Online accounting for the self-employed in Perroy explained simply
Whether you run a Sàrl, an SA or a sole proprietorship in Perroy, online accounting eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.
Digitalising online accounting: what actually works
Artificial intelligence has changed the economics of online accounting: 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 an owner in Perroy, a dashboard only has value if the data is fresh: automating data entry means, first of all, buying up-to-date information about your own business.
The Swiss legal frame for online accounting
Three documents summarise the health of a Swiss business: the balance sheet (what it owns), the income statement (what it earns) and the notes (what else you should know). All the work of online accounting converges on those three pages, in Perroy too.
The good news: the Swiss frame is stable and predictable. Structure online accounting once — chart of accounts, document flow, calendar — and the same organisation pays off for years.
A well-structured SME chart of accounts
A good chart of accounts tells the story of the business: classes 1 and 2 describe what it owns and owes, class 3 what it sells, classes 4 to 6 what it consumes. Private accounts (sole proprietorships) and shareholder current accounts (Sàrl/SA) must stay spotless: they are the first thing examined in a tax audit.
For online accounting, a few well-chosen analytical accounts (by activity, by site) beat a forest of sub-accounts nobody ever reads.

Outsource online accounting or keep it in-house?
Outsourcing online accounting to a fiduciary frees up time and secures compliance; keeping it in-house preserves a continuous view and costs less in fees. The best answer is often hybrid: the company captures and digitises as it goes, the fiduciary supervises, closes the books and represents the company before the authorities.
For online accounting, a quarterly 30-minute check-in with the fiduciary beats an annual marathon: questions get handled while they are small.
Perroy: what changes, what does not
Perroy (postal code 1166, canton Vaud) applies the same federal rules as the rest of the country: what changes in Perroy are the cantonal counterparts — tax administration, compensation office, commercial register.
Perroy requires no special bookkeeping: the Code of Obligations applies at postal code 1166 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 Perroy too.
Can online accounting 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 online accounting.
Does MyFiducia.ai work for a business based in Perroy?
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 Perroy manages its documents, VAT and exports exactly as anywhere in Switzerland.
What are the legal obligations for online accounting in Switzerland?
The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Perroy: federal law applies.
