Einzahlungsschein QR Rechnung: What Changed for Swiss SMEs

The Transition from Einzahlungsschein to QR-Rechnung

Until September 2022, invoicing a client in Switzerland required pre-printed paper slips supplied by banks or PostFinance. Businesses had to manage two separate formats: the red slip for basic transfers without a reference number, and the orange slip (ESR/PVR) for structured 27-digit payment references. This meant keeping cartons of pre-printed stationery in stock, aligning printer margins to the exact millimetre, and dealing with optical character reading issues when slips were damaged or misaligned.

When SIX and PostFinance discontinued the old paper system, the move from the classic Einzahlungsschein to QR-Rechnung became mandatory across Switzerland. The transition eliminated proprietary stationery overnight. Today, the Swiss QR payment section prints on standard white A4 paper or attaches directly to an electronic PDF invoice sent by email. For an independent electrician in Zurich or a building contractor in Winterthur, this shift significantly lowered administrative overhead and virtually eliminated manual data entry errors by customers.

Technical Layout: Einzahlungsschein vs. QR-Rechnung Requirements

Unlike the legacy payment slips, the QR-bill integrates all payment information into a unified section at the bottom of the page. This area is divided into two distinct zones structured according to strict SIX payment standards:

• Receipt section on the left (62 mm wide by 105 mm high): Contains the payable-to account details, customer address, currency, and exact amount. It functions as the physical confirmation receipt for counter payments at the post office branch.
• Payment part on the right (148 mm wide by 105 mm high): Houses the 46 by 46 mm Swiss QR Code with the Swiss cross in the center, flanked by human-readable payment details including the account number, reference, and payable-by details.
• Separation line: When sent as a physical paper invoice, the payment slip must feature a perforation or a solid line with scissors symbols to enable clean detaching.
• Reference structures: The former orange ESR reference is replaced by the 27-digit QR reference (used exclusively with a dedicated QR-IBAN) or the international ISO 11649 Creditor Reference (used with a standard IBAN).

Flexibility in payment amounts is another structural change. The old orange slips strictly prohibited manual corrections or blank amount fields. Under the current QR standard, businesses can generate payment sections with a blank amount field when necessary, such as for variable service deposits or voluntary contributions. However, standard commercial billing requires an exact total specified in CHF or EUR with two decimal places.

Mandatory Invoice Details and Current Swiss VAT Rates

While the Swiss QR code automates payment processing, it does not replace the commercial and legal requirements established by the Federal Act on Value Added Tax (MWSTG, Art. 26). A QR-bill must still function as a complete, audit-compliant invoice containing specific business information above the payment slip.

Your invoice header must clearly display your full registered legal entity name, complete company address, and your Swiss Business Identification Number (UID/IDE) including the VAT suffix (e.g., CHE-123.456.789 MWST). Invoices must also apply the current Swiss VAT rates that took effect on January 1, 2024:

• Standard rate (8.1%): Applies to most craft services, plumbing installations, consulting, repairs, and general trade goods.
• Reduced rate (2.6%): Covers basic necessities, foodstuffs, books, and agricultural supplies.
• Special rate for accommodation (3.8%): Applies directly to overnight lodging services.

Every tax rate applied must appear alongside its specific taxable base amount and the calculated VAT sum. The invoice body must outline the exact scope of services delivered, the completion dates of the work, and the client full legal name and billing address. Inconsistencies between the invoice header and the QR code payload can cause input tax deduction rejections during a Federal Tax Administration (ESTV) audit.

Automated Reconciliation Using ISO 20022 camt Files

The retirement of the Einzahlungsschein coincided with the Swiss banking sector complete migration to ISO 20022 messaging standards. The legacy V11 text files used for orange slip ESR reconciliations were replaced by standardized XML formats, specifically camt.053 and camt.054.

Swiss banks and PostFinance generate camt.054 files to deliver structured, itemized credit notifications, while camt.053 files serve as comprehensive electronic account statements. When you upload these files into your billing software, incoming payments match automatically with open customer accounts using the 27-digit QR reference. This eliminates manual line-by-line bank statement reviews.

When a customer misses your standard payment window, usually set at 30 days, managing overdue balances is straightforward. If an outstanding balance of CHF 4'500.00 remains unpaid past its due date, the debtor enters default under the Swiss Code of Obligations. According to Art. 104 CO, a creditor is entitled to claim statutory default interest of 5% per year from the date of default, unless your commercial contract specifies a different rate. Reliable invoicing systems calculate these accrued interest charges accurately within formal reminder notices.

Managing Daily Invoicing Without Administrative Friction

For sole proprietors, installers, and independent contractors, the end of the old slip system raised concerns about software complexity. In practice, staying fully compliant with SIX standards, Swiss VAT rules, and ISO 20022 reconciliation does not require bulky enterprise software suites.

Using a mobile-friendly invoicing web application allows you to issue quotes, convert them into compliant QR invoices on-site right after finishing a job, and send clean PDF documents directly to your customer. Faster invoicing shortens your payment cycles and keeps your cash flow steady.
