Before you wire funds, verify the carrier network, FMCSA compliance, customer relationships, and technology stack — the four pillars that determine whether this deal holds its value post-close.
Acquiring an auto transport brokerage means buying relationships, regulatory standing, and operational process — not physical assets. The risk in these deals is almost entirely people-dependent: carrier networks built on personal trust, customer accounts tied to the owner's reputation, and compliance obligations that can sink the business if they lapse post-close. This checklist walks buyers through the five critical due diligence domains — financial performance, carrier network integrity, customer concentration, regulatory compliance, and technology infrastructure — with specific red flags and priority ratings for every item. Use it alongside your M&A advisor and transportation-specialized legal counsel before signing a letter of intent or finalizing SBA financing.
Verify that reported revenue and EBITDA are real, recurring, and transferable — not inflated by one-time loads, owner add-backs, or seasonal anomalies.
Request 3 years of P&L statements and reconcile gross revenue to carrier payouts and net brokerage margin.
Auto transport brokers can inflate top-line revenue; net margin after carrier costs reveals true earnings power.
Red flag: Gross margin below 10% or unexplained swings in carrier cost percentage across months.
Obtain a trailing 12-month load-level revenue report segmented by customer type and shipment origin.
Reveals seasonal dependency and whether revenue is driven by retail, dealer, or corporate accounts.
Red flag: More than 40% of annual revenue concentrated in Q1 or Q4 with no mitigation strategy.
Review owner add-back schedule and verify each personal expense with source documentation.
Commingled expenses are common in owner-operated brokerages and distort true EBITDA.
Red flag: Add-backs exceeding 20% of stated EBITDA or undocumented cash payments to carriers.
Analyze accounts receivable aging and identify any dealer or fleet accounts past 60 days.
Slow-paying dealer accounts can create cash flow gaps that strain post-acquisition operations.
Red flag: More than 15% of AR aged beyond 90 days or write-offs increasing year-over-year.
The carrier roster is the operational backbone of any auto transport brokerage. Verify its depth, reliability, and compliance status before assuming it transfers intact.
Request the full carrier roster with FMCSA authority numbers, insurance certificates, and onboarding dates.
A documented carrier list signals process maturity; undocumented networks evaporate when the owner leaves.
Red flag: Fewer than 200 active carriers or no formal onboarding documentation for carrier vetting.
Verify that top 20 carriers by load volume carry at minimum $1M auto liability and $100K cargo insurance.
Inadequate carrier insurance exposes the broker to direct liability on cargo claims post-close.
Red flag: Any top carrier with lapsed insurance or operating on expired FMCSA authority.
Interview 5–10 active carriers to gauge loyalty to the business versus personal loyalty to the owner.
Carriers who follow the owner — not the brand — represent an invisible attrition risk.
Red flag: Carriers who state they work with the business only because of the owner personally.
Review open and historical cargo claims over trailing 36 months including resolution and cost impact.
Frequent claims signal poor carrier vetting and can indicate hidden liability exposure.
Red flag: Claims rate exceeding 2% of loads or any unresolved claims pending at time of LOI.
Auto transport brokerage revenue is only valuable if it survives ownership transition. Scrutinize every major account for concentration risk and contractual portability.
Map the top 20 customers by revenue and calculate each account's percentage of trailing 12-month gross revenue.
A single account representing over 20% of revenue creates catastrophic downside if it churns post-close.
Red flag: Any single customer exceeding 25% of revenue or top 3 customers exceeding 60% combined.
Review all written agreements with dealer groups, fleet operators, and corporate relocation accounts for assignability.
Non-assignable contracts can evaporate at close if customers must re-consent under new ownership.
Red flag: Key contracts with change-of-control clauses giving customers the right to terminate upon acquisition.
Identify which customer relationships are managed by the owner versus dispatchers or account managers.
Owner-managed accounts without documented contacts are the highest attrition risk post-transition.
Red flag: Owner is primary or sole contact for accounts representing more than 30% of revenue.
Request customer retention data and calculate revenue churn rate over the trailing 3 years.
High churn in auto transport often signals service quality or pricing issues that recur post-close.
Red flag: Annual customer churn exceeding 20% or loss of a major dealer group in the past 18 months.
FMCSA authority, surety bond status, and broker operating history are non-negotiable. A compliance gap can halt operations immediately after close.
Verify active FMCSA Property Broker Authority and confirm no revocation or suspension history on record.
Lapsed or revoked broker authority means the business cannot legally operate — deal-ending by definition.
Red flag: Any prior revocation, active FMCSA complaints, or authority issued less than 3 years ago.
Confirm surety bond (BMC-84) or trust fund (BMC-85) is current at minimum $75,000 and provider is solvent.
The surety bond is a federal operating requirement; lapse triggers automatic authority suspension.
Red flag: Bond issued by a non-standard carrier, pending cancellation, or below the $75K federal minimum.
Pull the FMCSA Licensing and Insurance portal history and review any shipper or carrier complaints on file.
Complaint history signals operational or ethical issues that may surface as post-close liability.
Red flag: More than 2 unresolved complaints or any fraud-related allegations in the broker's operating history.
Confirm the business has not acted as a carrier — only as a broker — to avoid unregistered carrier liability.
Brokers who informally arranged carrier duties may carry undisclosed motor carrier liability.
Red flag: Any evidence of direct cargo handling, driver dispatching beyond brokerage, or carrier authority filings.
The TMS, load board integrations, and CRM are the operational DNA of a modern auto transport brokerage. Assess transferability, scalability, and dependency before close.
Identify the TMS platform in use and confirm whether the license, data, and historical loads transfer at close.
Losing TMS access or historical load data post-close disrupts dispatch, invoicing, and carrier management.
Red flag: TMS is a personal license in the owner's name with no transferability clause or data export capability.
Review all load board subscriptions — Central Dispatch, Super Dispatch, uShip — and confirm transferability.
Load boards are the primary sourcing channel for capacity; interrupted access stalls operations immediately.
Red flag: Accounts tied to personal email or owner identity with no business-level login or admin transfer path.
Assess CRM or customer management system for completeness of contact data, quote history, and account notes.
A well-populated CRM reduces key-person dependency and accelerates buyer relationship continuity.
Red flag: No formal CRM in use — customer contacts stored in owner's personal phone or email.
Evaluate whether dispatch workflows and carrier onboarding processes are documented in written SOPs.
Undocumented processes live in the owner's head and cannot be transitioned on a defined timeline.
Red flag: No written operations manual and owner unable to demonstrate repeatable process without their involvement.
Find Auto Transport Brokerage Businesses For Sale
Vetted targets with diligence packages — skip the cold search.
Request the broker's MC number and pull their full FMCSA licensing and insurance record directly from the FMCSA portal at safer.fmcsa.dot.gov. Confirm the Property Broker Authority is active with no revocation history, verify the surety bond (BMC-84) or trust fund (BMC-85) is current at the $75,000 federal minimum and issued by a rated carrier, and review all shipper and carrier complaints on file. These three items are binary — any material issue is a deal-stopper that no earnout or price reduction can adequately offset because operational authority is required to run the business on day one.
Start by requesting the full carrier roster with FMCSA authority numbers and load volume per carrier over the trailing 12 months. Then conduct direct conversations with the top 10–15 carriers by volume — ask how long they've worked with the business, who they call when they have capacity, and whether they'd continue under new ownership. Carriers who cite the owner by name as their primary reason for loyalty are a transition risk. Look for businesses where dispatchers or account managers have established carrier relationships, formal onboarding documentation exists, and the broker has a reputation — not just a personality — in the carrier community.
Well-documented auto transport brokerages with diversified customer bases, established carrier networks, and EBITDA margins above 15% typically transact in the 2.5x to 4.5x EBITDA range. Businesses closer to the high end have recurring dealer or fleet contracts, a trained dispatch team, and a modern TMS with clean financials. Brokerages with high owner dependency, customer concentration, or unresolved FMCSA issues trade at the low end — or don't trade at all without significant price adjustments. SBA 7(a) financing is widely available for these acquisitions, which supports buyer leverage and keeps equity requirements manageable at 10–15% down.
The large majority of lower middle market auto transport brokerage acquisitions close as asset purchases. This structure lets you acquire the carrier network, customer relationships, TMS data, trade name, and goodwill while leaving behind undisclosed liabilities, pending cargo claims, and historical FMCSA complaints. The key exception is FMCSA broker authority — authority does not transfer in an asset purchase, so you'll need to apply for your own MC number or structure a holding company acquisition carefully with counsel. Most buyers apply for new broker authority in parallel with due diligence so it's active at or near close, often retaining the seller's brand and operating name under the new authority.
