You’re not an employee so no performance reviews or line management and you are responsible for running your own company, but at the same time many contracts will be working with teams of permanent staff for 6 months or more so it’s not like you are off totally on your own having to invent new products or hunt for projects. I’d guess the remuneration can match that of a manager after you’ve been doing it for a while, but you’re essentially a technical expert who’s expected to be able to hit the ground running quickly and add a lot of value at each client.
My impression is that demand for good contractors outstrips supply right now (it can make sense for companies with fixed budgets or tight timelines to hire contractors despite a higher per-day cost) and the business side really isn’t that complicated, so it is a fairly well trodden path by good developers at a certain point in their career. Of course, if you are someone who feels like they benefit from having the company structure (eg in terms of management, training, etc) or doesn’t like changing company fairly often it’s probably not for you!
