Automate booking before anything else
If you only build one automation this year, make it something around booking or scheduling. It touches nearly everyone who interacts with your business, it happens constantly, and it almost never requires judgment beyond checking whether a slot is open. Booking was the first thing I ever automated in my own business, and it is still the one I would recommend first to anyone else. That combination makes it one of the highest value places to start for almost any small business.
This matters because booking friction quietly costs you more than it seems. Every back and forth message is a small delay that can cool off someone who was ready to move forward, and every minute you spend manually coordinating a time is a minute pulled away from the actual work only you can do.
Try this today: if you do not already have one, set up a simple way for people to see your open time and book it directly, and start pointing people there instead of trading messages.
