Contract Usage Bills are the bills that are added to a contract to charge for work carried out under the contract. The bills are recorded against an account for a contract.
The contract bills are displayed in the Contract Usage Bills window.
You can enter the following information for a bill:
Contract ID - This is the ID of the contract to display the bills for. If the Contract Usage Bills window is opened from the Contract Module window, you can select the contract ID. If the window is opened from the Contract window, the Contract ID will be automatically selected for you.
Bill From - This is the date of the start of the billing period.
Bill To - This is the date of the end of the billing period.
Units Consumed - This is the amount of the units that have been consumed during the billing period.
Consumption Rate - This is the rate that the consumption units for the bill are to be charged at.
Demand Amount - This is the amount of demand units that have been consumed during the billing period.
Demand Rate - The rate that the demand units for the bill are to be charged at.
Bill Amount - This is the total bill amount, calculated as the Units Consumed multiplied by the Consumption rate, plus the Demand Amount multiplied by the Demand Rate. If you change any one of the four fields that are used to calculate the Bill Amount, the Bill Amount will be recalculated. You can overwrite the Bill Amount if you wish.
Other Cost - This allows you to enter an additional cost for the bill if you need to include extra cost that is not covered by the consumption units or the demand units.
VAT - This is the amount of VAT (Value Added Tax) calculated as the Bill Amount plus the Other Cost, multiplied by the VAT rate. If the Bill Amount or the Other Cost change, the VAT will be recalculated. You can overwrite the VAT if you wish.
Total - This is the total cost, calculated as the Bill Amount plus the Other Cost plus the VAT. You cannot edit the Total amount.
