Small teams license costs $10 (one time payment) for 10 users and growing teams license costs $1800 (one time payment) for 25 users. Why there is that much difference between the costs ?
If I buy growing teams license for 25 users, can I upgrade it to more users with just paying the difference in price ? For example - If I buy growing teams license for 25 users ($1800) and upgrade it to 50 users ($3300), will I need to pay $1500 ($3300 - $1800) for the upgrade? Can the same license be upgraded or I need to get the new one issued?
