The question that sorts the list
Every alternative above except one is a different arrangement of the same deal: better screens for work your office still does. That deal is worth taking when you have a great office manager and your bottleneck is organization.
If your bottleneck is that leads text at 9pm and nobody answers, that quotes go quiet, that follow-up happens "when there’s time" - a different calendar won’t fix it. Speed will. Owners see up to 5× more leads become jobs when first replies drop from hours to seconds, and that’s the specific thing Robinline was built to do.
