5 M&A Diligence Deliverables and Which One You Actually Need
Diligence is not one document. It is a set of distinct workstreams, and buying the wrong one, or all of them when you need two, is how deals get expensive without getting safer. Here are the five deliverables that come up most on lower-middle-market deals, and how to tell which you need.
The five deliverables at a glance
| Deliverable | What it answers | Typical fit |
|---|---|---|
| QoE data book | Are the earnings and working capital real? | Most deals under roughly $10M; lender-compatible |
| Full QoE report | Same, in formal written form | Larger, PE, complex cap table, or high-debt deals |
| Financial due diligence | Earnings plus the broader finance function | When a buyer wants controls and reporting reviewed too |
| Tax due diligence | What is the tax exposure and structure? | Most deals; often bolted on through a tax partner |
| Valuation | What are the earnings worth? | Situational; usually a chartered business valuator |
In practice, most lower-middle-market buyers need the earnings analysis (a data book or report) plus tax diligence. We default to the data book unless the size or complexity of the deal calls for the full report, because the diligence is identical and the report is just packaging.
- The Quality of Earnings data book
An Excel-based analysis, sometimes called a “QoE light,” that does the full diligence on earnings and working capital without packaging it as a long report. For most deals under roughly ten million dollars it is the right deliverable: same rigor, lender-compatible, lower cost. A fifty-page report is overkill for a three-million-dollar business.
- The full Quality of Earnings report
The same analysis delivered as a formal written report. It is built for larger deals, private-equity buyers, complex capital structures, or high-debt situations where the narrative and the audit trail matter to multiple parties. See the Quality of Earnings report entry for what it covers.
- Financial due diligence
Often used interchangeably with QoE, though some buyers mean a broader review of the financial function: controls, systems, forecasting, and reporting quality alongside earnings. Clarify the scope before you commission it so you are not paying twice for the same analysis under two names.
- Tax due diligence
A separate review of the target’s tax exposure and structure. A QoE does not cover it. On many deals it is bolted on through a tax partner so the buyer gets it without paying full freight for two standalone engagements.
- Valuation
An independent opinion of what the business is worth, typically from a chartered business valuator. A QoE tells you whether the earnings are real; a valuation tells you what those earnings are worth. They answer different questions and are usually done by different specialists.
How to choose
Most lower-middle-market buyers need the earnings and working-capital analysis (item 1 or 2) plus, depending on the deal, tax diligence. Valuation is situational. The deliverable should match the size and complexity of the deal, not the longest option on the menu.
Frequently asked questions
Is a QoE the same as financial due diligence?
Often, but not always. Some buyers use “financial due diligence” to mean a broader review. Agree on scope up front so the deliverable matches what you actually need.
Do I need a full report or a data book?
For most deals under about ten million dollars, the data book delivers the same diligence and is accepted by lenders. The full report is for larger or more complex deals.
Does a QoE include tax and valuation?
No. Those are separate workstreams. Tax diligence is frequently added through a partner; valuation is a distinct engagement, usually by a chartered business valuator.
