Assume unless I say otherwise that I am always supposing a y/e of 31 December.
An invoice dated 3 January – $1,000 – shows a receipt of goods in December. A credit note date 7 January – $1,000 – shows that the same goods were returned to the supplier because the goods were faulty.
Conclusion – no accrual needed for the invoice – but the auditor will need to check that the goods are not included in y/e inventory valuation.
