Once the Catering module is enabled, a Catering group appears in the left admin menu (labeled Events instead if you only have the Proposals module, without Catering). Inside that group you'll see up to three separate menus:

• Catering — Dashboard and Catering Menu (Catering Menu only appears if "Catering: Allow Online Ordering" is turned on in Client Config, which it is by default).
• Proposals & Invoices — this is where Catering Settings lives (it shows here even if you only have the Catering module and not Proposals). If Proposals is also on, this same menu adds Events, Proposals View Builder, and Calendar; Calendar also shows if you have the Venues module.
• Reports — every catering report, plus a Commission Report and Account Receivable Report when Proposals is on.
