General Company Settings
Use General Company Settings to specify your company's name and address and other general information, such as a default phone format. If your enterprise uses multiple companies, you must specify General Company Settings for each company.
Name and address information displays at the top of screens, on your invoices (if you use Billing), and in the headings of reports. You can also enable the Payroll application.
If you use multiple currencies, you see an additional Currency tab, where you assign currencies to your company or companies.
