Everything that matters about e-invoicing for engineering firms in Anwil

E-invoicing for engineering firms in Anwil 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

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.

For e-invoicing, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.

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 Anwil.

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.

A well-structured SME chart of accounts

Nearly all Swiss SMEs rely on the standard SME chart of accounts (Sterchi/Käfer): classes 1 (assets) to 9 (closing), with revenue in class 3 and expenses in classes 4 to 6. Using this standard structure makes conversations with your fiduciary, auditor and tax administration far easier.

For a business in Anwil, the Sterchi/Käfer structure also eases benchmarking: banks and fiduciaries reason on those standard classes to situate an SME's e-invoicing.

QR-bills and friction-free collections

Technically, two routes coexist: the classic IBAN with an optional reference, or the QR-IBAN which requires a structured 27-position QR reference. Only the second route makes matching truly automatic — every payment carries the exact identifier of its invoice.

For an SME in Anwil, receivables are an asset to manage: a weekly ageing balance, graduated reminders and a provision for doubtful cases — e-invoicing provides the numbers, discipline does the rest.

Anwil: what changes, what does not

Sole proprietorship, Sàrl or SA in Anwil: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Basel-Country.

Federal deadlines do not move in Anwil: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4469 changes nothing about those rules, only the sender's address.

Frequently asked questions

How much does e-invoicing cost in Anwil?

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.

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 Anwil.

What are the current Swiss VAT rates?

Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Anwil.

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 Anwil: the CO dictates it, not the commune.
