Just as programs like Quicken and Money centralize all your financial information and tasks, auction management tools create a computer "headquarters" for all of your online auction activity. Think of these programs as a dashboard of your common eBay tasks. Using them, you can automate the process for listing items and you can post items in groups. You can even set the program so that it lists the items on eBay while you are at your day job. You can modify photos and store them for easy access online. You can manage your inventory by accurately tracking what's sold and what isn't. You can calculate eBay fees before you post an item for auction. And you can integrate your inventory and sales information with financial software like Quickbooks or with spreadsheet software such as Excel.
