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.

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!

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.

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.

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.

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.

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.

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.

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.

Frequently asked questions (FAQ)

  • What types of companies benefit most from Sellizer?

    Sellizer works best for B2B companies with sales teams of several people or more that regularly send PDF proposals - ideally a few per week, with sales cycles ranging from one week to several months, where the deal value justifies individual contact with the client.

  • How do we know the client actually read the proposal and didn't just open it?

    Sellizer tracks not only when the proposal was opened, but also the time spent on each page. This way you can see exactly what caught the client's attention and what they were considering. On top of that, the system shows how many people in the organisation viewed the proposal - so you can tell whether the document is being shared internally and who else is involved in the decision.

  • How quickly do we get notified when a client opens a proposal?

    Instantly. On the first open, the salesperson receives both an SMS and email notification. For subsequent opens - an email. Notification type and frequency are configurable. If the client hasn't opened the proposal, the system can automatically send a follow-up reminder.

  • How long does implementation take?

    Creating an account takes 30 seconds. For teams of 3 or more, we offer free onboarding in two steps: configuration with the admin (1.5h) and training for the entire team (1h). We teach not just how to use the system, but above all how to leverage proposal data in everyday client conversations.

  • Is Sellizer GDPR compliant?

    Yes. The proposal recipient views it in a browser where they are asked to accept cookies - just like on any website. Acceptance rates are close to 100%. You remain the data controller for your clients' data; Sellizer acts as the data processor on your behalf and applies the highest security standards.

  • What tools does Sellizer integrate with?

    Sellizer integrates with CRMs: Pipedrive, Livespace, Bitrix24, Raynett, Firmao, HubSpot, MS Dynamics Sales, Zoho CRM, Monday, Salesforce, and Baseline™. We also support Outlook (desktop app and web version), the CallPage system, and Comarch ERP XL. An API is also available for custom integrations.

  • What are the pricing plans and can I try it for free?

    Available plans are Solo ($17.60/month net with annual subscription), Team ($28/month net) - the most popular choice, and Enterprise with custom pricing. Before purchasing, you can try Sellizer free for 14 days with the full version of the product, no credit card required.

  • Can I use my own domain and logo?

    Yes. Sellizer allows you to configure your own domain and logo - the proposal recipient sees only your brand. In the Team plan, customisation is free; in the Solo plan, it's a one-time fee of 199 PLN.

  • How is Sellizer different from email open tracking plugins?

    Sellizer tracks proposal opens, not email opens - a crucial difference, because opening an email doesn't mean the recipient read the proposal. Sellizer shows exactly which pages the client viewed and how much time they spent on each.

  • How do clients actually use Sellizer in their sales process?

    The most common use cases include: reaching out to clients the moment they're actively reviewing the proposal; identifying returns to the document as a buying intent signal; refining materials before a meeting based on what caught the client's attention; and optimising proposal content based on engagement data.
