Creating Invoices for Switzerland

Registration Requirements

Since January 1, 2018, foreign companies providing certain services or goods in Switzerland may be required to register for Swiss VAT if their global turnover exceeds CHF 100,000. This applies from the first franc of Swiss turnover. Key points:

• Check if your services/goods trigger a registration requirement
• Register with the Swiss Federal Tax Administration if necessary
• Appoint a fiscal representative in Switzerland if required

Using Swiss VAT Numbers

Once registered, you'll receive a Swiss VAT number. This must be used on all invoices for Swiss transactions. Remember:

• Format: CHE-123.456.789 MWST
• Always include this number on invoices to Swiss customers
• Do not charge Swiss VAT if you're not registered, even if mentioned by mistake (it would still be payable to Swiss authorities)

Currency Considerations

While it's permissible to invoice in foreign currencies, there are some guidelines:

• Clearly state the currency used
• If using a foreign currency, you must convert to Swiss Francs for VAT reporting using official exchange rates
• Consider offering pricing in Swiss Francs to simplify transactions for your customers

Cross-border Services

Special rules apply for cross-border services:

• Many B2B services are subject to the reverse-charge mechanism
• The place of supply determines VAT treatment
• Clearly state "VAT reverse-charged" when applicable
• Certain services (e.g., related to Swiss real estate) may always be subject to Swiss VAT

It serves multiple purposes:

• Simplifies communication with authorities
• Helps identify businesses across different registers
• Used for VAT and other official purposes

Format: CHE-123.456.789

Obtaining a UID Number

• Automatically assigned when registering a business in Switzerland
• Freelancers can request it (guide here)
• Foreign companies get a UID when registering for Swiss VAT
• Can be looked up in the public UID register

Using UID on Invoices

• Always use your full UID number on invoices if you have one
• For VAT purposes, add "MWST" after the number
• You don't need to include your customer's UID on the invoice, but it can be helpful for B2B transactions

Since January 1, 2018, electronic invoices have the same legal status as paper invoices in Switzerland. This includes:

• PDF invoices sent by email
• Structured electronic formats (e.g., XML)
• Online portals where customers can download invoices

Requirements for E-Invoicing

To use e-invoicing in Switzerland:

• Ensure the authenticity of origin and integrity of content
• Both parties must agree to the use of electronic invoices
• Implement a reliable audit trail linking invoices to actual supplies
• Be able to convert e-invoices to readable format if required by authorities

QR-Bill System

Switzerland has introduced the QR-bill system to modernize invoicing:

• Replaces traditional payment slips
• Contains a QR code with all payment information
• Facilitates automated processing and payment
• Mandatory for many types of invoices since 30 September 2022

Implementing QR-bills can streamline your invoicing process for Swiss customers.

Layout Best Practices

While there's no mandatory layout for Swiss invoices, a clear, professional design is important:

• Use your company letterhead
• Clearly separate and label each required element
• Make the total amount and payment details prominent
• Consider using a pre-designed template that includes all required fields

Language Considerations

Switzerland has four official languages: German, French, Italian, and Romansh. Best practices include:

• Use the primary language of your customer's region (invoicing tools like Magic Heidi allow you to select the language of your invoice)
• For national clients, consider bilingual invoices (e.g., German and French)
• Ensure all required elements are clearly understandable regardless of language used

Common Mistakes and Penalties

Typical Invoicing Errors

Watch out for these common mistakes:

• Missing or incorrect VAT number
• Applying the wrong VAT rate
• Failing to clearly state if a supply is exempt or reverse-charged
• Incorrect or missing customer details
• Using inconsistent or duplicate invoice numbers

Consequences of Incorrect Invoices

Incorrect invoicing can lead to:

• Delayed payments from customers
• Rejection of input VAT claims by your customers
• Penalties and interest charges from tax authorities
• Additional administrative burden to correct errors

Correction Procedures

If you discover an error on an issued invoice:

• Issue a corrective invoice or credit note as soon as possible
• Clearly reference the original invoice
• Explain the nature of the correction
• Adjust your VAT returns if necessary

For minor errors, a corrective letter may be sufficient. For major errors, a full credit and re-invoice may be required.

Special Invoicing Situations

Credit Notes and Corrections

When issuing credit notes:

• Clearly label it as a credit note
• Reference the original invoice
• Explain the reason for the credit
• Show the VAT adjustment
• Issue in the same currency as the original invoice

Partial Payments and Installments

For supplies paid in installments:

• Issue an invoice for each installment or a single invoice showing the payment schedule
• Clearly show the due date for each payment
• VAT becomes due on each installment when it's payable

Discounts and Price Reductions

When offering discounts:

• Clearly show the discount amount and percentage on the invoice
• If offering an early payment discount, show the terms clearly (e.g., "2% discount if paid within 10 days")
• Adjust the VAT calculation based on the discounted price

Practical Tips for Compliance

Implement a Robust Invoicing System

Invest in quality accounting software that:

• Automatically includes all required invoice elements
• Supports multiple languages and currencies
• Can generate QR-bills
• Integrates with your VAT reporting process
