ASC 606
The US GAAP standard governing revenue recognition from contracts with customers, in force since 2018.

ASC 606 (and its IFRS twin, IFRS 15) enforces a five-step model: identify the contract, identify performance obligations, determine transaction price, allocate to obligations, recognise as satisfied. It's why sales, product and finance argue about what counts as 'one product' vs. 'a bundle'.
