Selling a mid-sized, privately held business typically takes 7 to 10 months from the time you engage an advisor to the closing date. That range covers preparation, marketing to buyers, negotiation, and due diligence. Well-prepared companies with clean financials tend to sell faster; complex ownership structures, cross-border buyers, or incomplete records tend to add months. This guide walks through each phase so you can set realistic expectations and plan around the sale rather than around a single closing date.
The short answer
Most sell-side engagements for companies in the €50M–€500M revenue range typically run 7 to 10 months end to end. Larger, more complex transactions, or those involving a cross-border buyer, regularly extend past that window because of added regulatory review, financing timelines, or more extensive due diligence. The single biggest variable within your control is preparation: how ready your financials, contracts, and management structure are before you go to market.
There is no fixed number of months that applies to every company. A business with audited financials, a documented management team, and no owner-dependency issues can move through the early phases quickly. A business with commingled personal and corporate expenses, unresolved legal matters, or a single owner who is the business will need more preparation time before it can go to market credibly.
Phase-by-phase timeline
The table below reflects a typical sequence for a lower-middle-market sale. Actual durations vary by deal size, sector, and buyer type (strategic, private equity, or family office).
| Phase | What happens | Typical duration |
|---|---|---|
| Preparation | Financial normalization, materials drafting, internal alignment | 4–8 weeks |
| Marketing and outreach | Buyer list development, teaser distribution, confidentiality agreements | 4–8 weeks |
| Buyer screening and management meetings | Indications of interest, follow-up calls, site visits | 6–10 weeks |
| Letter of intent and negotiation | Selecting a buyer, negotiating key terms | 2–4 weeks |
| Due diligence | Financial, legal, operational, and commercial review | 8–14 weeks |
| Definitive agreement and closing | Final contract negotiation, closing conditions, funding | 4–8 weeks |
Add these ranges and the low end lands around six months; the high end stretches past a year. Most transactions in this size range land in the middle, at roughly 7 to 10 months. Due diligence after a signed letter of intent typically accounts for roughly three to four months of that total on its own, which is why sellers who treat the LOI as "the finish line" are often surprised by how much work remains.
What speeds up a sale
Several factors reliably shorten the timeline:
- Clean, reviewed or audited financials. Buyers and their lenders move faster when they trust the numbers on day one.
- Normalized earnings already documented. If add-backs and one-time items are explained in writing before buyers ask, you remove a common source of back-and-forth.
- A management team that is not entirely dependent on the owner. This reduces buyer concern about post-sale continuity and shortens the negotiation over transition terms.
- Organized legal and contract files. Missing or unsigned customer contracts, leases, or IP assignments are a frequent cause of due diligence delay.
- A realistic price expectation from the outset. Sellers who anchor to a defensible range close faster than those who require repeated re-education on valuation.
- A single decision-maker, or an aligned ownership group. Multiple family shareholders who have not agreed on terms in advance routinely add weeks to negotiation.
What slows a sale down
The same list, in reverse, explains most delays:
- Financial records that require reconstruction or reconciliation before they can be shared.
- Customer concentration or contract issues discovered mid-process rather than disclosed upfront.
- Owner-dependent operations that require buyers to negotiate longer transition or consulting periods.
- Regulatory or antitrust review, more common in certain sectors and in larger deals.
- Cross-border elements: currency, tax structuring, and foreign buyer financing typically add time relative to a domestic-only transaction.
- Renegotiation after diligence findings, sometimes called a "second negotiation," which can add four to eight weeks if working capital or earnings quality issues surface late.
Why your timeline may differ
Deal size, sector, and buyer type all move the number. A strategic buyer already familiar with your industry may move through screening faster than a financial sponsor building a new investment thesis. A cross-border buyer may need additional weeks for currency hedging, tax structuring, or home-country approvals. Sectors with more regulatory touchpoints, or with meaningful customer concentration, tend to see longer due diligence phases than others — dynamics that differ across the sectors we serve, from real estate and hospitality to consumer, retail and digital.
Preparation is the one variable you control most directly, long before a buyer ever sees your business. This is the reasoning behind pre-transaction readiness work: resolving the issues that would otherwise surface during due diligence, before you are under a buyer's clock. The Goldsmith™ process is built around exactly this — reviewing financial quality, governance, and operational independence before you go to market, so the process that follows moves as efficiently as your situation allows.
Example scenario: a founder-owned manufacturing company with $40M in revenue spends two months compiling three years of normalized financials and documenting management responsibilities before going to market. Because buyers receive clean materials from the outset, the process from first buyer conversation to signed letter of intent takes about ten weeks, and due diligence closes in twelve weeks with no material surprises. A comparable company that skips preparation and discloses unresolved contract issues during diligence often adds two to three months to the same stage.
Frequently asked questions
What is the fastest a mid-sized business sale can realistically close?
Very well-prepared companies with a single motivated buyer and straightforward financials have closed in as little as four to five months, but this is the exception rather than the norm. Most transactions in the €50M–€500M range typically take 7 to 10 months, and rushing past preparation or due diligence usually creates risk rather than saving real time.
Does a higher asking price make a sale take longer?
Not directly, but an unrealistic price expectation does. If your price is not supported by comparable transaction data or your own financial performance, expect more buyer pushback, more re-negotiation, and a longer path to a signed letter of intent.
How much of the timeline is due diligence?
Due diligence after a signed letter of intent typically takes three to four months for lower-middle-market transactions, covering financial, legal, operational, and commercial review. This is often the longest single phase and the one most affected by how organized your records are going in.
Can cross-border buyers extend the timeline significantly?
Yes. Cross-border transactions often add weeks or months for currency and tax structuring, home-country regulatory approval, and additional legal review across two jurisdictions.
