How to Bid on Freight Contracts
Winning contract freight requires more than offering the lowest rate. Shippers evaluate safety records, service history, capacity commitment, and technology capabilities. This guide walks you through the entire bidding process — from finding bid opportunities to calculating your rate to submitting a winning proposal.

Key Takeaways
- Most contract freight is awarded through an RFP, with large shippers running annual bids in Q4 (October–December) for lanes that start the following January.
- Build every bid rate from your true cost per mile, add a minimum margin of about $0.15–$0.30 per mile, factor in deadhead, then benchmark against a contract rate index for the lane.
- Never bid below your cost floor — an unprofitable contract locks up your capacity for the full term, usually 12 months.
- Only bid on lanes you can realistically cover 90% or more of the time; over-committing and rejecting tenders damages your shipper reputation.
- Shippers score more than price — safety record, service history, capacity commitment, and technology/compliance all weigh into the award.
Understanding the RFP Process
Most contract freight is awarded through a Request for Proposal (RFP) process. Here is how it works:
Shipper Publishes Lane Requirements (Oct-Dec)
Large shippers release RFPs specifying every lane they need covered: origin/destination, weekly volume, equipment type, service requirements, and contract period. These go to carriers and brokers they have relationships with or who are registered in their carrier database.
Carriers Submit Bids (2-4 Week Window)
Carriers review the lanes, calculate their rates, and submit bids on the lanes they want. You do not have to bid on every lane — only bid on lanes where you have capacity and the route fits your operation.
Shipper Evaluates & Awards (Dec-Jan)
Shippers evaluate bids on rate, safety, service history, and capacity. They typically award each lane to a primary carrier and one or two backup carriers. Awards are communicated with rate confirmations or formal contracts.
Contract Execution & Tender Flow (Jan+)
Loads start flowing. The shipper tenders loads through their TMS; you accept and cover them. Your tender acceptance rate (target: 90%+) determines whether you keep the contract for the full term.
Finding Bid Opportunities
Register with shippers directly — Large shippers like Walmart, PepsiCo, and Tyson have carrier onboarding portals. Register your carrier profile, insurance, and safety data. When RFP season arrives, they invite registered carriers to bid.
Work through brokers — Large brokers (TQL, CH Robinson, Echo) manage contract freight for major shippers. Build relationships with broker reps who can include you in their contract freight lanes.
Use carrier matching platforms — Services like DAT Direct, Parade, and Highway connect shippers with carriers for contract freight. These platforms are increasingly where mid-size shippers run their RFPs.
Leverage your dispatch service — A dispatch service with existing shipper and broker relationships can get you into bid opportunities that individual carriers cannot access on their own.
Calculating Your Bid Rate
Your bid rate must be competitive enough to win but profitable enough to sustain. Here is the formula:
Bid Rate Calculation
Step 1: Calculate your cost per mile (fuel + insurance + truck payment + maintenance + tires + permits + salary)
Step 2: Add your target profit margin ($0.15-0.30/mile minimum)
Step 3: Factor in deadhead for that lane (empty repositioning miles)
Step 4: Benchmark against DAT contract average for that lane
Example: CPM $1.80 + $0.25 margin + $0.10 deadhead factor = $2.15/mile base rate + FSC
Never Bid Below Your Cost
Two pieces of math make or break a bid, so do them precisely. Nail your true cost per mile (use our cost-per-mile calculator if you do not track it yet), then price in empty repositioning with the deadhead miles calculator. Because a contract rate is locked for the full term while spot pricing floats, build in enough margin to survive a rising market — see spot market vs. contract freight and how contract rates are set for the current dynamics. Most contract awards quote a base linehaul rate plus a separate fuel surcharge, so confirm whether the FSC is pegged to a published index before you commit your linehaul number.
What Shippers Evaluate in Your Bid
1. Rate Competitiveness (30-40% of decision)
Your rate must be within the competitive range. Being the cheapest is not required — being 5-10% above the lowest bid is usually fine if your other factors are strong. Being 20%+ above will eliminate you.
2. Safety Record (20-25%)
Clean CSA scores, Satisfactory safety rating, current insurance, no recent out-of-service orders. Large shippers automatically disqualify carriers with high CSA percentiles.
3. Service History (15-20%)
On-time delivery percentage (95%+), tender acceptance rate (90%+), claims history, and communication quality. Shippers check their own records if you have hauled for them before and may check references from other shippers.
4. Capacity Commitment (10-15%)
Can you actually cover the volume? How many trucks do you have on that lane? Do you have backup capacity for breakdowns? Shippers hate awarding contracts to carriers who then reject tenders because they over-committed.
5. Technology & Compliance (5-10%)
Can you integrate with their TMS for electronic tenders? Do you have GPS tracking? Are you registered in required carrier databases? Larger shippers require EDI capability or web portal access.
Common Bidding Mistakes
Bidding on too many lanes — Only bid on lanes you can realistically cover 90%+ of the time. Over-committing and then rejecting tenders destroys your reputation faster than losing a bid.
Not accounting for all costs — Include deadhead repositioning, detention time, seasonal volume fluctuations, and insurance increases in your rate calculation. Underpricing means losing money for 12 months.
Ignoring contract terms — Read every clause. Pay attention to liability, indemnification, volume commitments (or lack thereof), and termination provisions. See our contract terms guide.
Missing bid deadlines — RFP windows are tight (2-4 weeks). Set calendar reminders for bid season (Q4) and respond promptly. A late bid is an automatic rejection regardless of how good your rate is.

How Our Team Manages Your Bids
Bid rate benchmarking
We benchmark every bid against DAT contract averages, your specific cost per mile, and historical lane data. Every bid is calculated to be competitive and profitable — never a guess.
Access to bid opportunities
Through our broker and shipper network, we connect our carriers with contract freight opportunities that individual owner-operators cannot access independently. Our relationships open doors to contract lanes from major shippers and large brokerages.
Frequently Asked Questions
When is freight bid season?
Most large shippers run their annual freight RFPs in the fourth quarter — typically October through December — so awarded lanes start flowing at the beginning of the new year. Mid-size shippers increasingly run rolling or mini-bids throughout the year on carrier-matching platforms, so register early and watch for off-cycle opportunities.
How much should I bid on a freight contract?
Build your bid from the bottom up: start with your true cost per mile (fuel, insurance, truck payment, maintenance, tires, permits, and pay), add a minimum margin of roughly $0.15–$0.30 per mile, add a factor for that lane's deadhead, then benchmark the result against a contract rate index for the lane. Never bid below your cost floor just to win — an unprofitable contract locks up your capacity for the full term.
Do I have to bid on every lane in an RFP?
No. You should only bid on the lanes you can realistically cover 90% or more of the time. Cherry-pick lanes that fit your equipment, your home base, and your backhaul opportunities. Over-committing and then rejecting tenders damages your reputation with the shipper far more than simply not bidding on a lane.
What is the difference between contract and spot rates when bidding?
A contract (RFP) rate is a locked rate you commit to for a defined term — usually 12 months — regardless of how the market moves, in exchange for steady volume. A spot rate is negotiated load-by-load and swings with supply and demand. When bidding contracts, build in enough margin to survive a rising market, since you can't re-price mid-term.
