Commercial Janitorial Service
The shortcut: Win 4-6 small office or retail accounts on 12-month contracts. Skip the big buildings — they go to RFP and want a million dollars of insurance you don't have yet.
Industry: Cleaning & Maintenance
Investment level: Low — $2,000-$8,000
Time to launch: 4-8 weeks
Best for: People who don't mind nights and early mornings, and who'd rather close one $1,800/month office contract than chase 30 one-time house cleans. You're a fit if you can pass a background check, drive between buildings after hours, and run a vacuum for 4-hour stretches. What you'll likely make: ~$3-$4K/month after expenses by month 3, and $6-$8K by month 6 if your accounts cluster within a 15-minute drive. Full math in Section 3.
Market Opportunity
The big national chains — ABM, ISS, Aramark, ServiceMaster — own the high end. They won't bid on a 4,000-square-foot dental office or a single Verizon storefront because the contract is too small for their bid team. That gap below them is the opening for a small shop.

- 62,099 firms across 66,471 establishments (2020 Census). Average shop has about 17 employees. The long tail is dominated by shops with fewer than 10 people winning small B2B accounts the giants ignore.

- About 6% of customers will quit each month across the cleaning industry — MaidCentral Professional Cleaning Index. On a 12-month contract that's a quarter of accounts gone in a year. Always be selling.
Target customer: Small-to-mid offices and retail under 25,000 square feet — dental and medical practices, law firms, real-estate offices, single-location retail (boutiques, pet stores), small fitness studios, churches, daycares. Skip Class A office towers (they go to RFP and require $5M-per-occurrence general liability you can't afford yet) and skip warehouses (square-footage rates are brutal).
Why this is a good time to start: A lot of property managers signed cleaning contracts during 2021-2022 at panic-cleaning prices and never renegotiated. When they see their bill is $2,400 for a building that should be $1,400, they put it out for re-bid. You don't need to sell harder — you need to be the obvious cheaper-and-still-good option when the rebid comes around.
