Operational Due Diligence Checklist for Buyers and Investors

Quick answer: Operational due diligence tests whether the business described in a transaction can deliver its revenue, margin, quality and growth expectations with the available facilities, people, systems, controls and capital. It should identify what the buyer is truly acquiring, what could interrupt performance and what must be rebuilt or funded after closing.

This checklist frames the major operating workstreams. It complements legal, financial, tax, accounting, cybersecurity, environmental, regulatory and other specialist diligence. It does not reproduce CannaShark's engagement-level evaluation or materiality methods.

Eight operational diligence workstreams

Start with the transaction thesis

The review should test the reason the buyer or investor is considering the transaction. A platform acquisition, capacity addition, turnaround, geographic expansion, product extension and management investment create different operating questions.

• What value is the transaction expected to create?
• Which assumptions must be true for that value to exist?
• What capabilities, assets, relationships or licenses are essential?
• What work and capital will be required after closing?
• Which findings could change price, structure, timing or the decision itself?

1. Connect commercial claims to operating evidence

Revenue should be traceable to customers, contracts, products, channels, price, volume, returns and retention. Then test whether the operating system can support the claimed demand and growth.

• Reconcile reported revenue with customer and transaction-level evidence.
• Explain concentration, churn, discounts, credits and unusual sales periods.
• Identify which relationships depend on the owner or a small number of employees.
• Compare forecast demand with realistic capacity and working-capital requirements.
• Separate verified backlog or contracts from pipeline and management estimates.

2. Test margin quality and cash consequences

Reported gross margin may not capture the complete cost of delivery. Examine labor, overtime, scrap, rework, quality holds, freight, commissions, returns, warranty, inventory adjustments and overhead assumptions.

Growth can improve reported revenue while increasing cash pressure. Map purchasing, production, inventory, collection and payment timing to the transaction model.

3. Validate capacity and capital needs

Headline equipment rates and square footage rarely establish usable capacity. Test the complete process under realistic downtime, maintenance, changeovers, labor, quality, storage and product-mix conditions.

4. Identify owner and key-person dependency

A company may appear profitable while relying on undocumented knowledge, personal relationships and routine intervention from one individual. Determine what will remain after that person changes roles or leaves.

The guide on reducing owner dependency outlines the major knowledge, decision, relationship and execution risks to examine.

5. Compare written controls with actual work

Policies show intended behavior. Diligence should test whether employees can perform the work as written, whether required records exist and how management responds when results fall outside expectations.

• Walk material processes from source input to final record.
• Sample evidence rather than relying only on policy documents.
• Identify informal workarounds and the reasons employees use them.
• Review significant incidents, complaints, corrective actions and unresolved exceptions.
• Determine whether controls can operate at the forecast scale.

6. Evaluate systems and management information

Buyers need to know whether reports can be reproduced, definitions are consistent and source systems preserve reliable evidence. Identify manual reconciliations, fragile integrations, unmanaged spreadsheets, access dependencies and reporting that depends on one employee.

7. Test supply and continuity risks

Review supplier concentration, purchasing terms, lead times, minimum orders, quality history, alternates and inventory policies. A low-cost supplier may create material continuity risk if qualification, freight, availability or replacement timing is poorly understood.

8. Build the post-close operating plan

Good diligence does not end with a risk list. Translate the findings into pre-close conditions, Day 1 controls, first-30-day decisions, capital priorities, leadership needs and a realistic integration sequence.

The 90-Day Business Execution Roadmap guide explains how to connect findings to owners, milestones, measures and management reviews.

Warning signs that require deeper review

• Forecast growth exceeds demonstrated capacity without a funded operating plan.
• Margins cannot be reconciled by customer, product, service or channel.
• Reported inventory differs across physical, operating and accounting records.
• Critical customer or supplier relationships are informal or owner-dependent.
• Procedures and systems do not match the workflow employees actually use.
• Deferred maintenance or capital needs are excluded from the transaction model.
• Management reporting depends on manual intervention from one person.
• The integration plan assumes immediate synergies without assigned owners or dependencies.

How CannaShark supports operational diligence

CannaShark helps buyers, sellers, investors and transaction teams connect the deal narrative to operating reality. Depending on scope, the review may draw from strategy, economics, operations, facilities, products, leadership, systems, controls, regulated-industry requirements and post-close execution.

The CannaShark engagement journey

1. Business Evaluation Call: discuss the transaction, decision, available information and whether the paid Diagnostic is the right next step.
2. Paid Business Performance Diagnostic™: examine the agreed business system and identify material constraints, evidence, assumptions and dependencies.
3. Integrated deliverable and presentation: provide one package containing written findings and a prioritized 90-Day Roadmap, followed by a presentation to leadership or the transaction team.
4. Execution choice: Self-Execute, use Guided 90-Day Execution, or select an Embedded 90-Day Buildout where appropriate.

A typical Diagnostic takes approximately 1–3 weeks for a smaller company and 2–4 weeks for a larger company. Very large, highly complex or multi-entity organizations may require additional time. Transaction timing and scope are confirmed based on the decision, available diligence period and access to required information.

Frequently asked questions

What is operational due diligence?

Operational due diligence evaluates whether a company's people, processes, facilities, systems, controls and supply chain can support its historical performance, transaction claims and post-close plan.

How is operational diligence different from financial diligence?

Financial diligence analyzes financial performance and related evidence. Operational diligence examines the capabilities and conditions that produced the results and what may be required to sustain or improve them. The workstreams should inform one another.

Should sellers conduct operational diligence before going to market?

Seller-side readiness can identify contradictory records, unresolved controls, deferred capital, owner dependency and operating explanations before buyers discover them under transaction pressure.

Does CannaShark replace legal, accounting or tax advisers?
