Enterprise SaaS sales deals don’t die randomly — they die predictably at each stage of the funnel. Based on data from 250 enterprise software opportunities, this post breaks down exactly where deals collapse — discovery (35%), qualification (28%), needs assessment (22%), proposal (12%), and contract (3%). For pre-seed and seed-stage CEOs, the brutal truth is that 69% of qualified deals will fail unless you fix your sales process. From poor discovery and budget ghosting to technical misalignment and ROI confusion, every stage has a killer that can be prevented with the right frameworks. This guide gives you practical scripts, qualification gates, and coaching advice to dramatically improve your close rates. If you’re tired of seeing promising demos vanish into thin air, this is the no-BS playbook to stop your pipeline from becoming a graveyard — and start winning enterprise customers.
