As a self-employed person, freelancer or entrepreneur, you often want to do your bookkeeping yourself — in order to save costs and maintain full control of your business. But without deep accounting knowledge, mistakes quickly creep in, especially when the accounting software is complicated and confusing. These mistakes are often only noticed when the trustee checks the accounting — and that can be expensive.
The good news? modernism AI-powered accounting software automatically recognizes typical accounting errors and helps you avoid them right from the start. This not only saves you time, but also money. Here are the Seven most common accounting errors in Switzerland — and how you can prevent them with the right software.
1. Exchange rates
Companies that use foreign currencies face the challenge of correctly recording exchange rates in their accounting. A common mistake is that the actual exchange rate used (such as the rate used by the bank when payment is received) is different from official average of the Federal Tax Administration (FTA) deviates.
The FTA sets an average monthly exchange rate for various currencies, which is relevant for accounting. If the bank exchange rate is used instead of the FTA exchange rate in accounting, there may be differences that lead to incorrect tax calculations or discrepancies in financial accounting.
AI-based accounting software automatically recognizes whether the correct exchange rate has been applied and can calculate the difference between the effective bank rate and the ESTV rate. In this way, exchange rate differences are recorded correctly and accounting remains compliant with Swiss regulations.
2. Value-added tax calculation
The correct calculation of value added tax (VAT) is one of the most common sources of errors in accounting. Particularly problematic is the Reference tax, which many entrepreneurs overlook or misbook.
The purchase tax applies if you purchase services from a company based abroad — such as software subscriptions, consulting services, or online advertising (such as Google Ads, Facebook Ads). In these cases, the foreign provider issues the invoice without Swiss VAT off. Nevertheless, as a Swiss company, you are required to calculate the VAT on it and correctly record it in your accounting.
Common mistakes:
- The reference tax is not recorded, which leads to problems during a tax audit.
- Although VAT is calculated, it is not correctly claimed as input tax.
- The booking is made to the wrong account or is confused with normal VAT.
One AI-powered accounting software automatically recognizes invoices from abroad, notifies you that there is a purchase tax, and records it correctly. It ensures that the tax is recorded both as owed VAT and as deductible input tax — so that you are not at a financial disadvantage.
3. Rounding differences
Rounding differences often arise for invoices with multiple items, when different VAT rates are applied, or when payments are made in foreign currencies. Bank charges or currency conversions can also mean that the amount actually transferred differs slightly from the invoice amount recorded in accounting.
This can result in invoices being mistakenly shown as “pending” even though they have already been paid. Especially with large quantities of invoices, this quickly becomes confusing and causes additional work in manual post-processing.
AI-powered accounting software Makes it possible to Tolerance limit for different invoice amounts to define. This means: If a payment is within this specified range, the invoice is Recognized as paid despite minimal variance.
In addition, the software automatically recognizes rounding differences and posts them to the correct account. This keeps your bookkeeping clean and you no longer have to deal with unnecessary differences.
4. Manual booking
Manual postings are one of the most common sources of error in accounting. A wrong account, a number turner or a forgotten booking — and the financial figures are no longer correct. These mistakes are often difficult to correct and can lead to problems during tax audits.
In the past, manual data entry was unavoidable in accounting, but it is not only error-prone but also time-consuming. Anyone who has to post a lot of invoices and payments spends hours typing out receipts or comparing account statements with the accounting department.
