UPDATED AUGUST 2026
Across the heavy truck industry, 2026 is shaping up as a stress test, not a reset for dealership finance and fixed operations leaders.
The April 2026 ATD Truck Beat reports commercial truck sales down 17.7% year-over-year in Q1 2026, with heavy-duty off 20.5%. This is the ninth straight month of year-over-year declines. But Class 8 orders in March jumped more than 100% year-over-year, and ATD revised its 2026 heavy-duty forecast up 31% from its January estimate. The demand side is turning, but cost pressure isn’t.
Section 232 tariffs of 25% on imported medium- and heavy-duty trucks and parts remain in force. USMCA content procedures published in February 2026 offer partial relief on qualifying vehicles, but only for the U.S. content portion. The documentation burden is real, and tariff-related line items keep landing on parts invoices.
That's the paradox of 2026: a market waking up while cost pressure holds. Controllers are answering harder margin questions with the same team. AP is working invoices with more line items and less certainty about what's legitimate. CFOs are watching cash while planning for a recovery that's real but uneven.
In this context, 2026 tests how well heavy truck dealers understand their costs, protect parts margin, and manage cash. External forces cannot be controlled, but the quality of data and decisions inside the dealership can.
A few macro trends frame the decisions dealers face.
Freight and truck demand: hitting bottom, then snapping back
Commercial truck sales spent 2024 and 2025 in freight-recession territory, and Q1 2026 marked the low point. Heavy-duty sales were down 20.5% year-over-year in the first quarter, capping the ninth straight month of declines.
The order side is pointing the other direction. North American Class 8 net orders in March 2026 reached about 37,200 units, up 126% year-over-year, the second straight month of triple-digit gains. ATD revised its 2026 heavy-duty sales forecast up 31% from its January estimate, to 225,000 units.
For dealers, the practical read is that unit sales are stabilizing, but the last several quarters have reshaped fleet behavior. Trucks are staying in service longer. Fleets are buying selectively and protecting cash. Fixed operations, parts and service, are carrying more of the load, which puts pressure on the exact functions where tariff costs land hardest.
Tariffs: cost pressure that keeps evolving
The Section 232 action from October 2025 remains in force. Class 3 through 8 medium- and heavy-duty trucks and truck parts face a 25% ad valorem duty, buses face 10%, and used or remanufactured vehicles under 25 years old are covered.
The tariff picture is more nuanced than it was at launch. In February 2026, the Department of Commerce published procedures allowing importers of USMCA-qualifying medium- and heavy-duty vehicles to apply for reduced duty. The 25% tariff applies only to the non-U.S. content portion of qualifying vehicles.
For dealers, this means the tariff line on an invoice isn't always final. Some vehicles qualify for reduced duty if the importer went through the Commerce approval process. Others don't. The result is more variability in landed cost per vehicle, and more work at the invoice level to catch what applies where.
CFO sentiment: higher costs, cautious investment
Broader CFO sentiment reflects the same reality. According to the Q2 2026 CFO Survey from Duke's Fuqua School of Business and the Federal Reserve Banks of Richmond and Atlanta, price growth in 2026 would be roughly 25% lower without tariffs. Tariffs and trade policy have now ranked as the top CFO concern for five consecutive quarters. Finance leaders are delaying capital projects, prioritizing productivity, and paying closer attention to working capital.
Heavy truck dealerships reflect that reality. Budgets are tighter, new investments receive more scrutiny, and finance teams are expected to do more with the same headcount. Those macro forces show up quickly at the parts counter, in the service bay, and inside accounts payable.
Those headline trends translate into specific pressures on parts, service, and accounts payable.
Parts: cost creep and relationship pressure
Tariffs and inflation appear on parts invoices as:
Parts managers must protect gross profit while preserving long-standing customer relationships.
Experiences during the chip shortage offered a preview. When chips were scarce, trucks waited on lots and customers often blamed the dealer. Stores with access to uptime-critical inventory sometimes became suppliers to neighboring dealers, creating a new revenue stream. Control over key parts translated directly into pricing power.
Tariffs are not the same as a shortage event, yet the lesson is similar. Dealers that understand where tariff pressure lands and plan stocking and pricing accordingly are better positioned than those reacting invoice to invoice.
Service: more uptime expectations, less room on the RO
Service departments face more complex repairs on aging equipment and customers who question every line on the repair order.
Service advisors are often the ones sitting with a fleet manager, walking through a repair order and explaining why a part costs more this month than it did last quarter.
To customers, that can sound like dealer markup, even when the underlying cause is a 25% import duty upstream. Clear internal data helps service teams explain price changes in a way that protects trust.
AP and finance: where every pressure converges
All of this activity ultimately flows through accounts payable and finance.
AP teams now work with vendor invoices that blend base cost, tariff and duty lines, fuel and freight surcharges, and discounts or rebates.
The documents behind those invoices (POs, receiving records, vendor contracts) are often scattered across email inboxes, shared drives, SharePoint folders, and DMS screens. Approvals move through informal channels: forwarded emails, phone calls, sticky notes on monitors. Matching takes place across multiple rooftops with limited visibility into landed cost per part, vendor, or branch.
This is where dealership controllers are rebuilding control — trying to answer questions like:
Slow approvals add another drag. Invoices sit in limbo, statements do not clear, finance fees accumulate, and misapplied sales tax builds over time. In a tight margin year, those leaks are increasingly visible. Against that backdrop, finance leaders in heavy truck dealerships benefit from a focused set of steps to regain control.
Protecting margin, cash, and control in this environment doesn't require perfect analytics. It calls for a small set of practical moves that make the picture clearer and decisions easier.
1: Build a clear view of cost and spend trends from the data you already have
A practical first move is to assemble a basic view from data across AP, purchasing, and the DMS that shows:
The ATD Commercial Truck Dealer financial profile provides useful benchmarks for fixed operations performance. Comparing internal trends to industry norms helps dealers see whether they are outliers or tracking with broader market shifts.
The goal is clarity, not perfection. Even a straightforward report can support better decisions about pricing, stocking, and vendor negotiations.

2: Align parts, service, and finance on a pricing stance
Controllers, AP managers, parts managers, and service managers benefit from reviewing the same data and agreeing on a clear stance:
Industry context strengthens those conversations. ATA’s American Trucking Trends notes that trucks moved 11.27 billion tons of freight in 2024, down from 11.41 billion the prior year. That decline underscores the pressure fleets feel and helps frame pricing discussions as a shared response to market conditions rather than a dealer-specific issue.
3: Treat inventory and payables as working capital levers
A third move is to treat inventory and AP as active levers for working capital instead of back-office chores.
When you connect AP, purchasing, and DMS data, dealers can see:
When purchasing and AP teams review the same information, it becomes easier to keep critical parts in stock, free up cash from the wrong inventory, and avoid year-end surprises.
For many dealerships, the harder problem isn't identifying the next steps. It's executing them without more headcount, more time, or more system-jumping across email, DMS screens, and shared drives.
A connected finance and operations platform, one that handles AP automation, document management, workflow, and payments as a single system, is where those moves become executable. This is the argument for consolidating the dealership tech stack rather than adding another point tool.
Turning invoices and documents into data
With a connected platform, AP teams have early visibility into how tariffs, fees, and taxes show up on invoices. When those teams spend most of their time chasing approvals or rekeying data from PDFs, that insight is lost.
With intelligent invoice capture, matching, and rules, AP teams can:
The document layer matters just as much. POs, receiving records, vendor contracts, and remittance advices live in one indexed system instead of shared drives and inboxes, searchable by vendor, rooftop, or SKU. When a fleet manager questions a repair order or an auditor asks for backup, the source document is already attached.
For finance and AP teams working across DMS platforms like Procede, Excede, and CDK, integrations matter:
Approvals and payments that keep moving
Approvals across multi-rooftop dealerships tend to travel through informal channels: forwarded emails, phone calls, sticky notes on monitors. Workflow automation replaces that with routing rules the business already has in its head:
Approvers see everything they need in one place, and the audit trail builds itself.
Payments follow the same logic. Once an invoice is approved, payment goes out through the right rail based on vendor preferences and dealer terms:
Cash timing becomes something the CFO can schedule instead of chase. For one AP specialist's experience of that shift, see how Thompson Trucks moved 3,000 invoices to zero weekends.
Once invoices, documents, approvals, and payments live in one connected system, every transaction becomes a data point. Controllers and AP managers can track:
This is the visibility and discipline that protect margin and cash, the levers dealerships can still control when everything upstream is uncertain.
The 2026 outlook is mixed. Orders are turning, forecasts are being revised up, but cost pressure looks durable. Tariffs, trade policy, and freight market conditions will keep evolving.
Heavy truck dealers cannot afford blind spots under those conditions. Untracked tariff surcharges and freight fees erode parts margin. Misapplied sales tax adds up over hundreds of invoices. Slow, fragmented approvals weaken purchasing power and strain relationships with vendors and fleets.
Dealers that emerge from 2026 in a stronger position will focus on three levers they can influence:
onPhase gives finance and operations teams at heavy truck dealerships one connected system for AP automation, document management, workflow, and payments. Invoice data, documents, approvals, and cash timing all live in one place, giving finance clearer visibility across every rooftop, even as conditions continue to shift.

Heavy Truck Tariff FAQs
What is the Section 232 tariff on heavy trucks?
The Section 232 tariff imposes a 25% ad valorem duty on imported Class 3 through 8 medium- and heavy-duty trucks and truck parts, and 10% on buses. It went into effect November 1, 2025, and remains in force in 2026.
Which trucks are affected by the tariffs?
The tariffs apply to imported Class 3 through Class 8 medium- and heavy-duty trucks and their parts. Class 3 covers light-medium duty (14,001 to 16,000 lbs GVWR), running up through Class 8 (over 33,000 lbs GVWR), which includes most semi-tractors and heavy vocational trucks. All buses, including school buses, city buses, and motor coaches, face a 10% tariff. Used and remanufactured trucks and buses under 25 years old are also covered. Trucks assembled in the U.S., and those that qualify for USMCA preferential treatment with documented U.S. content, may be eligible for reduced duty.
How do USMCA rules affect heavy truck tariffs in 2026?
In February 2026, the Department of Commerce published procedures allowing importers of USMCA-qualifying medium- and heavy-duty vehicles to apply for reduced duty. Once Commerce approves the documentation, the 25% tariff applies only to the non-U.S. content portion of qualifying vehicles.
How have commercial truck sales performed in 2026?
Q1 2026 was the low point. Heavy-duty sales were down 20.5% year-over-year, the ninth straight month of declines. But orders are turning: Class 8 net orders in March jumped 126% YoY, and ATD revised its 2026 heavy-duty forecast up 31% from its January estimate, to 225,000 units.
How do tariffs affect heavy truck dealership finance teams?
Tariffs show up on parts invoices as higher list prices, tariff surcharge lines, and freight fees. AP teams work with invoices that blend base cost, tariffs, freight, discounts, and taxes. Controllers face harder questions about which cost drivers are pressuring parts margin, and slow approvals compound the drag on cash.
How can heavy truck dealerships manage tariff-driven cost pressure?
Three practical moves: build a clear view of cost and spend trends from data across AP, purchasing, and the DMS; align parts, service, and finance on a shared pricing stance; and treat inventory and payables as working capital levers. Executing these consistently depends on AP automation, document management, workflow, and payments working together as one connected system.
