Product guide
One deal. One investigation record. A clearer next decision.
Deal Preflight is evidence-driven buyer-side due-diligence software for buyers of small online businesses. It reconstructs the listing economics, separates seller claims from proof, organizes the investigation, and keeps the decision current as facts change.
The complete workflow
The report is the start of the investigation, not the end.
Decide whether the listing deserves more time.
Import a public marketplace listing, paste the seller's copy, or enter the deal manually. Confirm the extracted facts before Deal Preflight calculates anything.
Free output: economics, downside cases, major risk flags, Deal Score, and Claim Verification.
Turn every concern into a concrete request.
The complete report connects each material issue to the seller question, document request, good answer, warning answer, and decision gate it affects.
Paid output: a deal-specific investigation plan you can use in the next seller call.
Work the evidence instead of losing it in messages.
Upload a CSV, TSV, or Excel workbook, choose the date and value columns, compare the observed result with the saved claim, and log seller replies against the relevant finding.
Workspace output: an evidence ledger that keeps claims, calculations, documents, and buyer decisions distinct.
Regenerate the decision when the facts change.
Update deal facts, resolve or escalate findings, and create a new report version. The earlier report remains preserved so you can see exactly what changed and why.
Included for the same deal: updated report versions without using another report credit.
Inside a complete report
Built to produce actions, not a generic summary.
Transparent deal math
Price and revenue multiples, normalized profit, payback thresholds, cost bridges, and 10%, 25%, and 50% downside cases.
Proof kept separate
Deal Score rates the supplied deal. Claim Verification measures support for the seller's important claims.
Questions you can send
Prioritized seller questions with why each matters, what a good answer looks like, warning signs, and exact evidence requests.
An investigation record
Seller replies, reconciliations, finding status, evidence assessments, public checks, and every generated report version stay tied to the deal.

Where specialists enter the investigation
Deal Preflight organizes the claims, calculations, evidence requests, and unresolved decision gates. It does not independently authenticate private seller records or replace legal, accounting, tax, financial, or technical advice. Bring qualified specialists into the deal where those checks require professional judgment.
