For long-term rentals, Ace Drive uses a 30 day calculation. The first month’s rental will be billed in full according to the start date, and the second month will be billed prorated according to the end date. Subsequent billings will start on the first of each month. For example, if the rental begins on 15 June 2022, the first month’s bill would be from 15 June to 14 July 2022 and the second month’s bill would be from 15 to 31 July 2022. Subsequently, rental bills would be issued every first of month starting in August.
