What Questions to Ask Your TMS Vendor About Extensibility

Extensibility is a key feature of a Transportation Management System (TMS) that allows it to grow and adapt with your business. For trucking companies and field service applications, a TMS with strong extensibility features ensures long-term value and flexibility. Here are essential questions to ask your TMS vendor about their system’s extensibility.

**1. What Extensibility Options Are Available?**

Understanding the extensibility options is fundamental. Ask if the TMS supports plugins, modules, and APIs that allow you to extend its functionality.

**2. How Easy Is It to Add New Features?**

Adding new features should be straightforward. Inquire about the process for adding new features or integrations and whether it requires vendor assistance or can be done in-house.

**3. Can Third-Party Applications Be Integrated?**

Integration with third-party applications can enhance functionality. Ask if the TMS allows for seamless integration with third-party software and what methods (e.g., APIs, webhooks) are available.

**4. How Does the TMS Support Custom Development?**

Custom development can tailor the TMS to your specific needs. Inquire if the system supports custom development and what tools and documentation are provided for developers.

**5. What API Capabilities Are Available?**

APIs are crucial for extensibility. Ask about the available API endpoints, their documentation, and how well they support custom integrations and data exchange.

**6. How Does the System Handle Versioning and Compatibility?**

Compatibility with future updates is essential. Inquire how the TMS handles versioning of extensions and ensures compatibility with future system updates.

**7. What Support Is Available for Extensibility?**

Comprehensive support is crucial for successful extensibility. Ask about the level of support available for extending the system, including access to technical experts and developer communities.

**8. How Is Data Security Managed in Extensions?**

Security is paramount when extending the system. Inquire about the security measures in place to protect data within custom extensions and integrations.

**9. Can the TMS Scale with Custom Extensions?**

Scalability is key to future growth. Ask if the TMS can scale effectively with the addition of custom extensions and increased data volumes.

**10. What is the Vendor’s Experience with Extensibility?**

Finally, evaluate the vendor’s experience with building extensible systems. Request case studies or references from other trucking companies in segments like liquid and dry bulk, chemical transportation, petroleum transportation, and fuel transportation to understand their success and satisfaction.


Extensibility ensures that your TMS can grow and adapt with your business needs. By asking the right questions, you can ensure your TMS vendor provides a flexible, secure, and scalable system that supports custom development and integrations. A highly extensible TMS will keep your fleet running smoothly and your business competitive in the dynamic trucking industry.
