Selling your limited company (AG) in Switzerland: The 7 preparation stages

Why anticipate 3 to 5 years before the sale?

The sale of a limited company cannot be improvised. Unlike a sole proprietorship, an AG involves a complex legal and administrative structure that requires time to be optimised.

Advance preparation of 3 to 5 years allows you to:

• Progressively clean up your finances without rushing
• Regularise all legal and shareholder aspects
• Optimise the tax structure of the sale
• Reduce your operational dependence
• Document all processes

Rushing mechanically reduces the value of your business. Buyers quickly detect a forced sale and adjust their offer downwards.

It is normal to take time. A successful Swiss SME transfer is above all a prepared transfer. Discover the common mistakes to avoid during a sale.

Stage 1: Evaluate the real value of your AG

Knowing the value of your limited company is the essential starting point. Without a realistic estimate, you risk either discouraging buyers with a price that is too high, or selling off your assets.

For an AG, three valuation methods are commonly used:

• Practitioners' method: combines substantive value and earnings value
• DCF (Discounted Cash Flow): discounts future cash flows
• EBITDA multiples: applies a sector coefficient to operating profit

A professional valuation avoids disappointments and structures the negotiation on objective bases.

Stage 2: Clean up and optimise your accounts

Buyers systematically analyse 3 to 5 years of financial history. Confused accounts or those mixed with private expenses immediately reduce the credibility of your file.

Priority actions to clean up your finances:

• Strictly separate professional and private expenses
• Regularise shareholder current accounts (undocumented loans, advances)
• Optimise the balance sheet structure (equity/debt ratio)
• Eliminate non-productive or personal assets
• Normalise exceptional charges

A specialised fiduciary can prepare auditable accounts that inspire confidence. This sale preparation facilitates due diligence and accelerates the transaction.

Clean accounts signal rigorous management and increase the perceived value of your AG.

Stage 3: Regularise the legal and shareholder structure

The legal structure of an AG must be impeccable. Any legal ambiguity worries buyers and can block the transaction or justify a significant discount.

Essential verification points:

• Up-to-date articles of association: compliant with the reality of the company and the latest legal amendments
• Minutes of general meetings: archived and complete (appointments, strategic decisions)
• Share distribution: clear and documented, without disputes between shareholders
• Commercial register: up-to-date entries (bodies, capital, address)
• Legal compliance: tax, social and regulatory obligations respected

A lawyer specialising in corporate law can audit your structure and identify points to regularise before putting it up for sale.

This stage reassures buyers and avoids unpleasant surprises during legal due diligence.

Stage 4: Prepare essential documentation

Complete and structured documentation accelerates the sales process and strengthens your credibility. Serious buyers expect a professional file.

Essential documents for due diligence:

• Audited annual accounts (last 3-5 financial years)
• Updated articles of association and minutes of general meetings
• Key contracts: main customers, strategic suppliers, commercial leases
• Detailed organisation chart and job descriptions
• List of assets (fixed assets, stocks, intellectual property)
• Tax and social history (compliance certificates)

Leez structures this information confidentially on the platform. You control precisely who accesses which documents, and when.

Well-prepared documentation reduces negotiation times and limits requests for price reductions linked to late "discoveries".

Stage 5: Reduce dependence on the owner

A company too dependent on its owner is structurally worth less. If you are the sole holder of customer relationships, technical know-how or strategic decisions, the buyer takes a major risk.

Strategies to reduce this dependence:

• Delegate progressively: transfer responsibilities to your team
• Formalise processes: document key procedures (production, sales, management)
• Strengthen management: identify and train an operational successor
• Diversify relationships: involve other people in customer and supplier contacts
• Automate: digitalise repetitive tasks

Objective: demonstrate that the company can function without you. This empowerment reassures the buyer and justifies a higher price.

Start this process 2-3 years before the sale so that the changes are integrated and visible in the results.

Stage 6: Anticipate the tax aspects of the sale

The taxation of a business sale in the form of an AG is complex. Theoretically, the sale of shares is exempt from tax in Switzerland, but several traps can transform this exemption into heavy taxation.

Major tax risks to anticipate:

• Indirect partial liquidation: disguised distribution of reserves taxed as income
• Withholding tax: withholding at source on certain distributions
• Private vs commercial wealth: qualification of shares that changes the tax regime
• Timing of the sale: coordination with other tax events

Advance tax planning with an expert can save you up to 50% of the net gain. Consult our detailed article on tax pitfalls to avoid.

Do not make any structural decision without specialised tax advice.

Stage 7: Define your confidentiality strategy

The transaction discretion is crucial. A premature public announcement can worry your employees, destabilise your customers and alert your competitors.

Levels of confidentiality to put in place:

• Anonymous announcement: sector, region and key figures without identifying the company
• Systematic NDA: before any disclosure of sensitive information
• Progressive disclosure: identity revealed only to qualified and committed buyers
• Internal communication: planned at the right time to avoid leaks

Leez integrates these protection mechanisms: buyer identity verification, NDAs integrated into the platform, precise control of the visibility of each piece of information.

You decide who sees what, and when. Discover the companies for sale on our platform to see how confidentiality is managed.
