General Specifications:
Security:
•  Program access is controlled by assigning user names and passwords.
•  A log is generated keeping a record of names and times users logged on to the program.
•  Different levels of security can be assigned to individual users to allow the user access to fan selection only or to both selection and pricing.
Project Management:
•  The program allows users to generate and save quotations.
•  Individual users have access to only his/her saved selections. The fan manufacturer has access to all saved quotations giving full transparency to the outside sales activity.
•  Saved quotations can be converted to electronic sales orders without re-entering any data. Sales orders are transmitted to the company in real time. This reduces the sales rep's work load, saves processing time and reduces errors.
