Commercial and Financial Diligence: What Each Stream Tests

Ask a deal team what CDD and FDD are and you get two workstreams pointed at the same revenue line. Ask the open web and you get a bank onboarding file and a franchise contract. Four meanings, two acronyms, and only two of them belong to a transaction.

Separate them first. Then put the two deal streams side by side at the level a scope of work actually gets written: what each one examines, what evidence it can produce, and where the two have to agree before anybody prices anything.

Four Meanings Behind Two Acronyms

In banking, CDD is customer due diligence. The rule amends Bank Secrecy Act regulations and, in the financial-crime regulator's own words, clarifies and strengthens customer due diligence requirements for banks, mutual funds, brokers or dealers in securities, futures commission merchants and introducing brokers in commodities. It governs whose account a financial institution may open and maintain. It has no bearing on whether a company's customers will still be there next year.

In franchising, FDD is the franchise disclosure document. The trade regulator's Franchise Rule prescribes its contents item by item, and any claims the franchisor makes about sales, income or profits must be in Item 19. Different body of law, different reader, different decision. If your results are about franchising, the question went to the wrong corpus.

In a deal, CDD is commercial due diligence and FDD is financial due diligence. Write the full words into the scope. Acronym collisions are how a question ends up answered by the wrong specialist.

What Financial Diligence Tests in the Numbers

Financial due diligence asks one question in several ways: how much of the earnings on the books survives the transaction. It is not an audit and is not trying to be. Quality of earnings analyses and statutory audits often review similar financial information, but they serve fundamentally different purposes. The audit tests compliance with an accounting framework, looking backwards. The diligence work tests sustainability, looking forwards, at much lower materiality.

The procedures are concrete.

• Proof of cash. Tie earnings to bank movement. If cash cannot be proved, nothing downstream is safe.
• Revenue recognition. Test it against the company's own stated policy and against generally accepted principles, then check that revenues and expenses sit in the right periods.
• The adjustment bridge. Separate what management proposed from what the deal team found on its own. Estimates should not be accepted and the rationale for each adjustment should be challenged, with original documentation behind every add-back.
• Concentration. Customer concentration is standard. Industry, product, distribution channel and supplier concentration move the risk of the same earnings and are skipped more often.

One discipline worth importing from public-market rules: where a filer presents EBITDA as a performance measure, it should be reconciled to net income as presented in the statement of operations under GAAP, and a measure built differently should not carry the name EBITDA at all. A private seller owes you no such reconciliation. Ask for it anyway, and work the quality of earnings from there. A financial diligence checklist is where those requests get sequenced.

What Commercial Diligence Tests in the Market

Commercial due diligence works outside the ledger. Market size and segmentation. Where growth came from and whether that source continues. The competitive set and what it is doing about price. The go-to-market motion. And what customers say when asked by somebody who does not work for the seller. Its evidence is interviews, primary research and public filings, not the general ledger.

The bar has moved. Buyers are now expected to go beyond high-level synergy work and define how cost and revenue synergies will be achieved and when. That is commercial work with dates and owners attached, and it is the part most often left as a line in a spreadsheet with nobody behind it.

The Revenue Line Both Streams Touch

Revenue is where the two overlap, and where they fail differently.

Financial diligence asks whether revenue was recognised correctly and whether it repeats under the current operating model. Commercial diligence asks whether the demand behind it repeats at all: same customers, same willingness to pay, same competitive position. A contract can be accounted for perfectly and still be the last one that customer signs.

So one figure can pass both tests separately and still break the deal. Recurring in the accounting sense is not durable in the market sense. Somebody has to hold the two answers against each other, and by default nobody does. That is the same seam problem that runs through how diligence workstreams divide.

What Each Stream Needs From the Other

• Finance needs the demand view before it labels revenue recurring. A cohort that renews on paper and churns in the market is a normalisation error, not a surprise.
• Commercial needs the normalised earnings base before it sizes the plan. Growth built on an earnings base the adjustment bridge later moves is wasted work.
• Both need the same customer list. One stream's concentration table and the other's interview list should reconcile name for name. Where they do not, ask why.
• Both need the same definition of a one-off. An item management calls non-recurring is a commercial question before it is an accounting one.

Run one request list, not two. A single M&A due diligence checklist and one diligence questionnaire stop the streams asking the seller the same thing twice and getting two different answers.

Reading Both Sets of Findings Before Pricing

Findings do not price a deal. People do, and the discipline that holds is to frame every issue against the size of the transaction and the levers available to mitigate it. A revenue quality issue an escrow covers is not the same issue as one that dissolves the thesis.

Three questions when the two write-ups land.

Where do they disagree about next year's revenue, and on whose evidence? Which assumptions does the price rest on that neither stream verified? And which of those could still be settled before signing, by somebody already engaged?

Reconciling the streams does not prevent overpaying. It makes visible the part of the price that no evidence supports, which is a smaller claim and a more useful one. How the streams fit with everything else is M&A due diligence proper, and the scope question starts one level up, at due diligence itself.
