With the weeks and subs weeks rate engine, you can specify that additional weeks are charged as a percentage of the first week’s price.

# Charging periods

Charges for this rate are calculated as a percentage of the weekly rate. For your reference, the leading rental period is listed here as 100%, i.e. the rate you entered against the product.

In the “Subs weeks” field, specify the percentage you’d like to charge for each week after the first week.

For example, if you set subs weeks at 50% and you add 1x product with a rate of $100 to an opportunity that’s three weeks long, the charge will be $200. This is $100 (one week) plus $50 (2x subs weeks).

# Options

## Day type

**Calendar day**The number of days to charge is based on whole days; the start & end times aren’t taken into consideration.

**24 hour clock**The number of days to charge is based on 24 hour periods; the start & end times are used to calculate rental charging.

For example, a rental that starts January 2nd at 11am and finishes on January 3rd at 9am would be considered two days rental when using “calendar day” since it falls over two whole days, and would be one day of rental because the end time is earlier than the start time.

## Rental days per week

Use this option to determine whether weekend days are considered chargeable. If you do not charge for Saturday or Sunday set this to 5, otherwise leave at the default value of 7.

## Minimum rental weeks

The minimum number of weeks to charge.

## Leeway minutes

This option is only used when the day type is set to 24 hour clock. It adds a grace period or tolerance to the end of a rental.

For example, if a rental that starts January 2nd at 11am and finishes on January 3rd at 11:30am then the total rental period is 1 day and 30 minutes. This is considered two days of rental charge. However, if you set 60 leeway minutes then the same period would be considered one day of rental charge as 30 minutes is less than the leeway minutes.
