Service vs. Product Invoices in Switzerland — What's the Difference?

Many Swiss invoice templates look identical — whether you're selling software consulting or delivering boxes of screws. Yet service and product invoices differ in several ways that matter for tax and accounting purposes. This article shows you exactly which fields are mandatory, useful, or unnecessary depending on your business type.

What both invoice types have in common

Whether you're selling hours or physical products: the statutory requirements under Swiss law are identical. The Swiss invoice template guide with all required fields lists these in detail. In summary, you always need:

• Name and address of invoicer and recipient
• Invoice date and a consecutive invoice number
• Description of service or goods (type and quantity)
• Price (net or gross, clearly shown)
• VAT rate and amount (if VAT-liable; 8.1 % standard rate, 2.6 % reduced rate, 3.8 % accommodation)
• VAT number of the service provider
• Payment terms including due date
• Bank details (IBAN or QR-IBAN for QR-bills)

Once you're using a QR-bill, additional QR-specific fields apply. The step-by-step guide to creating a Swiss QR-bill covers all the details.

What changes for service invoices

When you sell services, you're selling time, expertise, or a deliverable — not a physical product. This has direct implications for your invoice:

Service description is everything

While a product invoice might say "20 × M8 stainless steel screw" and be done, for services a bare "Consulting" often isn't enough. For VAT settlement, your accountant, and any audits, you must clearly document:

• What work was performed (e.g., "Development of marketing strategy — Phase 1")
• For which period (service period, e.g., 01.06–30.06.2026)
• How many hours or what deliverable (for fixed fees: what's included)

The service period is particularly important: it determines which tax period the service falls into — not the invoice date.

Hourly rate or fixed fee

For time-based billing, this structure works well in your line items:

Item	Description	Hours	Rate CHF/hr	Amount CHF
1	Strategy development	8	150.00	1,200.00
2	Revision round	2	150.00	300.00
	Subtotal net			1,500.00
	VAT 8.1 %			121.50
	Total			1,621.50

For a fixed project fee, replace the hours column with a single line item with a clearly defined scope.

Payment terms and early payment discounts

Service providers often use 30-day net terms, sometimes with discounts for early payment. Be precise: "Due 23.08.2026 net; 2 % discount if paid by 07.08.2026."

What changes for product invoices

Physical products require fields that don't exist in pure service invoices.

Quantity, unit, and article number

A product invoice's line items are much more structured:

Article No.	Description	Qty	Unit	Unit Price CHF	Total CHF
4711	Screw M8 × 20, stainless steel	500	Pc.	0.12	60.00
4820	Washer M8	500	Pc.	0.05	25.00

Unit (piece, kg, litre, metre) and unit price are non-negotiable for goods — the buyer will verify delivered quantities against the delivery note.

Delivery note reference and delivery date

Product shipments usually come with a delivery note. Your invoice should reference the delivery note number and date, so the buyer's accounting and warehouse can reconcile the documents. It's not legally required, but it prevents questions and payment delays.

Packaging, shipping, and customs

Is freight charged separately? Show it as its own line item — including any VAT. For shipments abroad, Swiss VAT is waived; instead you may need an export declaration and a note referencing the zero rate (export supply under VAT Act Article 23).

Check for reduced VAT rates

Food, books, and certain agricultural products qualify for the reduced 2.6 % rate. For product invoices with mixed items (e.g., a grocery delivery), you must show the correct rate per line and total the amounts separately.

Hybrid case: labour and materials

Many SMEs invoice both — a trades business bills labour and materials; an IT firm bills software licences and setup work. Here's how:

1. Separate service and product lines clearly in your line items.
2. Check the VAT rate per line: materials and labour can have different rates (e.g., accommodation service 3.8 % + meals 2.6 %).
3. Show VAT totals separately if different rates apply — this is mandatory under VAT law.

Common mistakes by invoice type

Service invoices:

• Missing service period → unclear tax period
• Fixed fee without service description → accountant asks for details
• No mention of applicable law for international clients

Product invoices:

• Missing unit → impossible to verify quantities
• Wrong VAT rate on reduced goods
• No delivery note number → payment delayed at buyer's end

Quick reference

• Statutory required fields are identical for services and products.
• Service invoices need detailed service descriptions and the service period.
• Product invoices need article numbers, quantities, units, and usually a delivery note reference.
• For mixed invoices: check VAT rates per line and show them separately.
• Export shipments: Swiss VAT is waived; export declaration required.
• A good template at snapbill.ch handles both types cleanly — and prevents errors before they start.
