"Passive income" gets thrown around loosely. Real passive income takes work up front and pays you afterward. Here's a grounded map of the options, sorted by how much capital they need.

Low-investment ideas

  • Print-on-demand merchandise
  • Affiliate marketing
  • Self-published e-books
  • Faceless YouTube channels
  • Digital templates and online courses

Higher-investment ideas

  • Rental property and REITs
  • Dividend stocks and bond funds
  • Peer-to-peer lending
  • Vending machines
  • Buying existing websites or royalties

The one people overlook

Merchant-services residuals belong on this list and rarely make it. Once a business is set up on processing, you earn a slice of every sale it makes - month after month, with no inventory and no ceiling. It's the model Cashswipe is built around.
