Accounting software for tradespeople in Erlinsbach (AG): what every SME should know
Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on accounting software in Erlinsbach (AG): what the law requires, what can be automated, and when to delegate.
Digitalising accounting software: what actually works
Digitising does not mean hoarding PDFs: without the document-entry link, a digital file is as opaque as a box of archives — true in Erlinsbach (AG) as everywhere.
Migrate in stages: supplier invoices first (high volume, immediate gain), then receivables with the QR-bill, finally payroll and the closing. At each stage, comparing one month before/after is enough to prove the gain — no theoretical promises needed.
Outsource accounting software or keep it in-house?
A good test before choosing: ask the fiduciary HOW it wants to receive the documents. A precise answer (formats, frequency, platform) says more than any brochure — including in Erlinsbach (AG).
For accounting software, a quarterly 30-minute check-in with the fiduciary beats an annual marathon: questions get handled while they are small.
The Swiss legal frame for accounting software
Whether a business sits in Erlinsbach (AG) or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for accounting software. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
One simple principle drives accounting software: every franc in or out must be explainable by a document, an entry and an account. All of Swiss accounting law fits inside that traceability requirement.

A well-structured SME chart of accounts
A good chart of accounts tells the story of the business: classes 1 and 2 describe what it owns and owes, class 3 what it sells, classes 4 to 6 what it consumes. Private accounts (sole proprietorships) and shareholder current accounts (Sàrl/SA) must stay spotless: they are the first thing examined in a tax audit.
For a business in Erlinsbach (AG), the Sterchi/Käfer structure also eases benchmarking: banks and fiduciaries reason on those standard classes to situate an SME's accounting software.
Erlinsbach (AG): what changes, what does not
Working with a fiduciary from Erlinsbach (AG) no longer depends on geography: the documents of a business in Erlinsbach (AG) are shared online, while the canton Aargau keeps its own deadlines for the tax return.
Erlinsbach (AG) requires no special bookkeeping: the Code of Obligations applies at postal code 5017 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
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 Erlinsbach (AG) as anywhere.
What are the legal obligations for accounting software 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 Erlinsbach (AG): federal law applies.
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 Erlinsbach (AG) as everywhere in Switzerland.
How long must records related to accounting software 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 Erlinsbach (AG) can therefore archive fully digitally.
