The map below is a simple Google Maps API - based application (script) plugged directly into my Client Billing & Invoicing System. It pulls clients' coordinates (latitude and longitude) stored in database and automatically plots them out on the map. So when a new clients gets added to the database, he is already shown below automatically. - Just wanted to note, they are long-term clients so the total number of clients is not very big but enough to keep a single web developer busy. I could not accept new customers for a couple of past years because of being too busy with existing clients.
