I believe that it's better for their long-term viability if they sell 1000 for $2000 instead of 300 for $4400.
My car mechanic charges $160/hr.
I’d guess they net 15% on average on that shop rate after accounting for all of the overhead. Some jobs will be high margin wins, some jobs will make a bit, some jobs will lose money.
The shop rate doesn’t just include labor, it also includes all of the overhead of the shop: equipment like lifts, alignment machines, tire machines, consumables, service writers, rent/mortgage, software, diagnostic tools, utilities, blah blah blah.
Btw I quote all residential electrical work at ridiculous prices because I don’t want residential customers, possibly you called a commercial oriented plumber first?
You'd think HN users aren't "most people"
Not even on HN!
