Less Than Truckload

LTL shipping built on density, not guesswork: simple inputs, predictable rates.

Less than truckload shipping lets you pay for the trailer space you use instead of a full truck. Freight Flex quotes LTL on density, so you only need weight and dimensions or total volume to get started. No NMFC lookup, no commodity reclassification surprises and no chasing multiple carriers for pricing.

What LTL Shipping Is and When It Fits

Less than truckload shipping combines freight from multiple shippers in one trailer, so each shipper pays for the portion of the trailer their freight occupies. It is the right mode when an order is too large for parcel and too small to justify a full truckload. Typical LTL shipments run from one to roughly six pallets, and they move through carrier terminal networks rather than door to door on a dedicated truck.

Quote, Book and Track LTL Online

Customers who prefer a hands-on approach can use the Freight Flex portal to compare live LTL rates, select a carrier, book shipments, generate shipping documents and track freight through delivery. Prefer more support? Our team is still available to manage the process with you.

Density-Based Rates in a Density-Based Market

For decades, LTL pricing hinged on NMFC commodity classifications, and a wrong code meant costly reclassification charges after delivery. The industry has now moved in the direction Freight Flex already priced. Beginning in 2025 the National Motor Freight Traffic Association shifted thousands of commodities to density-based classification, and carriers are enforcing the new rules on every reweigh.

Freight Flex quotes all LTL rates on density. You provide weight and dimensions, or total volume, and we return pricing. There is no NMFC lookup required and no commodity-based reclassification working against your invoice. Accurate measurements at the dock become accurate numbers on the bill.

A Carrier Portfolio Built for Partial Freight

Freight Flex maintains an LTL vendor portfolio of more than 50 national, regional and local carriers, and a service rating is displayed for each one, so you can weigh price against performance instead of booking blind. Behind the portfolio are carrier compliance tools and an agent success team available 24/7 to help reduce cargo theft, fraud and claims and support shipment visibility. The full carrier vetting standards cover active authority, FMCSA safety standing, insurance minimums and fraud prevention monitoring. For freight connected to air programs, Freight Flex is a TSA Certified Indirect Air Carrier with airport delivery support from TSA-compliant drivers.

Billing You Can Actually Close

Partial freight is where surprise accessorial charges live. Our team inspects all carrier charges immediately after delivery and sends a courtesy notification of any additions, so nothing lands on an invoice you have already booked. Invoices close within two business days after delivery. If your freight arrives in an import container, our transloading and drayage teams can move it from the port to palletized LTL delivery in one coordinated plan.

Density-Based Rates, No NMFC Required

Quote LTL with weight and dimensions or total volume. Freight Flex prices on density, which avoids costly commodity reclassifications and aligns with the industry's own shift toward density-based freight classification.

Every Carrier Charge Audited

Our team inspects all carrier charges immediately after delivery and sends courtesy notification of any additions. Invoices close within two business days of delivery, so your accruals stay accurate and your files stay closed.

Planning LTL

Getting partial freight right before it ships: fewer surprises after delivery.

Most LTL problems trace back to the quote, not the road. Accurate inputs, realistic transit expectations and the right carrier match do more for a partial shipment than anything that happens after pickup.

Accurate Dimensions Drive Accurate Invoices

Density is weight divided by cubic volume, measured with packaging included, so the pallet, the crate and the overhang all count. Carriers verify dimensions with scales and dimensioners at the terminal, and a shipment that measures larger than it was quoted gets rebilled across the industry. Freight Flex needs five inputs to quote an LTL shipment. Origin ZIP code, destination ZIP code, weight, dimensions or total volume, and piece count. Get those right at the dock and the density rate you were quoted is the rate that survives the audit. Our team still reviews every carrier charge after delivery, so if an addition does appear you hear it from us first.

When LTL Is the Right Mode, and When It Is Not

LTL earns its keep on shipments of roughly one to six pallets moving on standard timelines through carrier terminal networks. Freight that fills most of a trailer often prices better as a partial or full truckload, and freight that cannot absorb terminal transfers or a wider delivery window belongs with our expedited team on a dedicated vehicle. Import freight is its own case. A container arriving at a port can move through drayage and transloading into palletized LTL deliveries to multiple destinations, which avoids per diem exposure and puts final delivery on domestic LTL economics. Freight Flex plans all of it under one point of contact.
