To be able to get freelance data entry skills, I have experience with various software programs. Some of the most common programs used in data entry are:
Microsoft Word files
Excel
PowerPoint
Access
Open Office
A basic familiarity with what type of software each is and how it is used can be helpful in describing your skills to prospective employers.
You also need a reliable Internet connection to allow the projects to be sent back and forth between you and the employer. You need to have a permanent email address that is also reliable. The employer must be able to communicate about current projects, offer new ones and must be able to receive your projects in a timely manner. With a reliable computer, fast typing skills and a high level of accuracy, you can pick up as many freelance data entry jobs as you choose.
