What is an invoice and why do you need one?
invoice is more than just a request for money. It is a time-stamped commercial document that records a transaction between a buyer and a seller.
Unlike a receipt (which proves payment happened), an invoice establishes an obligation to pay. It details exactly what goods or services were provided, the agreed prices, and the payment terms.
For freelancers and businesses, the invoice is the heartbeat of cash flow. Without it, there is no formal record of the debt owed to you, making it difficult to get paid or claim legal recourse.
Get Paid Faster
Professional invoices with clear due dates and payment methods (like IBANs) significantly reduce payment delays compared to informal requests.
Legal Protection
An invoice acts as a legally binding agreement. If a client refuses to pay, a signed or accepted invoice is your primary evidence in small claims court.
Tax Compliance
To reclaim VAT or deduct expenses, tax authorities require valid invoices. Missing or incorrect invoices can lead to fines during an audit.
Key Elements of a Professional Invoice
A standard invoice isn't just a request for payment—it's a legal document. Ensure every invoice you generate includes these six essential components.
Professional Header
Your business logo and clear 'INVOICE' label establish immediate brand identity and document purpose.
Seller & Client Details
Full legal names, addresses, and VAT/Tax IDs for both parties are mandatory for tax deduction compliance.
Unique Identifiers
A sequential invoice number (e.g., INV-001) and issue date are crucial for audit trails and tracking.
Clear Line Items
Break down services or products by quantity, unit rate, and net amount to avoid client disputes.
Tax Breakdown
Transparently display the Net Total, VAT/Tax Rate, Tax Amount, and final Gross Total.
Payment Terms
Explicitly state the due date and payment method (IBAN, Bank Details) to ensure faster payment.

How to Get Paid Faster in Switzerland
Professional invoicing isn't just about compliance. Use these country-specific tips to improve cash flow and maintain great client relationships.
Set Clear Payment Terms
In Switzerland, 30 days is the standard default. For smaller services, 10 or 20 days is also common. "QR-bills" are now the standard for efficient payment processing.
Offer Multiple Payment Methods
Remove friction. Include your Bank Details (IBAN/SWIFT) directly on the invoice so clients can pay immediately.
Itemize Clearly
Avoid generic descriptions like 'Services'. Break down costs line-by-line to prevent client disputes and delays.
Verify Tax IDs
Ensure you include the UID (Unternehmens-Identifikationsnummer) for B2B clients. It typically looks like CHE-123.456.789 MWST.
Chase Late Payments
Don't be afraid to follow up. Send a polite reminder email 2-3 days before the due date, and immediately after it passes.
Keep Consistent Records
Swiss law (Code of Obligations) requires business records and correspondence to be kept for 10 years. Digital archiving is permitted if integrity is guaranteed.
