How is B2B ROAS different from eCommerce ROAS?

In eCommerce, a conversion is a sale, so revenue is immediate and ROAS is straightforward. In B2B, a conversion is usually a lead that may close weeks or months later, so immediate-revenue ROAS dramatically understates performance. A B2B ROAS calculation has to step through the journey: clicks → leads → customers (via your lead-to-customer rate) → revenue (via average deal value). This calculator boots on the B2B tab so those steps are built in.

What lead-to-customer rate should I use?

Use your own historical close rate from marketing-qualified lead to closed-won deal if you have it — it varies enormously by motion (often 1–5% for top-of-funnel inbound, much higher for high-intent demo requests). If you do not have a reliable number yet, model a conservative range and watch how sensitive your ROAS is to it; in long B2B cycles the lead-to-customer rate is usually the single biggest driver of true ROAS.

Why does B2B tolerate a lower ROAS than eCommerce?

Because B2B customer lifetime value is typically much larger and more durable: a single closed account can pay back acquisition cost many times over across a multi-year contract. B2B teams therefore often accept a lower first-order ROAS, judging paid media on pipeline and LTV-adjusted return rather than immediate revenue. Pair this with an LTV calculation to see the full picture.

Return on Ad Spend

Return on Ad Spend (ROAS) is a marketing performance metric that measures the revenue generated per dollar of advertising spend. Unlike ROI which considers all business costs, ROAS specifically evaluates advertising efficiency by comparing directly attributable revenue to ad spend. This metric is crucial for optimizing campaign performance, budget allocation, and overall marketing strategy.

Customer Journey

The customer journey maps the comprehensive progression of interactions between a customer and brand across all channels, devices, and time periods. In modern digital marketing, it represents a non-linear, dynamic path encompassing both active and passive touchpoints - from initial brand discovery through consideration, purchase, and ongoing loyalty. This journey requires sophisticated cross-channel tracking, multi-touch attribution modeling, and strategic message orchestration to effectively guide users toward desired outcomes while delivering value at each stage.
