This field indicates the invoicing method for the charges the service provider applies for each intervention.
Several expense invoicing formulas are suggested as standards:
Charges included: This formula means that whatever the amount of the committed charge, no additional invoicing related to the hourly rate will be applied by the service provider.
Fixed-cost contract: This formula signifies that whatever the committed charge amount, an identical sum will be systematically applied to each intervention invoicing. The "Expense valuation" fields is used in this case to enter the fee amount applied to each invoice.
Actual mileage: This formula means that all the charges will be invoiced on the basis of receipts. The invoiced amount related to the charge will be systematically equivalent to the sum actually expended.
As far as any visits carried out with vehicles, these will be re-invoiced on the basis of the number of miles undertaken. The "Expense valuation" field is used in this case to enter the amount applied for each mile/kilometer travelled.
Actual time spent: This formula means that all the charges will be invoiced on the basis of receipts. The invoiced amount related to the charge will be systematically equivalent to the sum actually expended.
As far as any visits carried out using vehicles are concerned, these will be re-invoiced on the number of hours for the trip. The "Expense valuation" field is used in this case to enter the amount applied for each hour elapsed and started.
