Contrary to popular notice, selling products online is not that difficult. It is not exactly easy but it is not too daunting too.

There are many things that you can sell. As long as it is software (legal), you can sell it.

Some of the files that you can sell are:

1. Software programs

2. E-books

3. Stock photographs

4. Templates

5. 3D digital models

6. 2D graphic images

Of the list of files above, e-book is the easiest to create. It is also one of the most sell-able. Creating an e-book will not cost you any thing apart from the time and effort. The most common format for e-books is PDF. The best free software for creating PDF ebooks is Open Office. Open Office can easily rival the commercial Microsoft Office in terms of functions and features.

Once you have finished writing the e-book in Open Office, you simply need to export the document as a PDF file. The appeal of e-book lies in the fact that it is easily accessible and does not require physical space when compared to physical books. This reason alone make them quite easy to sell. Many people are after information only and are not so concerned about whether the product is physical or not.

Beside, e-book the other very easy to create product is stock photo images. You will need a good digital camera and an image editing program to create the photos. If you do not want to buy commercial image editing software, you can download free ones. The best free image editor is Gimp.

I can go on rambling, but I think I will stop here.

The bottom line is this: It is not that difficult to create and sell your own digital products. And there is no harm in making some extra recurring incomes from these sales.
