What is an M&A due-diligence proposal?

An M&A due-diligence proposal outlines your plan to evaluate a target company’s financial, legal, operational, and strategic risks ahead of a potential acquisition or investment. It typically includes scope, timelines, data request processes, reporting methods, and issue escalation.

This type of proposal is commonly used:

  • When a company, fund, or buyer is considering acquiring another business
  • Ahead of LOI finalization, during exclusivity, or pre-closing
  • For carve-outs, full acquisitions, strategic investments, or acqui-hires
  • To surface deal risks before negotiations are finalized

It helps clients identify red flags, confirm assumptions, and reduce post-close surprises.

A strong proposal helps you:

  • Define the specific workstreams you’ll cover (e.g., financials, HR, legal, IP, tax)
  • Map deliverables to deal stage and decision-making needs
  • Set expectations for access, turnaround time, and communication cadence
  • Present findings clearly, with decision-oriented recommendations

When to use this proposal

Use this M&A due-diligence proposal when:

  • A client is considering acquiring or investing in another business
  • You’re supporting an internal corp dev team, external buyer, or investor
  • The transaction is moving into exclusivity or needs confirmatory diligence
  • A deal has material financial, legal, or regulatory complexity
  • The acquirer lacks bandwidth or in-house expertise to run full diligence

It’s especially useful when a fast-moving deal needs structured, credible diligence within a short time frame.

What to include in an M&A due-diligence proposal

Use this template to walk the client through your process — from kickoff to findings — in structured, decision-ready language.

  • Project overview: Summarize the context of the deal and the role your diligence will play in supporting the client’s decision.
  • Scope of review: Define what’s in scope — financials, contracts, litigation, IP, HR, tech, compliance, tax — and what’s out.
  • Document request and data access: Explain how you’ll request, track, and organize access to the target company’s information.
  • Key workstreams: Break down responsibilities — who’s leading financial modeling, legal review, compliance checks, etc.
  • Risk flagging and escalation: Show how material issues will be flagged in real time, not buried in end-stage memos.
  • Deliverables: List outputs — risk matrices, issue summaries, financial analyses, red flag memos, integration notes (if scoped).
  • Timeline and phases: Break into phases — kickoff, early findings, deep dive, final report — with expected durations for each.
  • Communication plan: Set cadence for check-ins, reporting format, and final debriefs. Clarify access expectations with target company.
  • Pricing: Offer clear pricing — fixed fee, hourly cap, or per-workstream. Include optional add-ons like post-close integration support.
  • Next steps: End with a clear CTA — such as signing an NDA, confirming access to the data room, or scheduling the kickoff.

How to write an effective M&A due-diligence proposal

This proposal should feel structured, fast-moving, and risk-aware — especially for buyers navigating deal timelines or investor pressure.

  • Be clear about what’s in and out of scope: Ambiguity leads to gaps. Buyers hate surprises.
  • Tailor by deal stage: Use lighter review structures pre-LOI and more detailed scopes post-exclusivity.
  • Flag real-world outcomes: Emphasize that you’ll identify deal-breakers, pricing adjustments, or post-close liabilities.
  • Show speed and structure: Acquirers want fast answers — offer lightweight early reads before full reports.
  • Avoid bloat: Clients don’t want a 100-page memo — they want confidence and actionable risk calls.

Frequently asked questions (FAQs)

How many workstreams should I include in the proposal?

Anchor to what you can execute well. For financial buyers, include financials, tax, HR, and legal. For strategic acquirers, layer in ops and tech if relevant.

Should I include early-read deliverables or just a final report?

Always include interim findings. Buyers want issues surfaced fast — not bundled into a final memo after time’s run out.

What if access to the data room is delayed?

Build in contingencies. Offer a flexible timeline or backload deep dives while starting with public data or seller interviews.

Should I price by hour, by phase, or fixed fee?

Use fixed or capped pricing when the scope is clear. For fluid deals or open-ended support, offer a base package with hourly overages.

Is it worth offering post-close support?

Yes — many clients overlook integration planning during diligence. Offering light-touch post-close advisory is a strong differentiator.
