The Future of Routing: Integrating TMS with External Solutions

In a fast-paced, hyper-connected logistics environment, routing is no longer just a back-office planning tool—it’s a core strategic function. As businesses race to meet rising customer expectations for same-day delivery, cost efficiency, and sustainability, they must also navigate urban congestion, fluctuating fuel prices, and ever-tightening delivery windows. The pressure to optimize routing decisions in real time is growing rapidly.

Traditionally, routing decisions have been managed through Transportation Management Systems (TMS)—enterprise-level platforms like Oracle, SAP, or Blue Yonder. But today, a new generation of external routing solutions—modular, API-driven, cloud-based tools—is gaining traction, particularly in last-mile delivery and dynamic urban logistics.

What’s emerging is not a replacement, but a convergence. Businesses are now blending the strengths of both worlds to build hybrid routing strategies that are fast, flexible, and built to scale.

What’s Inside a TMS?

A TMS is designed to manage complex transportation operations. It handles:

• Route optimization using algorithms like the Vehicle Routing Problem (VRP)
• Carrier selection based on cost, availability, and delivery windows
• Load consolidation and multi-modal transport
• Real-time visibility and compliance tracking
• Integration with ERP, WMS, and order management systems

These features are critical for large-scale logistics and structured transportation environments, such as full-truckload shipments and global operations.

However, traditional TMS platforms often struggle with:

• Real-time responsiveness (e.g., reacting to traffic or weather changes)
• Flexibility for last-mile or gig economy models
• High implementation and customization costs
• Integration with modern, API-first tools

Why External Routing Tools Are Growing

To address these limitations, many companies are complementing their TMS with external routing tools such as Google OR-Tools, Onfleet, Routific, and Samsara. These solutions are:

• API-first: easy to plug into custom apps or platforms
• Real-time: dynamic route updates based on traffic, weather, and demand
• Cloud-based: scalable and cost-effective for startups and enterprise teams alike
• AI/ML-powered: continuously learning from past performance to improve decisions
• Built for last-mile: ideal for urban logistics and complex delivery networks

Use cases include:

• Retail and e-commerce businesses managing last-mile deliveries
• Logistics providers needing flexibility in driver assignments and vehicle constraints
• Companies optimizing perishable goods delivery with time-sensitive windows

What’s Next: The Rise of Hybrid Models

The future isn’t either/or. It’s both.

More companies are choosing a hybrid routing model:

• They use TMS platforms for long-haul, structured routing and compliance.
• They integrate external tools for last-mile optimization, dynamic re-routing, and customer-centric delivery models.

According to Gartner and Grand View Research:

• The global TMS market is projected to grow to $40.3 billion by 2029, driven by cloud adoption and AI integration.
• The external routing solutions market will also grow significantly, especially in retail, e-commerce, and urban logistics, with a CAGR of over 8% toward 2027.

This convergence trend is particularly powerful for organizations that need both efficiency and agility in their logistics operations.
