Practical guide
These points support an initial assessment. The decisive legal, tax, financial and operational questions depend on the business, the people involved and the chosen transaction structure.
Define the business package that will be transferred
List the tangible and intangible elements needed to continue the activity: equipment, inventory, domain, brand, customer relationships, contracts, phone numbers, records, know-how and goodwill. State what remains with the owner, including cash, receivables, private assets or liabilities. Verify legal ownership and any financing or retention-of-title rights. A phrase such as sale of the business is not sufficiently precise because the sole proprietorship itself is not a separate shareholding vehicle. The agreement and price must refer to a documented transfer perimeter.
- inventory included and excluded assets and obligations
- verify ownership, encumbrances and transferability
- connect every price component to the defined perimeter
Review contracts, permits and the business name
Customer, supplier, lease, licence and service agreements may require assignment, consent or replacement. Permits can be personal, site-specific or dependent on qualifications and may not transfer automatically. The registered business name of a sole proprietorship includes the owner's surname, so the buyer must check future naming and commercial-register requirements. Build a matrix showing each relationship, value, term, counterparty and required action. A buyer cannot operate the business merely because equipment and a customer list were delivered if essential contracts or approvals remain unavailable.
- check assignment, termination and consent provisions
- confirm permit and professional qualification requirements
- plan the new name and commercial-register steps
Address employees and personal data correctly
Where a business or part of one transfers, Articles 333 and 333a of the Swiss Code of Obligations may affect employment relationships and information or consultation duties. Obtain advice before agreeing who transfers, on which date and with what accrued obligations. Employee and customer records also contain personal data; provide anonymised summaries during early review and disclose identifiable information only when necessary and secure. The transition plan should cover payroll, benefits, access, workplace, reporting lines and communications so people understand who their employer is after closing.
- assess statutory employment-transfer requirements
- minimise identifiable data during early due diligence
- coordinate payroll, benefits, access and communication
Separate purchase price, taxes and retained liabilities
Allocate the proposed price among relevant assets and goodwill on a supportable basis, because accounting and tax consequences can differ. Clarify treatment of inventory, VAT, receivables, customer prepayments, warranties and outstanding expenses. Historical tax and business liabilities generally remain important to the owner even when selected assets are sold, while the buyer needs protection against obligations it did not agree to assume. Model the seller's net proceeds and the buyer's acquisition cost before finalising the commercial price. Early Swiss tax advice can prevent a structure that is difficult to reverse later.
- support the allocation among assets and goodwill
- define receivables, prepayments, VAT and retained liabilities
- compare seller and buyer tax consequences before signing
Prepare closing and a customer-focused handover
The closing checklist should cover payments, asset delivery, assignments, consents, permits, records, keys, systems, domains, telephone numbers and evidence of ownership. Coordinate the timing of customer and supplier notices so relationships continue without confusion about invoicing or responsibility. The former owner may provide training and introductions under a defined support arrangement. After closing, the seller still needs to complete accounting, tax, commercial-register and other winding-down steps for the former activity. A detailed plan distinguishes transfer of the operating business from closure of the owner's remaining obligations.
- list each transfer document, consent and physical delivery
- coordinate invoices, customer notices and supplier accounts
- define training and the seller's remaining closure tasks

Frequently asked questions
Can the buyer acquire the name of a sole proprietorship?
The commercial designation, brand and goodwill may be transferable, but the registered name of a sole proprietorship is subject to Swiss naming rules and includes the owner's surname. The buyer should check the intended legal form, commercial-register requirements, trademark rights, domains and how customers will be informed. Do not assume that using the same sign or website automatically gives the buyer the legal right to continue every element of the former business identity.
Do customer contracts transfer automatically?
Not necessarily. Their terms and applicable law determine whether they require assignment, assumption, consent or a new agreement. Some relationships may also depend primarily on the former owner's personal trust. Prepare a contract list and plan customer communication and introductions. Revenue history alone does not prove that future business will continue. The purchase price, handover and any performance-related component should reflect the actual legal and commercial transferability of the customer base.
What happens to employees when the business is sold?
If a business or part of one transfers, Swiss Code of Obligations provisions may govern transfer of employment relationships and information or consultation. The outcome depends on the facts and structure, so obtain legal advice before making commitments. The parties also need to allocate accrued salary, holiday, pension, insurance and other obligations and organise payroll and communication. Employee personal data should be shared only to the extent necessary and with suitable protection during the transaction.
Is selling a sole proprietorship the same as closing it?
No. The sale transfers the agreed operating assets, contracts and rights to the buyer. The owner may still need to collect retained receivables, settle liabilities, complete taxes and accounts, update or cancel registrations and preserve records. Some activities may continue temporarily for transition purposes. The closing checklist should separate what the buyer receives from what the seller must complete personally so neither party assumes that the transaction automatically resolves every historic obligation.
