What ASC 606 Actually Means for SaaS Revenue (In Plain English) A founder closes a $120,000 annual contract in January, the cash lands in the bank, and the dashboard says the company just did $120K in revenue that month. It didn't. Under the accounting standard that governs this, the company earned $10,000. That gap — between the money you collected and the revenue you're allowed to report — is the whole reason ASC 606 SaaS revenue explained badly costs founders so much grief. They read their own P&L wrong, misjudge their growth rate, and walk into a due-diligence call with numbers that don't survive contact with an auditor. Here's what 606 actually says, without the FASB decoder ring. ASC 606 SaaS Revenue Explained: You Earn It When You Deliver, Not When They Pay ASC 606 is the revenue recognition standard the FASB issued to replace the old industry-by-industry rules. Its core principle is one sentence: you recognize revenue as you transfer the promised service to the customer, in the amount you expect to be entitled to. For a subscription business, that means a 12-month plan is delivered over 12 months. So you recognize one-twelfth of it each month. Sell that $120,000 annual contract and you book $10,000 in January, $10,000 in February, and so on through December. The cash showed up on day one. The revenue shows up across the year, because that's when you're actually doing the work the customer paid for. This is the single most common place revenue recognition SaaS founders trip. Bookings, billings, and recognized revenue are three different numbers, and 606 only lets one of them onto the income statement. Cash You Haven't Earned Yet Is a Liability So where does the other $110,000 sit in January? On the balance sheet, as deferred revenue — also called unearned revenue. And here's the part that surprises people: it's a liability, not an asset. That's not an accounting quirk. If you collected a year of cash and delivered one month, you still owe the customer eleven months of service. If you shut down in February, you'd owe most of that money back. A liability is exactly the right label. Each month, as you deliver, an equal slice moves off the deferred revenue line and onto the P&L as earned revenue. Deferred revenue shrinks, recognized revenue grows, and the cash never moved — it was always in the bank. For a deferred revenue startup that sells annual plans, this balance is often one of the largest items on the balance sheet. Lenders and investors read it as a signal of committed future revenue. Getting it wrong doesn't just misstate one month — it...
