If you're a regular reader of the blog you know that we here at Grasshopper are big proponents of working in a virtual office. It can be a smart and cost-efficient way to start a business and we've given tips on everything from “Setting up your virtual office” to “Balancing life in a virtual office”. Well we've got one more.

With over 300,000 apps available in 2010 and more being created every day, there are a number of really great apps...especially for those working in a virtual office! So here we go:

Chat

At Grasshopper Group, we have team members in Boston, Austin, San Francisco, North Carolina, Oregon and even Brazil. It's important that everyone is on the same page and we're able to reach one another when necessary. A couple of apps we keep handy for chat:

Files & Collaboration

Have you ever spent hours putting together a doc only to find that you saved it on a different computer? Or asked for feedback from someone and were forced to email it back and forth, forgetting which doc was the right one? Me too. The great thing about these apps is that they let you store files & collaborate with others from ANYWHERE.

To do Lists/Notes

When you're building a business there are a million things you want and need to do. If you're like me, you need lists and notes and are constantly reminding yourself of new things. Whether you're on the go, or even just sitting in front of the TV, you need a way to quickly jot things down. Well there's an app for that:

Time Tracking

When are you really into what you are doing, it’s easy to lose track of time. It’s even easier when are you aren’t in an office. Whether you are a consultant tracking your hours or an entrepreneur just trying to figure out how long things are taking, it’s nice to be able to track that time. There are a few good time tracking apps that can help:

Passwords

How many passwords do you have? Do you even know? Personally, I have two spreadsheets (one work, one personal) each containing multiple tabs. Wouldn’t it be easier if I had them all in one place, and it was handy? Here are a couple password keeping apps:

Travel

When you have several teammates working in a virtual office, it can be hard to keep track of one another, especially if you are travelling. When does their flight land? What time are they coming back? With all the travel apps coming out, knowing these things is much easier.

With all of the new apps on the market and the new ones on the way, working in a virtual office has never been easier. Which apps are your must haves?
