Deferred Revenue

When a customer pays upfront for a service to be delivered over time, the company cannot recognize that payment as revenue immediately. Instead, it records the cash received as a current liability (deferred revenue). As the company delivers the service, it 'earns' the revenue, moving it from the balance sheet to the income statement. For example, a SaaS company receiving a $120K annual subscription records $120K in deferred revenue on Day 1 and recognizes $10K of revenue each month.

Deferred revenue is a source of cash when it increases (cash was received but revenue not yet recognized) and a use of cash when it decreases (revenue was recognized from prior cash collections). On the cash flow statement, an increase in deferred revenue is added back in the operating section, boosting CFO. This is why subscription businesses with growing deferred revenue balances often have CFO exceeding net income — they are collecting cash before they earn it.

In tech acquisitions, deferred revenue gets a 'haircut' under purchase accounting. The acquirer re-measures deferred revenue at fair value (the cost to fulfill the obligation, not the amount collected), which is typically much lower than the book value. This reduces recognized revenue post-close, creating a disconnect that analysts must adjust for when evaluating the combined entity's growth. Buyers often specify deferred revenue adjustments in deal terms.

These are opposite concepts. Accounts receivable = revenue recognized but cash not yet collected (asset). Deferred revenue = cash collected but revenue not yet recognized (liability). Both are resolved over time: AR converts to cash, deferred revenue converts to revenue. A company can have both simultaneously — for example, a SaaS company may have AR from enterprise customers invoiced net-30 and deferred revenue from customers who pre-paid annually.
