Everything that matters about e-invoicing for architecture firms in Eppenberg-Wöschnau

Whether you run a Sàrl, an SA or a sole proprietorship in Eppenberg-Wöschnau, 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

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.

For an SME in Eppenberg-Wöschnau, the real gain of digitalised e-invoicing shows day to day: no paper pile at month-end, VAT prepared continuously, and an owner reading today's figures rather than last quarter's.

The Swiss legal frame for e-invoicing

A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Eppenberg-Wöschnau as anywhere.

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?

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 clear mandate agreement states who does what by when: document handover, posting deadlines, filing calendar, and responsibility for delays. A shared platform (same data, same document archive) between the company and its fiduciary eliminates binder ping-pong and duplicate entry.

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 e-invoicing, invoicing fast changes everything: a service billed the week it is delivered gets paid noticeably earlier than a month-end batch invoice.

Eppenberg-Wöschnau: what changes, what does not

Eppenberg-Wöschnau (postal code 5012, canton Solothurn) applies the same federal rules as the rest of the country: what changes in Eppenberg-Wöschnau are the cantonal counterparts — tax administration, compensation office, commercial register.

Eppenberg-Wöschnau requires no special bookkeeping: the Code of Obligations applies at postal code 5012 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

Frequently asked questions

How much does e-invoicing cost in Eppenberg-Wöschnau?

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.

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 Eppenberg-Wöschnau can therefore archive fully digitally.

Can e-invoicing be automated with AI?

Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches e-invoicing.

What are the legal obligations for e-invoicing in Switzerland?

The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Eppenberg-Wöschnau: federal law applies.
