The quote goes out on Monday.
Then nothing.

No reply, so the owner decides the answer is no.
Most of the time it isn't no.
It's busy.
It's a partner who hasn't looked yet.
It's an email sitting under forty others.

One short message a few days later.
"Did this make sense? Happy to adjust anything."

That's the whole system.
I'm still surprised how few businesses have it.
