With the fixed rate and factor engine, you can use factors to increase or decrease the rental charge based on the total length of the rental period.

A fixed rate is a simple calculation of price x quantity. E.g. 2 x product at $10 for 5 days would be $20 since $10 x 2 = $20. Factors can then be used to increase or decrease this charge.

# Factors

The default entry sets the factor to 1 for the first day of rental and all others (‘to’ is left blank which means forever).

For example, to offer a 10% discount if a rental is two weeks or longer, you could do something like this:

From: 1 To: 13 Factor: 1

From: 14 To: Factor: 0.9

You cannot have gaps in the factor sequence and only the last factor entry can have a blank ‘to’ value.

# 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.

## 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.
