Fruitless & Wasteful

Fruitless Expenditure — Late-Payment Interest

Interest and penalties paid because suppliers and statutory bodies were settled late.

📖 6 min read🎯 Intermediate✍️ Updated 2026

Why late-payment interest is wasteful

Interest and penalties paid because creditors or statutory bodies were settled late is the textbook definition of fruitless and wasteful expenditure: money that could have been avoided with reasonable care. The MFMA and PFMA, together with Treasury's 30-day payment rule, make prompt settlement a legal duty, and SARS, pension funds and bulk suppliers charge punitively for delay. AuditPro Core reconciles payment dates against due dates and isolates the avoidable interest component, giving the accounting officer a direct, quantified measure of cash lost to administrative drift.

Avoidability test

Expenditure is fruitless and wasteful when it was made in vain and could have been avoided had reasonable care been exercised. Interest on a late payment meets that test almost by definition because timely payment was within the entity's control.

The 30-day rule

Treasury requires valid invoices to be paid within 30 days, and breaching it both causes interest and constitutes a compliance finding. Persistent late payment also signals cash-flow or workflow failures upstream.

Statutory creditors

Late settlement of SARS, pension and bargaining-council obligations attracts the steepest penalties and can expose officials personally. These should be the first creditors a wasteful-expenditure review isolates.

How AuditPro Core Bridges the Gap

  • Due-date reconciliation: payment dates are matched to invoice due dates so overdue settlements are identified automatically.
  • Interest isolation: the avoidable interest and penalty component is separated from principal to quantify the true wasteful amount.
  • 30-day exception workflow: invoices approaching breach raise an exception so payment can be expedited before interest accrues.
  • Traceability to source: each interest charge links to the originating invoice and payment record for the wasteful-expenditure register.

Key Takeaways

  • Late-payment interest is almost always avoidable and therefore fruitless and wasteful by definition.
  • Breaching the 30-day rule causes both interest and a separate compliance finding.
  • Statutory creditors carry the harshest penalties and warrant priority monitoring.
  • Quantify the interest component separately so the wasteful amount is defensible.
