Conga

Conga (Conga Composer & CPQ) is an absolutely terrifying, heavily entrenched leviathan that mathematically dominates the "Salesforce Native Document Generation" market. It doesn't just create proposals; it mathematically engineers highly complex, heavily regulated contracts directly out of Salesforce data. It is the absolute weapon of choice for massive enterprises running exclusively on Salesforce who demand that every single data point in a 50-page legal contract is mathematically pulled perfectly from the CRM.
