Databases can be much more than just managing your contacts. A few common uses for databases are:

• Contact Management
  Keep up to date information of all your potential clients, your existing client accounts and suppliers
• Stock control and pricing
  Your web site can display to your customers a price of an item and if it is in stock for immediate dispatch.
• Invoicing
  When a client orders an item, an invoice is created automatically, the prices are inserted along with any discount structure that applies to that client, then the item is removed from stock
