Unverifiable Revenue
Start with source records and reconcile them across a consistent period. Bank or payment-processor records, accounting exports, marketplace statements and read-only dashboards can each answer different questions. The goal is not simply to reproduce the seller’s profit number, but to understand how revenue is earned, which costs are necessary to keep earning it, and whether reported performance is repeatable.
Normalize unusual items carefully. Owner add-backs, one-time costs, discretionary expenses and recent changes can be legitimate adjustments, but every adjustment should have a reason and supporting evidence. Compare monthly trends, look for seasonality and identify revenue or cost items that changed shortly before the sale process.
Translate findings into the deal. If an important number cannot be verified, model a conservative case rather than assuming the best outcome. Material uncertainty can justify additional diligence, a different price, a holdback or another structure appropriate to the transaction.
Sudden Performance Spikes
Define what this step is meant to prove before collecting documents. Good diligence connects a claim to evidence, identifies what remains uncertain and asks whether the issue can materially affect future cash flow or transferability.
Compare the current state with historical patterns. One month or one screenshot rarely tells the full story. Look for trends, exceptions and dependencies, then ask the seller to explain material changes with evidence that can be independently checked where practical.
Record the conclusion and its effect on the deal. Some findings simply confirm the thesis; others change valuation, transition planning or transaction terms. The purpose is a better-informed decision, not paperwork for its own sake.
Single-Channel Dependence
Review the acquisition engine at channel level rather than relying on total sessions or users. Separate organic search, paid media, direct, referral, email, social and marketplace traffic, then compare their trends over time. A business with several durable channels has a different risk profile from one whose economics depend on a single ranking, ad account or marketplace.
Ask for source access where practical and inspect the pages, campaigns, keywords or products producing the result. Look for sudden changes, tracking gaps, branded versus non-branded demand, paid spend required to sustain revenue and geographic or device concentration. For search-driven sites, examine whether a small number of pages or queries carry a disproportionate share of traffic.
The buyer’s question is transferability: will these acquisition channels still function under new ownership? Document accounts, permissions, creative assets, tracking, historical data and relationships that must transfer. If a channel depends heavily on the seller’s identity or a non-transferable account, value it accordingly.
Heavy Owner Dependence
A red flag is a prompt for investigation, not automatically a reason to abandon a transaction. First determine the size of the exposure, how long it has existed, whether it is worsening and what evidence would reduce uncertainty. Concentration in a customer, supplier, traffic source, platform or owner can be manageable when it is understood and priced.
Stress-test the business with a downside case. Ask what happens to cash flow if the largest customer leaves, rankings fall, advertising costs rise, a supplier changes terms or the seller stops performing a key task. This turns a vague concern into an operating and valuation question.
Use the result to shape the transaction. Depending on the facts, a buyer may seek a lower price, transition support, representations, a holdback, seller financing or simply decide the risk sits outside the acquisition thesis. Material legal or financial risks deserve professional review.
Weak Asset Ownership
Create an explicit asset schedule instead of assuming that everything used by the business is included. Domains, repositories, source code, content, trademarks, customer data, analytics properties, ad accounts, email lists, social profiles, supplier relationships, licenses and software subscriptions can have different owners and transfer rules.
Confirm control and transferability before closing. Check registrants, account administrators, contractor agreements and relevant license terms. Where an asset cannot transfer directly, identify the replacement process, cost and downtime risk. Credentials should be transferred through a controlled handover rather than informally shared in advance.
Plan acceptance tests for important assets. After transfer, confirm that domains resolve, applications run, analytics collect data, payment flows work and the buyer has administrative control. The purchase agreement and closing checklist should reflect assets that are genuinely critical to continued operation.
Unclear Add-Backs

Seller Pressure
Preparation should make the business understandable without the owner narrating every detail. Reconcile financial records, document recurring work, list important accounts and contracts, confirm ownership of digital assets and explain material dependencies. Buyers can move faster when evidence is organized before diligence begins.
Present strengths and risks accurately. A credible listing explains the business model, historical performance, owner workload, acquisition channels and what is included in the sale. Avoid unsupported projections or hiding a dependency that a buyer is likely to discover later.
Plan the handover while preparing the sale. Document which accounts transfer, which require new accounts, who introduces suppliers or contractors, how long transition support lasts and what the buyer should verify immediately after closing. A smoother transfer can be part of the value proposition.
