The basic Business package, priced at £429, lets you hold meetings with up to 15 participants and lets you run meetings and control remote computers from one PC. It's also backward compatible, so TeamViewer 9 can control systems running version 3 or later. Although a new version of TeamViewer is released every year, your existing version will keep working and you'll still be able to download the client software from TeamViewer.

Many web conferencing and remote desktop providers sell monthly subscriptions for each client PC, but you only pay once for TeamViewer 9, with the number of client systems you can connect to determine by which of three editions you buy.

It’s a shame other participants can’t use the whiteboard tools, too. You can also record your session for future reference.

Other handy features include a whiteboard tool that lets the presenter temporarily draw and highlight objects on the shared screen, a basic text chat box, a file sharing box to distribute materials and the My Video tool, which lets you display the video feed from a connected USB camera. You can set up a conference call using TeamViewer’s built-in VoIP capabilities or a 7p per minute dial-in number. They'll be able to see and hear whatever content you're displaying, whether it's a new application or a PowerPoint presentation. When you invite participants to your presentation, your active screen will appear on their display. TeamViewer's built-in communication features also make it an excellent remote conferencing tool.
