Revenue attribution

Definition

Revenue attrition refers to the loss of recurring revenue over a given period due to customer churn, downgrades, or canceled contracts. It’s the inverse of revenue retention and a key metric for understanding how much revenue your business is losing - either from customers leaving or spending less.

Why revenue attribution matters now

It is no secret that in complex B2B sales, deals rarely come from a single source. A buyer might discover you through a podcast, attend a webinar, talk to a rep, read a case study, and only then raise their hand. Revenue attribution is the process of determining which touchpoints contributed to the deal and which ones actually moved it forward.

Without a working attribution model, your go-to-market (GTM) decisions are based on gut feel, not data.

What attribution tries to answer

  • Which channels create pipeline that converts?
  • What role does content (case studies, blogs, product updates) play in closing deals?
  • Are outbound efforts driving revenue or just meetings?
  • How should we allocate budget across marketing, sales, and enablement?

Common attribution models

Model What it does Limitation
First-touch Credits the first interaction Undervalues mid-funnel and close
Last-touch Credits the last known touchpoint before deal Ignores early education
Linear Divides credit equally across all touches Assumes all touches matter equally
U-shaped Weighs first and last more heavily Still limited for multi-threaded deals
W-shaped Credits first, lead conversion, and close Better, but not fully account-based
Custom or ML-based Uses AI to weight based on impact Requires strong data and modeling

There’s no perfect model, but bad attribution can lead to misallocated spend and missed opportunities.

Challenges in real-world attribution

  • Data lives in silos across CRM, marketing automation, and CS tools
  • Self-reported attribution is incomplete or biased
  • Offline touchpoints (e.g., founder-led deals, events, referrals) are hard to track
  • Multi-threaded buying committees muddy the picture
  • Sales input is rarely factored into attribution models

How mature teams approach it

  • Use hybrid attribution (data + rep input) to capture nuance
  • Measure revenue influence across entire deal lifecycle and not just lead gen
  • Align attribution reporting to how real buyers move (e.g. long consideration cycles)
  • Use attribution insights to shape content strategy, rep enablement, and budget allocation

The more cross-functional your sales cycle, the more critical attribution becomes.
