Example: Chaim Pikarski continually seeks out and capitalizes on opportunity gaps. He and his team scours product listings all over the internet and thoroughly reads the reviews section. They are continually on the lookout for deficiencies and feature gaps that buyers post. With this information in hand, he sources a manufacturer in and makes his own, better version of the original product.
There are also shopping apps like ibotta, MobiSave, and checkout 21 that give you money back for shopping. And the Walmart app has a savings catcher feature where you take a picture of the barcode or upc at the bottom of your receipt and they search all surrounding store and if a lower price is found they give you the difference back. I have made about 50 bucks total from this app and 20-30 from things like ibotta.
Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs.
Advertising. You’ll need to get the word out about your sewing business, and one of the best places to start is with your friends and neighbors. Make sure they are all aware of your services and are willing to pass around your business cards. In addition, you should put up fliers in local fabric stores and get to know the employees so that if someone asks, they’ll be able to refer you. Any business needs a website, and yours will be no exception; you can put up a simple one that outlines what you do, and tells the reader what kinds of prices to expect. Finally, by joining organizations like the American Sewing Guild, you’ll be able to stay in touch with others who are doing the same thing as you.
