Everything that matters about accounting outsourcing for e-commerce in Zürich

Whether you run a Sàrl, an SA or a sole proprietorship in Zürich, accounting outsourcing 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 accounting outsourcing

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 Zürich.

The good news: the Swiss frame is stable and predictable. Structure accounting outsourcing once — chart of accounts, document flow, calendar — and the same organisation pays off for years.

Digitalising accounting outsourcing: what actually works

Automation is judged on the exceptions: what happens when the document is unreadable, the supplier unknown, the amount divergent? A good tool isolates those cases and lets a human decide fast — precious for teams in Zürich.

An SME in Zürich that digitalises gains owner time first: less filing, fewer “where is that receipt?” questions, more attention to the trade — that is the real return of accounting outsourcing.

A Swiss SME's accounting calendar

Every deadline has an owner: an obligation “of everyone” is kept by no one. Naming one person per deadline family (VAT, payroll, taxes) closes the gaps.

Delays rarely come alone: neglected bookkeeping postpones the closing, hence the tax return, hence the recalculated instalments — and the business flies blind for months. Keeping the books current as you go is the only sustainable way to hold every cascading deadline.

Meeting in a bright conference room

Outsource accounting outsourcing 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 accounting outsourcing lowers fees more surely than any negotiation.

A business in Zürich can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — accounting outsourcing splits very well.

Zürich: what changes, what does not

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

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

Frequently asked questions

How long must records related to accounting outsourcing be kept?

Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Zürich can therefore archive fully digitally.

What are the current Swiss VAT rates?

Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Zürich.

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 Zürich, 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 Zürich too.
