Accounting outsourcing required documents in Mex (VD): rules, deadlines, best practice

Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on accounting outsourcing in Mex (VD): what the law requires, what can be automated, and when to delegate.

The Swiss legal frame for accounting outsourcing

For an owner in Mex (VD), the question is never “do we need accounts?” but “at what level of detail?”. The CO sets the floor; the bank, the tax office and the shareholders set the rest.

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

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 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 Mex (VD).

For accounting outsourcing, 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

Companies exceeding two of three thresholds for two consecutive years — CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions — move to an ordinary audit. Below that, the limited audit applies, and companies with no more than ten full-time positions on annual average can opt out with the consent of all shareholders.

The timetable is tight: accounts drawn up and approved by the general meeting within six months of the year-end. For accounting outsourcing, chasing missing documents from January (bank statements, contracts, insurance settlements) avoids the last-minute sprint and auditor reservations.

Mex (VD): what changes, what does not

Sole proprietorship, Sàrl or SA in Mex (VD): the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Vaud.

Federal deadlines do not move in Mex (VD): VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1031 changes nothing about those rules, only the sender's address.

Frequently asked questions

How much does accounting outsourcing cost in Mex (VD)?

It depends on document volume, the number of salaries and VAT complexity — no serious figure can be quoted without examining the file. Two levers cut the bill everywhere: digitised, well-filed receipts and software that prepares entries instead of having them re-keyed.

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 Mex (VD): the CO dictates it, not the commune.

Does MyFiducia.ai work for a business based in Mex (VD)?

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 Mex (VD) manages its documents, VAT and exports exactly as anywhere in Switzerland.

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 Mex (VD) as everywhere in Switzerland.
