What process has saved you the most time in your business?

For me, having a simple job checklist has saved the most time. Instead of relying on memory, every job follows the same basic steps—from confirming the appointment and preparing equipment to doing a final walkthrough before leaving. It reduces missed details, keeps everyone on the same page, and cuts down on follow-up calls because customers know what to expect. It wasn't anything complicated, but documenting a repeatable process made day-to-day operations much smoother.
