## Last-touch is a story about endings

Last-touch attribution gives 100% of the credit to whichever ad happened to be clicked closest to the conversion. In B2B SaaS, that's almost always a branded search ad. Branded search looks like a hero. Brand, podcast, content, and influencer spend look like waste.

The reality is that branded search is mostly capturing demand created upstream. Cut the brand and the branded-search numbers crash a month later.

## Assist conversions tell the truth

An assist conversion is any touchpoint in the buyer's journey that wasn't the last click but contributed to the deal. Multi-touch attribution gives partial credit to each assist, weighted by position or by a custom model.

The first time most B2B SaaS teams turn this on, they discover that 30-50% of pipeline is influenced by upper-funnel touches the last-touch report never showed.

## Defend the budget with one chart

Build a single chart that compares last-touch revenue to multi-touch influenced revenue, broken down by channel, for the last full quarter. Show it to your CFO. The conversation about brand spend gets easier, immediately.
