QR-bill invoicing for construction companies in Wohlen (AG) explained simply

QR-bill invoicing for construction companies in Wohlen (AG) rests on three pillars: federal law that applies across Switzerland, cantonal deadlines worth knowing, and tools that eliminate re-keying. This guide puts it all in order, fact by fact.

Digitalising QR-bill invoicing: what actually works

Automation is judged on the exceptions: what happens when the document is unreadable, the supplier unknown, the amount divergent? A good tool isolates those cases and lets a human decide fast — precious for teams in Wohlen (AG).

For QR-bill 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

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.

A business in Wohlen (AG) 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 QR-bill invoicing

AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Wohlen (AG) with a clean audit trail sails through these exercises.

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

Professional in a suit reviewing documents

Outsource QR-bill 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.

Three signals say it is time to delegate more: missed deadlines (VAT, AHV), entries running months behind, or an owner spending evenings on receipts instead of the business. Conversely, an SME equipped with modern software can safely take day-to-day entry back in-house.

Wohlen (AG): what changes, what does not

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

Federal deadlines do not move in Wohlen (AG): VAT within 60 days, salary declaration in January, 10-year record retention — postal code 5610 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 Wohlen (AG): the CO dictates it, not the commune.

When must a business register for VAT?

As soon as its worldwide annual turnover reaches CHF 100,000 (CHF 250,000 for non-profit sports or cultural associations). Below that, voluntary registration remains possible and often makes sense to reclaim input VAT on investments. The threshold is federal: it applies in Wohlen (AG) as everywhere in Switzerland.

How long must records related to QR-bill 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 Wohlen (AG) can therefore archive fully digitally.

What are the legal obligations for QR-bill 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 Wohlen (AG): federal law applies.
