some money when things get slow.

So, my question this week is…

Do you up sell any of your services when working with a client? (ie banner design, hosting, etc)

Do you have a means of passive income? If so, what is it? (ie themes, affiliate sales, etc)
