Great to see you in the Community @martacalvinho! Thank you for your question. Indeed this type of notification is not currently possible within Bynder. Currently, you can see how many seats you have left in the permissions profiles. I am happy to share this with product as a feature request on your behalf.

Hey @martacalvinho, 

There are two ways that I often check the user license count.

1. As @Ryanne Perry mentioned, you can go to Users & Rights > Permission Management. The numbers will appear next to each main permission category (Light/Moderate/Heavy users)
2. The Cockpit gives a quick view as well. I like this method because it shows both the number and a status bar. Advanced Rights > Cockpit

I would love a feature that allows admins to choose a threshold for any criteria that is limited (i,e, Users/Storage), once that threshold is breached, notifications go out to admins and CSMs. 

Thank you @KevinMurphy! Indeed, I can see your point. Sending this over as an insight
