Brian, I never said I had all the answers. I'm trying to explain clearly what flat-rate is and correct misconceptions. Unless you were keeping the books and writing the checks at your previous employer, there's no point in speculating how well that business operated. I'll be more than happy to discuss first-hand personal experiences in business.
Instead of being so defensive about T&M, explain specifically what the benefits of it to you are, like I've attempted to explain our flat-rate system.
My problem with T&M is; You can only bill actual hours worked, customers are more likely to question your pricing, and its harder to sell. Feel free to discuss those items and tell my how it works for you.
We've had no problems with commercial customers using flat-rate; in fact many of them prefer this method of pricing.
At a recent contractor dinner meeting, the question of why some guys like T&M, and the number reason was they did not have to estimate T&M , so it appears they would rather lose the advantage of contract pricing, and profitable estimated projects, rather then learn how to estimate for profit.
