Proposal Tracking That Builds Confidence and Peace of Mind

It gives me confidence in my own work. When I send a proposal, I'm not left wondering whether it landed in someone's inbox and got ignored. I can see that the client actually opened it, went through it, and spent time with it. That comfort - knowing the effort didn't go to waste - is honestly the biggest thing for me.

Clear proposal engagement signals helping us time follow-ups better

The main thing I get from Sellizer is knowing whether a prospect is still engaged with our offer or not. When I see someone opening the proposal a second or third time, I know the deal is alive, and they're still considering it. It's a simple signal but a useful one - without it, you're just guessing whether to follow up or move on. I also like seeing which sections of the offer get the most attention and which get skipped. We don't always act on it directly, but over time, it gives us a sense of what to refine in our proposal structure and how we present our portfolio.

See What Happens After You Send the Proposal

Sellizer is a sales engagement platform that shows B2B sales teams exactly what happens to their proposals after they're sent. Users see the moment a prospect opens an offer, how long they spent on each page, which sections they revisited, and whether the document was forwarded to other decision-makers - making it instantly clear which deals are alive and worth pursuing, and which have gone cold. Real-time alerts let reps follow up at the peak moment of buyer interest, replacing guesswork with data and helping close more deals. Integrations with leading CRMs - including HubSpot, Pipedrive, Salesforce, Zoho, Monday, Dynamics 365, Raynet, and Firmao - bring proposal activity directly into existing sales workflows.
