You're sitting at your laptop, the QR invoices are sent, two receipts are still on your phone, and the same question runs through your head as many solo self-employed people in Switzerland ask: What do I really need to book today, and when does it officially become more than just a simple invoice list? That's exactly where sole proprietorship accounting comes in. If you run your Einzelfirma cleanly, you don't have to wait until the annual financial statement is at the door — you organize your processes so that turnover thresholds, receipt management and MWST fit together in everyday life.

For many, this feels vague at first because invoicing, receipts, bank reconciliation and tax questions often end up in separate drawers. In practice, they belong together, especially in Switzerland, where three thresholds set the pace: CHF 500,000 annual turnover for the accounting method, CHF 100,000 annual turnover for MWST and a retention period of up to 10 years for many business documents Nexova on accounting solutions for Swiss SMEs, Für Gründer on accounting and retention. Once you think these thresholds through together, you can much more quickly tell whether a simple receipt is sufficient, whether MWST is running correctly, or whether double-entry accounting is already required.

In practical terms, this also means that digital organization is not a luxury. Anyone who files receipts immediately and assigns payments directly saves themselves tedious searching later, as guides on digital accounting also emphasize, such as the digitization of accounting according to GoBD from other providers. If you use a lean, digital solution from the start, you have your accounting under control — without a bureaucracy shock at year-end.
