Why 70% of Sent Proposals Stall in Executive Review

Most service providers and agencies lose deals at the proposal stage for two reasons: (1) Excessive length filled with generic company history nobody reads, and (2) Vague deliverables that leave the client fearing budget overruns.

An executive wants to know three things in 3 minutes: What problem are you solving? What exact deliverables will you hand over by what date? How much does it cost, and what are the payment milestones?
