# 17. Master Business Configuration

[Master Business Configuration](https://autosoftware.company/configuration_master.php?gid=1) is the single place your shop's own details and working rules are set, and most other screens in ARM read their defaults from here. Settings are grouped into Store Information, New Client/Inactive Settings, Sales Tax Rates, Invoice Entry Settings, Employee Settings, Email/SMS Settings, Reward Functionality and Legal Language/Disclaimers. Every group is a list of Configuration Title and Configuration Value rows with an edit icon in the Action column.
