SalesForce - Free CRM (Customer Relationship Management). Use this online service to keep track of customers and potential sales. We are currently beginning to switch over to this service.

FreeCRM - You can't go wrong with either FreeCRM or SalesForce, We recommend test-driving both to see which you would prefer for long term.

Genbook - This service allows you to place a calendar on your website or be able to give your clients a web page where they can set their own scheduled appointment.

Teleflip - Free email to cell phone service. This is an awesome free product. Receive spam-filtered emails by text message to your cell phone. You will have to pay regular text messaging fees, so you may want to consider reviewing your cell phone company's text messaging plans.

MyWirelessReminder - Maybe you're on the computer right now and want to send a quick text message directly to a friend's mobile phone.  Or, perhaps your organization would like to keep customers, web site visitors and staff abreast of special offers, appointments, upcoming events, breaking news, etc.

FreeConferenceCall.com - No kidding really free. They also offer a premium service. Although we have not set up a conference call with this service ourselves, we have participated in calls and we have no complaints.
