Everything that matters about e-invoicing required documents in Erschwil
Swiss accounting law (art. 957 ff. of the Code of Obligations) sets a precise frame, yet day-to-day practice often stays fuzzy. This guide walks through what actually matters for a business based in Erschwil.
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.
QR-bills and friction-free collections
Clear payment terms, a visible due date, exact details: half of late payments come from ambiguous invoices, not bad payers — the finding holds in Erschwil too.
A business in Erschwil can collect by QR-bill even without sophisticated software: what matters is that every incoming payment finds its invoice, manually or automatically.
The Swiss legal frame for e-invoicing
Whether a business sits in Erschwil or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for e-invoicing. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
Late books show from the outside: poorly calibrated tax instalments, provisional filings, slow answers to the bank. Staying current is also a matter of image.

Outsource e-invoicing or keep it in-house?
Outsourcing e-invoicing 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.
A business in Erschwil can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — e-invoicing splits very well.
Erschwil: what changes, what does not
Working with a fiduciary from Erschwil no longer depends on geography: the documents of a business in Erschwil are shared online, while the canton Solothurn keeps its own deadlines for the tax return.
Federal deadlines do not move in Erschwil: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4228 changes nothing about those rules, only the sender's address.
Frequently asked questions
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 Erschwil as anywhere.
How long must records related to e-invoicing be kept?
Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Erschwil can therefore archive fully digitally.
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 Erschwil.
