QR-bill invoicing for plumbers in Oeschgen: what every SME should know
QR-bill invoicing for plumbers in Oeschgen 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
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.
The selection criterion for a tool is not the length of its feature list but the robustness of the daily flow: reliable bank imports, VAT computed correctly (8.1 / 2.6 / 3.8%), a complete audit trail from document to entry, and a clean export for the auditor or fiduciary. Everything else is secondary.
The Swiss legal frame for QR-bill invoicing
For an owner in Oeschgen, the question is never “do we need accounts?” but “at what level of detail?”. The CO sets the floor; the bank, the tax office and the shareholders set the rest.
The annual accounts (art. 958 CO) consist of the balance sheet, the income statement and the notes; they must be drawn up within six months of the year-end so the general meeting can approve them. A delay here cascades into the tax return and the final social insurance settlements.
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.
Changing fiduciary is not a drama: the accounting data belongs to the company, and a clean export (entries, chart of accounts, linked documents) allows a transition at year-end. A provider who locks in a client's data says a lot about how it works.

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.
For QR-bill invoicing, the share of collections matched automatically is a metric worth watching: when it drops, it is almost always a matter of misused references.
Oeschgen: what changes, what does not
Oeschgen (postal code 5072, canton Aargau) applies the same federal rules as the rest of the country: what changes in Oeschgen are the cantonal counterparts — tax administration, compensation office, commercial register.
Federal deadlines do not move in Oeschgen: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 5072 changes nothing about those rules, only the sender's address.
Frequently asked questions
How much does QR-bill invoicing cost in Oeschgen?
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.
Do you need a fiduciary for QR-bill invoicing, or can you do it yourself?
Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Oeschgen.
Does MyFiducia.ai work for a business based in Oeschgen?
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 Oeschgen manages its documents, VAT and exports exactly as anywhere in Switzerland.
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 Oeschgen as anywhere.
