Fiduciary services for e-commerce in Füllinsdorf: the practical guide
Whether you run a Sàrl, an SA or a sole proprietorship in Füllinsdorf, fiduciary services eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.
The Swiss legal frame for fiduciary services
Responsibility for the books is personal: in an SA, organising the accounting is one of the board's non-transferable duties (art. 716a CO); in a Sàrl, the managing directors carry the same duty. Outsourcing the execution never transfers that underlying responsibility, including for a company based in Füllinsdorf.
The law also settles the form: accounts may be kept in a national language or in English, on paper or electronically (art. 957a para. 5 CO). That pragmatism lets fiduciary services run entirely on digital tools — no paper binder is required.
Digitalising fiduciary services: what actually works
Artificial intelligence has changed the economics of fiduciary services: automatic invoice reading reaches recognition rates that make manual entry marginal, and posting suggestions learn from corrections. The accountant does not disappear — the job shifts from data entry to control and advice.
For fiduciary services, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.
A Swiss SME's accounting calendar
The professionals' trick: handle every deadline at D-30, not D-1. A VAT return prepared a month early leaves time to chase a missing document without penalty.
For fiduciary services, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.

Year-end closing: how the mechanics work
Accrual accounting is the technical heart of the closing: every income and every expense belongs to the year it economically concerns, regardless of the payment date. Rents paid in advance, insurance premiums straddling the date, supplier invoices arriving in January: all flow through accrual accounts.
For fiduciary services, a closing checklist reused every year transforms the exercise: same steps, same checks, same documents — only the year changes.
Füllinsdorf: what changes, what does not
Füllinsdorf (postal code 4414, canton Basel-Country) applies the same federal rules as the rest of the country: what changes in Füllinsdorf are the cantonal counterparts — tax administration, compensation office, commercial register.
Federal deadlines do not move in Füllinsdorf: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4414 changes nothing about those rules, only the sender's address.
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 Füllinsdorf too.
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 Füllinsdorf, family allowances follow the canton's rates.
