Abstract: Customized sales software for consolidating, organizing and integrating data and process flow in a manner especially suited for sales operations. The customized sales software is customized to represent the user company's business process and integrates the user company's applications and data but does not change the user company's existing applications or databases. The sales software is designed in layers to enable seamless integration of legacy systems and external data sources, without requiring change to them, while at the same time enabling the introduction of new interfaces, transactions and processes. Integration with legacy systems and external data sources is possible at different layers within the software and may or may not utilize existing legacy system applications and processes. Generally speaking, integration with legacy systems and data sources may be either one or two way or in real time, depending on the requirements of a particular business process.
