Before buying a third-party logistics or freight brokerage business, verify revenue quality, carrier network depth, technology infrastructure, and customer contract stability with this targeted checklist.
Acquiring a lower middle market 3PL or freight brokerage business requires diligence that goes well beyond standard financial review. The most common value destroyers in logistics acquisitions are customer concentration, owner-dependent carrier relationships, and revenue that appears recurring but is actually transactional spot freight. This checklist guides buyers through five critical diligence areas — financial quality, customer contracts, carrier network, technology infrastructure, and people risk — so you can accurately price the business, structure appropriate deal protections, and plan for a successful ownership transition.
Verify true EBITDA, normalize owner compensation, and distinguish durable contract revenue from volatile spot freight volume before accepting any valuation.
Request 3 years of accrual-basis P&L statements and reconcile to tax returns.
Cash-basis or inconsistent financials make EBITDA normalization unreliable and can overstate earnings.
Red flag: Tax returns show materially lower income than seller-presented financials with no clear explanation.
Break down gross revenue by contract freight, managed transportation, and spot brokerage.
Spot freight revenue is volatile and shouldn't be valued at the same multiple as contracted revenue.
Red flag: More than 50% of revenue comes from spot freight with no contracts supporting it.
Identify and document all owner add-backs including personal expenses and above-market salary.
Commingled expenses inflate reported EBITDA and create post-close surprises if not properly normalized.
Red flag: Add-backs exceed 25% of stated EBITDA or lack supporting invoices and documentation.
Review accounts receivable aging and days sales outstanding trends over 24 months.
Deteriorating DSO can signal customer financial stress or billing disputes affecting cash flow.
Red flag: AR aging shows more than 15% of receivables past 60 days or a single customer dominates aging.
Assess how revenue is distributed across the customer base, review all contract terms, and evaluate renewal history to gauge post-acquisition revenue stability.
Build a customer concentration report showing revenue percentage for each of the top 10 accounts.
A single client over 25% of revenue creates significant post-close fragility and lender risk.
Red flag: One customer represents more than 35% of revenue with no long-term contract in place.
Review all customer contracts for term length, auto-renewal clauses, and termination provisions.
Contracts with short terms or easy exit clauses provide little protection against post-close churn.
Red flag: Top customers are on month-to-month agreements or have 30-day termination-for-convenience clauses.
Request customer retention data and churn history for the past 3 years by account and revenue.
High annual retention rates above 90% validate contract stickiness and recurring revenue claims.
Red flag: Two or more top-10 customers have been lost in the past 24 months with no replacement revenue.
Confirm whether key customer relationships are managed by the owner or by account managers.
Owner-held relationships create key-person risk that can accelerate churn at ownership transition.
Red flag: Owner is the primary contact for all three top customers with no account manager layer in place.
Evaluate the depth, exclusivity, and transferability of carrier relationships that underpin service delivery and pricing competitiveness in the 3PL model.
Request a carrier network summary listing top 20 carriers by volume, rates, and relationship tenure.
Carrier depth and preferential capacity access are core competitive assets in a 3PL acquisition.
Red flag: More than 40% of freight volume moves through a single carrier without a formal agreement.
Confirm whether carrier rate agreements and capacity commitments are documented and assignable.
Undocumented carrier relationships may not survive ownership transfer, disrupting service delivery.
Red flag: Key carrier relationships are verbal or personally held by the owner with no written agreements.
Review any dedicated lane agreements, capacity guarantees, or shipper-of-choice status designations.
Preferred capacity arrangements protect margins during tight freight markets and differentiate the business.
Red flag: No documented preferred status exists; carrier capacity is sourced entirely on the open spot market.
Assess geographic coverage, modal capabilities, and any niche vertical specializations such as hazmat or cold chain.
Vertical specialization creates defensible competitive positioning that generalist brokers cannot easily replicate.
Red flag: Business lacks differentiation in any niche and competes purely on price in commodity brokerage lanes.
Evaluate the TMS, WMS, and EDI systems that power operations, assess integration depth with key customers, and estimate the cost and risk of any required upgrades.
Document the current TMS platform, licensing model, and all customer or carrier API integrations.
Modern cloud-based TMS with integrations creates switching costs and scalability; legacy systems do not.
Red flag: Operations run on spreadsheets or a legacy on-premise TMS with no customer EDI integrations.
Review all EDI connections with shipper customers and confirm whether they are owned or broker-dependent.
EDI connectivity with major shippers significantly increases customer stickiness and renewal rates.
Red flag: No EDI connections exist and customers can replace the 3PL without technology switching costs.
Assess WMS capabilities if warehousing or fulfillment services are included in the business model.
Outdated WMS increases labor costs and limits scalability of warehouse and distribution operations.
Red flag: Warehouse operations use manual paper-based processes with no WMS or inventory tracking system.
Estimate total cost of technology migration, upgrade, or replacement needed within 24 months of closing.
Technology upgrade costs must be factored into purchase price and post-close capital planning.
Red flag: Required TMS or WMS replacement will cost more than 20% of annual EBITDA in year one post-close.
Identify critical operational staff, assess retention risk, and evaluate whether the business can run independently of the founding owner after a transition period.
Review the organizational chart and identify all employees managing customer accounts, dispatching, and carrier relationships.
Losing a key dispatcher or account manager post-close can disrupt customer service and carrier coverage.
Red flag: One or two employees other than the owner hold all carrier relationships with no documented succession.
Review employment agreements, non-solicitation clauses, and compensation structures for key operations staff.
Employees without non-solicitation agreements can leave and take customer or carrier relationships with them.
Red flag: No non-solicitation agreements exist for account managers or dispatchers with direct customer contact.
Assess whether the seller is willing to sign a transition consulting agreement of 6–12 months post-close.
A structured transition period reduces relationship transfer risk with key customers and carriers.
Red flag: Seller refuses a meaningful transition period or insists on exiting within 30 days of closing.
Interview operations staff independently to gauge morale, tenure stability, and awareness of the sale process.
Undisclosed employee dissatisfaction or awareness of the sale can trigger departures at or before closing.
Red flag: Multiple key employees are already aware of the sale and have expressed intentions to evaluate other opportunities.

Vetted targets with diligence packages — skip the cold search.
Customer concentration combined with owner-dependent relationships is the most common deal-killer. If one or two customers represent 40% or more of revenue and the founder is their primary contact, post-close churn risk is high. Always verify contract terms, renewal history, and whether account managers — not just the owner — have established relationships with top accounts.
Request a detailed revenue breakdown by service line and customer going back 3 years. Ask the seller to classify each revenue stream as contracted, managed transportation, or spot brokerage. Contracted and managed revenue backed by signed agreements with renewal clauses is far more durable than spot freight volume, which can evaporate in soft freight markets. Discount spot-heavy revenue streams in your EBITDA multiple.
Legacy or on-premise TMS platforms with no customer API or EDI integrations are a major concern. These systems are costly to replace and reduce post-close scalability. Also watch for warehouse operations run on paper or spreadsheets with no WMS. Budget technology upgrade costs into your acquisition model — required replacements within 24 months can meaningfully compress true post-close EBITDA.
Tie the earnout to revenue retention from named top customers over a 12–24 month post-close period. For example, structure 50% of any seller earnout to pay out only if the top 5 customers remain active and meet a defined revenue threshold. This aligns seller incentives with a clean customer transition and protects you against the most common value destruction scenario — key customer departure shortly after closing.
