Yes, if you work with multiple company entities in Teamleader, you can set a default company entity. 


To do this, follow these steps:


  1. Go to Settings > Company information
  2. Click on the pencil next to the company entity you'd like to set as default company entity
  3. Click on Edit next to "Filling out your company's info (name, address, email,..)
  4. In the General information, tick the box next to 'Default company entity'

This will cause this company entity to be the default one, and therefore the one used by default when creating invoices, quotations or when using a signature when sending an email. Remember that even if this is marked as default, you can continue to manually select the other company entities when necessary.
