It’s not very engaging, or mentally stimulating, but taking online surveys through companies like Survey Junkie do pay out (a little), believe it or not. Even if the payouts come in the form of Amazon gift cards, sites like Swagbucks can pay well. Just don't expect to make bank with this side business idea—I recommend combining it with another source of side income from this list of my best business ideas, and turning to surveys in your downtime when you need a little extra income.
Similar to selling on Amazon, eBay is a place to make money selling just about anything you can think of as a side business idea, with the added excitement of using the auction selling model to sometimes get way more than you expected for that antique baseball card you picked up at a local street fair. To turn your eBay selling into a legitimate business idea, look for opportunities where you can buy in-demand products at a discount—and later sell them for a profit. Eventually, you can even take the lessons learned from your eBay store and build a full on blog or eCommerce business like what the team over at Gear Hungry has done.
Ask your parents if they'll pay you for doing more chores. You're probably already expected to do chores around the house and help out your family for free. If you need a little extra pocket change, however, ask your parents if there's something else you can do for a small fee. For instance, maybe your mom really hates folding laundry and would be willing to pay $5 a week for you to do it instead. Whatever it is, let your parents know you're willing to take on more work for a bit of allowance.
Not only is Airbnb a great way to make money by renting out your spare bedroom or living room couch as a legitimate home-based business idea, but you also have the benefit of meeting new people and making new friends if that's your kind of thing. You can even rent out an entirely new apartment just to manage as an Airbnb side business idea, but don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, you can take this business idea to the next level by offering your guests add-on and personalized experiences for an extra charge. Take Lauren Gheysens' Airbnb-based side business idea, Royal Day Out in London, England for example—where she gives visiting tourists a local's only tour of the city, complete with bespoke 18th century costumes.
