The 4 numbers

COGS: The direct cost of delivering your product: cloud, third-party services in the product, support and SRE.
OPEX: Everything below gross profit: R&D (most engineering), sales & marketing, and G&A.
Revenue: What you earned from customers in the period (recognized revenue), not what you billed or collected.
Earnings: Net income. What's left after every cost, interest and tax. It's not cash.
