What WordPress handles for catering businesses
Menus and packages by event type. Five Star Restaurant Menu builds menu pages with sections and prices; dietary icons are in its premium version.
Event quote requests with numbers and dates. A form plugin such as Contact Form 7 collects the job details; photo uploads and conditional fields depend on the plugin chosen.
Online orders for office and small group catering. The Five Star menu plugin has an add-on for taking food orders on your own site.
Delivery area check. There is no core feature for this, so a suburb or postcode check is built as a small custom block.
