Writing Quotes for Swiss Tradespeople: Guide & Tips

The Problem with Vague Price Estimates

Your workday on-site is done, the van is loaded, and the tools are put away. Back at the workshop or your desk, you face three pending quote requests: a bathroom renovation in Zurich, custom window supply in Bern, or an exterior paint job in Lausanne. Sending a rough estimate via text might save you twenty minutes now, but it exposes your business to eroded margins and bitter client disputes later. In Switzerland, a quote isn't just a ballpark figure; it's often a binding agreement.

Your work – creating quotes for tradespeople – demands precision. Structuring the document correctly protects you financially and defines clear boundaries from day one, adhering to Swiss law. Let's look at how to avoid headaches and ensure you get paid fairly.

Fixed Price vs. Cost Estimate Under Swiss Law

In common talk, terms like 'quote', 'fixed price' (Pauschalpreis), and 'cost estimate' (Kostenvoranschlag) are often used interchangeably. Swiss law, however, treats them very differently, especially concerning who bears the financial risk of unforeseen issues on site.

A fixed-price quote binds the tradesperson strictly to the stated amount. If structural challenges require eight extra hours of work or if raw material prices surge mid-project, the loss falls directly on your margin. Conversely, a cost estimate serves as a technical guideline. According to Article 375 of the Swiss Code of Obligations, if a tradesperson disproportionately exceeds an estimate without prior notification to the client, the client has the right to reduce payment or terminate the contract. Swiss jurisprudence generally considers a deviation of 10% to 15% as disproportionate.

To prevent disputes, clearly state on your document whether the price is a fixed lump sum (Festpreis / Pauschale), billed based on actual time and materials (nach Aufwand / Regie), or an indicative estimate subject to technical tolerances.

Writing Quotes for Tradespeople: An Essential Checklist

A transparent quote removes ambiguity, builds trust, and speeds up client decisions. To comply with Swiss business standards, every quote you issue should contain distinct structural elements:

• Full company header: registered company name, legal form (Sole Proprietorship, AG, GmbH), physical address, phone, email, and Swiss Business Identification Number (IDE/UID).
• Client details and site address: billing address alongside the exact location of the property or site where the work will be carried out.
• Date of issue and validity period: an explicit expiry date (e.g., 30 days) to protect your business from sudden supplier price increases.
• Detailed line items: a clear breakdown separating work phases, estimated hours, material quantities, and specific technical or brand details.
• Subtotals, VAT, and gross totals: clear separation of taxable net amounts, the applicable Swiss VAT rate (standard 8.1%, reduced 2.6%, or 3.8% for specific services), and the final gross total in Swiss Francs (CHF).
• Payment deadlines and deposits: payment terms (typically 30 days net), any deposits required before material ordering, or payments based on work progress for larger projects.
• Regie rates and conditions: standard hourly rates for extra-contractual work, travel allowances, and reference to your General Terms and Conditions (AGB).

If your Swiss business generates an annual taxable turnover below CHF 100,000, you are generally exempt from mandatory VAT registration. In this case, do not state VAT percentages or amounts; instead, include the note: 'VAT exempt according to Art. 10 of the Swiss VAT Act (VATA)'.

Calculating Prices and Labour Rates Without Losing Margin

One of the most common mistakes among independent tradespeople is pricing jobs by adding a small markup to wholesale material costs and guessing labour hours. An electrician charging CHF 115 per hour and forgetting travel, tool depreciation, and waste disposal will struggle to maintain a positive operating cash flow.

Your hourly rate must cover not only your net salary but also overhead costs: workshop rent, vehicle leasing, professional insurance, association fees, and non-billable administrative hours spent on purchasing and invoicing. Materials bought in bulk must carry a markup to cover order logistics, warehouse storage, and warranty responsibility for installed components.

Managing Variations and Extra Work on Swiss Sites

During renovation or repair work, unforeseen issues are common. A client might request additional electrical outlets, or opening up a floor might reveal rotten structures. Accepting extra work verbally while covered in dust is a recipe for payment delays once the final invoice arrives.

Every time additional work arises, pause the specific task. Send a brief written confirmation or an addendum quote via email outlining the extra scope, estimated hours, materials, and price (fixed or by Regie). Requesting written client approval before proceeding protects your right to bill for the extra hours under Swiss law, without argument.

From Accepted Quote to Compliant Swiss QR-Bill

Once your client approves the quote, the administrative workflow should proceed seamlessly without manual re-entry. Rewriting line items from a spreadsheet or Word template into an invoice wastes non-billable hours and invites transcription errors.

In Switzerland, standard invoicing requires a SIX-compliant QR-bill section. A smartphone-accessible system allows you to convert an approved quote into a final QR invoice with a simple tap, applying current VAT rates (8.1%, 3.8%, or 2.6%). If payments exceed the net 30-day deadline, you can issue structured reminders applying the legal default interest of 5% (Art. 104 CO), while reconciling incoming bank payments via camt.053 or camt.054 files.
