Accounting automation guide in Mülligen: the practical guide
Whether you run a Sàrl, an SA or a sole proprietorship in Mülligen, accounting automation eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.
Digitalising accounting automation: 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.
Migrate in stages: supplier invoices first (high volume, immediate gain), then receivables with the QR-bill, finally payroll and the closing. At each stage, comparing one month before/after is enough to prove the gain — no theoretical promises needed.
A well-structured SME chart of accounts
The test of a good chart of accounts is a single question: can the owner find the margins in three clicks? If not, the chart serves the tax office but not the business — even in Mülligen.
For a business in Mülligen, the Sterchi/Käfer structure also eases benchmarking: banks and fiduciaries reason on those standard classes to situate an SME's accounting automation.
Outsource accounting automation or keep it in-house?
Splitting roles clearly avoids duplication: the company captures documents and approves payments; the fiduciary checks postings, closes the year and defends the file before the authorities. Each side does what it does best — and nobody keys the same invoice twice.
In Mülligen, as everywhere, the right collaboration rhythm follows the activity: monthly for payroll and data entry, quarterly for VAT, yearly for the closing and tax advice.

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.
A business in Mülligen can collect by QR-bill even without sophisticated software: what matters is that every incoming payment finds its invoice, manually or automatically.
Mülligen: what changes, what does not
Working with a fiduciary from Mülligen no longer depends on geography: the documents of a business in Mülligen are shared online, while the canton Aargau keeps its own deadlines for the tax return.
Federal deadlines do not move in Mülligen: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 5243 changes nothing about those rules, only the sender's address.
Frequently asked questions
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.
Does MyFiducia.ai work for a business based in Mülligen?
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 Mülligen 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 Mülligen, family allowances follow the canton's rates.
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.
