Communication is very vital to business and there are different online tools to choose from. Some are free and others are ridiculously pricey! In case you’re not sure what to use, I found this very interesting article from Small Business Computing about the different software-as-a-service (SaaS) tools that help enable online collaboration.
Audio and video conferencing services — Skype is the most familiar, but there are many — use the Internet to bridge participants together and carry voice and video.
Web conferencing solutions such as Cisco’s WebEx and Citrix GoToMeeting allow participants to join an online meeting to view presentations or collaborate on computer-based work. Some also allow you to conduct online seminars, or webinars.
E-mail collaboration solutions such as Google’s Gmail let distributed work forces use the same online mail service, and may offer presence and instant messaging as well.
Document sharing tools — Google with its Google Apps, for example — provide a central online repository for documents, with mechanisms for determining who can view and/or edit them. Document creation tools allow groups to mark up or — rarer — directly edit documents online during a meeting.
