License is either single entity or multiple entities. For single entity, you may use the chart for one organization's SOC build. For MSSPs or consulting firms, a minimum payment must be made per organization for each use.
Pricing is sliding scale. Minimum of $25, maximum of $5,000. It is difficult to specify the appropriate price because organizations vary substantially in how they will use this. I prefer to have the information available to organizations who need it. You can pay the minimum ($25) and if it provided substantial value, pay more later.
Note, purchase of the chart does not entitle the purchaser to consulting regarding use of the chart.
