Tips for Organising the Accounting of Your Sole Proprietorship

Accounting is the backbone of every successful sole proprietorship. Well-organised financial management not only saves time and nerves, but also enables you to make informed business decisions. Yet many self-employed individuals keep putting off their accounting — and find themselves facing a mountain of unprocessed receipts and missing figures at the end of the year. It does not have to be this way. With the right strategies, accounting becomes efficient and straightforward. Here are proven tips to help you stay organised from the start:

1. Use digital accounting tools

Modern accounting software such as Effizo makes it easier to record and manage your finances. It offers features such as:

• Automatic capture of receipts
• Clear reports on business performance via the dashboard
• Support with VAT accounting

By using digital tools, you minimise errors and save valuable time. Especially for sole proprietorships in Switzerland that do not need to maintain double-entry bookkeeping, a lean tool is often the better choice compared to an overloaded program with unnecessary features.

2. Schedule regular accounting maintenance

Plan fixed time slots for your accounting — whether weekly or monthly. Regular updates prevent tasks from piling up and protect you from unnecessary stress at the end of the year.

A proven rhythm for sole proprietorships:

• Weekly: Capture and upload receipts (approx. 10-15 minutes)
• Monthly: Review income and expenses, check outstanding items (approx. 30 minutes)
• Quarterly: Prepare VAT returns (if VAT-registered)
• Annually: Prepare year-end closing and compile documents for the tax return

Those who maintain their accounting regularly spend significantly less total time on it than someone who postpones everything until the end of the year.

3. Digitise receipts

Paper receipts are easily lost, fade over time, and are difficult to search. Scan receipts and invoices promptly and store them securely in a digital folder or directly in your accounting software. This not only simplifies tax returns, but also ensures clear and organised documentation.

Keep the following in mind:

• Digitise immediately: Photograph or scan receipts on the same day if possible — so nothing gets lost.
• Consistent naming: Name files according to a consistent scheme, e.g. with date and supplier (2026-01-15_Swisscom.pdf).
• Retention obligation: In Switzerland, business documents must be retained for at least 10 years. Digital receipts are legally recognised for this purpose, provided they are complete and unaltered.

4. Separate private and business finances

A separate business account is essential. It ensures a clear distinction between private and business transactions, simplifies bookkeeping, and meets the requirements of the tax authorities.

This applies not only to bank accounts — you should also consistently separate credit cards, PayPal, and other payment methods. If you use an expense partly for private and partly for business purposes (e.g. a mobile phone subscription), document the business portion clearly and traceably.

5. Define categories and structure

Define clear categories for your income and expenses from the outset. Typical categories for sole proprietorships include:

• Materials and goods purchases
• Office and workspace
• Phone and internet
• Software and licences
• Insurance
• Vehicle and travel
• Marketing and advertising
• Continuing education

Consistent categorisation not only makes it easier to keep an overview but also simplifies tax returns — because you can immediately see which expenses are deductible. Make sure you choose categories that fit your business model, and stick consistently to the structure you have chosen. Reclassifying later wastes unnecessary time.

6. Consider support from a tax advisor

If accounting seems too complex or you want to focus on your core business, working with a tax advisor can be worthwhile. An expert helps you take advantage of tax benefits and avoid mistakes. The costs for a tax advisor are, by the way, fully deductible as a business expense.

With well-maintained digital accounting, you can also give your tax advisor direct access to your data — saving time and costs in the collaboration. Effizo offers a user management feature with an unlimited number of users for this purpose.

7. Prepare early for your tax return

Collect all relevant documents — such as bank statements, receipts, and annual reports — in good time. Structured accounting not only saves time, but also reduces stress around tax filing.

Checklist for your tax return:

• Compilation of all income and expenses
• Receipts for deductible costs (home office, vehicle, continuing education)
• VAT returns (if VAT-registered)
• Business bank account statements
• Inventory and asset register (if applicable)

8. Keep VAT on your radar early

If your turnover exceeds the threshold of CHF 100,000 per year, you become VAT-liable. Prepare for this by documenting your income cleanly from the start and considering the VAT rates on your invoices. This ensures a smooth transition if the time comes.
