Qwilr turns a proposal into an interactive web page with signature and payment. Sellizer handles what happens after you hit send: an SMS the moment it opens, heatmaps, session recordings and automated follow-ups.
Start freeYou can build a proposal in either, and both show whether the client opened it. The difference is whether the look of the proposal matters most, or what happens to it after sending.
An interactive proposal in your colors, with e-signature and payment inside. The number of seats is built into the plan.
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.
If you only need a signature at the very end, send the proposal through Sellizer and sign the contract in the e-signature tool you already use.

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 Qwilr if you want the proposal to be an interactive page that the client signs and pays in one place.
Send and track the proposal in Sellizer, and sign the contract in the e-signature tool you already use.
Qwilr builds the proposal - an interactive web page with e-signature and payment. Sellizer watches what happens to it after you send: an SMS the moment it opens, heatmaps and session recordings, and Priority and Engagement scores worked out automatically, with no thresholds to set. On top of that, automated follow-ups, which Qwilr does not have.
No. Sellizer sends and tracks the files you already have - PDFs, decks, documents. If you want a proposal built as an interactive web page, Qwilr does that better. What Sellizer gives you instead is data on how the recipient actually read your proposal, and follow-ups sent on your behalf.
No. Qwilr has both - signature and payment inside the proposal, with a 0.09% fee on the lowest plan and no fee on the higher ones. Sellizer focuses on tracking and follow-up; if signature and payment inside the proposal are critical for you, that is an argument for Qwilr.
Dollar for dollar, yes: Sellizer costs USD 17.60 per user per month on Solo and USD 28.00 on Team, while Qwilr charges USD 35, 55 and 75 across its plans. Qwilr also bakes seat counts into the plan - 1, 5 or 10 people, with extra seats costing more; Sellizer has no minimum. As of August 2026.
When your proposal should be a web page - interactive blocks, embedded video, a pricing calculator, conditional content, plus signature and payment in one place. That is Qwilr's core. Choose Sellizer when you already have your proposals and what you lack is knowing who reads them, and the discipline to follow up.
