Profit Today, Cash Later

Begin with three categories. Inventory is goods held within the model; receivables are amounts customers owe for its credit sales; payables are amounts it owes suppliers for its credit purchases. These balances describe positions at a point or an average across a period. Sales and purchase flows describe activity over that period.

A balance of receivables 9,000 is not a statement that 9,000 arrived in cash today. Similarly, an inventory balance does not say when its goods will sell, or whether they can all be sold at their stated value. A payable amount does not create permission to postpone a contracted payment. Timing measures need the relevant flow and explicit assumptions.

Use one comparable period and currency throughout an exercise. Here the period has 360 days by stipulation, not because every financial year uses that convention. All amounts are invented. Average inventory is 12,000, average trade receivables 9,000 and average trade payables 6,000. We also supply cost of sales 144,000, credit sales 216,000 and credit purchases 144,000 for that same period.

Keep the bases visible. Cost of sales and purchases happen to be equal in this fictional dataset; that is not a universal accounting identity. The distinction becomes important when inventory changes or other adjustments exist. Identify whether balances are genuine period averages or merely closing snapshots before interpreting a ratio. You cannot reconstruct a reliable payment calendar from three totals alone, and no personal customer or supplier records are needed for this practice.
