Due Diligence Checklist · Courier & Last-Mile Delivery

Due Diligence Checklist for Buying a Courier & Last-Mile Delivery Business

Before you wire funds on a regional delivery business, verify driver classification compliance, fleet condition, customer contract terms, and DOT safety records — the four areas most likely to destroy value post-close.

Acquiring a courier or last-mile delivery business in the $1M–$5M revenue range offers genuine upside: recurring route revenue, essential-service demand, and strong SBA financing eligibility. But the sector carries hidden risks that standard financial due diligence won't catch. Driver misclassification lawsuits, aging fleets masking deferred capital expenditures, single-customer revenue concentration, and owner-dependent dispatch operations are the most common deal-killers in this space. This checklist walks buyers through every critical area — from CSA safety scores to route density economics — so you can price risk accurately and structure a deal that protects your investment from day one.

Driver Classification & Labor Compliance

Independent contractor misclassification is the single largest legal liability in courier acquisitions. Validate classification status before signing anything.

critical

Request complete IC agreements and W-2 payroll records for all drivers for the past 3 years.

Misclassified drivers expose the buyer to back taxes, penalties, and potential class-action liability worth hundreds of thousands.

Red flag: Driver contracts lack behavioral control provisions or drivers operate exclusively for this business without IC flexibility.

critical

Audit state-level IC compliance in every state where drivers operate, not just the federal ABC test.

California, Massachusetts, and New Jersey apply stricter ABC tests that can invalidate IC status automatically.

Red flag: Seller has never conducted a formal IC audit and operates in a high-risk state like California or New Jersey.

critical

Review any prior DOL audits, state labor board complaints, or litigation related to driver classification.

Past complaints signal systemic misclassification risk and indicate the seller is aware of exposure.

Red flag: Open or settled labor board claims involving driver status within the past 5 years.

important

Confirm workers' compensation coverage structure — IC exclusion policies vs. employee coverage.

A single on-the-job injury from a misclassified IC can trigger reclassification audits across the entire workforce.

Red flag: Workers' comp policy excludes all drivers classified as ICs with no commercial general liability backstop.

Customer Contracts & Revenue Concentration

Recurring route revenue is the core value driver. Confirm contracts are real, transferable, and not dangerously concentrated.

critical

Obtain and review all executed customer contracts including term lengths, renewal clauses, and rate escalation provisions.

Verbal agreements or month-to-month arrangements can evaporate immediately after ownership transfer.

Red flag: More than 40% of revenue operates on verbal agreements or purchase orders with no signed contract.

critical

Calculate revenue concentration — identify every customer exceeding 15% of total annual revenue.

Single-customer dependency above 30% creates catastrophic downside if that account is lost post-close.

Red flag: One customer represents more than 30% of revenue with a contract expiring within 12 months of close.

important

Confirm all customer contracts contain assignment clauses permitting transfer to a new owner.

Non-assignable contracts may require customer consent, which gives accounts leverage to renegotiate or exit.

Red flag: Key contracts are silent on assignment or explicitly require customer approval with no consent secured.

important

Review 3-year customer retention data and identify any accounts lost in the prior 24 months.

Churn history reveals service quality issues and competitive vulnerability invisible in current revenue figures.

Red flag: More than two significant accounts lost in the past 24 months with no documented replacement pipeline.

Fleet Condition & Capital Expenditure Requirements

Fleet is the backbone of any delivery operation. Deferred maintenance and aging vehicles are the most common source of post-close surprises.

critical

Obtain titles, registration, current mileage, and full maintenance logs for every vehicle in the fleet.

Incomplete records signal deferred maintenance and make accurate replacement cost projections impossible.

Red flag: More than 30% of vehicles lack organized maintenance logs or are operating beyond manufacturer service intervals.

critical

Commission independent mechanical inspections on all vehicles over 100,000 miles or 5 years old.

Seller-provided condition assessments are unreliable; independent inspections reveal actual replacement timelines and costs.

Red flag: Seller refuses third-party fleet inspection or significant deferred repairs surface during independent review.

important

Build a 3-year fleet replacement pro forma based on mileage, age, and current commercial vehicle prices.

Capital expenditure requirements can erode EBITDA by 20–40% if not modeled accurately into your purchase price.

Red flag: Fleet average age exceeds 7 years with no planned replacement budget documented by the seller.

important

Verify commercial auto insurance history including claims frequency, at-fault accidents, and current premium levels.

High claims frequency increases premiums and signals driver quality issues that raise ongoing operating costs.

Red flag: Three or more at-fault accidents in the past 3 years or insurance carrier non-renewal in the past 24 months.

DOT Compliance & Safety Record

A clean DOT record is non-negotiable. Compliance violations can suspend operations, void insurance, and trigger regulatory investigations post-close.

critical

Pull the company's FMCSA SAFER system profile and review all CSA scores across the seven behavioral categories.

CSA scores above intervention thresholds can trigger targeted roadside inspections and operational restrictions.

Red flag: Any CSA category score in the top 25% alert threshold or an active FMCSA compliance investigation.

critical

Review all roadside inspection reports, out-of-service orders, and compliance review outcomes for the past 3 years.

Patterns of violations reveal systemic fleet maintenance or driver management failures, not isolated incidents.

Red flag: Out-of-service rate exceeding the national average or a prior unsatisfactory compliance review rating.

important

Verify all driver qualification files including CDL status, MVR records, medical certificates, and drug test documentation.

Missing or expired driver qualification files create immediate FMCSA liability and can void commercial insurance coverage.

Red flag: Driver files are incomplete, expired medical certificates exist, or pre-employment drug testing records are missing.

standard

Confirm USDOT and MC numbers, operating authority status, and that all required permits are current and transferable.

Lapses in operating authority or non-transferable permits can halt operations immediately after ownership change.

Red flag: Operating authority is inactive, under review, or MC number carries an unsatisfactory safety rating.

Operations, Owner Dependency & Transition Risk

Route density and route economics only matter if the business can operate without the seller. Assess management depth before you close.

critical

Document who manages dispatch, driver scheduling, and customer communication on a daily basis.

Owner-dependent dispatch with no backup creates immediate operational failure risk on day one of ownership.

Red flag: Seller personally handles all dispatch and customer calls with no documented backup or deputy in place.

critical

Obtain all documented SOPs for dispatch, driver onboarding, customer complaint resolution, and route optimization.

Undocumented operations cannot be transferred — what lives in the seller's head dies when the seller leaves.

Red flag: No written SOPs exist for any core operational function; business runs entirely on owner tribal knowledge.

important

Evaluate route density metrics — stops per hour, revenue per route mile, and geographic coverage map.

Route density determines true profitability; sparse routes signal competitive vulnerability and higher cost per delivery.

Red flag: Revenue per route mile has declined more than 10% year-over-year or route density is concentrated in one zip cluster.

standard

Assess the technology stack — TMS platform, route optimization software, dispatch tools, and customer reporting systems.

Manual dispatch operations limit scalability and create bottlenecks that depress margins as volume grows.

Red flag: Business operates on spreadsheets and phone calls with no route optimization or fleet tracking software in place.

Frequently Asked Questions

How do I assess driver misclassification risk when buying a courier business?

Start by obtaining all IC agreements and running them against the ABC test criteria in each state where drivers operate — not just federal standards. Review DOL audit history, workers' comp policy exclusions, and whether drivers work exclusively for this company. Engage an employment attorney specializing in logistics labor compliance before you sign a letter of intent. If reclassification risk is material, price it into the deal via an escrow holdback or seller indemnification clause covering at least 24 months post-close.

What is a reasonable customer concentration threshold for a courier acquisition?

Most experienced buyers and SBA lenders treat 30% as the single-customer concentration ceiling. Above that level, you should demand an earnout structure tying a portion of the purchase price to that customer's contract renewal and revenue retention for at least 12 months post-close. Ideally, no single customer exceeds 25% of revenue, and the top five customers collectively represent no more than 70% of total revenue. Always verify contracts are signed, current, and contain assignment provisions before accepting any concentration as acceptable.

Can I use an SBA 7(a) loan to buy a last-mile delivery business?

Yes — courier and last-mile delivery businesses are among the more SBA-eligible acquisition targets in the transportation sector, provided the business meets standard SBA eligibility requirements. Lenders will typically require a minimum $300K–$500K in adjusted EBITDA, 10–15% buyer equity injection, and clean DOT compliance history. The asset-heavy nature of fleet-based businesses can complicate collateral coverage, which is why sellers are often asked to carry a 5–10% seller note to fill any collateral gap and demonstrate confidence in the business's post-close performance.

How do I evaluate whether a courier business's fleet is fairly priced into the deal?

Build a fleet replacement pro forma that models each vehicle's current market value, remaining useful life based on mileage and age, and current commercial vehicle replacement costs. Commission independent mechanical inspections on any vehicle with more than 100,000 miles or over five years old before finalizing your valuation. If the seller's asking price assumes zero near-term capex but your inspection reveals $150K–$300K in deferred maintenance or imminent replacements, that gap should directly reduce your offer price or be funded via a post-close capex reserve negotiated at closing.
