Impact of Subscription Profile Attributes on Billing Summary
Different subscription profile attributes can have an impact on the Billing Summary.
Billing Frequency
Billing Frequency is the periodic interval at which a customer is billed at a time for the subscription. You can define the time units for billing frequency in Subscription Time Unit Mappings. You can find the Billing Frequency field on the subscription profile. The value entered in the subscription profile is defaulted to the subscription header and product and can be overwritten if required.
Consider the example of a 1-year subscription. Here’s how the billing dates are impacted by different billing frequencies:
Billing Frequency – Month
| Subscription | Start Date | End Date | Invoicing Rule | Period Start | Billing Frequency | Period Type | Billing Date | Billing Interface offset Date |
| Sub 01 | 01-Jan-2022 | 31-Dec-2022 | Advance | Service Start | Month | Actual | Period Start | <no entry> |
| Period | Charge Name | Charge Periodicity | Interface date | Bill from date | Bill to date | Amount |

| Sub 01 | 01-Jan-2022 | 31-Dec-2022 | Advance | Service Start | Quarter | Actual | Period Start | <no entry> |
Billing Summary:

Invoice Rule
The Invoice rule determines when an invoice should be issued for a billing period. It determines both the invoice date of billing sent to AR as well as the date when it is interfaced to Receivables. The two invoice options available are:
- Advance Invoice - Advance Invoice indicates that the customer is billed before the start of the billing period
- Arrears Invoice - Arrears invoice indicates that the customer is billed after the billing period
Based on the invoice rule, if the calculated interface date is in the past compared to the system date, then the system date becomes the interface date and the invoice date for all those billing periods.
The interface date of one-time charges follows the same logic as that of recurring charges.
The invoicing rule for usage charges is always arrears because you can’t bill in advance for usage charges.
Let’s consider the example of a 1-year subscription.
Here’s how the interface date varies for advance and arrears invoices.
Invoicing Rule: Advance Invoice
| Subscription | Start Date | End Date | Invoicing Rule | Period Start | Billing Frequency | Period Type | Billing Date | Billing Interface offset Date |
| Sub 01 | 01-Jan-2022 | 31-Dec-2022 | Advance | Service Start | Month | Actual | Period Start | <no entry> |

| 12 | Charge 01 | Month | 01-Dec-2022 | 01-Dec-2022 | 31-Dec-2022 | $10 |
Invoicing Rule: Arrears Invoice
| Subscription | Start Date | End Date | Invoicing Rule | Period Start | Billing Frequency | Period Type | Billing Date | Billing Interface offset Date |
| Sub 01 | 01-Jan-2022 | 31-Dec-2022 | Arrears | Service Start | Month | Actual | Period Start | <no entry> |

Billing Interface Offset Date
You can offset the interface date by a number of days using the Billing Interface Offset Date field on the Subscription Profile page. You can postpone the interface date by entering a positive value in the field or advance the interface date with a negative value. If the Billing Interface Offset Date is either zero or blank, then the interface date will not be updated.
Let’s consider an example of a 1-year Subscription. Here’s how the interface date varies based on the value in Billing Interface offset Date field.
Billing Interface offset Date = 12
| Subscription | Start Date | End Date | Invoicing Rule | Period Start | Billing Frequency | Period Type | Billing Date | Billing Interface offset Date |
| Sub 01 | 01-Jan-2022 | 31-Dec-2022 | Advance | Service Start | Month | Actual | Period Start | 12 |
The updated Billing Interface Date is the sum of Interface date and the Billing Interface offset Date value.
Here’s what the Billing Summary will look like:
| Period | Charge Name | Charge Periodicity | Interface date | Bill from date | Bill to date | Amount |
| 1 | Charge 01 | Month | 13-Jan-2022 | 01-Jan-2022 | 31-Jan-2022 | $10 |

Billing Date
The impact of the Billing date on the Interface date depends upon the Billing Date value you select – Period Start, Period End, Day, and Offset. This table describes the relationship between Billing date and Interface Date:
| Billing Date Value | Interface Date |
| Period Start | Start date of the billing period |
| Period End | End date of the billing period |
| Day | The day in the billing period |
| Offset | Interface date is postponed or advanced by the offset value |
Let’s consider the example of the same 1-year subscription as before:
If the invoicing rule is advance invoice and billing date is Period start:
| Subscription | Start Date | End Date | Invoicing Rule | Period Start | Billing Frequency | Period Type | Billing Date | Billing Interface offset Date |
| Sub 01 | 10-Jan-2022 | 09-Jan-2023 | Advance | Service Start | Month | Actual | Period Start | <no entry> |
Here’s the Billing Summary when billing date is Period Start:
The invoicing rule is Advance Invoice, when billing date is period start, the same billing period’s start date will become the interface date.
| Period | Charge Name | Charge Periodicity | Interface date | Bill from date | Bill to date | Amount |
| 1 | Charge 01 | Month | 10-Jan-2022 | 10-Jan-2022 | 09-Feb-2022 | $10 |

If the invoicing rule is arrears invoice and billing date is Day:
| Subscription | Start Date | End Date | Invoicing Rule | Period Start | Billing Frequency | Period Type | Billing Date | Billing Interface offset Date |
| Sub 01 | 10-Jan-2022 | 09-Jan-2023 | Arrears | Service Start | Month | Actual | Day = 3 | <no entry> |
Here, the invoicing rule is arrears so the interface date will be in the next billing period. Since the day is 3, the 3rd day of the month in the next billing period will be the interface date in the billing summary.

If offset is selected, the offset postpones or advances the interface date based on the value given in the field. This behavior is like that of Billing Interface offset Date where it accepts positive number of days or negative number of days.
If the invoicing rule is advance and the offset indicated is 12 days:
| Subscription | Start Date | End Date | Invoicing Rule | Period Start | Billing Frequency | Period Type | Billing Date | Billing Interface offset Date |
| Sub 01 | 10-Jan-2022 | 09-Jan-2023 | Advance | Service Start | Month | Actual | Offset = 12 | <no entry> |

Note: Similarly, you can calculate the interface date if the invoicing rule is Advance, and the Offset days are negative, and invoicing rule is Arrears and Offset date is positive.
If the invoicing rule is Advance and offset days are zero, the interface date is same as advance invoicing rule & period start.
If invoicing rule is Arrears and offset days are zero, the interface date is same as arrears invoicing rule & period start.
