Anyone can sell goods on Amazon, provided you have products to sell (or buy low, then resell). If you’re the type to hit all the local garage sales each weekend, there’s all sorts of valuable things that can be resold online as a side business idea. If you want to step your Amazon selling game up, check out this detailed guide to Amazon and eBay retail arbitrage on Entrepreneur featuring an interview with Julie Becker and several drop-shippers who've grown this home based business idea from side business idea into a lucrative money-maker.
78. Understand your own work habits and what tools will work best for you. “Get an egg timer or a digital stopwatch with a countdown function,” advises Laurence J. Stybel, founding partner and president of Stybel Peabody Lincolnshire. “Decide on the chunk of time that you are most productive. For example, I can be productive for 45 minutes at a time. After that, the law of diminishing returns starts to apply.”

In many parts of the country, this business tends to be seasonal, but you can find ways around that. Rent a storage unit and offer to store people's bicycles over the winter after you do a tune-up and any needed repairs on them. If you want to cater to the Lance Armstrong wannabes, you can have business all year round. These road race riders are training through snow, sleet and dark of night. Some of them work on their own bicycles, but many of them don't, so you can get their business all year. And if you keep Saturday shop hours, you can be sure you will have a group of enthusiasts coming by to talk all things cycling.
We're all guilty of spending too much time on Facebook, Twitter, or Pinterest sometimes, so why not get paid to put your expertise to work as a side business idea? Lots of companies, especially startups or those in retail and travel—even influencers have heavy social media presences and are constantly in need of people to help build their brands online. You can find these types of opportunities on sites like Flexjobs and CareerBuilder and most employers on these websites are conditioned to working with people who operate these services as their side business idea. Over time as you grow in your ability to leverage various social channels, you can add more service offerings like running high-return Facebook Ad campaigns or hosting lucrative sweepstakes competitions for the brands you want to work with.
Start with a very good checkout flow / payment gateway right from the start. I’ve spent too much time thinking I could whack some checkout together with PayPal and a (typical Dutch) bank payment system, but ended up with a lot of coding and hacking into WordPress to make it all happen. Actually, the right checkout still hasn’t been implemented #@!^&*^
But it’s also easier for consumers to compare similar products, which makes your ability to differentiate yourself more important. For instance, if you decide to use Etsy to sell handcrafted cutting boards, when a potential customer searches for cutting boards on the site, they’ll wade through potentially hundreds or thousands of relatively similar listings.
Best of all, unlike a brick-and-mortar business, you don’t need a lot of startup capital. In fact, you can get many internet businesses up and running with no money at all because so many free services facilitate the possibility. For example, you can set up a website or blog for free using WordPress. Or you can leverage a third-party site like Amazon or eBay to sell goods. You use their selling platform in exchange for giving them a cut of your sales.

Check your local authority’s zoning and permit regulations pertaining to home-based businesses. These can vary widely from area to area. Most are concerned how your business will impact your neighborhood such as customer parking or shipping traffic. Check, too, with state or federal agencies for required licenses or requirements your business may need.
Driving for one of the two globally expanding app-centric taxi alternative services, Uber or Lyft can still be a fairly lucrative way to earn money as a side business idea on nights and weekends—working only when you want. But before you dive head first into this side business idea, do your homework and calculate the costs of extra gas, mileage, tires, wear & tear and usage on your vehicle—it's not a guaranteed business idea that'll turn a huge profit every weekend.
