What is ROAS?
ROAS (Return on Ad Spend) measures how much revenue you generate for every dollar spent on advertising. It's the most direct metric for evaluating advertising profitability.
ROAS = Revenue from Ads / Ad Spend
A ROAS of 5:1 means you generated $5 in revenue for every $1 spent on ads. A ROAS below 1:1 means you're losing money.
Why ROAS Matters for B2B Sales
In B2B, ROAS is essential for justifying continued ad spend to leadership. However, B2B ROAS can be tricky to measure because sales cycles are long (30-180 days), multiple touchpoints influence deals, and attribution is complex. A click today might not become revenue for 6 months.
This long attribution window means B2B teams need patience and proper tracking infrastructure to accurately measure ROAS.
Key Benchmarks
- Breakeven ROAS: 1:1 (revenue equals ad spend)
- Good B2B ROAS: 3:1 to 5:1 (accounting for long sales cycles)
- Excellent ROAS: 5:1+ (rare in B2B, more common in e-commerce)
- Target varies by margin: High-margin products can sustain lower ROAS
ROAS vs ROI
- ROAS: Only measures ad spend against revenue, doesn't include other costs
- ROI: Accounts for all costs (salaries, tools, overhead), gives a more complete picture
- In practice: ROAS is used for campaign-level optimization; ROI for business-level decisions
Common Mistakes
- Short attribution windows: B2B sales cycles mean a 30-day ROAS window misses most revenue
- Ignoring pipeline value: Count influenced pipeline, not just closed revenue
- Not factoring LTV: First-purchase ROAS might look low, but LTV makes it profitable
- Channel-level blinders: ROAS for one channel may improve other channels (e.g., brand ads improving outbound)
How FlowStrata Evaluates ROAS
FlowStrata helps clients evaluate the true ROAS of their marketing channels by comparing paid acquisition costs against outbound costs. We often demonstrate that outbound lead generation achieves superior effective ROAS compared to paid channels, especially when factoring in the higher qualification rates and shorter sales cycles that targeted outbound typically delivers. Our reporting tracks pipeline and revenue attribution across all channels for accurate cross-channel ROAS analysis.
