Everything that matters about QR-bill invoicing for associations in Mülligen

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 Mülligen.

Digitalising QR-bill invoicing: what actually works

Access for the fiduciary, the auditor and employees is set by roles: view, enter, approve, close. Well-set rights protect the data and speed up collaboration.

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

In Switzerland, the duty to keep accounts stems from art. 957 ff. of the Code of Obligations. Legal entities (Sàrl, SA) and sole proprietorships with at least CHF 500,000 in revenue keep full accounts: balance sheet, income statement and notes. Below that threshold, a simplified record of income, expenses and assets is sufficient.

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.

A well-structured SME chart of accounts

Nearly all Swiss SMEs rely on the standard SME chart of accounts (Sterchi/Käfer): classes 1 (assets) to 9 (closing), with revenue in class 3 and expenses in classes 4 to 6. Using this standard structure makes conversations with your fiduciary, auditor and tax administration far easier.

In an SME in Mülligen, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.

QR-bills and friction-free collections

Clear payment terms, a visible due date, exact details: half of late payments come from ambiguous invoices, not bad payers — the finding holds in Mülligen too.

For QR-bill invoicing, invoicing fast changes everything: a service billed the week it is delivered gets paid noticeably earlier than a month-end batch invoice.

Mülligen: what changes, what does not

Mülligen (postal code 5243, canton Aargau) applies the same federal rules as the rest of the country: what changes in Mülligen are the cantonal counterparts — tax administration, compensation office, commercial register.

Mülligen requires no special bookkeeping: the Code of Obligations applies at postal code 5243 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

Frequently asked questions

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 Mülligen too.

What is the difference between a limited and an ordinary audit?

The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Mülligen as anywhere.

Can QR-bill invoicing be automated with AI?

Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches QR-bill invoicing.

Which documents should be prepared for the year-end closing?

Bank and cash statements at the closing date, the inventory of stock and work in progress, final AHV/LPP/accident settlements, contracts signed or amended during the year, invoices straddling two years and the detail of accruals. With an up-to-date document archive, most of it is already there. The list is identical in Mülligen: the CO dictates it, not the commune.
