operating cash flow

Also called: cash from operations

Cash generated or used by the core business in a period: profit adjusted for non-cash items and for changes in working capital.

Operating cash flow is the cash the core business generated or used in a period: customers' payments minus what it paid providers, staff and suppliers, leaving out equipment purchases (investing) and loans or owners' money (financing).

It is usually derived from profit: operating cash flow = profit + non-cash costs (depreciation and amortization) − increase in receivables − increase in prepaid expenses + increase in payables + increase in deferred revenue. Each adjustment is a timing difference between when the P&L counts something and when money moves. Depending on the accounting standard, interest and taxes paid may sit in this section too.

The gap between operating cash flow and profit tells you how the business is financed day to day. A prepaid business that is growing shows operating cash flow well above profit: customers pay before they are served. When its sales slow, the same mechanism runs backwards. A business on payment terms shows the opposite. Operating cash flow that is boosted by paying suppliers later is weaker than it looks: that effect can be used once.

Example

Klasna in two stretches of the same school year, in UAH:

	Sep 2025 – May 2026	Full year to 31 Aug 2026
Operating profit	1,647,290.72	744,174.72
Change in prepaid lessons	+1,578,469	−1,086,661
Provider's fees on that change	−39,461.72	+27,166.53
Operating cash flow	3,186,298	−315,319.75

Nine months: 1,647,290.72 + 1,578,469 − 39,461.72 = 3,186,298, nearly twice the profit, because families prepaid lessons faster than they used them. Then the summer: operations lose 1,647,290.72 − 744,174.72 = 903,116 and families use the lessons they had prepaid. For the whole year the operating cash flow is negative while profit is positive.

Common mistakes

Comparing it with profit for a single month or season. Timing differences swing it; look at a full cycle.
Celebrating cash from prepayments as earnings. It's service still owed; it comes back out when customers use it.
Boosting it by paying suppliers late. The gain happens once and costs trust.
Leaving capex out of the picture. Operating cash flow minus capex is what the business really has left.
