Hello,

This type of payment term (30 days + restricted payment dates like 10th and 20th) is not fully supported out-of-the-box in Odoo.

Odoo allows you to define:

• Fixed delays (e.g., 30 days), and

• Specific days of the month (e.g., 10th or 20th)

However, combining both conditions (i.e., “30 days and then the next 10th or 20th”) requires either:

• A custom development, or

• A manual adjustment / workaround using existing payment terms

A common approach is to create payment terms based on fixed days (10th/20th) and adjust depending on the invoice date, but this won’t be fully automated without customization.

Hope this works for you! Feel free to reach out for further discussion.
