Most lower middle market business owners who achieve excellent exit outcomes share a common characteristic: they did not make the decision to sell in a hurry. They started preparing twelve to eighteen months, sometimes more, before they went to market. That preparation time is not about manufacturing financial results. It's about giving the business time to present its genuine best version, and giving the owner time to understand and optimize the process before the most consequential financial transaction of their professional life.
What follows is a practical, quarter-by-quarter guide to what the twelve months before engaging an M&A advisor should look like. For context on what comes after this preparation period, our guide to the seven phases of a successful business sale maps every stage.
Months 1–3: Establish Your Baseline
Get an honest, independent assessment of where you stand. A confidential conversation with an M&A advisor who has closed comparable transactions, without commitment to a future engagement, gives you a more accurate sense of your realistic range than any calculator. Our post on the five key drivers of business valuation covers revenue quality, management depth, EBITDA margin, customer concentration, and growth trajectory.
Pull three years of financials and understand them deeply. Compare them to your tax returns, understand every material difference, and identify the add-backs a normalization analysis would produce. Our guide on what EBITDA is explains the full normalization process. This work doesn't require an accounting firm yet, just the owner's direct attention.
Identify your three biggest saleability risks. Customer concentration, owner dependence, inconsistent financial records, key-person dependencies, pending legal matters, and below-market leases are the most common. Our post on the five most common business sale deal-killers covers each risk category and the steps that address it.
Months 4–6: Address Financial Presentation
Clean up the chart of accounts and expense categorization. If personal expenses have been running through the business, this is the period to separate and document them clearly, not necessarily eliminate them.
Commission or prepare a preliminary normalization schedule. A working draft you refine with your CPA is a reasonable starting point. Our dedicated guide on EBITDA add-backs and how they maximize your valuation covers every category and the documentation standard required.
Address any accounting methodology inconsistencies. If converting from cash to accrual basis, begin with enough lead time that it represents a consistent multi-year presentation, not a change made in the year of sale. Our guide on how to prepare your financials for a business sale covers all five dimensions of financial readiness.
Months 7–9: Strengthen the Business
Address customer concentration if it's a known issue. If your largest customer represents more than 25% of revenue, spend these months on active diversification or strengthening the contractual foundation of the relationship.
Build and document management depth. Identify where your absence would create the most immediate problems and begin developing team members or adding hires to fill those gaps.
The single highest-return preparation investment for most lower middle market businesses is reducing owner dependence. A business that can run without you is worth materially more, typically one to two turns of EBITDA multiple.
Conduct a pre-sale legal review. Engage outside counsel to systematically review litigation, tax compliance history, employment practices, IP ownership, and key agreements. Issues surfaced here can be addressed proactively; issues discovered in diligence cannot.
Months 10–12: Prepare for the Process
Commission a sell-side quality of earnings analysis. By this point, records are organized and the normalization schedule is developed. Our guide on the quality of earnings report explains what a sell-side QoE covers and why commissioning it proactively is one of the highest-return pre-sale investments available.
Develop your growth narrative. Identify the specific investments a buyer could make to accelerate growth and the extensions that would deepen existing customer relationships. This narrative becomes central to the CIM and management presentations.
Select your advisor. Evaluate candidates on sector expertise, transaction experience in your size range, buyer relationship depth, and the specific team who will work on your engagement. If you receive an unsolicited approach before you've engaged an advisor, our post on how to handle an unsolicited offer covers why that timing is precisely when you're most exposed.
One month before engaging your advisor, have in hand: three to five years of clean, reconciled financial statements; a preliminary normalization schedule with documentation; a completed or in-progress sell-side QoE; a list of pending legal matters and status; a management org chart with role descriptions; and a clear statement of your goals on price, structure, timeline, and post-close involvement.
The best exits are built twelve months before you go to market, not twelve days after you decide to sell.
