For decades, B2B sales has run on guesswork. You send the proposal. Days pass. You wonder if they’ve opened it. You craft a follow-up email that walks a tightrope between “checking in” and “annoying.” You time it by feel. Sometimes the deal lands; more often, it goes quiet and you never quite know why.
The strange thing is that most of what you’d want to know is already happening — you just can’t see it. When a client opens your proposal, scrolls through it, lingers on the pricing, comes back the next morning with their CFO, exits without reaching the end — every one of those moments is a signal.
“The problem isn’t that the signals don’t exist. It’s that PDFs don’t transmit them.”
Move the proposal to a trackable, interactive page and the picture changes. The most basic signal is whether the proposal has been opened at all — that alone ends the “did they get it?” loop. But the more interesting number is revisits: a single open is polite, three or four opens over two days, especially from different devices, is a deal being actively shopped. That’s when the deal is being decided. It’s also exactly the moment when most sales teams either fall silent or send a generic “just checking in” email — because they’re guessing.
