Due Diligence Guide for Acquiring a Third-Party Logistics Business

Know exactly what to verify before buying a 3PL or freight brokerage — from contract revenue quality to carrier network depth and TMS infrastructure.

Find Third-Party Logistics (3PL) Acquisition Targets

Acquiring a lower middle market 3PL requires scrutinizing revenue durability, carrier relationships, and technology infrastructure. Fragmentation creates opportunity, but customer concentration, owner dependency, and spot-freight exposure are common deal risks that diligence must surface before closing.

Third-Party Logistics (3PL) Due Diligence Phases

01

Phase 1: Financial & Revenue Quality Review

Validate EBITDA, normalize owner compensation, and distinguish stable contract revenue from volatile spot freight to assess true earnings power.

Revenue segmentation by contract, managed, and spot freightcritical

Break down trailing 3-year revenue by type. Contract and managed freight signals durability; high spot freight exposure creates unpredictable EBITDA and weak debt service coverage.

Owner add-back normalization and EBITDA verificationcritical

Identify personal expenses, above-market owner salary, and one-time costs commingled in financials. Recast to accrual-basis EBITDA to establish a defensible valuation baseline.

Customer concentration and revenue distribution analysiscritical

Request a revenue-by-customer report for the top 10 accounts. Flag any single client exceeding 20–25% of revenue as a lender and deal-structure risk.

02

Phase 2: Operational & Commercial Diligence

Evaluate carrier network strength, customer contract terms, and key employee dependency to assess operational continuity post-acquisition.

Customer contract review including renewal and termination clausescritical

Obtain all active customer agreements. Verify contract lengths, auto-renewal provisions, SLA penalties, and whether pricing includes carrier rate pass-through mechanisms.

Carrier network depth and relationship documentationimportant

Request a top-20 carrier list with annual volumes, rate agreements, and exclusivity terms. Assess whether relationships are held by the founder or distributed across operations staff.

Key employee retention risk assessmentimportant

Identify account managers, dispatchers, and ops staff with critical carrier or customer relationships. Evaluate compensation, tenure, and whether retention agreements are in place.

03

Phase 3: Technology & Integration Readiness

Assess TMS and WMS infrastructure, EDI integrations, and IT vendor contracts to determine scalability and post-close upgrade costs.

TMS and WMS platform evaluationcritical

Identify the current TMS and WMS vendors, licensing costs, and system age. Outdated or manual platforms signal high post-acquisition IT spend and operational headcount inefficiency.

EDI and API integration auditimportant

Document all active EDI connections and API integrations with shippers and carriers. These integrations create switching costs and sticky revenue; gaps signal scalability risk.

IT vendor contracts and data security reviewstandard

Review SaaS agreements, software licenses, and cybersecurity posture. Confirm contracts are assignable post-close and identify any near-term renewal or upgrade obligations.

04

Phase 4: SBA Financing and Deal Structure Validation

Verify the Third-Party Logistics (3PL) acquisition qualifies for SBA financing, the purchase price is supportable by the verified cash flow, and the deal structure protects the buyer's downside.

SBA Eligibility Confirmationcritical

Confirm the Third-Party Logistics (3PL) meets SBA 7(a) eligibility requirements: the business is for-profit, U.S.-based, within SBA size standards, and the buyer meets personal financial requirements. Some industries have specific SBA restrictions — verify before LOI.

Normalized EBITDA vs. SBA Debt Service Coveragecritical

Model verified normalized EBITDA against projected SBA loan payments at current rates. A $1M SBA 7(a) loan at 10.5% over 10 years costs approximately $13,000/month. The Third-Party Logistics (3PL) must generate at least 1.25x debt service coverage after a market-rate manager salary to pass underwriting.

Seller Note and Earnout Structure Reviewimportant

Confirm the seller note is properly subordinated to the SBA loan and goes on 24-month standby as required by SBA rules. If an earnout is included, define exact measurement metrics, time period, and dispute resolution process before signing the purchase agreement.

Third-Party Logistics (3PL)-Specific Due Diligence Items

  • Request a freight margin report by lane and customer to identify where brokerage spread is healthy versus compressed by carrier rate volatility.
  • Verify broker authority, FMCSA licensing, surety bond status, and any open freight claims or regulatory violations in the FMCSA portal.
  • Assess niche vertical exposure such as temperature-controlled, hazmat, or final-mile — specialization commands higher multiples and deeper carrier loyalty.
  • Confirm whether the TMS has real-time tracking and carrier API connectivity, as shippers increasingly require visibility tools as a baseline service expectation.
  • Evaluate whether customer pricing contracts include fuel surcharge and accessorial pass-through clauses that protect gross margin during carrier rate cycles.
  • Verify that the purchase price divided by verified normalized EBITDA produces a multiple consistent with current market comparables for Third-Party Logistics (3PL) transactions — overpaying by 0.5x–1.0x EBITDA is the most common buyer error in this sector.
  • Confirm the lease terms are assignable to the buyer with the landlord's written consent, and that the remaining lease term extends at least through the SBA loan term — lenders require this before funding.
  • Request copies of all material vendor contracts, supplier agreements, and service relationships — confirm which are transferable, which require novation, and which may terminate on change of ownership.

Standard Document Request List

Before signing a Letter of Intent, request these documents from the seller. Missing or incomplete items are a red flag — not a reason to proceed without them.

  • 3 years of business tax returns (Schedule C or Form 1120)
  • Last 3 years profit & loss statements (monthly detail)
  • Current balance sheet and accounts receivable aging
  • Customer/client list with revenue by account (anonymized)
  • All active contracts, subscriptions, and recurring agreements
  • Equipment list with condition and estimated replacement cost
  • Employee roster with tenure, title, and compensation
  • Any pending or threatened litigation or regulatory complaints
  • Owner compensation and discretionary expense add-backs
  • Year-to-date financials vs. prior year same period

Frequently Asked Questions

What EBITDA multiple should I expect to pay for a lower middle market 3PL?

Expect 3.5x–6x EBITDA. Asset-light freight brokerages with diversified contracts and modern TMS infrastructure command upper-range multiples; commodity spot-freight models trade at the lower end.

Can I use an SBA 7(a) loan to acquire a freight brokerage or 3PL?

Yes. 3PLs are SBA-eligible. Typical structures include 10–15% buyer equity, an SBA 7(a) loan covering the majority, and a seller note of 5–10% to bridge any valuation gap.

How do I evaluate customer concentration risk in a 3PL acquisition?

Request a 3-year revenue-by-customer report. Any single client above 25% of revenue is a risk flag. Prioritize targets with multi-year contracts and demonstrated 90%+ annual customer retention rates.

What is the biggest operational risk when a founder-operator sells a 3PL?

Key-person dependency. Founders often hold all top carrier and customer relationships personally. Require a 12–24 month transition plan, consulting agreement, and retention incentives for second-tier operations staff.
