Here are 11 passive income ideas to start investing for a complementary source of income

1. Invest in the stock market and receive dividends. It requires having a little starting capital :)

2. Investing in real estate and renting. You don't need any seed money here if you're doing 110% financing at the bank. If your rents are higher than your repayments to the bank, you will make positive cash flow and therefore passive income.

3. Invest in crowd-lending. It's about lending money to a business to grow. The company pays you back your money with interest. You can expect 8–10% profitability.

4. Create a blog / website and advertise on it (eg via Google Adsense).

5. Publish videos on YouTube and make money from advertising (you know those annoying ads that you can't get ahead of the video)

6. Create a profile on Patreon (or Tipeee) to ask your community to give you a small amount each month (from 1 €) to support you. You still have to have a community :)

7. Write a book or ebook that you can sell directly on Amazon.

8. Create and sell training courses. You can sell them directly to your community if you have one or sell them on mainstream training platforms (eg Udemy)

9. Sell your photos. For example, you can sell them on iStock. If you know a bit about photography, you can, for example, suggest that those around you do a free photo shoot in exchange for their permission to resell their photos online.

10. Affiliate: This is about recommending someone else's products and earning a commission if a sale occurs. You can do this on your website, on your YouTube channel, on Instagram / Facebook, by email, etc. etc.

11. Sell your own physical products. You can do dropshipping (ship products from producer to consumer) or create your own products.
