These days, most proposals don’t lose to the competition - they lose to indecision.
A Harvard Business Review study analysing over 2.5 million B2B sales conversations found that 40% to 60% of deals end in no decision at all. Not because buyers are satisfied with the status quo - but because they’re afraid of getting the decision wrong.
When proposals fail, it’s often because buyers are overwhelmed by choices, unsure whether the offer will deliver results, or confused about which package to pick. The more uncertain they feel, the more likely they are to stall - and the deal quietly dies.
And that missed deal isn’t just a one-time loss. The probability of selling to a new customer is only 5–20%, but once you’ve won the first deal, that number jumps to 60–70%. So every proposal you get right is more than a win - it’s the start of a long-term revenue opportunity.
To understand what actually drives those wins, we analyzed over 1.3 million real proposal sessions sent through Storydoc. We looked at which proposals were opened, which were read, and which got the signature.
Here’s what we found.
