English
Papermark shares a document by link and shows who opened it. Sellizer runs the proposal further: an SMS on the first open, a heatmap and a session recording, plus automatic follow-ups.
Start freeBoth send a document as a link and show who opened it. The difference is whether sharing the file is enough, or you want to take the proposal all the way to the client's decision.
Open-source code you can host yourself, password-protected links, NDA and data rooms. Open alerts arrive by email.
A text message on first open, heatmaps and session replays help you pick the moment and the topic. Follow-ups go out on their own.
Share documents that need an NDA and a data room in Papermark. Send client proposals through Sellizer and know when to call.

Sellizer made it possible for us to increase the pace of customer acquisition by 300% last year thanks to additional knowledge of how customers perceive our proposals. I strongly recommend it to anyone who wants to be more efficient in such a fast-changing business and new technologies environment!
Maciej Zagórowski
CEO Fabryka e-biznesu
Thanks to Sellizer, I know which parts of my proposals are the most interesting for my customers - it gives me great basis to start a valuable conversation. I can also contact with clients in the best time - when they have my proposal right in front of them. Such combination made it so much easier for me to sell projects.
Damian Rams
Digital Analytics Consultant, DamianRams.pl
We like clever solutions. Just like in Sellizer, we believe that the time of contact with the customer really makes a big difference, so we decided to integrate our tools. Thus, Sellizer user gets a SMS message about the opening of the proposal and statistics and recipients of their proposals can ask for contact via Callpage widget. Awesome!
Sergey Butko
CMO & Co-Founder Callpage
Using Sellizer has improved our communication, both within and outside the company. In our internal communication, we use Sellizer to send important documents to ensure that they have not been skipped or missed among many other messages. Moreover, thanks to the use of the tool in communication with potential partners, we can see at what stage our relationship is.
Tomasz Świeboda
Managing Partner Inovo.vc
LinkedIn is the most important channel for communicating with clients. Sellizer allows me to quickly and conveniently send presentations and proposals, and what’s most important, allows me to react quickly to their opening, analyse interest in them and consequently conduct valuable business conversations. I recommend.
Marcin Małaszuk
Sellizer helps us respond to questions from our customers at the right time. Thanks to that we give added value already at the sales stage which allows us to build a relationship with the customer from the very beginning. This is very valuable to us.
Łukasz Białonoga
Although Sellizer can at first glance be seen as a tool only for sending proposals, I can certainly confirm that it also works for sending sales folders, contracts and other documents. Thanks to this, we have a real-time preview of what is the most valuable to the customer in each document (on which parts they spent most of the time) and what needs to be improved.
Michał Boniecki
Sellizer enables a thorough analysis of the customer in terms of interest in our proposal, which helps us save time in the further parts of sales process. When receiving information on how long the customer has been reading each pages of the proposal, I can predict whether the sales process will continue or our proposal is just a market recognition for statistical purposes of the potential customer.
Bartosz Makles
Sellizer has become an inseparable tool for us in communication on several levels. As an intermediary in the logistics industry, we come into contact with both operators and their customers. Sellizer allows us to work with both the first (reporting) and the second (sending proposals) Partners. Thanks to the systematisation and transparency of the activities in Sellizer, we have been able to significantly increase the rate of acquired customers.
Mariusz Korzeniecki
Until now, our knowledge has been ending at the stage of sending the proposal - and thanks to Sellizer - now this is the point where the acquisition of the greatest amount of knowledge about the client begins which allows the marketing team to understand better the needs and match the proposal content to the customers and sales team to contact the customers always at the right time. Thanks to the opportunities that Sellizer gives us, we can everyday increase our chances in a game called sales.
Michał Czuba
Very often we wondered why, despite sending a large number of proposals, many of them still remained unanswered. Thanks to Sellizer, we have structured our sales process, organized sending proposals and gained awareness of their quality. Now we can easily track which parts of our proposals are the most valuable for our customers and continuously improve them. I am pleased that with Sellizer we make better use of our time as well as the potential of our customers.
Grzegorz Jaskot
We sincerely recommend Sellizer. It helps our sales team in daily duties and prioritizing customers. But that's not all. At the department level, it gives us the opportunity to improve the entire sales process based on easily measurable criteria.
Michał Drozda
Thanks to Sellizer we have optimized our process of preparing proposals. With data sets we create tailor-made proposals to meet customers’ needs and expectations, which improves the conversion rate. I’d recommend it to anyone!

Pick Sellizer if you send a proposal and then have to decide who to call, when and with what question.
Pick Papermark if you want to share documents by link and can host the tool on your own server.
Share documents that need an NDA in Papermark, and send sales proposals through Sellizer.
Papermark shares a document by link and shows who opened it. Sellizer runs the whole proposal: it sends it, texts you on the open, shows a heatmap and a session recording, gives Priority and Engagement scores, and then follows up automatically.
Yes, but only on higher plans - below that Papermark generates a link to the file and you send the message from your own inbox. Sellizer sends the proposal from the system, through any channel, and immediately ties it to a recipient and a status.
No. Papermark has no e-signature, and neither does Sellizer - if signing inside the proposal matters to you, neither tool closes that on its own.
Papermark has a free plan and paid tiers at EUR 24, 59 and 99 per month. Sellizer costs USD 17.60 on Solo and USD 28.00 on Team. The team's sheet records these in different currencies, so treat the comparison as indicative. As of August 2026.
When the proposal has to be shared under control: a password and a list of allowed addresses, an NDA before access, a dynamic watermark, folder and file permissions, an audit log and company-account login. On top of that a sales room with a shared action plan, a question asked inside the proposal window and AI analysis of the proposal - Sellizer has none of these. Choose Sellizer when you want to run the proposal from send to decision in one place.
