A short check list staff will actually finish
Write the check as a short list your staff will actually complete on a busy Saturday — five fields that always get filled beat fifteen that never do. Decide which items need photographs and which do not. Set the preparation time per unit so the check has room to happen. Agree what counts as a note worth writing: existing damage and missing extras, not opinions about the customer. Write your deposit rule and your late-return rule in the words you will say out loud. Then run one weekend with the check before you make it the standard, and cut whatever nobody used.
No charges, deposits or damage assessment
It captures the moment. Everything that follows from the moment is your decision.
