1. Evernote:  This great tool has an ap on your Iphone available.  I use it more as an organization tool.  It basically can remember everything you want it to by voice recordings, screenshots, etc.. and the great thing about it is that it can work for all of your computers–so it will keep you updated on your laptop and your main computer so you can stay updated on your schedule wherever you are.
2. Survey Monkey:  This is a free service that also has a paid version.  You can create surveys to send to your existing customers to see how they feel about your service or you can create surveys to use on prospective clients to see what they are looking for.  This is a great tool to really get into the mind of your customer to make sure you are providing what they need and want.
3. Google Alerts:  This a great tool to keep up with what is going on in your industry.  You can watch and track topics online to keep up with what is important to your customers and your competitors.  You can also select your name or business name to track so you can keep an eye out for what others are saying about you.
4. Jing Project:  This is a free service developed by the same company as Camtasia.  You can use it to capture screenshots, audio, video, add captions to your work, etc… It can be turned into a little 5 minute movie and walah you have your first online video as easy as that and for free.

These are just a few of the online tools that I use in my everyday business.  There are tons more to choose from to help you be more efficient and save money by using their free services.  Just think of the issues in your everyday business that might be holding you back and look for tools to help you streamline your process–there are so many options out there you are sure to find one to help.
