Multi-Carrier Parcel Shipping: Why One Carrier Isn't Enough
What is the difference between managed TMS and managed transportation, and which model fits your supply chain? This guide breaks down both approaches, compares them side by side, and walks you through how to evaluate the right fit based on your team's capabilities and operational goals, including how Redwood's Open 4PL model supports both options.
What is managed transportation?
Managed transportation is a fully outsourced logistics model where a partner takes over the daily work of moving your freight. This means they handle carrier selection, load planning, shipment tracking, and problem resolution on your behalf. You are not just buying software. You are getting a dedicated team with the processes and technology to run your transportation management operation.
Think of it this way: when you hire a managed transportation provider, they become your external logistics department. Your internal team can step back from the daily grind of chasing carriers and resolving delivery exceptions. Instead, you focus on your core business while the partner keeps freight moving.
A typical managed transportation engagement covers several core functions working together:
- Carrier procurement and management: The partner sources carriers, negotiates rates, verifies insurance, and monitors on-time performance across your network.
- Load planning and execution: They handle daily load tendering, shipment tracking, and exception management. If a truck no-shows, they find a backup.
- Freight audit and payment: Every invoice gets validated against contracted rates before you pay it. This catches duplicate charges and accessorial billing errors.
- Reporting and analytics: You receive KPI dashboards and regular business reviews that show cost trends, service performance, and areas for improvement.
The result is a single partner accountable for your freight outcomes, not just a piece of software sitting on a server.
What is a managed TMS?
A managed TMS (managed transportation management system) is a model where you keep ownership of your TMS platform, but a logistics partner handles the technical side of running it. That includes system configuration, software updates, data integrations, and performance tuning. Your internal team still books the freight and talks to carriers every day. The partner just makes sure the technology underneath works properly.
A transportation management system is a major investment. But many companies struggle to maximize their technology ROI because they lack the IT resources to maintain the software. Routing rules go stale. Integrations break. Reports stop reflecting reality. A managed TMS provider fills that gap so your operations team can focus on shipping, not troubleshooting software.
Here is what a managed TMS engagement typically includes:
- System configuration and upgrades: The partner keeps your TMS settings current, applies patches, and aligns the software with your evolving business rules.
- TMS integration management: They connect your TMS to your ERP, warehouse management system, and carrier platforms using EDI or API. This eliminates manual data entry and reduces errors.
- User support and training: Your team gets a dedicated resource for troubleshooting issues and learning new features, which speeds up adoption.
- Optimization and reporting: The partner tunes routing logic, updates carrier scorecards, and generates analytics so the system actually saves you money on every shipment.
In short, you own the technology and the operations. Your partner owns the technical upkeep.
How managed transportation and managed TMS compare
These two models solve different problems. Managed transportation solves an execution problem (you need someone to run your freight). Managed TMS solves a technology problem (you need someone to run your software). The table below lays out the key differences.
| Dimension | Managed Transportation | Managed TMS |
|---|---|---|
| Scope | Full operational execution plus technology | Technology layer only |
| Daily decisions | Partner makes routing and carrier choices | Your team makes routing and carrier choices |
| People | Partner provides a dedicated ops team | Your team runs operations |
| Technology | Partner uses their TMS or yours | You own the TMS, partner manages it |
| Typical pricing | Per shipment or percentage of freight spend | Fixed monthly fee |
| Best for | Shippers who want to fully outsource execution | Shippers with strong ops teams who need tech support |
You do not always have to pick one or the other. Some shippers use managed TMS for their standard truckload freight while layering in managed transportation services for more complex modes like LTL or cross-border. A 4PL logistics provider with an open ecosystem approach can help you blend both models without forcing you into a rigid, one-size-fits-all contract.
When should you choose managed transportation?
If your team is constantly putting out fires, struggling to find capacity, or dealing with missed pickups, you likely have an execution problem. Managed transportation is built for this situation.
Consider managed transportation if any of these sound familiar:
- Your logistics team lacks the bandwidth to manage carriers and daily shipment execution.
- Service failures, late deliveries, or inconsistent transit times are becoming routine.
- Freight spend is growing, but you do not want to hire additional logistics headcount.
- You want one partner who is fully accountable for on-time delivery and cost performance.
This model works especially well for mid-market companies whose supply chains have outgrown their internal capabilities but are not large enough to justify building a full in-house logistics organization.
When should you choose managed TMS?
If your operations team is capable but frustrated by clunky software, broken integrations, or reports that do not reflect reality, you likely have a technology problem. Managed TMS is designed for exactly this.
Consider managed TMS if any of these apply:
- You have a skilled internal team but no dedicated supply chain technology resources.
- Your current TMS is underutilized or poorly connected to your ERP and carrier systems.
- You want to keep full control over carrier relationships and daily routing decisions.
- You need help with system upgrades, data mapping, or analytics without changing how your team operates day to day.
Many shippers start with managed TMS to get their technology foundation in order. As their network grows more complex, they expand into managed transportation for specific lanes or modes. The key is working with a partner flexible enough to support you at every stage.
How to evaluate a managed transportation or managed TMS partner
Not every provider offers both models, and some blur the lines in ways that create confusion. Before you sign anything, ask pointed questions to make sure the partner actually fits your needs.
Here are the criteria that matter most during your evaluation:
- Flexibility: Can the partner support managed transportation, managed TMS, or a hybrid of both?
- Technology openness: Do they require their proprietary software, or can they work within your existing systems?
- Integration capability: How do they connect to your ERP and warehouse platforms? Do they have proven experience with EDI and API connections?
- Governance model: What KPIs, SLAs, and reporting cadence will be in place? How are exceptions handled?
- Scalability: Can the partner grow with you as shipment volumes increase or your network expands into new regions?
- Transition support: What does onboarding look like, and how long does implementation realistically take?
A strong partner will share their standard operating procedures early and introduce you to their implementation team before the contract is signed. Ask to review published case studies so you can see how they have structured similar engagements.

You can choose managed transportation, managed TMS, or a custom combination of both based on what your business actually needs today, with the flexibility to adjust as things change.
Our approach pairs deep logistics execution expertise with RedwoodConnect, our integration platform that links your systems, carriers, and partners into a single connected supply chain. We do not force you onto a proprietary platform or lock you into a rigid service bundle. Instead, we meet you where you are and build from there.
Whether you need a full team running your daily freight or a technology partner keeping your TMS optimized, we can structure a solution that fits. If you are weighing your options, contact Redwood to start the conversation.
Frequently asked questions
Can you use managed transportation without replacing your current TMS?
Yes. Many managed transportation providers can operate directly within your existing TMS environment, handling daily execution while you retain ownership of the software and data.
What KPIs should you track in a managed transportation or managed TMS engagement?
Common KPIs include on-time pickup and delivery rates, cost per shipment, tender acceptance ratios, and invoice accuracy. The right metrics depend on whether your primary goal is cost reduction, service improvement, or both.
What data and integrations should be ready before outsourcing transportation management?
At minimum, you will want clean order data, current carrier rate agreements, and connectivity between your ERP and the partner's systems via EDI or API. A good partner will assess your readiness and help with data mapping during onboarding.
