Purchase a license to enable all of the features available in QnE Companion. Each license covers a single computer within the licensees household or business. The pricing tier discounts are based on the concept that each additional copy from 2-10 is around $2, from 11-26 it is around $1, and quantities of 27 or more is simply $1.78 each.  For example, to cover a single system, purchase a single license for US$12.95.  To cover five systems, purchase five licenses at US$4.19 each for a total of US$20.95.  Note that the discounts are not cumulative across multiple orders, that is if you purchase one now and another one later, both orders will be US$12.95, not the first one at US$12.95 and the second one at US$7.48.
