Introduction

You've heard the term. Maybe your accountant mentioned it, or you've seen it on a tax form. Either way, if you run a business in Switzerland, understanding accrual accounting isn't optional — it could be legally required.

This guide explains what accrual accounting is, how it compares to cash accounting, and what Swiss law says about which method your business must follow. You'll also find practical examples, a clear comparison table, and guidance on when it's time to get professional support.

What Is Accrual Accounting?

Accrual accounting records income when it's earned and expenses when they're incurred — regardless of when cash actually moves.

Here's a simple example. Your company completes a project in November and sends an invoice. The client pays in January. Under accrual accounting, you record that income in November — because that's when you earned it, not when the payment landed.

The same logic applies to costs. If you receive a utility bill in April for services used in March, the expense goes in March.

This method ties revenue and costs to the period they actually belong to. That gives you a true picture of how your business is performing — not just how much cash is flowing through.

The Core Principle Behind It

Swiss accountants call this the Periodisierungsprinzip — the matching principle. It requires that every revenue and every cost appears in the accounting period when the underlying economic event occurred.

This isn't just good practice. It's embedded in Swiss accounting law and applies to the majority of businesses operating in Switzerland.

When Does Your Business Need Accrual Accounting?

Let's make this concrete.

You must use accrual accounting if:

You operate an AG or GmbH — no exceptions
Your sole proprietorship generates CHF 500,000 or more per year
You prepare financial statements under Swiss GAAP FER or IFRS
Your bank, investors, or lenders require GAAP-compliant accounts

You may use simplified (cash-based) accounting if:

You are a sole trader or general/limited partnership
Your annual revenue stays below CHF 500,000
No external stakeholders require audited or standard-compliant statements

Revenue Thresholds and Business Types

Even when cash-based accounting is permitted, many sole traders choose accrual accounting voluntarily. It supports better decision-making, simplifies VAT filings, and makes it easier to approach lenders or sell the business down the line.

If you're unsure which method applies to your situation — or if your revenue is approaching the CHF 500,000 threshold — speaking with a fiduciary in Vaud is the clearest path forward.

Pros and Cons of Accrual Accounting

No accounting method is perfect. Here's an honest look at both sides.

Advantages:

Gives a true and fair view of profitability for each reporting period
Matches revenues with the costs that generated them
Required by Swiss law for legal entities and larger sole traders
Makes year-end tax returns and financial statement preparation more straightforward
Strengthens your position with banks, auditors, and investors
Fully compliant with Swiss GAAP FER, IFRS, and the Swiss Code of Obligations

Disadvantages:

More complex than cash-based accounting
Requires more expertise — or professional support
Can show a paper profit even when cash flow is tight
Involves recurring year-end adjustments through transitory accounts

That last point matters. Your income statement may show strong profits, but if clients are slow to pay, your actual bank balance may tell a very different story. Understanding the gap between accrual profit and real cash flow is a skill every Swiss business owner should develop.

Cash vs. Accrual Accounting: The Real Difference

The difference between cash and accrual accounting comes down to timing.

Cash accounting: You record income when you receive payment and expenses when you pay them. Simple and intuitive — but it can paint a misleading picture.

Accrual accounting: You record income when it's earned and expenses when incurred. More involved — but far more accurate over time.

A Side-by-Side Comparison

Invoice sent in December, paid in January: Cash Accounting records it in January; Accrual Accounting records it in December.
Bill for February services received in March: Cash Accounting records it in March; Accrual Accounting records it in February.
Annual subscription paid upfront in January: Cash Accounting records - the full amount in January; Accrual Accounting spreads it across 12 months.
Salary earned in December, paid in January: Cash Accounting records it in January; Accrual Accounting records it in December.

With cash accounting, your December financials could look weaker than reality — and January would look artificially strong. Over a full year, totals may balance out. But within each reporting period, the picture can be skewed.

For businesses managing large invoices, seasonal cash flow, or multi-period contracts, the difference between these two methods can be substantial.

Swiss Accounting Rules: Cash Basis vs Accrual Basis

Switzerland doesn't leave this choice entirely open. The Swiss Code of Obligations (OR/CO) is clear about which method is required based on your business type and revenue.

Under Article 957 of the Swiss Code of Obligations, the rules are straightforward:

Full double-entry bookkeeping — accrual basis — is mandatory for:

All legal entities: AG, GmbH, cooperatives, associations, and foundations — regardless of size or revenue
Sole proprietors and general or limited partnerships with annual revenue of CHF 500,000 or more

Simplified cash-based accounting is permitted for:

Sole proprietors and partnerships with annual revenue below CHF 500,000

Simplified accounting tracks money in and money out, plus a basic record of assets and liabilities. It's easier to maintain, but it provides far less financial visibility.

Once your revenue crosses the CHF 500,000 mark, the law requires you to switch to full accrual-based double-entry bookkeeping. There's no gray area.

How to Switch from Cash to Accrual Accounting

If your business is growing toward the CHF 500,000 threshold — or if you've already passed it — here's what a transition looks like in practice.

Step 1: List all open invoices and unpaid bills: Identify every outstanding receivable and payable as of the transition date.
Step 2: Review prepaid and deferred items: Look for upfront payments in both directions that span more than one accounting period.
Step 3: Set up transitory accounts: Work with your accountant to create the right balance sheet accounts for accruals, deferrals, and provisions.
Step 4: Prepare your opening balance sheet: Your balance sheet at the start of the new period must reflect all accrual adjustments accurately.
Step 5: Update your bookkeeping workflow: Make sure your accounting software and internal processes can handle accrual entries on an ongoing basis.

This transition is manageable, but errors in the changeover year can affect your tax filing and key financial ratios. Working with a qualified fiduciary from the start prevents those issues from the ground up.

FAQ

Accrual accounting records income when it's earned and expenses when they're incurred, regardless of when cash moves. Cash accounting records transactions only when money is received or paid. Accrual accounting gives a more accurate picture of your business's financial performance within each reporting period, while cash accounting is simpler but can distort results — especially across period boundaries.
