Due Diligence for Buying a Storage & Warehousing Business

A structured checklist for evaluating contracts, real estate, equipment, and technology before acquiring a lower middle market warehouse or 3PL operation.

Find Storage & Warehousing Acquisition Targets

Acquiring a storage and warehousing business requires evaluating three interdependent assets: the operating company, the physical facility, and the customer relationships. Buyers must assess lease or ownership structure, customer contract duration, facility condition, and WMS capabilities to accurately price risk and structure a defensible offer.

Storage & Warehousing Due Diligence Phases

01

Phase 1: Financial & Contract Review

Validate revenue quality, customer concentration, and contractual protection before advancing to site visits or lender engagement.

Analyze revenue by customer accountcritical

Request trailing 36 months of revenue broken down by client. Flag any single customer exceeding 30% of total revenue as a concentration risk requiring contract-level protection.

Review all storage and service agreementscritical

Confirm contract length, auto-renewal terms, termination notice periods, and rate escalation clauses across the top 10 accounts by revenue contribution.

Normalize EBITDA for owner compensationcritical

Recast financials to remove above-market owner salary, personal expenses, and one-time costs. Confirm adjusted EBITDA supports the acquisition multiple and debt service coverage.

02

Phase 2: Real Estate & Facility Assessment

Evaluate the physical asset, ownership structure, and environmental status to confirm the facility supports both current operations and future growth.

Confirm real estate ownership or lease termscritical

Determine whether real estate is included in the transaction. If leased, verify remaining term, renewal options, NNN structure, and landlord consent requirements for a change of ownership.

Conduct Phase I environmental assessmentcritical

Order a Phase I ESA before closing on any industrial property. Prior tenant activity, fuel storage, or chemical handling can create inherited environmental liability that affects lender approval.

Inspect facility infrastructure and deferred capeximportant

Assess roof condition, dock levelers, fire suppression systems, racking integrity, and clear height. Deferred maintenance on any of these items must be priced into the offer or seller credit.

03

Phase 3: Operations & Technology Review

Assess workforce stability, technology infrastructure, and operational independence to confirm the business can perform without the selling owner post-close.

Evaluate warehouse management system capabilitiesimportant

Confirm whether the WMS tracks inventory in real time, integrates with customer ERPs, and supports billing automation. Outdated or manual systems represent both a risk and a post-close investment.

Review labor structure and workforce stabilityimportant

Analyze headcount, turnover rates, wage levels, and any union exposure. Identify whether key supervisors or forklift operators are tied to the seller's personal relationships.

Assess owner dependency and management depthcritical

Determine which operational decisions require the owner's direct involvement. Businesses where the owner manages all customer relationships and vendor contracts carry higher transition risk.

Storage & Warehousing-Specific Due Diligence Items

  • Verify facility clear height meets minimum 24-foot standard required for double-deep pallet racking and modern storage density configurations.
  • Confirm occupancy rate trends over 36 months and assess whether waitlist demand or local supply constraints support future rate increases.
  • Request all racking inspection reports and forklift certification records to confirm OSHA compliance and identify any unreported structural damage.
  • Evaluate cold storage or specialized handling certifications if applicable, including temperature logging systems, FDA compliance history, and equipment maintenance contracts.
  • Assess proximity to major highway corridors, rail access, or port infrastructure, which directly affects customer stickiness and limits competitive displacement.

Frequently Asked Questions

What EBITDA multiple should I expect to pay for a warehousing business?

Lower middle market storage and warehousing businesses typically trade at 3.5x to 5.5x adjusted EBITDA. Real estate inclusion, customer contract length, and occupancy rates above 85% push valuations toward the higher end of that range.

Can I use an SBA loan to buy a warehouse business?

Yes. SBA 7(a) and 504 loans are commonly used in these acquisitions. The 504 program is especially effective when real estate is included, allowing buyers to finance 80–90% of the combined business and property value.

How do I evaluate customer concentration risk in a warehousing acquisition?

Request a full revenue-by-account breakdown for the past three years. Any single customer above 30–40% of revenue is a red flag unless protected by a long-term contract with termination penalties and documented renewal history.

What is the biggest due diligence mistake buyers make in warehouse acquisitions?

Underestimating deferred capital expenditures. Roof systems, dock equipment, fire suppression, and racking all have finite lifespans. Buyers who skip a detailed facility inspection often inherit six-figure capex obligations within 24 months of closing.
