How to Prepare Your Business for Sale

Business sale preparation checklist: the financial, operational, and legal steps buyers scrutinize — and how to complete them before going to market.

Business owners who prepare 12–24 months before going to market consistently achieve better outcomes than those who begin only after a buyer approaches. Preparation is not administrative work — it is value creation.

According to PwC’s 2025 Global M&A Trends report, sellers with clean financials, documented operations, and professional deal materials achieve 15–25% higher multiples than unassisted owners going to market unprepared. The difference compounds at every stage of due diligence: a well-prepared business moves faster, attracts better buyers, and gives buyers fewer reasons to discount the price.

Amafi is a confidential AI M&A matching marketplace — when you register, the AI deal toolkit generates your financial model, teaser, and CIM as you build your profile, so preparation and materials happen simultaneously. Start confidentially →


Why Preparation Determines Price

Buyers conduct due diligence to reduce uncertainty. Every gap they find — missing records, undocumented processes, concentrated customer risk — is converted into a price reduction, an earnout, or a request for warranty and indemnity coverage that shifts risk back to you.

Preparation closes those gaps before the buyer finds them. A seller who can answer every diligence question before it is asked moves faster, commands better terms, and retains more of the negotiating leverage.

“The sellers who get the best outcomes are the ones who’ve been running their business as if it were always for sale — clean books, documented processes, no surprises. By the time a buyer asks a hard question, they already have the answer ready.” — Daniel Bae, Founder & CEO, Amafi (has advised on $30B+ in transactions)


Financial Preparation

Financial preparation is the most time-sensitive element. Buyers expect three full years of accounts, and restating or cleaning up prior years after a sale process begins is difficult.

Three Years of Clean Accounts

Prepare three years of profit and loss statements, balance sheets, and cash flow statements. These should be audited or independently reviewed where possible — reviewed accounts from a reputable firm are acceptable for mid-market deals; audited accounts are standard above $10 million EBITDA.

If your accounts have been prepared purely for tax minimization (common in owner-managed businesses), a restatement showing commercial profitability is essential before going to market.

EBITDA Normalization

Every add-back to EBITDA must be documented with supporting evidence. Common legitimate add-backs:

  • Owner compensation above market: if you pay yourself $400K but a replacement CEO would cost $200K, the $200K excess is an add-back
  • Personal expenses: personal vehicles, travel, memberships run through the business
  • One-off items: restructuring costs, legal disputes, COVID-related government support
  • Non-cash items: depreciation on assets not relevant to the business

Buyers will test every add-back. Prepare a schedule with line-item justification and supporting documents (payroll records, invoices, tax filings). See EBITDA add-backs explained for a full breakdown.

Working Capital

Buyers will require a normalized working capital analysis — the level of working capital needed to run the business on a going-concern basis. If working capital at close differs materially from the agreed norm, price adjustments follow. Prepare a 12-month working capital bridge showing seasonal patterns and any structural changes.

Monthly Management Accounts

Maintain current monthly management accounts through the sale process. Buyers will want to see the most recent 12 months of monthly P&L at the letter of intent stage and full current-year actuals by due diligence.


Operational Preparation

Buyers pay more for businesses that can operate without the founder. Operational preparation means reducing the dependency of the business on any single person — including you.

Key Person Dependency

The most common reason mid-market businesses trade at lower multiples is that the business is the founder. Buyers discount for key person risk because they cannot be certain the business survives a management transition.

Mitigation steps:

  • Hire or promote a second-in-command who can manage day-to-day operations
  • Document all processes, client relationships, and supplier agreements
  • Transfer client relationships to multiple people in the organization
  • Start stepping back from daily operational decisions 12+ months before sale

Customer Concentration

A single customer representing more than 20–25% of revenue is a material risk in any sale process. Buyers will either discount the price or request earnout provisions tied to customer retention.

Mitigation: actively diversify revenue before going to market. Losing a concentrated customer before or shortly after sale is one of the most common deal-breaking scenarios.

Recurring Revenue and Contracts

Documented, contracted recurring revenue is valued significantly higher than equivalent discretionary revenue. If you have informal customer arrangements that function as recurring contracts, formalize them. Subscription, retainer, and multi-year service agreements all improve the quality of earnings story.


Legal preparation surfaces issues that could delay or derail a deal at closing.

IP and Asset Ownership

Confirm that all intellectual property — software, trademarks, patents, brands, client databases — is registered in the business entity, not in a personal name or a related company. Buyers acquiring a business expect to own what they are paying for.

Contracts and Transferability

Review all material contracts for change-of-control provisions. Many supplier, customer, and financing agreements include clauses that require consent or terminate on a change of ownership. Identifying these early allows time to obtain consents or negotiate replacement terms.

Licences and Regulatory Approvals

If the business operates under licences or regulatory approvals (financial services, healthcare, food, construction), confirm these are transferable and will not lapse on a change of control. Regulatory approval timelines vary by jurisdiction — in some APAC markets, healthcare or financial licences require 3–6 months of regulator engagement.

Ownership Structure

Confirm the cap table is clean: no disputed shareholdings, no informal agreements with employees or advisors, no convertible instruments that could dilute or complicate a sale. If there are minority shareholders, understand their rights (pre-emption, drag-along, tag-along) and whether their consent is required.


Vendor Due Diligence

A vendor due diligence (VDD) report — where you commission an independent review of your own business before going to market — is increasingly standard in mid-market transactions. A VDD report:

  • Identifies issues before buyers find them
  • Speeds up the buyer’s due diligence timeline
  • Demonstrates transparency and reduces buyer scepticism
  • Can be shared with all bidders, reducing redundant diligence requests

Deloitte’s M&A Advisory survey (2024) found that businesses with VDD reports completed due diligence 35% faster and with fewer price adjustments than those relying on buyer-driven diligence alone.

How Amafi Supports Preparation

When you register on Amafi, the platform’s AI deal toolkit generates your financial model, teaser, and CIM directly from your inputs. This is not a replacement for financial preparation — you still need clean accounts and a normalized EBITDA schedule. But it means the materials are ready when they are needed, not assembled in a rush after a buyer expresses interest.

The AI matching also means that while you are preparing, the platform can identify which types of buyers are most likely to be interested in your business — allowing you to prioritize preparation efforts that matter to the specific buyer universe most likely to engage.
