Same here, only the EC can pull any electrical permit, which makes sense.
Lefty, I'm still learning too, even after 20 years, and plan on continuing my education for as long as I'm twisting wires together. I have found that "less is more" when supplying bid, estimate, proposal docs. Certainly, we need to include all important wording, etc., though.
When I get one of my vehicles worked on seeing the line item breakdown just annoys me, again, just tell me how much it is going to hurt and I'll pay you. My honest opinion, is that if a customer is not asking to see your math, don;t show it to them. If, however, you need to show them something to win the job over someone else, than you may be better served to sell them. The more you show the customer, the more they tend to pick your numbers apart, and want to haggle.
Selling bids is an art, selling anything is an art, it pays to take notes on what works and what doesn't. The BIGGEST thing I have learned and implemented here is to keep your mouth shut, as someone has said here before, "the first person to open their mouth looses"! If we are honest and competent, our prices are what they are. We need to get over feeling guilty for charging what is required to do a professional job, stay in business, and to grow our businesses.
Best wishes!
