Accounting outsourcing in Switzerland in Lausanne without the stress: how it works

Accounting outsourcing in Switzerland in Lausanne rests on three pillars: federal law that applies across Switzerland, cantonal deadlines worth knowing, and tools that eliminate re-keying. This guide puts it all in order, fact by fact.

The Swiss legal frame for accounting outsourcing

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. Accounting outsourcing sits squarely within this frame, including for companies based in Lausanne.

One simple principle drives accounting outsourcing: 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 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.

For accounting outsourcing, the internal-external duo works when both sides see the same file: same entries, same documents, same deadlines. Misunderstandings are born from parallel copies.

Digitalising accounting outsourcing: 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 accounting outsourcing: a single inbox (e-mail, scan, photo) and one simple rule — no document sits more than a few days without a proposed entry.

A Swiss SME's accounting calendar

An accounting calendar only lives if it is shared: owner, in-house bookkeeper and fiduciary must see the same deadlines and the same status — the rule holds for every SME in Lausanne.

For accounting outsourcing, year-end is prepared in October: last invoices, investment decisions, provisions to assess — December is too late to act, January is for recording.

Lausanne: what changes, what does not

Working with a fiduciary from Lausanne no longer depends on geography: the documents of a business in Lausanne are shared online, while the canton Vaud keeps its own deadlines for the tax return.

Federal deadlines do not move in Lausanne: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1000 changes nothing about those rules, only the sender's address.

Frequently asked questions

Do you need a fiduciary for accounting outsourcing, or can you do it yourself?

Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Lausanne.

What is simplified bookkeeping and who can use it?

Sole proprietorships and partnerships under CHF 500,000 of revenue may limit themselves to recording income, expenses and assets (art. 957 para. 2 CO). Once over the threshold — or upon founding a Sàrl or an SA — full accounts with balance sheet, income statement and notes become mandatory. The CHF 500,000 threshold is assessed the same way in Lausanne.

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 Lausanne can therefore archive fully digitally.

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 Lausanne as everywhere in Switzerland.
