Im an independent book developer, and in order to get my clients ideas in print form, a lot of moving pieces and a lot of people (designers, editors, marketers, writers, admin) need to work together smoothly.
Basecamp is an integral part of my business process. It gives my clients peace of mind - because they can see whats going on with their project. It gives me the ability to see at a glance which subcontractor needs to deliver what, when. Basecamp also helps my subcontractors to know exactly whats expected of them.
Since using Basecamp, my business has become simpler and more streamlined. Im able to focus on what I do best.
