Accessorial Charges: What They Should Cost and How to Audit Them

Published May 29, 2026 · By Rob Eller

Accessorials are the extra line items carriers add to the base linehaul rate. They cover services beyond standard dock-to-dock pickup and delivery — liftgate, residential delivery, inside delivery, address correction, declared value, reweigh, peak surcharge. Without contract-level controls and Bill of Lading (BOL) authorization, accessorials are the single biggest leakage on a typical invoice. Your first audit with Eller is free.

The accessorials carriers bill most often

The nine charges below cover the bulk of what shows up under "accessorials" on a Less-than-Truckload (LTL) invoice. Dollar ranges are typical national-carrier 2026 numbers; your contracted rates may be lower, and that is exactly what the audit checks. The ranges also vary by lane and by carrier — a national LTL carrier and a regional LTL carrier billing the same liftgate at delivery can be $40 apart for the identical service, and your master agreement should pin down which number applies on your account.

Two notes on reading the table. First, the "typical dollar range" column reflects published tariffs; contracted rates almost always come in lower, sometimes by 30 to 60 percent. Second, the "common dispute trigger" column is the failure mode we see most often on real invoices, not a theoretical edge case — each one shows up in the audit queue weekly.

How accessorials get on your bill (and where it goes wrong)

After several thousand LTL audits, the pattern is consistent: accessorials are where 30 to 50 percent of recoverable money lives. Not the headline rate. Four trigger paths put an accessorial on the invoice, and each one fails differently.

• Driver-discretionary. The driver decides at the dock that a liftgate is needed and codes it on the delivery receipt. If the BOL did not authorize liftgate, the shipper is paying for a unilateral driver call.
• Customer-side request. The consignee asks the driver for inside delivery. The driver performs the service, and the bill flows to the shipper — even though the shipper never agreed to it.
• Carrier-side reclassification. The carrier's address database flags the destination as residential or limited access. The shipper sees a surcharge on a delivery they considered commercial.
• Time-based. Detention starts after a contracted free window (commonly two hours for LTL pickup or delivery). Peak surcharge applies during named seasonal windows. Both depend on accurate clocks and dates that rarely get checked at invoice time.

Worked example: $100M annual program, $1.2M–$2.2M recoverable accessorial leakage per year

A national manufacturer running a $100M annual freight + parcel program. Accessorials typically run 8–12% of total transportation spend at enterprise scale — call it $10M per year billed as accessorial line items on this account.

Audit identifies three categories of recoverable accessorial leakage:

• Driver-discretionary accessorials billed without BOL authorization (liftgate, inside delivery, residential) — typically 4–6% of total accessorial dollars on shippers without strict BOL discipline: $400K–$600K of annual exposure.
• Accessorial stacking — fuel surcharge applied to accessorials in violation of contract exemption clauses, residential + DAS billed where one should override the other, peak surcharge double-counted: $280K–$420K of annual exposure.
• Carrier-classification disputes — commercial addresses billed as residential, limited-access fees billed without site-classification basis, address-correction fees billed against carrier-side typos: $320K–$580K of annual exposure.

Total recoverable accessorial leakage: $1.0M–$1.6M per year on this $100M-scale program. Most shippers leave 60%+ of this on the table without active accessorial audit discipline.

For Fortune 500 shippers running $500M+ annually, the same accessorial leakage profile compounds to $5M–$10M of recoverable accessorials per year. AFS Logistics specifically markets this category as one of its highest-recovery audit segments.

What your contract should say about accessorials

The Master Rate Agreement (MRA) is where accessorial leakage gets prevented — or enabled. Three clause patterns close the most common gaps. None of these are exotic; carriers see them routinely from sophisticated shippers and agree to them often.

Authorization clause

"Accessorial charges shall only apply when (a) checked on the BOL by shipper or (b) authorized in writing by shipper's designated representative prior to driver execution." This kills driver-discretionary liftgate, driver-discretionary inside delivery, and consignee-side requests in a single sentence.

Documentation clause

"Carrier shall provide documentary evidence (driver photo, scale ticket, time stamp) for any accessorial billed in excess of $50." This puts the proof burden on the carrier where it belongs. If they cannot produce the scale ticket, the reweigh comes off.

Cap clause

"Aggregate accessorial charges shall not exceed 15% of base linehaul on any single shipment without prior written approval." This is the backstop. Even when individual accessorials look defensible, a cap stops the pile-on. On the example above, accessorials totaled $221 against $1,420 base — 15.6 percent, which would have triggered a stop-and-review under this clause.

A fourth clause worth adding for parcel-heavy accounts: a peak-window definition tied to the carrier's own published calendar. "Peak surcharges shall apply only during the carrier's then-published peak windows as posted on the carrier's public website at the time the shipment is tendered." That sentence stops the quiet practice of extending peak by an extra week on the back end, which we see on roughly one in every six parcel audits during the December-to-January transition.

Comparison — Authorized vs Discretionary accessorials

The distinction that matters most at audit time is who decided the service was needed. Authorized accessorials are nearly impossible to dispute. Discretionary ones are where the recovery lives.

What we can't tell from the bill alone

Accessorial disputes are a documentation contest. To run one credibly we need three things the invoice does not contain by itself. First, the BOL with its accessorial check-boxes — or a written authorization email if accessorials were added after the BOL was cut. Second, the consignee site classification, which sometimes is only known from a Google Street View check or a quick call to the receiving dock. Third, driver-side evidence: photo of the freight, scale ticket, in-and-out time stamps, signed delivery receipt. Without those three things, "the driver said it was needed" usually wins. With them, the dispute is straightforward.

A practical implication: the audit is faster and the recovery rate is higher when the shipper keeps BOLs in a searchable system rather than as scanned PDFs locked in a TMS attachment field. The single biggest predictor of recovery time on accessorial disputes is how quickly the shipper can produce the original BOL. When the BOL is a one-click pull, the average dispute resolves in 18 to 24 days. When it requires a manual archive search, that same dispute can stretch past 90 days — and carriers sometimes cite their own internal aging window as a reason to deny on procedural grounds.

How Eller Audit handles this

We cross-check every accessorial line against the BOL the shipper actually issued and against the master agreement that governs the lane. When a charge fails either test, we file the dispute with the carrier with the supporting documentation attached. Recoveries flow back to the shipper. Our fee comes out of what we recover — if we find nothing, the audit cost you nothing. The first audit is free either way.

The mechanics on a typical engagement: we ingest the master agreement and the last 90 to 180 days of carrier invoices, normalize the line items against the contracted rate sheet, and flag accessorial deltas that fail authorization, documentation, or cap tests. We hand back a written summary by shipment with the supporting documents attached and a recommended dispute filing for each flagged charge. Approve the ones you want filed; we file them and track them through to credit or refund. Shippers stay in control of the carrier relationship; we do the line-by-line work that nobody on the in-house team has time for.
