Advisor handing a document and pen to a client

E-invoicing for architecture firms in Avusy without the stress: how it works

Whether you run a Sàrl, an SA or a sole proprietorship in Avusy, e-invoicing eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.

Digitalising e-invoicing: what actually works

Digitising does not mean hoarding PDFs: without the document-entry link, a digital file is as opaque as a box of archives — true in Avusy as everywhere.

For an owner in Avusy, 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 e-invoicing

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. E-invoicing sits squarely within this frame, including for companies based in Avusy.

For e-invoicing, the classic early mistake remains mixing private and business: a dedicated bank account and documented private withdrawals eliminate half the discussions with the tax office.

Outsource e-invoicing or keep it in-house?

Responsibility stays with the client: the fiduciary executes with care, but the signed accounts bind the company. Understanding what you sign is not optional.

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

QR-bills and friction-free collections

Instalments and partial payments are handled cleanly with distinct references per tranche: each collection finds its share, and the remaining balance stays correct at all times.

For e-invoicing, the share of collections matched automatically is a metric worth watching: when it drops, it is almost always a matter of misused references.

Avusy: what changes, what does not

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

Federal deadlines do not move in Avusy: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1285 changes nothing about those rules, only the sender's address.

Frequently asked questions

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 Avusy: the CO dictates it, not the commune.

Does MyFiducia.ai work for a business based in Avusy?

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 Avusy manages its documents, VAT and exports exactly as anywhere in Switzerland.

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 Avusy, family allowances follow the canton's rates.

What is the difference between a limited and an ordinary audit?

The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Avusy as anywhere.
