Create orders with multiple charges featuring annual prices and unaligned billing periods, resulting in varied invoice amounts.

1. Enable the Annual List Price settings.
2. Create four recurring product rate plan charges with the Flat Fee Pricing charge model.
3. Create and activate an order with four subscriptions to the four charges, with the total amount of $70,200.00 and different terms of 12 months.

   After the order is activated, you can get three invoices.

   Invoice Item 4	04/01/2022	07/31/2022	$266.67

   The following table lists the allocated amount and service period of each invoice item in the second invoice with invoice number INV002.

   Invoice item	Service start date	Service end date	Amount	Total amount
   Invoice Item 1	05/01/2022	09/30/2022	$12,300.00	$23,399.98

   Invoice Item 4	08/01/2022	12/31/2022	$266.66

   The following table lists the allocated amount and service period of each invoice item in the third invoice with invoice number INV003.

   Invoice item	Service start date	Service end date	Amount	Total amount
   Invoice Item 1	09/01/2022	12/31/2022	$12,300.00	$23,400.01
   Invoice Item 2	10/01/2022	01/31/2022	$7,166.67
   Invoice Item 3	11/01/2022	02/28/2022	$3,666.67
   Invoice Item 4	12/01/2022	03/31/2022	$266.67

   The subscriptions are billed with the billing target date: 1 April 2022, 1 August 2022, and 1 December 2022. The total invoice amount is $70,200.00, and it is not evenly distributed into 3 invoices. The first invoice has an amount of $23,400.01, the second invoice has an amount of $23,399.98, and the third invoice has an amount of $23,400.01.

   The amount displayed in the Amount column for each invoice item is calculated based on the following formula:

   (Selling price ÷ Total billing periods) × Past billing periods - Billed invoice item amount

   The amount displayed in the Total amount column is the sum of all invoice item amounts in this service period.

   For example, the amount of the second charge line item in each invoice is as follows:

   • $7,166.67 in INV001 $7,166.67 is the rounded value based on the formula of (21500÷3)×1. In this formula, 3 represents the total number of billing periods, and 1 represents that this is the first billing period of the year.

   • $7,166.66 in INV002 $7,166.66 is the rounded value based on the formula of (21500÷3)×2-7166.67. In this formula, 2 represents that this is the second billing period of the year, and 7166.67 represents the billed amount for the first billing period.

   • $7,166.67 in INV003 $7,166.67 is the rounded value based on the formula (21500÷3)×3-(7166.67+7166.66). In this formula, the first 3 represents that there are three billing periods in total, the second 3 represents that this is the third billing period of the year, and (7166.67+7166.66) represents the total billed amount for the first two billing periods.

   The sum of charge C2 from the three invoices is 21,500.00, which is the calculation result of 7166.67+7166.66+7166.67. That is, the charge C2 has a price of $21,500.00 per year.
