  • Key Takeaway: The primary challenge in vending is securing high-traffic locations, which is often achieved by pop-in visits to properties with front desk staff and targeting locations with 100+ units or employees.
  • Summary: While Amazon sells machines, going directly to manufacturers is better for financing options. Successful pitches involve asking property managers if they want to provide ‘modern amenities’ and qualifying locations based on foot traffic (e.g., 400 residents in 200 units). Modern machines with card readers capture 80% of sales, replacing outdated, unstocked units.
