How to Prepare Commercial Due Diligence Materials

Prepare commercial due diligence materials as a chain from the business claim to the underlying customer, contract and operating evidence. Define the period and metric, reconcile inconsistencies, and give reviewers an index that explains what each file proves. A large folder is not the same as a usable commercial evidence pack.

Define the commercial questions

Start with the questions investors actually asked: who buys, why they buy, how sales convert, what customers pay, what remains after delivery costs and whether demand persists. Choose a period and responsible owner for each question. Do not begin by exporting every customer record.

Create a metric dictionary. A customer can mean a company, location, account or paying contract. Use the same definition in the deck and evidence pack. Keep pilots, signed contracts, invoices, recognized revenue and cash collections distinct.

Reconcile before compressing

Stripe explains that bookings and ARR are different measures. Use finance-reviewed definitions appropriate to your business rather than relabeling one as another. Contract length and collection timing can also differ from the period in which revenue is recognized.

Reconcile totals to an approved source, then show exclusions and adjustments. A CRM export might include closed-lost opportunities or duplicate parent and subsidiary records. A signed pilot may never have become paying usage. Investigate the discrepancy instead of selecting the larger number.

Build the evidence index

For each claim, include a short answer, metric definition, period, source location, reviewer, known limitation and permitted audience. Where practical, prepare an approved aggregate before asking anyone to access raw records.

Material contracts, customer communications and personal data may have restrictions. FTC guidance on data minimization and access supports limiting what is exposed. Ask qualified owners what can be shared; this worksheet does not determine disclosure obligations.

Worked example: reconcile the headline

Illustrative case: HarborOps's sales sheet lists twelve “customers.” A review finds eight paying locations, three unpaid pilots and one duplicate location. The commercial pack uses eight paying locations and reports pilots separately.

Commercial evidence index

Claim	Evidence	Limit and owner
Eight paying locations at period end	Reconciled account list and billing support	Location is the unit; finance review
Three unpaid pilots	Pilot agreements and current status	Not revenue; commercial owner
Sales cycle	Dated first-qualified and signed events	Small observed sample; sales owner
Renewal evidence	Contracts eligible for renewal in period	Immature cohorts identified explicitly

The revised pack is less dramatic and more useful. It explains the bridge from the earlier number rather than quietly changing the deck and hoping nobody notices.

Copy the pack checklist

Commercial question:
Headline answer:
Metric and customer-unit definition:
Observation period and cutoff:
Approved source and exact section:
Reconciliation to underlying records:
Exclusions / duplicates / adjustments:
Historical result / forecast / assumption:
Known evidence gap:
Preparation owner and finance reviewer:
Sharing approval and redaction needed:
Version and review date:

Complete one row, then ask someone unfamiliar with the analysis to reproduce its result. If they cannot determine the unit or denominator, improve the explanation before sharing.

Completion and common failures

Stop if the contract list and financial figures do not reconcile. Do not replace missing retention evidence with website traffic or a pipeline chart. If a request asks for more detail than you are authorized to share, route it for review and offer an approved alternative where appropriate.

You are finished when material claims have sources, definitions reconcile and unresolved gaps are visible. The existing data-room checklist owns the broad folder inventory. This lesson supplies a commercial evidence chain, not an audit opinion or accounting determination.
