Mirror a field from Accounts within a Contact

Mirror a field from Accounts within a Contact

Hi all,

We use a custom field to show the stage of every Accounts. Now, we'd like to show this field additionally within Contacts.

However, it needs to be "dynamic". So, when the value of the field changes within the Account, it also needs to change for all contacts related to that account.

How is this possible?

Thx & Greetings
