Billing
Scheduling invoices going out the day work is done without a whiteboard
invoices going out the day work is done sounds simple until you are running hundreds of properties on it and every one has drifted.
Whiteboards and spreadsheets fail at the same point: they hold what you planned, not what happened. One rain week, one sick crew, one customer who skipped, and the plan and reality separate for good.
What actually works is a schedule that knows when each property was last done and when it is due — so the next visit is calculated rather than remembered.
The office job on top of that is small but daily: confirm tomorrow, move what must move, tell whoever needs telling.
Get that right and billing becomes predictable — you know what next week looks like, and so do your customers.
