Starting point
Compare offers with matching duration, duties and visit counts, then check what each price includes. The lowest number alone does not explain service scope or additional terms.
during a month-end review
Compare actual duties with the agreed list and record necessary adjustments before discussing an extension.
a weekly review
Review completed and deferred duties and their reasons, then agree changes to priorities or time instead of repeating an unsuitable list.
Checklist
Selections are not sent or saved.
Before agreeing
Do not treat prices from a previous offer as applying to every customer or area; ask about availability and terms.
