E-invoicing for agencies in Au (SG) explained simply

E-invoicing for agencies in Au (SG) raises the same questions for most Swiss SME owners: which obligations apply, which deadlines are running, which documents to prepare. This page covers the federal rules in force — without unnecessary jargon.

Digitalising e-invoicing: what actually works

Accounting digitalisation always follows the same path: capture documents at the source (photo or PDF upload), let automatic recognition extract supplier, amount, date and VAT, approve the proposed entries, then archive each document linked to its entry. Every step removes a re-keying — and therefore an error source.

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.

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 Au (SG) 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

Reminders work best graduated: a neutral first reminder, a firm second, then formal notice — each generated from exact balances, never from memory.

Used properly, the QR reference removes most manual debtor ticking. For e-invoicing, that means reminders triggered on reliable data and continuously readable cash flow — no more waiting for month-end to know who has paid.

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 Au (SG).

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

Au (SG): what changes, what does not

Working with a fiduciary from Au (SG) no longer depends on geography: the documents of a business in Au (SG) are shared online, while the canton St. Gallen keeps its own deadlines for the tax return.

Federal deadlines do not move in Au (SG): VAT within 60 days, salary declaration in January, 10-year record retention — postal code 9434 changes nothing about those rules, only the sender's address.

Frequently asked questions

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 Au (SG), 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 Au (SG) as anywhere.

Does MyFiducia.ai work for a business based in Au (SG)?

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 Au (SG) manages its documents, VAT and exports exactly as anywhere in Switzerland.

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 Au (SG): the CO dictates it, not the commune.
