Drag it
Open the schedule. Find the visit. Drag it to a new day and time. Keep Up checks for conflicts, shows you the new fit, and asks if it should message the customer.
Tell the customer kindly
Tick 'Tell the customer' and pick a tone — apologetic, routine, cheerful. Keep Up drafts a short message in their language. You approve. It sends.
Rebuild the day if you want
Moving one visit messed up the day? Hit 'Rebuild day' and the AI assistant suggests a clean re-plan. Approve all or some. Done.
Every drag is one-click undoable for 30 seconds. No-one panics about dragging to the wrong day.
