Your own alternative to Salesforce Sales Programs
Manages sales incentive programs and partner or rep campaigns.
Salesforce Sales Programs: US$100 per user per month, billed annually. 50 users: US$60,000 a year, excluding Sales Cloud, as a pricing scenario.
We have not found an open-source project that does what Salesforce Sales Programs does well enough to list. That usually means the software is specialised, and the quickest way off it is your own version.
