Changes in receivables is a line item on the Statement of Cash Flow that identifies the increase or decrease in a company's receivables from the previous reporting period to the current reporting period.

Changes in Receivables = Receivables for Current Reporting Period - Inventory from Previous Reporting Period

Let's say Company A had $1,000 in receivables at the end of last quarter and has $2,000 in receivables at the end of the current quarter. As a result, the changes in receivables for the current quarter are $1,000 (2,000 - 1,000).
