What it is
A catalogue of the specific day of the month on which payment is settled and of where the due date starts counting from. Useful for customers with a fixed collection day (for example, always the 15th, always the 10th).
What it is for
The payment day works together with the customer's payment terms to calculate the due date of each invoice. The payment terms provide the credit period in days; the payment day decides the fixed day of the month the payment falls on and from what point the count begins.

Key concepts
Terms that appear on screen, with their exact wording.
- Payment day: recurring payment setting that establishes the day of the month on which a debt falls due and the cycle used to calculate that due date (from the invoice or from month end).
- Calculation cycle (field Calculate due date): the basis that determines when payment falls due. From the invoice date starts the count from the issue of the document; From month end starts it from the last day of the month in which it was issued.
- No fixed day (0): a special setting where the payment day is not pinned to any day of the month. You get it by entering 0 in the Payment day of the month (0 = no fixed day) field. The due date is then simply the base point plus the credit period of the payment terms.
- Due date: the date on which an invoice must be paid, calculated automatically from the payment day configured and its cycle.
- Credit period: the days contributed by the customer's payment terms (for example 30 days). They are added to the base point before moving to the fixed day.
How the due date is calculated
The due date is worked out in three steps, combining the customer's payment terms with this payment day:
- Base point. According to Calculate due date:
- From the invoice date → it starts from the invoice date.
- From month end → it starts from the last day of the invoice month.
- Credit period. The days from the payment terms are added (for example 30 days).
- Fixed day of the month. If the payment day is other than 0, the resulting date is moved forwards to that day of the month. If that day does not exist in the month (for example day 31 in February), it is adjusted to the last day available.
Example
- Invoice dated 31/05.
- Payment terms: 30 days.
- Payment day: 10, calculate due date From the invoice date.
Calculation:
- Base point = 31/05 (invoice date).
- + 30 days = 30/06.
- Move forwards to day 10 of the month = 10/07.
Due date: 10/07.

Frequently asked questions
Q: How do I create a new payment day?
A: Click the Add button in the list. The Payment day dialogue opens: type the Name, the Payment day of the month (0 = no fixed day) and choose the cycle in Calculate due date. Click Save.
Q: What is the "Payment day of the month (0 = no fixed day)" field for?
A: It is the specific day of the month on which payment falls due (for example 10 = always the 10th). If you enter 0, there is no fixed day: the due date is simply the base point plus the credit period of the payment terms, without moving to any day.
Q: What is the difference between "From the invoice date" and "From month end"?
A: It is the option in the Calculate due date field. From the invoice date counts the days from the exact date of the invoice. From month end first jumps to the last day of the invoice month and counts the days of the payment terms from there. Useful for customers who are invoiced throughout the month and pay the following month.
Q: My customer pays on the 5th of each month. How do I set that up?
A: Click Add, set Name = "Day 5" and Payment day of the month (0 = no fixed day) = 5. Save. Then assign it on the customer record.
Q: I do not want a fixed day, I just want it to fall due according to the payment terms. How do I do that?
A: Set Payment day of the month (0 = no fixed day) = 0. The due date will simply be the base point plus the credit period of the payment terms, without moving to any particular day.
Q: My customer pays "30 days, end of month, on the 10th". How do I set that up?
A: Payment terms = 30 days; payment day = "Day 10" with Calculate due date = From month end.
Q: What if the fixed day does not exist in that month (for example day 31 in February)?
A: The system adjusts it automatically to the last day available in the month.
Q: How do I copy a payment day I already have?
A: On the payment day row, open the context menu and click Duplicate. A copy is created that you can rename and adjust.
Q: How do I delete a payment day?
A: On the payment day row, open the context menu and click Delete. You will be asked to confirm before it is deleted.
Q: Can I import or export my payment days?
A: Yes. Click Import / Export to open the dialogue that imports or exports the records in CSV/JSON format.
Q: Why is the "Save" button disabled?
A: Save is only enabled if the form is valid (Name filled in) and you have made a change. If you have not touched anything, or the Name is missing, it stays disabled.
Q: Can I have two payment days in a month (for example 5 and 20)?
A: The catalogue is designed for a single day per entry. If you need two, create two entries with Add and assign whichever applies on the individual document.
