Hello Antonia Maria Romero Jurado,

Odoo Accounting: The Odoo Accounting app allows you to track expenses and set due dates. You can create journal entries for each expense, and set the due date for when the expense needs to be paid.

Third-Party Apps: There are apps available on the Odoo Apps Store that might meet your needs. For example, the ‘Expenses Tracker’ app allows you to track expenses and set due dates.

thanks you!!
