Pros
I like that I can work from home, virtually from my own office. The on-the-job training is excellent; I improved greatly as an editor. When the money is good, it's great.
Cons
The content media coordinators do not answer the vendors' emails, which can be frustrating. CS does not pay on time, though it has the money upfront from the customers. It says it processes invoices on the due date and pays a week to two weeks later. This doesn't happen. Oftentimes, the invoice is processed a few weeks later and the vendor is paid a week to a month after that. Some months, the work flow is great; others it's nonexistent. The pay is based on the manuscript's word count, instead of the word count *and* the condition of the manuscript. For example, some manuscripts are in great condition, while others are English-as-a-second-language messes. It's the same price for both, if the word counts are the same. Thus, you could be making $5 per hour or $35 per hour, based on the manuscript's condition. My advice to new freelance editors: I've seen work dry up in an instant at many of these editing companies, so beware when signing a contract. Remember you're an independent contractor, so you have to pay your own taxes; save to do so.
