What are the tasks that you're looking for?
Most of our business comes from our websites. Our reservations calendar is automated and run from the web pages. Our demo requests are handled on our website. Customer information forms are on our website.
Business-wise, we run everything off of three apps - our web application, Outlook and Quickbooks.
I just started programming a web visitor tracking application, because after checking everything out there, I couldn't find anything that really told the story in a way that would help us make our website more efficient and get more sales. So, I would add web-tracking to the applications listed above.
