Ask What is a freelance skill that lends itself naturally to cross-selling complementary services?

[Brendan]

Some skills almost come with a built-in list of things clients will need next, which makes it much easier to grow an income without constantly looking for new people to work with. A copywriter, for example, can naturally move into email strategy or content planning because the same clients who need words also need a plan. Knowing which services sit beside your main offer can change how you think about your business. What skill do you think opens the most doors for selling related services?
