Karbon Questions

Having trouble seeing your documents?

Try logging out of Karbon and logging back in. This resolves most document visibility issues. If the problem continues, reach out and we will get it sorted.


Received your first Karbon invite?

You will need to create an account to get started. Once your account is set up, you can link any additional entities (such as a corporation or other business) directly to your existing login so everything stays in one place.


Have more than one entity on your account?

Click on your current entity name at the top of your Karbon account and a dropdown menu will appear showing all entities linked to your profile. From there you can switch between them easily.
