QR-bill invoicing for construction companies in Untersiggenthal without the stress: how it works

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 Untersiggenthal.

Digitalising QR-bill invoicing: what actually works

Security is part of digitalisation: named access, tested backups, encryption of sensitive data. A digital accounting file is protected like a safe — because it is one.

The winning pair for QR-bill invoicing: a single inbox (e-mail, scan, photo) and one simple rule — no document sits more than a few days without a proposed entry.

The Swiss legal frame for QR-bill invoicing

Swiss accounting law has been unified in the Code of Obligations since 2013: the same bookkeeping rules (art. 957a CO) and retention rules (art. 958f CO — 10 years for books, vouchers and reports) apply regardless of legal form. QR-bill invoicing sits squarely within this frame, including for companies based in Untersiggenthal.

One simple principle drives QR-bill invoicing: every franc in or out must be explainable by a document, an entry and an account. All of Swiss accounting law fits inside that traceability requirement.

Outsource QR-bill invoicing or keep it in-house?

A fiduciary's cost depends first on the quality of the data received: digitised, filed, reconciled documents are processed fast; a box of loose receipts is billed by the hour. Improving the internal preparation of QR-bill invoicing lowers fees more surely than any negotiation.

For QR-bill invoicing, a quarterly 30-minute check-in with the fiduciary beats an annual marathon: questions get handled while they are small.

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.

For the debtors of a business in Untersiggenthal, nothing changes on the payer's side: scan the code, confirm, pay. On the QR-bill invoicing side, everything changes: the collection entry proposes itself, the receivables ledger updates continuously and reminders go out on exact balances.

Untersiggenthal: what changes, what does not

Sole proprietorship, Sàrl or SA in Untersiggenthal: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Aargau.

For a business in Untersiggenthal, that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Aargau.

Frequently asked questions

When must a business register for VAT?

As soon as its worldwide annual turnover reaches CHF 100,000 (CHF 250,000 for non-profit sports or cultural associations). Below that, voluntary registration remains possible and often makes sense to reclaim input VAT on investments. The threshold is federal: it applies in Untersiggenthal as everywhere in Switzerland.

Does MyFiducia.ai work for a business based in Untersiggenthal?

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 Untersiggenthal manages its documents, VAT and exports exactly as anywhere in Switzerland.

Which social contributions does a Swiss employer pay?

AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in Untersiggenthal, family allowances follow the canton's rates.

When is entry in the commercial register mandatory?

A Sàrl and an SA only come into existence with their registration. A sole proprietorship must register from CHF 100,000 of annual revenue; below that, registration stays voluntary but adds credibility and protects the business name. Registration goes through the canton's commercial register office — for Untersiggenthal too.
