Plain definition
Cash accounting records income when money is received and expenses when money is paid. It gives a direct view of bank movement and may suit simple monitoring or contexts that permit it. It does not, by itself, show unpaid supplier obligations, revenue already earned but not collected, or goods and services consumed before payment. For general-purpose IFRS financial statements, it is not the accrual basis required for reporting performance and financial position.
The useful distinction is cash management versus period performance. A bank balance tells management whether payments can be made; it does not necessarily show which month created the revenue or used the resource.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
A catering company receives from a customer on 3 January for an event it delivered on 28 December. It also pays to a food supplier on 8 January for ingredients received in December. Cash accounting reports both movements in January: received and paid. Under accrual accounting, the December accounts recognise the December revenue and ingredient cost, even though the cash arrives and leaves later.
Cash accounting is not useless; the January movements belong in the cash forecast. The limitation is using those movements alone to judge December's margin.
Why it matters
If the owner looks only at January cash receipts and payments, January can appear unusually active while December looks too quiet. That may lead to poor pricing, staffing, or spending decisions because the comparison mixes operational activity with collection and payment terms.
Practical consequence
Maintain a dated cash forecast from expected bank movements, including tax and payroll dates. Separately, use the reporting basis required for management accounts and statutory financial statements. Reconcile the forecast to bank activity weekly, and at each close identify material unpaid bills, uncollected delivered sales, and advance payments so that cash timing does not silently become the performance measure.
