You sent the quote days ago. Now it is just sitting there.
You have already done the work. The site visit, the measuring, the evening writing it up.
Nobody enjoys ringing about money, which is exactly why quotes go cold and stay cold.
I follow up the quotes you send. That is the whole job and it is the one most people quietly skip.
A quote that goes quiet is not a no. It is usually somebody who got busy, and nobody ever asked them again.
So I ask. Once, properly, at a sensible time, and then again if it is still open.
I am not trying to talk anybody into anything. I want a yes, a no, or a date in the diary, because all three are worth more to you than silence.
If somebody says no, I take it well and I stop. That is the part that keeps you looking professional, and it is the part that gets you the next job off them in two years.
You are not renting software. You are putting somebody on the job who does one thing properly and does it every time.
