Invoicing Clients in Switzerland: Mandatory Requirements, VAT, and Payment Terms
An invalid Swiss invoice:missing business ID number, incorrectly labeled VAT, or wrong tax base:can delay payment by several weeks and create tax complications for the client. Since January 2024, the standard VAT rate is 8.1% and the special hotel rate is 3.8%. Freelancers and consultants based in Suisse Romande have specific obligations depending on their status (VAT-registered or not) and their clientele (Swiss or foreign). This guide details the structure of a compliant invoice and special cases.
Invoicing in Switzerland follows precise rules, especially once VAT enters the picture. Even a service provider not subject to VAT must respect certain requirements for the invoice to be legally valid and accountable by their client.
- Full name and address of service provider and client.
- Invoice issue date.
- Unique and sequential invoice number.
- Precise description of services provided (nature, quantity, period).
- Gross amount, applicable VAT rate, VAT amount, and total including VAT (if registered).
- Business ID number (CHE-XXX.XXX.XXX) if VAT-registered.
- Payment term or due date.
- Bank details (Swiss or foreign IBAN).
VAT: Rules According to Service Provider Status
A service provider not subject to VAT (annual revenue below 100,000 CHF) is not permitted to charge VAT:even if the client requests it. The invoice must clearly state that the service is VAT-exempt or simply not mention any VAT amount. Mentioning a VAT amount on an invoice without being registered is a violation of Swiss VAT law (LTVA).
For a registered service provider, the invoice must separately show the gross amount, applicable rate, and VAT amount. Since January 1, 2024:
| Type of Service | VAT Rate 2026 |
|---|---|
| Standard services (consulting, IT, marketing...) | 8.1% |
| Common consumer goods, books, medicines | 2.6% |
| Hotel accommodation | 3.8% |
| Medical, educational, cultural services | 0% (exempt) |
Payment Terms and Reminders: Swiss Business Practices
Swiss law does not set a standard legal payment term: the contractual term takes precedence. In the absence of expressly stipulated conditions, Swiss law of obligations (CO) considers the debt immediately due. In practice, the standard term in Swiss commercial transactions is 30 days net.
Large Swiss companies (Nestlé, Novartis, ABB, major banks) often have their own general purchase terms providing 45 to 60 days. A freelancer working with this type of client must account for this in cash flow management. Negotiating a 30% deposit upon order and balance at 30 days is common and acceptable practice with Swiss SMEs.
In case of payment delay, the Swiss creditor can claim default interest of 5% per annum without prior notice from the first day of delay (art. 104 CO). Formal notice (registered letter) remains advisable before any collection proceedings. Swiss collection proceedings (LP) are accessible, relatively quick, and inexpensive: they constitute an effective pressure tool even for small claims.
Cross-Border Invoicing: Foreign Clients from Switzerland
Services invoiced to a client established abroad (France, Germany, EU) are in principle exempt from Swiss VAT if the place of service is deemed to be at the recipient's location (recipient location rule, art. 8 al. 1 LTVA). The invoice should then state: "Service exempt from Swiss VAT:place of service abroad."
The reciprocal applies: a Swiss client receiving a service from a foreign provider must declare this service via the self-assessment procedure. This is not the responsibility of the foreign provider, but it is useful to mention in general terms to avoid questions.
The golden rule in Swiss invoicing: clarity of the document takes precedence over everything else. An invoice that clearly indicates what was delivered, to whom, for what amount, and within what term pays without problems. Payment disputes almost always arise where the service was vague or the amount contestable.
Frequently Asked Questions
What format should be used for the invoice number in Switzerland?
Swiss law does not impose a specific format, but practice recommends an annual sequential number (e.g., 2026-001, 2026-002...) or a continuously increasing number. The important thing is uniqueness and unbroken sequence: a missing number can be interpreted by tax authorities as a concealed invoice. For VAT-registered clients, rigorous numbering is mandatory.
Can you invoice in euros from Switzerland?
Yes, invoicing in foreign currencies (EUR, USD, GBP) is legal in Switzerland. If the service provider is VAT-registered, the VAT amount must be converted to CHF according to the official FTA (Federal Tax Administration) rate on the invoice date. It is advisable to specify the exchange rate used on the invoice to avoid dispute.
What is the legal retention period for invoices in Switzerland?
Accounting documents, including invoices issued and received, must be retained for ten years in Switzerland (art. 958f CO). This period runs from the end of the accounting year in question. The records may be digital provided the documents are readable, intact, and accessible for the entire legal period.
Can a French micro-entrepreneur invoice a Swiss client without Swiss VAT?
Yes, under conditions. A service provider established in France invoicing a Swiss business applies French VAT if the service is deemed to take place in France (for B2C services) or no VAT if the recipient is VAT-registered in Switzerland and the recipient location rule applies. They do not collect Swiss VAT, unless they exceed the Swiss registration threshold (100,000 CHF of annual services to Swiss clients).
