QR-bill invoicing for Sàrl companies in Lengnau (BE): the practical guide
Swiss accounting law (art. 957 ff. of the Code of Obligations) sets a precise frame, yet day-to-day practice often stays fuzzy. This guide walks through what actually matters for a business based in Lengnau (BE).
Digitalising QR-bill invoicing: what actually works
Accounting digitalisation always follows the same path: capture documents at the source (photo or PDF upload), let automatic recognition extract supplier, amount, date and VAT, approve the proposed entries, then archive each document linked to its entry. Every step removes a re-keying — and therefore an error source.
An SME in Lengnau (BE) that digitalises gains owner time first: less filing, fewer “where is that receipt?” questions, more attention to the trade — that is the real return of QR-bill invoicing.
A well-structured SME chart of accounts
The same chart serves three readings: accounting (accuracy), tax (accepted adjustments) and management (margins by activity). Modern software produces all three views without double entry.
For a business in Lengnau (BE), the Sterchi/Käfer structure also eases benchmarking: banks and fiduciaries reason on those standard classes to situate an SME's QR-bill invoicing.
QR-bills and friction-free collections
Since 30 September 2022, the QR-bill has fully replaced the old Swiss payment slips. The Swiss QR Code carries the IBAN (or QR-IBAN), the amount, the debtor and a structured reference: enough to match every incoming payment to its invoice automatically.
Used properly, the QR reference removes most manual debtor ticking. For QR-bill invoicing, that means reminders triggered on reliable data and continuously readable cash flow — no more waiting for month-end to know who has paid.

The Swiss legal frame for QR-bill invoicing
Whether a business sits in Lengnau (BE) or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for QR-bill invoicing. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
Also worth knowing: accounts may be drawn up in the currency most relevant to the business; if that is not the franc, values must additionally be stated in CHF (art. 958d para. 3 CO). Internationally active companies gain books that match their economic reality.
Lengnau (BE): what changes, what does not
Sole proprietorship, Sàrl or SA in Lengnau (BE): the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Bern.
Lengnau (BE) requires no special bookkeeping: the Code of Obligations applies at postal code 2543 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
What are the current Swiss VAT rates?
Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Lengnau (BE).
Does MyFiducia.ai work for a business based in Lengnau (BE)?
Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Lengnau (BE) manages its documents, VAT and exports exactly as anywhere in Switzerland.
Do you need a fiduciary for QR-bill invoicing, or can you do it yourself?
Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Lengnau (BE).
What are the legal obligations for QR-bill invoicing in Switzerland?
The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Lengnau (BE): federal law applies.
