Freight costs rarely explode all at once. They creep.

One month it is a few more detention invoices. Next month it is a handful of reweighs, a couple of reclassifications, and a new fuel surcharge baseline that never quite comes back down. By the time the CFO asks why transportation spend is up 8 to 12 percent while shipment count is flat, we are stuck pointing at a messy pile of line items and saying, "It is complicated."

It is complicated, but it is not mysterious. Our industry has a handful of repeat offenders that cause cost creep, and they show up in almost every network once volume and exception counts hit a certain scale.

The creep usually starts with tiny exceptions

Most cost creep is not "rates went up". It is process debt.

Here is what is usually broken:

• Appointment discipline breaks down. A shipper is not ready, a carrier arrives early, a receiver squeezes labor, and suddenly detention becomes normal instead of rare.
• Shipment data quality gets sloppy. NMFC class, weights, dims, accessorial codes, and reference numbers drift. LTL carriers and parcel systems catch it later and bill it back.
• Tendering turns reactive. We stop routing guide compliance because we are busy. More loads go to spot, more loads go to the loudest email in the inbox, and costs climb quietly.
• Claims and OS and D incidents rise. Not always catastrophic, just enough to add reships, write-offs, and expediting.
• Invoices are approved without strong match rules. If our AP team is drowning, they will pay to keep freight moving.

Why does it keep happening? Because the feedback loop is slow.

Detention might show up 30 days later on an invoice. Reclass might arrive 45 days later. A lane that was supposed to be on contract drifts to spot and we only notice when the quarterly review comes around. Operationally, we experience the pain today. Financially, we see it weeks later, when it is harder to tie back to the dock door and fix.

The industry is adding pressure in all the wrong places

Even when linehaul rates soften, total landed transportation cost does not automatically fall.

A few trends are making cost creep more likely:

• More complexity in networks. More SKUs, more ship-to points, more small orders. That pushes us toward LTL, multi-stop FTL, cross-docks, and pool distribution. More touches means more chances for accessorials and errors.
• Receivers are tightening appointment windows. That is good for their labor planning, but it shifts risk to carriers and shippers. Detention and layover become a regular budget line instead of an exception.
• Visibility expectations are higher. Shippers and customers want proactive updates, but many ops teams still rely on manual check calls and email threads.
• Audit exposure is growing. Carriers have gotten better at automated billing adjustments. If weight and class do not match the tariff and your BOL, you will hear about it.

We also have a technology gap in the middle. Many of us run a TMS, a WMS, and an ERP, but the workflows between them are held together by spreadsheets and tribal knowledge. When a planner is out sick, routing guide compliance drops. When a new customer launches, master data quality takes a hit. That is where creep thrives.

We need a practical path forward, not a new dashboard

The fix is not "watch spend harder". The fix is to shorten the feedback loop and harden the handful of decisions that drive most of the dollars.

A practical approach works in three layers.

First, make accessorials measurable and annoying

Accessorials should not be treated like weather. They are operational signals.

Start by tracking accessorials by reason code, facility, carrier, and customer. If you cannot break them down, you cannot fix them.

In many networks, 60 to 80 percent of accessorial spend comes from three buckets: detention, lumper, and LTL adjustments. If you focus there, you will see results fast.

Then set a rule: every detention invoice needs a root cause tag. Not a novel. One of five tags is enough, like shipper not ready, receiver delay, early arrival, appointment miss, or driver error.

Second, lock down shipment data where it enters the system

Most reweighs and reclasses are self-inflicted.

If your WMS is not capturing weights and dims accurately, you are feeding bad inputs into the TMS and into the BOL. If your team is copying accessorials from the last shipment, you are basically guessing.

Quick wins:

• Require weight and dims fields for LTL and parcel before a label or BOL can print.
• Standardize NMFC and class by SKU or by product family. Do not let it be a free text field.
• Add a simple pre-tender validation in the TMS: missing appointment, missing PO reference, missing trailer type, or inconsistent accessorials triggers a stop.

We are not trying to be perfect. We are trying to stop preventable adjustments that hit 30 to 90 days later.

Third, treat routing guide compliance like a control, not a preference

If your routing guide compliance drops from 90 percent to 70 percent, you have effectively given yourself a rate increase.

The best ops teams run a weekly compliance review that takes 30 minutes:

• Top 10 lanes by spend
• Spot vs contract mix
• Primary carrier acceptance rate
• Reasons for bypassing the guide

When you see bypass reasons like "no time" or "could not find rate confirmation", that is not a carrier problem. That is process.

This is where tools can help. Debales.ai is worth a look if you want to reduce manual exception chasing and tighten up billing and shipment data workflows without adding headcount.

Things we can do this week that actually move the needle

If you are a logistics manager or running a 3PL ops floor, here are actions you can start immediately.

Run a 14-day accessorial sprint

Pull the last two weeks of invoices and list every accessorial.

• Group by facility and by customer
• Identify the top two reasons
• Assign one owner per facility to fix the root cause

Even a modest reduction matters. Cutting detention by 20 percent in a network that spends $50,000 a month on it is $10,000 a month back to the business, and it also improves carrier relationships.

Add a "no BOL without" checklist

Before the BOL prints, require:

• Verified weight and pallet count
• Correct shipper and consignee address and dock instructions
• Appointment number if required
• Accessorials validated, not copied

You can do this with TMS rules, a WMS prompt, or a simple SOP and supervisor sign-off. The point is to stop bad data at the source.

Audit 25 random shipments for invoice match quality

Pick 25 shipments across LTL, FTL, and drayage.

Check:

• Rate confirmation matches invoice
• Fuel surcharge matches the agreed index
• Accessorials have supporting documentation
• Stop charges and detention have time stamps

You will find money. Most teams do. And the bigger win is that you will find patterns.

Tighten appointment discipline with one email template

Carriers and receivers are busy. Make it easy.

Create a standard appointment confirmation template that includes:

• Appointment date and window
• Facility contact name and phone
• Detention policy and required check-in steps
• Required reference numbers

Then enforce it. If we do not confirm the appointment, we should not be surprised when we pay for confusion.

The mindset shift that stops cost creep

Freight cost creep is not a finance problem. It is a signal that our operating system is leaking.

When we treat accessorials, reclasses, and invoice noise as unavoidable, we train the network to keep producing them. When we treat them as defects with owners, they start to disappear.

The challenge is simple: pick one leak and make it embarrassing for it to exist next month.
