How to setup pricing for an Electrical Contracting Residential Service Provider?

Hey everyone,

I'm fairly new to the residential electrical service side of the industry and I'm trying to get my pricing dialed in.

One thing I've been struggling with is pricing service calls. Sometimes I feel like I'm pricing too low and leaving money on the table, while other times I worry I'm pricing too high and potentially losing work.

For those of you who have been doing residential service for a while:

• Do you use flat-rate pricing or time-and-materials pricing?
• Do you charge a diagnostic fee, truck fee, or travel fee?
• Is there a pricing system or price book you would recommend?
• Did you build your own price book, or did you purchase one from a service like Profit Rhino, The New Flat Rate, or another provider?

I'm looking for a system that's consistent, profitable, and fair to the customer.

I'd appreciate any advice from those who have already been through the learning curve.

Thanks in advance!
