One DIM policy dispute, one $1M+ carrier refund

Shippers can't control what a carrier decides to charge. But they can control how they respond. Having accurate, accessible data that highlights the real impact of any billing change can make that response much stronger.

Carriers keep finding new ways to charge more: a new accessorial charge, or a policy update buried in the fine print. Alone, each change looks small. Over time they add up to real cost, and most shippers don't have the time or tools to catch them until the impact already shows up on an invoice.

Shippers can't control what a carrier decides to charge. But they can control how they respond. Having accurate, accessible data that highlights the real impact of any billing change can make that response much stronger.

Loop's transportation experts track new carrier fees and changes so our customers can understand the impact. We build reporting that gives shippers clear data on carrier fees, providing them the evidence to act when a change costs real money and breaks the terms of an existing agreement.

Handling an unexpected carrier fee

Knowing a carrier made a change is easy. Knowing what to do about it takes real work.

Before challenging a policy or opening a carrier negotiation, shippers need three answers: what changed, how it affected their transportation spend, and whether the impact lines up with their carrier agreement.

Securing a $1.2M carrier settlement

One shipper faced exactly that situation after a major carrier updated its dimensional (DIM) rounding policy. Loop's transportation team flagged the change early and identified that it could significantly raise shipping charge correction fees.

Loop and the shipper dug into the data together to map what the update meant for the shipper's network. Detailed reporting showed their accessorial charges climbing steadily after the change. That was enough of a signal for the team. They checked the increases against the terms of their negotiated contract.

With that analysis complete, the shipper built a case that the resulting charges fell outside the scope of its negotiated rate cap. The negotiations took several rounds of conversation, with the shipper backing its position with data and contract expertise each time (and a determination to push through difficult  conversations).

The result: a $1.2 million refund.

Catching the policy change early and building a case grounded in data made that possible.

Staying ahead of carrier changes

Carrier policies will keep evolving as networks and economics change. Shippers will always have to manage carrier decisions outside of their control. The difference comes down to whether they have the data, time, and expertise to understand the impact of those changes, and the will to build a case when one violates their agreement.

That is the position Loop puts shippers in. Loop makes sure the shipper sees a change coming and knows what it costs. When the numbers don't add up, they have the data to push for a fair correction that every side can support.
