The state of Texas requires licensing of any company in order to sell and / or install security based products, specifically alarms.  Any company receiving a license must be managed by an eligible individual.  Eligibility is based on criminal record and work experience.  In order to be eligible for a license, a manager must have relevant documented work history for at least two years related to the category applied for prior to application.  All other owners and principles of the company must also submit an application as well, however there can only be one designated manager.  If an individual representing a company does not have the requirements for a manager license on their own, the company can designate a different manager in order to obtain a license, however a manager cannot be responsible for more than three companies or two schools.  Work experience must be continuous and documented.  Background checks and fingerprint submission is required.  All individuals selling or installing security alarms must also be licensed individually and their license can transfer from one company to the next.
