Buying a business in Switzerland: choose, verify, finance and manage the handover

Buying a business lets you start with a real operation: customers, a team, products and ways of working. It does not remove entrepreneurial risk. Your job is to understand what creates value, what could weaken it and what you will need to change after the handover.

This guide follows an SME acquisition from defining the project to the first hundred days. It is for buyers and for sellers preparing a serious information package. If you are considering different routes, compare it with starting a business and expanding an existing operation into Switzerland.

Edition dated 11 September 2026. Scenarios and amounts are fictional; they are neither market valuations nor financing offers. Legal structure, warranties and taxation must be examined for each transaction with qualified professionals. Some linked sources are in French.

1. Define your project before reading listings

Write down what you seek: sector, region, size, operational role, expected income and available skills. Add what you do not want to take on: night work, dependence on unfamiliar technology, heavy investment or a business closely tied to one individual. These boundaries prevent confusion between a good business and one suited to your project.

Calculate your total budget. It includes price, transaction expenses, cash needs, immediate investment and your personal safety margin. Purchasing capacity is not simply the amount you could hand to the seller on signing day.

Prepare a buyer profile: experience, motivation, availability, project, deployable equity and timetable. You need not publish all financial evidence, but you should be able to demonstrate seriousness once discussions become confidential. A seller also wants business continuity and a transaction that can actually happen.

Classify criteria as essential, preferred or negotiable. Use the same scorecard for every opportunity. You will compare businesses more objectively and explain why an apparently attractive listing ultimately fails to meet your needs.

2. Move from a listing to confidential information

A listing provides an initial view; it cannot validate a price or future profitability. Ask what is being sold, why the owner is selling, their current involvement and the principal operating figures. Identify information that is dated or presented as an estimate.

Before access to sensitive data, define confidentiality, authorised recipients and permitted document use. A confidentiality undertaking organises the exchange; it does not itself prove the figures are correct. Keep track of received versions and unanswered questions.

Avoid contacting employees, customers or suppliers directly without arrangements agreed with the seller. Discretion protects the business you hope to buy. Share information progressively: aggregated figures first, more detailed documents later, then targeted verification when the project is sufficiently advanced.

At the first meeting, ask the owner to describe a real working week: tasks, decisions, incidents, sales and key relationships. This often reveals dependencies absent from the income statement. Note what you will need to learn, delegate or replace after their departure.

3. Understand exactly what you are buying

In a share transaction, you acquire an ownership interest in the company, which retains its assets and commitments. In an asset transaction, the transferred scope must be defined precisely. Either structure can involve transfer obligations, liabilities and specific formalities.

List the elements concerned: customers, brand, stock, equipment, software, domain, contracts, receivables, debts, staff and authorisations. Identify what the seller actually owns, what is leased and what requires third-party agreement. Equipment financed through leasing is not necessarily freely transferable property.

A sole proprietorship does not have shares to buy like a Sàrl/GmbH. Its transfer concerns the business activity and assets under the chosen arrangement. SECO’s sole-proprietorship guidance outlines transfer principles; have the rules for your transaction determined.

Do not treat an asset purchase as an automatic guarantee against liabilities. Contracts, employment relationships, certain statutory responsibilities and transfer arrangements need examination. Compare structures before finalising price, because economic and tax outcomes can differ for each party.

4. Analyse profitability that can continue after the sale

Request several years of accounts, recent management figures and useful monthly data. Reconcile revenue with sales, returns and available receipts or filings. Understand changes, seasonality, credit notes, unpaid bills and exceptional events. A one-off increase does not automatically represent a lasting trend.

Adjust the owner’s remuneration to reflect replacement cost. Identify personal expenditure, related-party rents and non-recurring income. Document every adjustment. A seller’s list of “possible savings” is not yet profit available to the buyer.

Study margins by product, customer or activity where data allows. Revenue growth can conceal deteriorating margins. Check deferred maintenance too: results look better when equipment has not been replaced, but the cost may await you after acquisition.

Analyse customer concentration, renewable contracts and income personally dependent on the seller. Ask how customers arrive, why they stay and which relationships need transferring. A longstanding customer base is no promise of loyalty to a new owner.

5. Build a valuation, then negotiate a price

Value can be examined through earnings, future cash flows, assets or genuinely relevant comparable transactions. Methods produce a range for discussion, not an indisputable truth. Price also depends on scope, financing, risks, timing and payment arrangements.

Distinguish enterprise value from the price of shares. Cash, financial debt, shareholder current accounts and working capital can change the final amount. Define included items precisely so that both parties do not think they have accepted the same figure while using different assumptions.

Fictional example: from reported earnings to required funding

An SME reports CHF 160,000 in earnings before interest, taxes, depreciation and amortisation. After allowing for an inadequately recorded replacement salary and a recurring expense, normalised earnings used for analysis are CHF 120,000. This is not free cash: investment, taxes and working-capital movements remain to be addressed.

Assume a negotiated price of CHF 360,000, transaction costs of CHF 20,000, immediate investment of CHF 40,000 and liquidity needs of CHF 60,000. The project requires CHF 480,000 in funding. Financing only the price would leave CHF 120,000 of needs unanswered. These amounts illustrate the method and do not imply a recommended market multiple.

Prepare a reasoned offer with your assumptions, items to verify and conditions. When you find a risk, estimate its possible effect before requesting an arbitrary discount. Some issues call for a warranty, condition precedent or transition support rather than simply a lower price.

6. Organise due diligence proportionate to the stakes

Due diligence examines information and risks before a definitive commitment. Its scope depends on the business and transaction. The SECO SME portal explains this preliminary examination. Organise work with your accountant, legal adviser and, where necessary, a technical specialist.

Financial review covers accounts, cash, debt, revenue quality and off-balance-sheet commitments. Tax review examines filings, inspections, VAT and identified exposures. Legal review addresses ownership, contracts, disputes, warranties, authorisations and transfer restrictions. Assign every question an owner and a deadline.

Operational review covers equipment, suppliers, stock, quality, production capacity and dependencies. People review examines roles, remuneration, leave, overtime, pensions and key employees. Digital review checks licences, access, intellectual property, backups, cybersecurity and essential providers.

For each finding, record evidence examined, the answer received, estimated impact and proposed treatment. A full data room does not mean an audit is complete. Important questions must lead to a clear conclusion: acceptable, to be corrected, to be covered by a warranty or incompatible with acquisition.

Protect personal data during review: restricted access, progressive sharing, redaction where appropriate and deletion according to commitments. The FDPIC explains data-protection obligations. Commercial curiosity does not justify unlimited access to every individual file.

7. Finance the entire project without constraining operations

Combine funding appropriate to your circumstances: equity, bank lending, investors and possibly a seller loan. No universal equity percentage guarantees bank approval. Lenders assess the business, your experience, available cash flows, security and transaction terms.

A seller loan defers part of the payment and creates a repayment obligation. Define interest, instalments, security, ranking and consequences of default. An earn-out linked to results needs a precise formula, accounting rules, information rights and a dispute-resolution mechanism.

Test debt service under a prudent scenario after your remuneration, taxes, necessary investment and working capital. A profitable company can still struggle with overly rapid repayment. Keep an operating reserve separate from money intended to pay the seller.

Prepare a monthly cash trajectory, including lower sales, a customer departure and unexpected repair expenditure. Compare possible responses: spending reductions, deferred investment or an actually available emergency resource. Balanced financing supports the transition without turning every incident into a crisis.

8. Move from the letter of intent to the contract

A letter of intent can define scope, indicative price, confidentiality, negotiation exclusivity, due diligence and timetable. Some clauses may bind the parties even if the document is not a definitive sale. Have their effect clearly identified before signing.

The final agreement should describe the transfer, price, adjustments, payments, seller statements, warranties and remedies. Limits, duration, exclusions and notification procedures deserve as much attention as the headline amount. A warranty that is hard to enforce offers limited protection.

Distinguish signing the agreement from completing the transaction. Conditions may need fulfilment between them: financing, landlord consent, customer approval, authorisation or remediation. Give every condition an owner and evidence requirement, and specify consequences if it is not met.

Have each party’s taxes, VAT treatment and any applicable notification procedure for the transfer analysed. Do not automatically add a VAT rate to the overall price. Tax treatment depends on structure, assets, parties and legal conditions; validate it before fixing the economics of the agreement.

9. Secure employees, premises and essential relationships

For a business transfer, articles 333 and following of the Code of Obligations may apply to employment relationships, including information and, in some cases, consultation. A simple share transfer generally leaves the same employer in place. Have the timetable and obligations for the structure checked. The Code of Obligations is available on Fedlex.

List indispensable people and what they know. Prepare discussions with the seller: who announces what, when and how will questions be answered? Confidentiality must not lead to ignoring legal obligations or leaving the team to discover essential information by chance.

For premises, examine lease term, permitted use, works, future rent and transfer or change-of-control conditions. For customers and suppliers, identify clauses requiring consent. Check professional authorisations separately: their continuation cannot be inferred simply from keeping the same trading name.

Organise access transfers: banking, invoicing, domain, telephony, software, platforms and backups. Use named accounts and a secure procedure rather than emailing a password list. Test essential access before the person who managed it actually leaves.

10. Prepare completion and the first hundred days

On completion day, use a checklist: conditions fulfilled, funds available, signed documents, inventory, keys, bank signing powers, access and communications. Name a contact to address discrepancies immediately. The handover should be documented, not just celebrated.

• Days 1 to 30: listen and stabilise. Meet the team, understand operations, confirm priority customers and review cash weekly. Avoid changing every practice before understanding its purpose.
• Days 31 to 60: address weaknesses. Resolve urgent findings from due diligence, document essential processes and clarify responsibilities. Choose a few visible, achievable improvements.
• Days 61 to 100: prepare growth. Recalibrate the budget, offer, sales organisation and investments using actual observations. Decide what to accelerate, postpone or abandon.

Define the seller’s support: duration, availability, remuneration, tasks, relationship introductions and decision boundaries. An unclear continuing presence can undermine the new owner’s authority. Plan a gradual handover and an end date the team understands.

Track orders, margin, customer departures, incidents, receipts and cash. Compare results with the acquisition scenario without seeking someone to blame for every variance. Early months should produce a more reliable understanding of the business and a greater ability to act.

11. Signals that justify slowing down

Figures that cannot be reconciled, persistent refusal to provide essential documents, uncertain asset ownership or pressure to pay before verification require pausing the decision. A dominant customer without a transferable relationship or an unresolved authorisation can undermine the project.

Not every defect rules out an acquisition. The issue is to understand, quantify and address the risk. Set walk-away criteria before becoming too emotionally committed. Abandoning a negotiation in time can be a sound entrepreneurial decision.

Frequently asked questions

Must I know the sector perfectly?

You need to understand its success factors and have essential skills available. Transferable experience can help, but it does not replace a mandatory qualification or critical know-how. Plan who will fill gaps and at what cost.

How long does an acquisition take?

Timing depends on the information, due diligence, financing and approvals required. Build a timetable with stages and dependencies rather than an isolated signing date. Do not shorten important verification to meet a deadline that has become artificial.

Is stock always included in the price?

No. Define inclusion, inventory, valuation and treatment of unsaleable items. Clarify the reference date and movements up to handover. Apply the same reasoning to cash, receivables and debts.

Can I buy as a person living abroad?

Ownership, financing, representation and the right to work must be considered separately. Authorisations or sector rules may apply. SEM provides guidance on gainful activity; have your complete scenario examined.

What should a seller do next?

Prepare a coherent information package, clarify scope and document dependence on the owner. Organised answers speed up useful conversations. Preserve confidentiality and validate transfer arrangements before promising net proceeds or a definitive timetable.
