A license is used by a G Suite user who is assigned a Signature template, and therefore you do not need to license users who will not have their Signatures managed by Ancoris Signatures. 


Use our licensing tool at https://www.ancoris.com/products/ancoris-gmail-signatures/ to work out what your annual price would be. 


Ancoris Signatures is sold in packs of 25 annual licences, and if you purchase additional licenses during your annual subscription, the additional licenses pricing will be pro-rated to your existing expiry date.
