Rate Engine is part of Rental & Fleet Utilisation in Windward System Five. System Five includes 6 documented capabilities here — all 6 optional. Trades that lean on it include Powersports Sales Service & Rental, Party & Equipment Rental Businesses, Medical Supply Sales, Service & Rental.
These 6 capabilities sit within System Five's 1287-capability documented set — a selection, not a ceiling.
Stop charging for hours you were shut
Rental hours stop accruing while the business is closed and nominated days can be marked non-chargeable, so a machine out at 4pm and back at 10am the next morning bills as three hours rather than a full day.
Quote a rate that holds all hire
Only rates valid across the whole contract term are used; if an hourly rate is not valid every day of a week-long hire, the next lowest qualifying rate is applied instead.
See what the hire rates were back then
Supervisor mode exposes a dated history of rental rule settings; selecting a date shows the rules exactly as they stood then.
Price hires the way your yard does
An unlimited number of rules, system-wide or specific to a sub-category, of type Regular, Minimum Charge, Depreciation as a percentage of the amount charged, Manual for fixed price-per-period deals, or Quantity Discount. Each rule calculates on one rate or multiple rates and can carry a grace period and full-day-at-start-of-day handling.
Prove there are no gaps in your rates
A validation tree tests every month, day and hour of the rate calendar and flags overlapping periods and uncovered gaps, drilling down to the exact hour and the specific periods at fault.
Charge different rates by day and hour
Rental rates are driven by named time periods defined down to month of year, day of week and hour of day, ordered in a tree that controls how they present on the item's rental rates tab.
