This is definitely a way better approach than hourly billing, for sure.
On the flipside, stating daily billing is not much different than hourly since the client will just divide by 8 (usually). I stated my daily rate after hearing it from you and Patrick and Brennan Dunn, and one client just said - ok so your rate is "$xxx" per hour?"
My point is that daily billing is an improvement over hourly, and with your approach of an overall fixed price and also daily that's a great approach, but the client still knows a daily rate is essentially hourly. A better approach is retainer pricing if not a fixed one-time project!
Even if your client does the division --- and many won't, because, remember, it's usually not their money they're spending, so what really matters is whether the number you presented fits into the abstraction of their budget --- if you're going to negotiate, you're better off negotiating in a frame where a $100 difference is insignificant to your outcome than one in which a $100 difference is devastating.
