Volare Suite

White label private aviation catering platform

A full multi tenant SaaS for private aviation catering companies. Every catering business gets its own branded, white label workspace (custom subdomain or domain, logo and accent color) on one shared codebase with strict database level tenant isolation.

Flight departments order through a branded portal: choose the kitchen location, browse its menu, flag allergens per item, pin an exact delivery point on a map and track the order live from kitchen to aircraft. Kitchen managers run production stations and print labels, dispatchers auto assign drivers on optimized routes, and owners manage users, pricing, invoicing, payroll and expenses. A platform console handles tenant onboarding, plans, MRR and a two way email inbox.
