Example 3

In this example, you set up a fee billing line using the percent of cost method and you select the Cumulative check box. You generate one invoice, change the percentage, and then generate a second invoice.

This table describes how the system calculates the fee for the first invoice:

Percentage	Accumulated Invoice Amounts (current invoice)	Accumulated Invoice Amounts (previous invoices)	Fee Amount from Previous Invoices	Calculation	Fee Amount
15	600.00 USD	0.00 USD	0.00 USD	((600 + 0.00) x .15) – 90.00	90.00 USD

This table describes how the system calculates the fee for the second invoice, after you change the percentage:

Percentage	Accumulated Invoice Amounts (current invoice)	Accumulated Invoice Amounts (previous invoices)	Fee Amount from Previous Invoices	Calculation	Fee Amount
20	800.00 USD	600.00 USD	90.00 USD	((600 + 800.00) x .20) – 90.00	190.00 USD
