Lorries, Stalko - Case Study

How Lorries and Stalko use Sellizer at every stage of sales — from the first catalog to the final proposal

Stalko is a manufacturing company in the metal industry selling, among other things, car trailers under the Lorries brand, heating equipment, and sorting machines. The diversity of industries and clients (from dealers to manufacturers) makes it crucial to tailor communication to the recipient's needs from the very first contact.

Challenge

The sales team needed a tool that would allow them to better:

• prepare for client conversations,
• verify client engagement at every stage of the funnel,
• check what works in sales materials and what needs improvement,
• tailor the proposal to the market segment,
• test new proposal elements and observe client reactions.

 

Solution

Lorries and Stalko implemented Sellizer as a permanent element of the sales process across 3 sales departments:

 

At the client verification stage

The team sends product catalogs through Sellizer to check what catches the recipient's attention before the meeting. This way, the sales rep better prepares the conversation — knows what to focus on and what to skip. This is a time saver for both the sales rep and the client, who is interested in specific information.

After sales meetings

Materials (presentations, proposals, price lists) are sent using Sellizer, which enables:

• tracking opens and engagement,
• follow-up at the moment when the client is active or at a later time determined by the department's sales process
• assessing whether the client has actually reviewed the materials before moving further in the funnel.

 

What other benefits does Sellizer bring to Lorries and Stalko's sales teams?

Material optimization

Analysis of 60+ sends showed that the presentation lost attention halfway through. The team restructured the layout, moving key content to the beginning. Result:

• greater engagement,
• better conversations,
• less time on guesswork, more on specifics
• greater client focus on the proposal's value relative to their needs.

 

Proposal personalization for ICP segments

Sellizer revealed that segments (e.g., trailer dealers vs. boat manufacturers) react differently. Proposal and presentation segmentation was introduced - different content, slides, and differentiators for each group. Conversion increased.

 

Testing new elements

The team started experimenting with additional value propositions in proposals. Thanks to data from Sellizer, they know whether the client stopped on that page and whether it's worth revisiting in the conversation.

 

Sorting machines segment

Thanks to Sellizer, the team gained a better understanding of who reviews the proposal on the client side and what is important for each role in the decision-making committee.

 

What Lorries and Stalko particularly value in Sellizer:

• SMS notifications about proposal opens – the ability to react immediately,
• Clear presentation of multiple attachments.
  
  

“Sellizer allowed us to stop guessing. Instead of asking whether the client saw the proposal - we know it right away. Thanks to this, we can smoothly transition to the conversation.”

Who is this scenario for?

For teams that:

• serve multiple segments and need to tailor proposal content,
• want to prepare based on data, not guesswork,
• operate in a long or complex sales process,
• test new proposal elements and want to measure their effectiveness,
• want a simple solution that provides clear data and can be used by anyone in the sales department,
• are looking for a solution that offers SMS alerts.
