I co-built and ran a successful consulting company that was sold to a client many years ago, am now running another successful consulting. So I've been at this game for many years. And for what it's worth, tptacek's advice on billing, especially this advice on billing daily, is one of the foundations of our success in this business. When we were just getting started, a lot of tptacek's advice helped us to learn and grow what we are doing, and I don't think we would've been anywhere near as successful in growing, or in understanding the business, without it. Billing daily is a no-brainer. Almost every client is absolutely fine with it. This depends somewhat on the exact field and the exact client base you have, but if they're not fine with it, it's a sign that you're targeting bad clients and should change your aim.
