To be honest, making the decision on what to sell is the biggest hurdle we've had to constantly overcome when starting up new online ventures. You have to find something that can be sold online and shipped relatively easy. You have to identify things that are profitable and the market isn't already flooded with. Perhaps the most challenging, but most important, part is finding something to sell that interests you.
You'd be surprised what is sold online these days. People buy and sell animals, cars, houses, furniture, etc... However, we don't recommend jumping right into any of these categories. If you're doing business online for the first time you are going to want to find a product niche that is commonly sought after online and also something that can be shipped in a timely and safe fashion. One thing worth looking into are eGoods. EGoods can include online books, movies, videos, tutorials, etc... These are goods that are delivered to customers electronically and involve the least amount of hassle with deliveries.
The second thing you must do is steer clear of the high-appeal items. These include things like iPhones, laptops, cell phones, cameras, etc... Especially the big name items. This is the most common type of mistake made by beginner retailers. These items are common ground things to society today - everybody is familiar with them and everybody knows that there is a huge demand for these items. However, because of the sheer amount of resellers that have jumped into the market for these products, the prices are driven down to the point where profits are extremely slim. Also, keep in mind that you will be competing against companies such as Best Buy who have tremendous buying power and are buying directly from the manufacturers. It is imperative to identify non-traditional goods that have relatively low competition. Remember, there is a buyer for everything these days. Your marketing costs will be lower, your wholesale prices will be lower, and you can acquire a bigger market share faster.
Last, but definitely not least, find something that interests you. Did anybody ever tell you when you were young to "do something that you love"? The same thing applies when you're looking for things to sell. For most online entrepreneurs, the ultimate goal would be to replace their current income and working for themselves from home. If that comes to fruition one day, you'll be happier and more successful if you're selling something that interests you or that you have a passion for. Another important factor is that you will naturally be more knowledgeable and familiar with items that you have a natural interest or passion for - and that will help your business in a big way.
To conclude, we strongly recommend beginning your online venture by identifying inventory products that are realistic to sell online, not flooded in today's online market, and something you have a natural passion for. If you can find something that meets these criteria you will have much more success with your
