B2B Attribution That Survives a Long Sales Cycle
In B2B the conversion and the revenue are separated by months and a committee, which breaks every out-of-the-box attribution report. Last click credits the demo form and forgets the six months of touches before it. The ad platforms optimise on form fills because nobody feeds them anything better. The fix lives in the CRM: capture source durably at entry, stamp it through every stage, and send the outcomes back to the systems doing the spending.
What changes at this scale
The CRM is the attribution system
Analytics tools forget visitors in months; your sales cycle is longer than their memory. Source, medium, campaign and click IDs get written onto the CRM record at creation and never overwritten, so the deal that closes in March still knows about the click from June.
First touch and last touch are both kept
One tells you what creates demand, the other what harvests it, and single-model reporting always starves one to feed the other. We report both, plus stage progression by source, and resist the urge to pretend fractional credit is science.
Offline conversions close the loop
Qualified opportunities and closed-won deals flow back into Google Ads and LinkedIn with values attached. The platforms stop optimising toward whoever fills forms fastest and start optimising toward whoever becomes pipeline.
Definitions are agreed before dashboards exist
What counts as an MQL, an opportunity, a win, and who owns each definition, gets written down with sales in the room. Every attribution project that skips this ships a dashboard nobody trusts by the second quarter.
Everything you get

- Hidden field and form plumbing that survives your form stack
- Offline conversion import to Google Ads and LinkedIn with values
- Stage progression reporting by source and campaign
- First and last touch reported side by side
- Self-reported attribution field, reconciled against the tracked data
- Definitions document agreed between marketing and sales
- A pipeline dashboard that reconciles with the CRM to the deal
Common questions
Marketing and sales report different numbers to the board. Fixable?
Yes, and the fix is procedural before it is technical. The numbers differ because the systems count different things under the same words. We get both sides to agree definitions, build the reporting on CRM records both teams can inspect, and document the known gaps with sizes. The credibility comes from the reconciliation, not from prettier charts.
What about the touches we cannot track, podcasts, communities, word of mouth?
Ask, and take the answer seriously. A how-did-you-hear-about-us field, kept free-text and read monthly, reliably surfaces the dark channels the click data cannot see. We run it alongside tracked attribution and report both, because the tracked view alone systematically over-credits search and under-credits everything that made someone search.
Is multi-touch attribution software worth buying?
Usually not before the plumbing exists, and often not after. Most B2B deal volumes are too small for algorithmic models to beat honest first-and-last-touch reporting, and the tools inherit whatever source data quality you feed them. Fix capture, stage tracking and offline conversions first; most teams then find the expensive model adds a decimal place, not a decision.
