The Hidden Fees That Spike During Peak Season (And How to Avoid Them)

Written by Alejandro Garcia - FTL Manager | Sep 15, 2025 7:43:00 PM

Peak season always brings challenges. But beyond the obvious costs, there’s another layer of expense that often catches shippers off guard: hidden fees.

Detention, redelivery, accessorials, and re-bills all spike during this time of year. They don’t make headlines like spot rates, but they can erode margins just as quickly. And for many shippers, they appear as frustrating “surprise” charges long after the load has moved. 

The good news is, with the right preparation and a proactive partner, many of these costs can be avoided altogether.

When networks are stretched thin, there’s little room for error. A truck waiting too long at a dock racks up detention charges. A missed appointment window triggers a redelivery fee. And accessorials like liftgate service or limited access delivery, often slip through quoting but show up later on the invoice.

Re-bills are another pain point. During peak season, carriers audit aggressively to protect their capacity. If weights, dimensions, or freight classes don’t line up, you’ll see the correction reflected in your bill. What feels like a small oversight in planning can turn into a big financial hit.

Individually, these charges may look small $150 here, $200 there. But when volumes surge, they add up fast. Suddenly, the profitable lane you booked isn’t profitable at all. Even worse, these costs are unpredictable. They throw off budgets, strain customer relationships, and leave teams scrambling for answers.

The key to controlling hidden fees is anticipation. In freight, waiting to react almost always costs more than planning ahead. That’s why the smartest shippers don’t just track invoices after the fact they look for potential risks before the truck even hits the dock.

Anticipation starts with the basics:

  • Double-checking dimensions
  • Confirming freight class
  • Accounting for every accessorial before tendering the load
  • Booking realistic appointment windows

Just a few minutes of preparation can save hundreds in re-bills and prevent costly detention or redelivery charges. But anticipation doesn’t end at planning, it continues while freight is on the move. Real-time monitoring means you spot delays from weather, drivers, or facilities before they turn into fees, giving you the chance to act early with reroutes, adjusted schedules, or timely updates to customers.

We know hidden fees don’t just raise costs, they create uncertainty. That’s why we build prevention into our process. We validate shipment details upfront, monitor freight in real time, and keep you updated before issues escalate.
