Industry research consistently identifies pre-process preparation as the highest-leverage phase of an exit advisory engagement. DueDilio's 2025 Quality of Earnings analysis documents a 0.5 to 1.5x multiple uplift in lower-middle-market transactions tied to sell-side QoE work. The uplift is produced in the preparation window, not in the marketing phase that follows.
The shorthand is "the 90-day pre-LOI window." In practice, the disciplined version of pre-process work runs anywhere from 60 to 180 days depending on business complexity, owner readiness, and the integration of preparation activities. Below the 60-day floor, the work is necessarily abbreviated and key analyses are compressed or skipped. Above the 180-day ceiling, the advisor is either accommodating an unprepared seller or carrying excess overhead. The 90-day range is the typical center of the distribution for businesses with $5M to $25M in EBITDA.
Week 1 to Week 2: Scoping
The first two weeks of the engagement establish the analytical scope. The advisor and seller review the financial statements, identify the candidate QoE firms, scope the QoE engagement, and align on the deliverables of the pre-process phase. The deliverables list typically includes the buyer-lens audit, the Quality of Earnings document, the normalization workbook, the customer concentration analysis, the working capital baseline model, and the prepared confidential information memorandum (CIM) framework.
This phase is short but consequential. An advisor who does not scope explicitly tends to deliver less than promised in the later phases, because the scope is implicit rather than agreed. Owners can require an explicit deliverables timeline in the engagement letter or in a written kick-off memo during week one.
Week 2 to Week 8: Analytical Work
The bulk of pre-process work runs across this six-week window. The Quality of Earnings firm is engaged and begins its work, which typically takes four to eight weeks for a lower-middle-market business with reasonably clean financials. In parallel, the advisor builds the buyer-lens audit, identifies the target buyer set, runs the customer concentration analysis, and prepares the working capital baseline.
The buyer-lens audit, covered separately on this site, models the business through the underwriting lenses of strategic acquirers, financial sponsors, family offices, and (where applicable) search funds. The audit's output is the target buyer-set narrowing recommendation: which archetypes are realistic, which are not, and where the realistic valuation ranges sit for each.
The normalization work runs alongside the QoE. Every owner-compensation addback is documented and supported. Every related-party transaction is disentangled. Every accounting policy choice that affects EBITDA is identified and justified. The output is a normalization workbook the buyer's diligence team can review without surprises.
The customer concentration analysis maps revenue dependency by customer for the trailing three years. For businesses with concentration above approximately 40 percent, the analysis includes a retention narrative, a churn-risk assessment, and (where possible) interventions to reduce concentration before going to market. The analysis matters because customer concentration is one of the structural inputs that most affects financial-sponsor underwriting, as covered in the buyer-archetype methodology primer.
Week 8 to Week 12: Synthesis and Risk-Vector Mapping
By week eight, the analytical artifacts are complete or nearly complete. The next phase is synthesis: pulling the QoE, the buyer-lens audit, the normalization, and the customer concentration analysis into a coherent narrative about the business, its risks, and its valuation range.
The synthesis produces a risk-vector map. Every issue a buyer's diligence team is likely to discover, the advisor and seller have already discovered. For each issue, there is a documented position: either an explanation, a quantification, or an intervention. The risk-vector map is what allows the seller to enter the LOI period with a clear view of where post-LOI compression is likely to come from, which is the difference between forecastable compression and surprise compression.
The Cordis Institute Working Paper WP-001 (The Preparation Gap in Early 2026, SSRN Abstract 6515478) frames this synthesis as the central output of competent pre-process advisory: the difference between what an advisor does in the 60 days before going to market and what a buyer's diligence team will find in the 60 days after LOI, with the seller's outcome determined by how small that difference is.
Week 12 to Week 14: CIM Preparation and Buyer-Set Finalization
The final two weeks of the pre-process phase produce the confidential information memorandum (CIM), the teaser, and the finalized buyer-set list. The CIM is built from the analytical artifacts: it presents the business through the buyer-lens framing developed in the buyer-lens audit. The teaser is the abbreviated version that goes to the broader buyer list.
The buyer-set list is the operational output of the buyer-lens audit. It is structured by archetype: which strategic acquirers will be approached first, in what sequence; which financial sponsors will receive the teaser; which family offices may have interest. Search funds may be excluded entirely if the business is above their typical revenue range. The list is sequenced rather than blanket: top-priority buyers receive direct outreach with personalized framing, second-tier buyers receive the standard teaser, and the broad outreach happens in subsequent waves if needed.
The Variance: When 90 Days Is Not Enough
Some businesses require more than 90 days of pre-process work. Businesses with high customer concentration may need a 6 to 12-month diversification intervention before going to market. Businesses with messy financials, complicated capital structures, or unresolved related-party transactions may need to clean up before pre-process work even begins. Businesses with key-person dependency may need a 6-month management transition before they can be presented as continuity opportunities to family-office buyers.
An advisor who tells the owner "we need 6 months in pre-process before we are ready to go to market" is not delaying the engagement. They are identifying the work that produces a competent transaction. The 60-to-180-day range in the literature is a typical range, not a hard cap.
The Failure Mode: 30-Day Pre-Process
The failure mode is compression of the pre-process window to 30 days or less. In a 30-day window, QoE cannot be completed (the typical QoE timeline is four to eight weeks). The buyer-lens audit gets reduced to a buyer list rather than an underwriting analysis. Normalization and customer concentration work get shortened. Risk-vector mapping is essentially skipped.
The marketing package that goes out at the end of a 30-day pre-process window contains everything a confidential information memorandum is supposed to contain, but the analytical depth behind it is materially thinner. Buyers discover the gaps in their diligence. The seller experiences the gaps as post-LOI compression. The advisor's involvement in the discovery is limited, because the gaps were not surfaced in pre-process.
"Compressed pre-process windows produce compressed close values. The math is structural: the work that is not done before the buyer is approached gets discovered by the buyer's diligence team, which is the same as discovering it via a price renegotiation. Advisors who shortcut the window are not saving time, they are transferring the cost of the work to the seller, denominated in headline value." Ron Smith, Managing Partner, Cordis Group LLC.

How Owners Can Evaluate the Window in Practice
Three signals during the first month of an engagement tell an owner whether the pre-process window is being used well.
First, are the analytical artifacts being produced on the timeline scoped in the engagement letter? Buyer-lens audit, QoE engagement, normalization workbook, customer concentration analysis, working capital baseline: each should have a documented status by week four.
Second, are the artifacts being integrated, or are they parallel work streams that do not inform each other? A QoE that does not reflect the buyer-lens audit's archetype findings is a binder, not a discipline. A buyer-lens audit that does not reflect the normalization work's adjusted EBITDA is a marketing list, not an analytical exercise.
Third, is the advisor identifying risks proactively, or only when asked? The disciplined advisor surfaces customer concentration issues, working capital fragility, related-party complications, and accounting policy choices proactively, with an intervention plan or a documented position. The undisciplined advisor waits for the buyer's diligence team to identify them.
