Under the indirect method in ASC 230, net income includes expenses as they are incurred, whether or not the supplier has been paid. The change in payables corrects for that timing. In XBRL, companies tag the line IncreaseDecreaseInAccountsPayable, which covers amounts owed to vendors for goods and services, usually after an invoice has been received. Companies that combine payables with accrued expenses use IncreaseDecreaseInAccountsPayableAndAccruedLiabilities instead, so the two are not always comparable across filers.
As with other working capital lines, the figure may not match the balance sheet difference. Payables assumed in an acquisition, currency translation, and payables for capital equipment (which relate to investing, not operating, activity) can all move the balance without flowing through this line. Supplier finance programs, in which a bank pays the supplier early and the company pays the bank later, can stretch payables and lift operating cash flow. ASU 2022-04 requires companies to disclose the key terms and outstanding amounts of such programs, which helps readers spot the effect.
Analysts read this line together with days payable outstanding. Stretching suppliers is a legitimate source of cash, and large retailers routinely fund inventory this way. But a one-time surge in payables can inflate operating cash flow for a single period and then reverse, so a jump in cash flow driven mainly by this line deserves a closer look.
