Accrual accounting exposes the lie: profit isn't about when money hits the bank — it's about when you've earned or consumed something. Balance day adjustments force the books to tell the truth at period end. Drag the timeline to see how the same transaction splits across periods.
Prepaid expenses are when you pay cash now but consume the benefit later — like insurance or rent paid in advance. At balance day, the unused portion sits on the balance sheet as an asset (prepaid expense), not on the income statement. Without the adjustment, Period 1 profit is understated because you've expensed something you haven't yet consumed. The adjustment shifts the expense forward into the period where it's actually used, matching cost to benefit. This is accrual accounting's core promise: economic reality wins over cash movement.
Accrual accounting matches revenue and expenses to the period they belong to — adjustments at balance day fix timing mismatches so profit reflects economic truth, not just when cash moved.
