You need not pay for the rent to get someplace for selling your products, or better, if you are selling downloadable stuff (ie. Software, ebooks, music, documents, video.etc) then there would be no shipping cost. And you can capture both local and international market at the same time. Moreover, the online selling can be continuously and truly operated 24/7―it will never happen that you may lose any order because of the limited business hours.
However, before you start your business online, there is something you need pay attention to:
- Nobody would know your existence if you cannot win your website enough exposure on the internet. This means you must do a lot of work to ensure that your website would not be invisible among the sea of websites. Find your niche market, and make your targeted customers get to know and like your products―you have lots of online and offline work to do, for example, do SEO to attain your website good rankings, post ads in newspapers and other traditional advertising materials.
- You need more efforts to convince your visitors that you are trustworthy. After all, dealing business online is not as safe as face-to-face deal. Therefore you have to provide adequate information to establish your credibility, such as the testimonials from your customers who have used your products, the awards you’ve achieved, the background of you and your products, etc.
- You must have multiple lines where clients can contact you. Clients, local and abroad tends to be demanding in terms of prod inquiry so you must keep up (I sometimes answer text msgs at 4AM!) else, you'll lose the trust and credibility.
If you are sure that you can handle all these, it is very likely that you can make your fortune online, especially if you want to sell your software online (BTW, you can view this article if you do want to sell your software online―the way to promote software online).
