We like to inform our clients of the best tools available for their business. Google Apps certainly falls into that category. You get all the benefits of Google's most popular products, including Gmail, Calendar, Docs, and even Voice, branded for your business. You can get the benefits of a similarly configured Microsoft Exchange setup at a fraction of the cost. If you have less than 10 users, it's even free. If you opt for the paid subscription, they include tools to migrate your existing data, including emails, calendars, and contacts, making it a seamless transition for your users with minimal hassle for administrators.
If you need some professional help setting up Google Apps for your organization, feel free to get in touch and we'll help you get started.
