1. A method comprising: causing a computing system to provide an indication to a first sales development representative (SDR) of a first preliminary sales lead assigned to the first SDR, wherein the first preliminary sales lead represents an individual or organization with an expressed interest in purchasing one or more items from the sales organization; receiving information about the first preliminary sales lead, wherein the information is information gathered by the first SDR; causing the computing system to assess whether the information satisfies a first set of predefined criteria, wherein the predefined criteria comprise criteria for assessing a potential value to the sales organization of the first preliminary sales lead; receiving a qualifying input from the first SDR at the computing system; in response to receiving the qualifying input, causing the computing system to create a first qualified sales lead corresponding to the first preliminary sales lead; providing an indication of the first qualified sales lead to a first sales representative (SR) via the computing system, for attempted conversion to a sales opportunity, wherein the first SR is distinct from the first SDR; causing the computing system to determine whether a disqualification input has been received, wherein the disqualification input indicates that the first SR has determined that the qualifying of the first qualified sales lead was incorrect; receiving at the computing system input from the first SR indicating a reason for the determination, if the disqualification input has been received; causing the computing system to create an indication that the first qualified sales input is no longer qualified, if the disqualification input has been received; providing feedback to one or more users within the sales organization, other than the first SR, via the computing system, if the disqualification input has been received, wherein the feedback comprises a notification that the first qualified sales input is no longer qualified, and the reason for the determination, the computing system provides a first graphical user interface to the first SDR and a second graphical user interface to the first SR, the causing the computing system to provide the indication to the first SDR of the first preliminary sales lead comprises displaying the indication to the first SDR, using the first graphical interface, the providing the indication of the first qualified sales lead to the first SR comprises displaying the indications to the first SR, using the second graphical interface, the receiving the qualifying input from the first SDR occurs in response to the first SDR selecting from among qualifying controls displayed on the first graphical user interface, and the disqualification input was received in response to the first SR selecting from among rejection controls displayed on the second graphical user interface.
