Revenue
Definition
Revenue is the total income a business earns from its primary operations: selling products or services, before deducting any costs or expenses. Also called the "top line," revenue is the starting point for all profitability calculations and the most fundamental measure of business scale.
Overview
Revenue is the total amount earned from selling goods or services during a given period. For SaaS companies, revenue primarily comes from subscriptions, but can also include one-time setup fees, professional services, or usage-based charges. Each revenue stream should be tracked separately for accurate financial analysis.
Revenue follows specific recognition rules under accounting standards (ASC 606 / IFRS 15). A customer paying $12,000 upfront for an annual subscription generates $12,000 in cash but only $1,000 in recognized revenue per month. Understanding the difference between booked revenue, recognized revenue, and collected cash is essential for accurate reporting.
For startups, revenue growth rate is often more important than absolute revenue. Investors look for consistent month-over-month or year-over-year growth trends. However, revenue quality matters too, since recurring revenue from subscriptions is valued much more highly than one-time project revenue or services revenue.
Example
A SaaS company earns $30K/month from subscriptions and $5K from one-time consulting. Total monthly revenue is $35K, but only the $30K subscription portion counts toward MRR.
