Artificial intelligence is fundamentally changing accounting. Not as a distant future trend, but as a concrete technology that Swiss SMEs and fiduciaries (Treuhänder) can use today. We show where AI brings the greatest time savings, which tasks it reliably takes over and where human judgement remains indispensable.
Contrary to the hype, AI in accounting is not a cure-all. It excels at clearly defined, repetitive tasks with structured data. That is exactly what makes it so valuable for day-to-day accounting work.
Reading in and classifying documents can largely be automated today. Modern AI models recognise invoice amounts, tax rates, payment terms and supplier data from a scan or PDF, particularly reliably for structured documents. Worked example, not a measurement: if manual entry takes 2 to 3 minutes per document, 200 documents per month involve around 7 to 10 hours of data entry work, a large part of which can be eliminated.
Once a system has seen enough of a company’s transactions, it learns the specific booking habits. Recurring suppliers are automatically assigned to the correct account. The bookkeeper confirms instead of entering. Typing errors in account assignment disappear.
AI systems can continuously check for anomalies: entries that deviate from the usual pattern, documents booked twice, missing invoices for recurring payments or unusual changes in amounts. This function is more valuable than it appears at first glance. It finds errors before the year-end closing comes and can point to possible attempts at fraud.
Value added tax is one of the most error-prone areas of accounting. During document processing, AI-supported systems can automatically extract the correct tax rate from the document and compare it with the account booked. If there are discrepancies, a warning is triggered. The VAT return is thus created from checked entries, which reduces the risk of errors.
No AI system makes business decisions. The question of whether an investment makes sense, whether a customer risk is acceptable or how a complex transaction should be structured in a tax-optimised way requires human judgement, industry knowledge and knowledge of the company’s individual situation.
AI relieves fiduciaries of routine work and gives them more time for precisely these advisory-intensive activities. Fiduciaries who use AI sensibly can handle more client mandates, provide higher-value advisory services and at the same time improve the quality of bookkeeping.
An important, often overlooked aspect: where does the AI model that processes your financial data run? Cloud-based AI services send your documents and booking data to external servers, depending on the provider in Switzerland, the EU or the USA. For many companies, this is acceptable. For accounting and fiduciary firms that manage client data, or for companies with increased data protection requirements, a local AI model is the better choice.
Local AI models run on your own hardware or in a data centre of your choice. The advantage: your documents are not sent to any cloud AI service for the AI analysis.
This is where AI-supported accounting can save time (an estimate, not a measurement; how much depends on the business):
Bilanzo integrates AI-supported document processing that runs on your local infrastructure: your documents are not sent to any cloud AI service for the AI analysis. The AI learns from your specific booking habits and becomes more precise with every document. Because Bilanzo works as an agent within your existing accounting software, you keep your usual solution and gain local AI automation on top, without changing systems. Start with 100 documents free of charge.

That depends on the volume of documents and varies from business to business. Worked example, not a measurement: at 2 to 3 minutes of manual entry per document, 200 documents per month involve around 7 to 10 hours of data entry work, a large part of which can be eliminated.
No. AI takes over repetitive routine work such as document capture, account assignment and plausibility checks. Business decisions, tax structuring and advice remain the task of the fiduciary.
