Powering Logistics and Healthcare Platforms Across Germany with Seamless PDF and Excel Automation
When ThreeB IT, a German software engineering firm, needed to deliver fast, compliant PDF and Excel generation for logistics and healthcare applications, they faced a challenge familiar to many development teams: building a powerful solution that could scale across industries without compromising data privacy or speed.
The result? High-performance SaaS platforms serving clients from Kuehne + Nagel, one of the world's largest logistics providers, to national healthcare networks managing COVID-19 test documentation, all powered by Iron Software's solution suite.
IronPDF made it possible to build a nationwide COVID testing system in just two weeks. The key part was ready within hours. — Thimo Buchheister, CEO, ThreeB IT
About ThreeB IT
Founded in 2004, ThreeB IT is a software development company based in Ibbenbüren, Germany, building SaaS platforms across logistics, healthcare, and fitness industries.
Their clients include Kuehne + Nagel, the world's leading sea and air freight logistics provider, as well as national healthcare providers and fitness operators.
ThreeB IT develops in close partnership with clients, integrating real-world business processes directly into code.
The Challenge: Rapid, Compliant PDF Generation Across Industries
ThreeB IT specialises in custom software-as-a-service (SaaS) platforms spanning logistics, healthcare, and fitness. After re-establishing the company in 2019, the team focused on building modern, cloud-ready applications that integrate seamlessly with clients' existing systems whilst adhering to strict European data privacy and health regulations.
Their clients needed two critical capabilities:
- Generate mission-critical PDFs with accuracy and speed: From customs declarations to government-approved COVID certificates, every document had to be perfect. With strict GDPR requirements, all processing had to happen on-premises with zero external data transfer.
- Enable Excel-based data exchange that works flawlessly: International clients used wildly different CSV formats across countries, whilst the solution needed to run seamlessly across .NET Framework, .NET Core, and Docker environments without breaking existing systems.
Our goal is always to build software that's fun to develop and performs at the highest level. Iron Software made that possible.
Why Compliance Was Make-or-Break
Here's something often overlooked: European data privacy isn't just about ticking boxes. For ThreeB IT's healthcare clients, a single compliance failure could shut down operations.
Because Iron Software doesn't store any data, GDPR compliance is simple. That's critical for every project we build.
All processing happens on-premises. No data leaves their servers. No third-party dependencies. This simplified compliance audits and gave clients peace of mind.
Solution
After evaluating multiple libraries, including open-source tools and legacy commercial options like Syncfusion, the ThreeB IT team had clear requirements for their ideal solution:
- Lightweight and modular to integrate what's needed without affecting the codebase
- Fast to implement with clear documentation that developers could actually use
- Fully compliant with EU and health data regulations out of the box
- On-premises deployment with no cloud dependency for sensitive data
Iron Software ticked every box. Its modern architecture meant they could select exactly the tools they needed. The documentation was thorough enough to get started immediately. Crucially, everything could run entirely on their own servers, keeping sensitive healthcare and logistics data under complete control.
We simply added IronPDF to an existing project, and the key feature was working within hours.
Their implementation now includes:
- IronPDF for automated document generation, including export forms, shipment papers, and official certificates
- IronXL for high-fidelity Excel import/export to replace CSV handling across multiple country formats
- IronWebScraper for automated website content creation in their new Health & Fitness platform
These three products are part of the Iron Suite, the complete collection of 10 .NET libraries from Iron Software designed to handle everything from PDF and Excel to OCR, QR codes, and beyond.
Real Results in Production
When building software for logistics giants and healthcare networks, you can't afford to compromise. Speed, accuracy, and compliance aren't optional. They're the foundation of everything.
The proof is in the deployment, with ThreeB IT's platforms now serving:
- Kuehne + Nagel's logistics operations across Europe
- Nationwide COVID testing centres throughout Germany
- Health and fitness startups launching digital wellness platforms
The technical wins were significant:
- Hybrid compatibility: Seamless integration with .NET Framework and .NET Core environments
- Docker-ready: Smooth containerised deployments
- Developer velocity: Features that previously took days now take hours
The documentation was fantastic, especially the deployment guides for Docker. It made everything from development to delivery smooth.
Factors Driving Decisions
IronPDF and IronXL now power ThreeB IT's flagship products across logistics, healthcare, and fitness. The company has standardised on Iron Software libraries for all future projects, citing reliability, compliance, and developer experience as key advantages.
We'll integrate at least one Iron Software product in every future project. It's become part of our standard stack.
Compatibility: Iron Software integrated seamlessly into hybrid .NET environments without rewriting legacy systems.
Performance: Enabled rapid feature delivery, with a nationwide healthcare platform deployed in just two weeks.
Security: All data processing remains internal, simplifying GDPR and healthcare compliance.
Developer Experience: Comprehensive examples and Docker-ready deployment guides reduced setup time from days to hours.
