One additional license, Forms Pro Addl Responses, costs $100 and allows you to receive 2,000 responses per month at a tenant level. This means that everyone in the tenant can use a total of 2,000 responses. You can purchase the licenses in bundles of $100 as required. So, if you purchase one Forms Pro Addl Responses license (for a bill amount of $1,200), you will get 24,000 responses (12 × 2,000) annually. If you purchase two licenses of $100 each per month for a year (for a bill amount of $2,400), you will get 48,000 responses (12 × 4,000) annually.
