Top Days

Welcome to the Treesoft Top Days 2026!

A Company You Can Experience Firsthand – Two Inspiring Days Focused on Treesoft CAD, Treesoft CRM, Treesoft ERP, and the Treesoft E-Invoicing Toolkit

September 24 and 25, 2026 – live in Lindlar

Experience Treesoft up close: Our Top Days are more than just an in-house exhibition.

Our Top Days give you the opportunity to get to know our entire team, exchange ideas with other users, and gain valuable insights into the latest developments.

Whether you’ve been using Treesoft CAD for a long time, are just getting started, work with Treesoft CRM or Treesoft ERP, or are interested in the Treesoft E-Invoicing Toolkit—there’s something here for you.

What to Expect:

• Exciting workshops and live demos featuring Treesoft CAD, CRM, and ERP, as well as our new e-invoicing toolkit 
• An Overview of All the New Features in Treesoft Office 7.4 – Concise and Practical
• Introduction to the New PLC Wizard
• In-Person Support: Bring your project with you—we'll take a look at it together 
• Direct communication with our development and support team
• Networking over delicious catering and, later, Kölsch on tap

“The Top Days are like a hands-on software service.”

Why you should come:

• In this presentation, we'll provide you with information on current topics related to Treesoft and present the development plan for all Treesoft products.
• In the workshops, we'll work with you and other users to address your questions.
• You'll learn all about the new features in Treesoft CAD, Treesoft CRM, and Treesoft ERP.
• We'll also briefly touch on the topic of e-billing.
• The information published online on this topic is often contradictory, difficult to understand, or simply incorrect.
• In the workshop “Everything You Need to Know About E-Invoicing,” you can then learn all about the topic. We’ll also introduce you to the Treesoft E-Invoicing Toolkit, an on-premises solution that can be installed locally to convert PDF invoices into ZUGFeRD or XRechnung invoices.

Why It’s Worth Your While to Visit

Treesoft is more than just software. We don’t just develop for you—we develop together with you. Your feedback is directly incorporated into our ongoing development. At the Top Days, you’ll get to know our team in person, share your own questions and projects, and gain direct insight into our product planning.
