How Ensinger Polska strengthened customer relationships with Microsoft Dynamics 365 Sales
Case Study
Location
Poland (HQ in Germany)
Industry
Plastics manufacturing
Solution
Microsoft Dynamics 365 Sales + integration with Microsoft Teams, Outlook, SharePoint, and 3CX telephony
Ensinger is an international company founded in 1966, specializing in high-performance plastics for industries such as machinery, aerospace, medical, construction, and food processing. Speed and quality are their hallmarks.
From strong relationships to stronger processes
At Ensinger Polska, sales teams worked in a partner-based model – each customer account was typically managed by two people. This fostered close relationships and a personalized approach but required smooth knowledge-sharing and access to up-to-date information.
Previously, collaboration was based mainly on Excel files and direct communication. While this setup worked well for daily tasks, it began to show limitations as the customer base grew and processes became more complex.
The solution
A CRM that supports the way the team works
The implementation of Microsoft Dynamics 365 Sales aimed to make the daily work of sales engineers easier – without forcing them to change how they operate. The goal was to shape the system around how they actually work: in pairs, on the move, with a strong focus on speed and responsiveness.
The first phase focused on:
- Building a centralized database of customers and contacts
- Enabling two account managers to work on the same record
- Integrating 3CX telephony (logging calls and adding notes)
- Connecting Dynamics with Outlook, Teams, and SharePoint to enable seamless collaboration and document access - all without leaving the CRM
“We chose to work with Atteli because they stood out from the beginning with their professionalism, deep expertise, and strong team of specialists. Throughout the project, we could count on real support tailored to our needs. The project was run efficiently, on time, and with full understanding of our business. I truly value this collaboration and would describe it as professional, modern, and reliable.”
Robert Antkowiak, Sales Director, Ensinger Polska
