I'd rather not get into project #'s but I will certainly say that every time I do a project I learn something new about how to better price future projects. This project was about a 3 1/2 month voyage that included a master bath remodel, the master closet (which included removing separating walls, relocating doors, repairing the floors and ceiling, etc) along with all of the other builds. When I did my estimating, I managed to not include any fuel/travel charges...this was a 130 mile round trip daily commute. My truck averaged about 13 mpg when I wasn't hauling my trailer and fuel was about $3.70/gallon at the time. Do the math on that one...big oops on my part. It wasn't my first rodeo but just an error that definitely dropped #'s off my bottom line...we all make mistakes, it's how we learn from them!
Also, through the years, I've found what works for me is to only offer specific things. For example, I don't offer epoxy slides or Blum soft close or ball bearing, I only offer Blum soft close (unless a specific task calls for a different item). This way, I don't have to offer multiple styles of pricing with too many options, nor do I have to work with inferior products just to satisfy a slightly lower price point. The greater the options you offer someone, the more confused people get. I figure if I can offer what I feel is the best, nobody will ever walk into my clients house and say something along the lines of "you don't have soft close on your custom x? I do on my Ikea x!".
I hope this mentality helps at least one person!
