Choosing between contract and spot freight is one of the most critical decisions for logistics teams. The right mix can deliver cost-control, reliable capacity, and service stability. For shippers working with a transparent freight broker, designing a route guide that balances both is key.
Understanding Contract vs Spot Freight Rates
What is a Spot Rate?
Spot freight rates are one-off, market-driven quotes for a single shipment, typically when you need capacity immediately or the lane is new and untested. They fluctuate daily because of supply and demand, fuel shifts and seasonal peaks.
For example, if a produce shipper discovers a new lane from Dallas to Winnipeg during peak harvest, they may use spot capacity while they evaluate if it qualifies for a contract.
What is a Contract Rate?
Contract rates are negotiated in advance between shippers and carriers (or brokers) for a defined period and lanes. They offer stability in pricing and capacity commitments.
For instance, a retailer shipping dry-van loads on the same lane 50 times a week might sign a 12-month contract rate with a trusted fleet.
How Spot and Contract Markets Interact
Spot rates often act as a leading indicator: when the spot market tightens and rates climb, contract rates tend to follow after a lag of months.
This dynamic means procurement teams must monitor spot-contract spreads to avoid getting locked into rates above market peaks.
Why a Route Guide Matters for Shippers
Defining a Route Guide in Truckload / FTL & LTL Context
A route guide is your structured plan of how freight moves across lanes: which carriers handle them, whether the lanes are contracted or managed via spot, what service levels apply, and how transitions happen when carriers slip.
It covers FTL, LTL and specialty services (reefer, flatbed, dedicated) depending on your network.
Cost, Service and Risk Dimensions of Your Routing Guide
- Cost – Controlled via contract lanes where you commit volume and negotiate accessorials.
- Service – Reliability matters: contracted carriers typically deliver more consistent performance.
- Risk – Spot markets offer flexibility but higher exposure to market volatility and capacity short-falls.
- Without a defined route guide you may fall into “leakage” where contracted carriers decline loads and you default to spot at higher cost.
The Role of a Transparent Freight Broker in Route Guide Design
A freight broker that operates transparently (disclosing carrier names, rates, margin, asset fleets) becomes a partner in helping you build a route guide that you can monitor, measure and trust.
That’s what One Freight Broker offers via carrier-name disclosure, low fixed margin, and fully vetted fleets.
When to Use Contract vs Spot on Your Lanes
Identifying Core Lanes vs Variable Lanes
- Core lanes: high shipment frequency, volume consistency, stable origin/destination pairs. These are strong candidates for contract pricing.
- Variable or emerging lanes: low volume, inconsistent demand, seasonality or pilot runs. These are better suited for spot market until density grows.
Volume, Consistency & Seasonality Criteria
If you move 300+ full-truckload loads a year on a lane with predictable service, a contract makes sense. If you move 2–5 loads per month, spot may be more flexible. As one guide notes: contract rates are ideal for predictable volumes.
Also consider seasonality: a holiday rush or peak-produce season may require spot flexibility.
Hybrid Strategy: Contract + Spot to Build Stability
The most advanced logistics organisations use both. For example: 70% of load volume on contract lanes, 30% of overflow or new lanes on spot. This gives you baseline stability while staying agile.
Tip: build your contract lanes first, then layer spot capacity as backup or growth tool.
How to Structure Contract Agreements for Stability
Lane Profiling, Forecasting & Minimum Commitments
Begin with lane profiling: historical data, directionality, truck type (dry van, reefer, flatbed), dwell and turnaround. Forecast volume and set minimum commitments.
Discuss term length (6–12 months) and renewal conditions.
Accessorials, Fuel, Detention & Drop-Trailer Programs
Contracts must cover accessorials: detention, layover, live-unload, drop-trailer programs. For example, a drop trailer program ensures trailer remains at shipper site overnight reducing detention costs and improving on-time pickup.
In your contract ensure transparency on fuel surcharges, accessorial caps, and how exceptions are handled.
Performance KPIs, Carrier Name Disclosure & Service Transparency
Include Key Performance Indicators (KPIs): on-time pickup/delivery, tender acceptance rate, claims rate, deadhead miles.
One Freight Broker’s model of carrier name disclosure means you know who is hauling your freight, not just an opaque broker network. This aids accountability.
Also specify governance over “back-solicitation” of carriers (i.e., carriers contacting you directly to bypass the broker). That risk undermines your route guide.
How to Manage Spot Market When Needed
When You Should Lean on Spot
Use spot when:
- A new lane is being tested.
- You have seasonal or surge freight beyond contracted capacity.
- Your primary carriers decline loads or capacity tightens unexpectedly.
Risks of Over-Reliance on Spot
- Rates may spike during tight capacity or fuel upheavals.
- Service levels may degrade: carriers may prioritise contract business.
- Budgeting becomes unpredictable.
How Transparent Brokers Mitigate Spot Risk
When you partner with One Freight Broker you gain access to vetted asset fleets, full transparency and backup capacity. Even when you rely on spot, you’re working with carriers you know, metrics you trust, and a partner that integrates spot into a broader route-guide strategy.
Building a Stable Route Guide with One Freight Broker’s Model
Fixed-Low-Margin Brokerage vs Traditional Spread-Based Broker
Traditional brokers earn by spreading (carrier rate vs shipper rate) which may create misaligned incentives. One Freight Broker uses a low fixed margin, removing incentive to inflate spreads.
“You see full carrier cost, we see fixed margin — you win in transparency.”
Full Carrier Name & Rate Disclosure – Why It Matters
You know exactly which carrier hauls your freight, their safety scores, their equipment type. That visibility drives performance accountability and trust.
This model aligns well with shippers demanding transparency and provider accountability.
Vetted Asset Fleets, Drop-Trailer Programs & On-Time Delivery Focus
One Freight Broker’s asset-based carrier fleet is vetted for safety, equipment adequacy (dry van, reefer, flatbed) and service. The inclusion of drop-trailer programs supports efficient turns, lower detention and higher on-time pickup (OTP) performance.
Putting It All Together: Case Example of a Core Lane Transition
Example: A consumer goods shipper had 50 loads/month on Lane A (Chicago → Atlanta), previously unmanaged, booked spot. With One Freight Broker, they audited the lane, shifted 80% to contract with a vetted carrier, included drop-trailer at Atlanta site, set KPI metrics. Result: cost was stable, OTP improved, and spot usage remained only for surge.
This illustrates how a route guide built on contract + transparency embedded into procurement can deliver results.
Practical Steps for Procurement & Logistics Managers
Lane Audit Checklist (volume, service, cost, risk)
- Historical volume and lanes of origin-destination.
- Volatility: how many weeks/months vary >20%.
- Carrier performance: current OTP, claims, detention.
- Cost structure: all-in rate, accessorials, fuel, variation.
- Dedicated vs shared asset usage.
- Risk: what happens when primary carrier falls through?
- Transparency: Can you see carrier name, rate breakdown, service metrics?
RFP Template Considerations (contract vs spot split)
- Define list of core lanes to go into contract.
- Set term length, minimum volume, renewal terms.
- Include accessorial schedule, fuel surcharge transparency.
- Specify carrier name disclosure, scorecards, governance.
- Reserve clause for spot usage and how that will be priced/monitored.
- Ensure no back-solicitation; define prohibited carrier outreach.
Monitoring & Score-carding with Transparent Brokerage
- Set monthly/quarterly scorecards: tender acceptance %, on-time %, detention minutes.
- Track spot-contract spread: if spot rates fall significantly, revisit contract terms.
- Review carrier performance annually: safety, claims, service, cost.
- Conduct periodic route-guide health check: are you still aligned to volume patterns or has the network changed?
FAQs
What is low fixed margin pricing in brokerage?
It means the broker charges a fixed fee (e.g., a percentage or flat fee) over the carrier cost, rather than an undisclosed spread. That aligns broker incentives with your cost-control and transparency goals.
How does carrier name and rate disclosure improve service?
When you know which carrier is hauling your freight and the cost breakdown, you gain visibility into performance, accountability and path for continuous improvement. This transparency supports stronger relationships and better service levels.
Can I convert a spot-only lane into a contract lane?
Yes. Begin by auditing the lane, collecting volume and service data, build density or minimum volume expectations, test with spot, then issue an RFP for contract once you achieve repeatable shipments.
What is a drop-trailer program and how does it fit in route guides?
A drop-trailer program involves placing an empty trailer at your site so your shipper loads at their convenience. The carrier picks up later. This supports faster turn-times, lower detention, and improved service reliability—key to high-service contract lanes.
