RE:RE:RE:RE:RE:Q1
The goods that are shown as sales revenue for the period are reported for accounting purposes when ordered and delivered for that period. These sales if sold on account are reported as receivables and are collected based on credit terms set by the vendor. The reporting of sales revenue has nothing to do with the transfer of cash and so therefore the earnings or income derived from these sales are recorded in the same period when the sales are reported for accounting purposes. This is what they call the accrual basis of accounting which most businesses use. In your particular example the earnings or income would have been reported in the same period when the goods were sold and delivered and reported as revenue, which is period Q4. Hopefully this helps.
