Accrual Accounting matches revenue to the period in which it is earned and expenses to the period in which they help generate that revenue. A Swiss SaaS that invoices a CHF 60,000 annual contract on 1 December books CHF 5,000 of revenue in December and CHF 55,000 as deferred revenue on the balance sheet, then releases CHF 5,000 each month over the following year.
Cash accounting (the alternative) records revenue and expenses when money moves. It's simpler but distorts every metric that matters: a fast-growing SaaS looks more profitable than it is when cash arrives upfront, and a struggling business looks healthier when receivables stretch. All European jurisdictions require accrual accounting for incorporated entities above small-company thresholds.
Accrual accounting drives the gap between MRR/ARR (the SaaS run-rate view) and statutory revenue (the recognised view). For a growing business they diverge sometimes by 2–3× — investors and lenders want both numbers, reconciled, in every board pack.
Recognised Revenue (period) = Σ (monthly portion of every active contract earned during the period) Deferred Revenue (balance sheet) = Total cash collected − Cumulative recognised revenue
Example: A Berlin SaaS signs a EUR 36,000 12-month contract on 1 June 2026. Customer pays EUR 36,000 upfront. June recognised revenue = EUR 3,000 (one month). June deferred revenue (balance sheet) = EUR 33,000. By June 2027, cumulative recognised revenue = EUR 36,000 and deferred revenue = EUR 0.
Accrual Accounting: The Complete Definition
Accrual accounting rests on the matching principle: revenue is recognised when control of the good or service passes to the customer (IFRS 15, ASC 606 in the US, broadly mirrored by Swiss CO art. 958c, German HGB §252, French PCG, Italian OIC 11). Cash timing is irrelevant — what matters is when the performance obligation is satisfied.
The mirror principle applies to expenses. Rent for January is a January expense even if paid in December (prepaid expenses on the balance sheet) or in February (accrued expenses on the balance sheet). Inventory becomes COGS in the period it is sold, not the period it was bought. This matching is what makes the P&L meaningfully reflect economic performance.
How Accrual Accounting Works: Formula and Example
The mechanics live in three balance-sheet accounts: deferred revenue (cash received but revenue not yet earned), accounts receivable (revenue earned but cash not yet collected), and accrued expenses (expense incurred but not yet paid). Each month-end, journal entries move amounts between these accounts and the P&L.
Worked example: a Lausanne SaaS invoices CHF 24,000 annually upfront on 15 March. March 15 journal entry: Dr Cash CHF 24,000, Cr Deferred Revenue CHF 24,000. March 31 entry (half-month recognition): Dr Deferred Revenue CHF 1,000, Cr Revenue CHF 1,000. Every subsequent month until next March: Dr Deferred Revenue CHF 2,000, Cr Revenue CHF 2,000.
Accrual Accounting in Switzerland, Germany, France and Italy
All four countries require accrual accounting for incorporated entities above small-company thresholds. Switzerland: CO art. 957 mandates accrual for entities above CHF 500K revenue; below that, sole proprietors can use cash. Germany: HGB §238 requires accrual for all Kaufleute (merchants); freelancers can use cash (Einnahmen-Überschuss-Rechnung) up to EUR 800K revenue.
France: micro-entrepreneurs below EUR 188,700 (services EUR 77,700) can use cash; above that, BNC/BIC require accrual. Italy: regime forfettario (up to EUR 85,000) uses cash; ordinary regime requires accrual. The audit thresholds (balance sheet, revenue, headcount) determine which detailed accounting standards apply — Swiss FER, German HGB+IFRS, French PCG, Italian OIC.
Why Accrual Accounting Matters
Accrual accounting is what makes financial statements comparable across companies and periods. Without it, a SaaS that gets all its cash upfront would look 5× more profitable than one billing monthly — same business, different cash timing, fundamentally different reported profit. Every valuation method (EBITDA multiples, DCF, P/E) implicitly assumes accrual numbers.
Operationally, accrual exposes problems that cash hides. Stretching accounts payable extends cash runway but doesn't change the P&L hit; growing receivables looks like sales success but ties up working capital. The MyEuroCalculator Cash Flow Forecast Calculator helps bridge the accrual P&L view to the cash reality.
Accrual vs Cash Accounting: Key Differences
Cash accounting is simpler but only honest for businesses where revenue and expenses happen close to cash timing (small services, retail). Accrual is harder but required for any business with inventory, deferred revenue, or material credit terms. The two can show wildly different profits for the same business in the same period.
Same SaaS, two accounting views (CHF, June 2026)
| Item | Cash view | Accrual view |
|---|---|---|
| Revenue | 120,000 (annual prepayments collected) | 10,000 (monthly recognition) |
| Salary expense | 40,000 (paid in June) | 40,000 (incurred in June) |
| Profit | 80,000 | −30,000 |
| Deferred revenue on BS | 0 | 110,000 |
Common mistakes
An annual prepayment must be deferred and released over 12 months. Recognising it all at signing is a misstatement and a common SaaS founder error.
Profitable businesses with stretching receivables can run out of cash; cash-rich businesses with deferred revenue can be deeply unprofitable. Read all three statements.
Salaries for the last week of December are a December expense even if paid in early January. Missing this overstates Q4 profit.
MRR is a non-GAAP run-rate metric; statutory revenue is the accrual-based amount actually earned. For growing SaaS they diverge — keep both numbers visible.
