Hi All, Is there a way to setup payment terms for customers that are not driven from a standard date when invoice was created but from a different field (a travel date in our case)?

Yes with workflow

Thank you for your answer. Would it be - set field value Due Date? And do I need to use formula or condition?

Yes set field value Due date = travel date

Thank youu :) How do I set a different conditions? E.g. Due date 21 days prior to travel date for a specific business line (a custom field we have)? I was thinking if I created a saved search would that be helpful?

Yes you can set à condition in your set field value If business line is Sales ( it’s a example)
