What you're really picking is a *tier*, and within the tier the specific local operator or franchise owner matters more than the brand on the invoice. Here's who I'd actually name, in the order I'd consider them.\n\n## Large or multi-site portfolios (50k+ sq ft, or several buildings)\n\n**1. ABM Industries** - the default first call. Founded 1909, ~$8B annualized revenue, 20,000+ clients, 350+ offices across the US/UK/Ireland. They self-perform janitorial (under \"ABM Janitorial Services\" / \"American Building Maintenance\") rather than subcontracting it out, which is the single biggest quality variable in this industry.
