Benchmark guidance

Retail and consumer companies typically operate on thin margins with high transaction volumes. Using PBT as a benchmark can result in materiality levels that are either unreasonably low (in lean years) or inappropriately high relative to the volume of transactions processed. Revenue provides a more stable base that better reflects the scale of operations.

Choosing the right benchmark

Revenue at 0.5–1% is the standard range for retail entities. The lower end is appropriate for large retailers where even small percentage misstatements represent significant absolute amounts. For smaller retailers with healthier margins, PBT at 5% remains a viable alternative.

Key audit considerations

Inventory shrinkage and valuation (particularly for perishable goods or fashion with markdown risk) may warrant lower specific materiality.

Revenue recognition for loyalty programmes, gift cards, and returns provisions can be complex under IFRS 15.

Lease accounting under IFRS 16 is significant for retailers with extensive store networks — right-of-use assets and lease liabilities can materially affect the balance sheet.

Seasonal fluctuations mean the timing of year-end relative to peak trading periods affects the audit approach and potentially the benchmark amount used.

How does ISA 320 define materiality?
ISA 320 requires auditors to determine materiality for the financial statements as a whole when establishing the overall audit strategy. The benchmark chosen and the percentage applied depend on the nature of the entity, the needs of financial statement users, and the auditor's professional judgment.
