# Billing term, day and date calculation option, payment term
## .png?sv=2026-02-06&spr=https&st=2026-10-28T01%3A09%3A12Z&se=2026-10-28T02%3A09%3A12Z&sr=c&sp=r&sig=gz5nY3k8vm%2BwkOkX0krboWl%2F0jY2Qz5L6EB68HNXZ2w%3D)
## Fields that influence the invoice date
The determination of the invoice dates of an invoice schedule on a subscription record is conditioned by the fields:
- Billing term
- Day for date calculation
- Date calculation option
- Payment term
These fields are located on the **Subscription** object in the **Invoicing section**.
| Billing term | Picklist | - Allows you to define whether the invoice dates are defined in relation to:
- the start date of the invoice (in advance) or
- the end date of the invoice (in arrear).
Note: By default, the in arrear option is used. |
| Day for date calculation | Number (3,0) | - Depending on the option chosen (see below) the number indicated here allows you to add a deviation from this date or to indicate a fixed day.
- You must put a value in this field.
- It is possible to enter negative numbers.
- In the example we have chosen 10.
|
| Date calculation option | Picklist | - Fixed day before term: indicate the desired fixed day before the start date (in advance) or end date (in arrear).
- Fixed day after term: indicate the desired fixed day after the start date (in advance) or the end date (in arrear).
- Delta to the term:
- Day for date calculation is a positive number: delta of days after the start date (in advance) / end date (in arrear).
- Day for date calculation is a negative number: delta of days before the start date (in advance) / end date (in arrear).
|
Attention: If these fields are not visible on the subscription, they must be added to the page layout via the object manager, or the Lightning App builder for versions after the Summer'21.
### The impact of these fields
Here is an example that details the overall set of these fields:
| Billing term | Date calculation option | Day for date calculation | The invoice date is: |
| --- | --- | --- | --- |
| In advance | Fixed day before term | 10 | The 10th of the month before the start date. |
| In advance | Fixed day after term | 10 | The 10th of the month after the start date. |
| In advance | Delta to the term | 10 | 10 days after the start date. |
| In advance | Delta to the term | -10 | 10 days before the start date. |
| In arrear | Fixed day before term | 10 | The 10th of the month before the end date. |
| In arrear | Fixed day after term | 10 | The 10th of the month after the end date. |
| In arrear | Delta to the term | 10 | 10 days after the end date. |
| In arrear | Delta to the term | -10 | 10 days before the end date. |

### Diagram 1: in advance
### Diagram 2: in arrear
## Diagram 3: in advance and day for date calculation = -30
Note: If necessary, we recommend adjusting the date of the first invoice directly on the invoice record.
## Fields that influence the invoice date and the due date
Reminder: the calculation of the invoice dates of a billing schedule on a subscription record is conditioned by the fields:
- Billing term
- Day for date calculation
- Date calculation option
In order to take into account the invoicing terms *Payment in arrear* or *Payment in advance*, the field *Payment term* must also be taken into account.
The payment term can be found in the Payments section.
| Payment term | Picklist | - The agreed deadline for payment of the amounts due.
- Refers to a set of global values.
- X days net: X days from the start date.
- X days end of month: X days from the start date, at the end of the month.
|
Please note: If you choose the cash payment term,
- The billing term *Payment in arrear* behaves like the billing term *In arrear* and
- The billing term *Payment in advance* behaves like the billing term *In advance.*
### Example with cash payment
| Billing term | Payment term | Option for date calculation | Day for date calculation | Start date | End date | Invoice date |
| --- | --- | --- | --- | --- | --- | --- |
| In advance | Cash | Fixed day before term | 10 | 01/05/2021 | 31/05/2021 | 10/04/2021 |
| In advance | Cash | Fixed day after term | 10 | 01/05/2021 | 31/05/2021 | 10/05/2021 |
| In advance | Cash | Delta to the term | 10 | 01/05/2021 | 31/05/2021 | 11/05/2021 |

### Calculation logic
Example: First row of the table above
- Billing term: Payment in advance
- Payment term: 30 days net
- Option for date calculation: Fixed day before term
- Day for date calculation: 10
1. Calculation of the due date = start date as payment is in advance (payment is expected before the period covered by the invoice)
2. Calculation of the invoice date =
1. Intermediate calculation 1: 30 days net before the due date (Payment term).
2. The 10th before the date of calculation 2.a. (Date calculation option: Fixed day before term = 10).
3. Recalculation of the due date = invoice date + payment term.
