Why SMEs change their name or rebrand
A rebranding or change of company name is not simply a logo refresh: in Switzerland it affects legal identity, commercial visibility, existing contracts, and consistency of accounting data. SMEs face this decision when they adopt a new market positioning, expand beyond their canton of origin, merge operations, or want to move away from an outdated or overly generic name.
The fundamental distinction is between trade name (the name used in the market, often different from the company name) and company name (the name registered in the Commercial Register, binding under the articles of association). A rebranding may be limited to the first case; a formal change of the company requires statutory amendments, publication, and updates across all administrative registers.
This guide summarises costs, timelines, and accounting impacts for entrepreneurs and trustees, with references to federal law (Code of Obligations) and cantonal and federal authority practices updated for 2026.
Commercial rebranding vs change of company name
Before estimating costs, it is worth clarifying which path applies to your situation:
Commercial rebranding
This involves adopting a new brand name, tagline, visual identity, and communication channels while keeping the company name registered in the Commercial Register unchanged. The trade name can be registered separately if it differs from the legal name.
Costs are primarily for marketing, design, and updating materials. No mandatory statutory amendment is required, but take care not to create confusion on invoices, contracts, and official communications.
Change of company name
Formal change of the company name (GmbH, AG, general partnership, or other registered legal forms). For GmbH and AG, this requires a resolution of the shareholders' meeting or general meeting, a notarial deed amending the articles of association, and registration with the Commercial Register of the canton of domicile.
The UID number remains unchanged, but all official documents — articles of association, company stamp, compliant invoices, contracts — must reflect the new name. Existing contracts remain valid for legal continuity, unless clauses require formal notification.
Legal procedure for changing the company name
For a GmbH or AG, the typical process follows the Code of Obligations (CO): verification that the new name is available (it must be distinctive, truthful, and compliant with cantonal rules), resolution by the competent body, drafting of the deed amending the articles of association before a notary, and filing with the cantonal Commercial Register office.
The name must indicate the legal form (e.g. "GmbH" or "AG") and, where required, the corporate purpose. Some cantons check for confusion with names already registered; a preliminary check avoids rejections and repeated costs. Publication in the Swiss Official Gazette of Commerce (SOGC) makes the change enforceable against third parties.
For sole proprietorships or general partnerships, the procedure is simpler but still requires registration or annotation in the Commercial Register and updates with the tax office and social security (AVS). In the case of a merger or acquisition involving a name change, assess whether a simple statutory amendment or a corporate reorganisation with separate valuation and tax impacts is preferable.
Indicative costs by type of intervention
Costs vary by canton, statutory complexity, and the professional support chosen. The figures below are indicative for SMEs in 2026:
| Cost item | Commercial rebranding only | Change of company name (GmbH/AG) |
|---|---|---|
| Legal advice / name check | CHF 500–1'500 | CHF 1'000–3'000 |
| Notary (articles amendment) | — | CHF 800–2'500 |
| Cantonal register fees + SOGC | CHF 0–300 (if registering trade name) | CHF 200–500 (statutory amendment and cantonal charges) |
| Trademark search and filing (IGE) | CHF 350–450 (up to 3 Nice classes; + optional advice) | CHF 350–450 (up to 3 Nice classes; + CHF 100 per additional class from the fourth) |
| Design, website, materials | CHF 3'000–15'000+ | CHF 2'000–10'000 |
| Accounting and software updates | CHF 200–800 | CHF 500–2'000 |
| Third-party notifications (bank, clients, suppliers) | Internal / minimal | CHF 500–1'500 (internal time + any mailings) |
| Indicative total | CHF 4'000–18'000 | CHF 5'000–20'000 |
Legal and register costs are deductible as operating expenses if linked to commercial activity. Design and marketing campaign expenses typically fall under advertising or selling costs. Document each item with an invoice and a clear description for year-end closing and any audit by the statutory auditor.
Trademarks, domains, and protecting the new name
Registration in the Commercial Register does not automatically protect the name as a trademark. To safeguard the distinctive sign in Switzerland, a filing with the Swiss Federal Institute of Intellectual Property (IGE) is required, selecting the relevant Nice classes (e.g. class 35 for commercial services, class 42 for software). The federal filing fee covers up to three classes for ten years; each additional class from the fourth onwards incurs an extra cost. A prior-art search before filing reduces the risk of oppositions and costly brand rollbacks.
Also check domain availability (.ch and, if relevant, .com), social media profiles, and consistency with any European Union trademarks if you operate across borders. If the old trademark is no longer needed, consider abandonment or assignment to avoid unnecessary maintenance fees and future conflicts.
In the case of licensing or franchising, the contract must be updated explicitly: a simple change of company name does not automatically modify the brand usage rights granted to third parties.
Accounting and administrative transition
From an accounting perspective, a name change does not open a new financial year, but it requires consistency between historical data and future documents:
Accounting software and master data. Update the company name, registered address if changed, logo, and footer in invoice, quote, order, and statement templates. In Accountex and similar systems, centralise the change in the company master data so that printing, exports, and integrations inherit the new name without repeated manual updates.
Balance continuity. Do not create a new customer/supplier account for the same legal entity: the unchanged UID ensures continuity with the Federal Tax Administration (FTA) and the bank. Balance sheet and income statement balances remain in the same accounting entity; note the date of the name change in the notes to the financial statements or an appendix if useful for the audit trail.
Invoicing and VAT. From the date of legal effect (Commercial Register registration), invoices must show the new company name, UID, and, where applicable, VAT number. For legal entities registered in the Commercial Register, updates with the FTA and in the UID register occur automatically following registration; the VAT number remains linked to the same UID. Keep a copy of the SOGC publication for any checks.
Contracts and archived documents. Past documents remain valid under the old name. For clarity, tell clients that "[Old Name] GmbH" now operates as "[New Name] GmbH", same UID. Update payment mandates, direct debits, and general terms and conditions wherever the name is cited as a contracting party.
Staff and social security. Inform the AVS compensation fund, the pension fund (BVG/LPP), accident insurance, and, if applicable, the collective health insurance fund. Employment contracts do not need to be redrafted if the same employer remains, but an addendum mentioning the new company name is good practice.
Operational plan: from decision to go-live
A structured timeline avoids non-compliant invoices and payment disruptions:
| Phase | Key actions | Indicative duration |
|---|---|---|
| 1. Analysis and reservation | Commercial Register, IGE, domain search; budget definition | 2–4 weeks |
| 2. Resolution and notary | Shareholders' meeting, statutory deed, Commercial Register filing | 2–3 weeks |
| 3. Trademark filing | IGE application, opposition monitoring | 3–6 months (protection) |
| 4. Register updates | Automatic UID/FTA update via Commercial Register; bank, AVS, BVG/LPP, cantonal tax authorities | 1–2 weeks |
| 5. Systems and accounting | ERP, document templates, email, digital signatures | 1 week |
| 6. External communication | Clients, suppliers, website, letterhead | In parallel with go-live |
Common mistakes and how to avoid them
Launching marketing before Commercial Register registration
Issuing invoices or concluding contracts under a name not yet registered can lead to disputes and VAT non-compliance. Wait for SOGC publication or temporarily use the previous company name with a "formerly …" reference.
Overlooking contractual clauses
Loans, leasing, bank guarantees, and B2B contracts may require written notice or creditor consent. Check before go-live to avoid technical breaches.
Forgetting the sole proprietor
Those operating as sole proprietorships must update the Commercial Register, bank accounts, and professional insurance policies. Past revenue remains attributed to the same taxpayer (same AVS number), but accounting must reflect the new trade name.
Underestimating the temporary dual track
During the transition, define a single cut-over date for invoices, payroll, and internal reporting. Document any rebranding expenses in the accounting records, separating legal, marketing, and IT items for cost analysis and deductibility.
How Accountex supports the transition
A well-managed change of company name translates into a few administrative clicks and zero discontinuity in the numbers. By updating the company master data in Accountex, footers, logos, and tax details propagate automatically to invoices, VAT entries, and closing reports. Historical transactions remain linked to the same entity, making multi-year comparison and dialogue with the auditor easier.
For fiduciary firms assisting multiple clients with rebranding, duplicating document templates and structured exports simplify communications with authorities and bank reconciliation during the transition period. A single accounting environment reduces the risk of issuing documents with obsolete names after the legal effective date.
