With nearly 100,000 different custom extensions both free and paid available in Google Chrome's marketplace, there's a huge opportunity for creating a useful extension for people to use while browsing the web as a low effort business idea. One of my favorite Chrome extensions, Yet Another Mail Merge, which enables you to send bulk customized emails from within Gmail, gives you 50 free credits to send emails and gives you the chance to upgrade to a paid account to unlock more sending—a great upsell for the people who are getting value from the extension. Even free Chrome extensions like SVRF Tabs by SVRF, which replaces your new tab with stunning VR and 360º images, have the potential to bring in new users and eventually drive revenue for the startup's core business. Another fun example from a friend of mine, Kathleen Garvin, is Hide images with NOPE, a Chrome extension that hides images on the web pages you're browsing—to help eliminate distractions and keep you from seeing images (like those of certain politicians) that you may want to hide. This side business idea is particularly great because it also allows you to showcase your development skills—which can be put to work as an adjacent side business idea on a freelance basis alongside the Chrome extensions you launch.
Selling real flowers is where things can get tough. Many people already have a green thumb, and often they already supply flowers to friends and family. You will need to figure out which flowers will survive the shipping process, and decide how great of a distance you are willing to deliver across. Again, clear, attention-grabbing images will be key for successful selling.
Tutoring pays quite well, and many clients will refer you to others, especially if their son or daughter shows significant improvement or finishes a class with a good grade. People want to know what they are paying for, so advertise your skills by having previous clients give testimonials and providing information on your own educational background.
The easiest activities to eliminate will be the ones in which you have the least amount of involvement or responsibility. You may want to keep activities for which you have a significant amount of involvement, or which are relatively prestigious positions for you to have. For example, you might want to eliminate a community organization if you only participate sporadically, but keep the group in which you've just been elected treasurer.
You want to gain business, but investing in large marketing efforts could have two negative effects: You could waste a lot of money on a campaign that produced very little business or it could produce so much business that you don't have the time to handle all of the orders. Instead, focus on word-of-mouth advertising and let the business grow debt free.
It’s not the sort of side business idea that’s covered in glory, but someone needs to make sure all the numbers add up at the end of the year. Every business and most individuals need someone with the domain expertise to help prepare tax returns, especially time or resource-strapped small business owners. Majo Jacinto in his Udemy course provides an in-depth foundational understanding of how to prepare tax returns (and stay current with ever-changing laws) that'll certify you with tax prep skills in as little as a few hours of training and practice. Then once tax season rolls around you'll be able to charge an average of $229 per return as a freelance tax preparer with this side business idea, according to CNBC.
If you love to create art of any kind, you could be making a little side-income with your talent. Custom, one-of-a-kind paintings are popular decorations, and many people are willing to pay for unique works. This side business idea is great, because it takes something you love (and would probably be doing anyway) and turns it into a source of income.
