Read transactions through recognition, double entry, and reconciliation
Financial accounting connects business events with supported records and financial statements. Start by identifying what occurred, which entity is involved, the relevant period, the evidence, and the accounting treatment under the applicable framework. A bank movement is not necessarily income or expense: receiving a loan creates financing, and paying a creditor can settle an existing liability. Likewise, a credit sale can create income and a receivable before cash arrives. Distinguish the event from its later settlement.
Use the accounting equation and double-entry logic. Assets are financed by liabilities and equity; each entry must preserve the relationship. Debits and credits are sides of an account, not universal synonyms for bad and good or money out and money in. The effect depends on the account type. A balanced trial balance shows a form of arithmetic agreement but does not prove that the right accounts, period, amounts, or transactions were used. An omitted or misclassified event can leave equal totals.
Accruals and valuations connect reporting to the period and facts. A prepaid service, an expense incurred but not yet invoiced, depreciation, inventory, and an uncertain receivable can each require analysis. State the method and assumptions used in a numerical exercise. A fictional useful life or allowance percentage should not be presented as a mandatory Swiss tax or accounting rate. Distinguish an estimate, a policy choice where permitted, and an error correction, and retain the evidence supporting each decision.
Reconcile supporting ledgers, bank information, inventories, and the general ledger. Investigate differences instead of forcing a balance with an unexplained entry. In Switzerland, the applicable obligations and reporting basis can involve the Code of Obligations and, where relevant, additional standards; German HGB or a foreign tax rule is not automatically the Swiss basis. These original exercises develop the subject's foundations and calculations without claiming to reproduce an official practical examination or establish every current statutory requirement. Use current Swiss sources and the actual entity's circumstances for real reporting.
