The gap between sourced and influenced is where budget battles live
Conflating sourced and influenced is the source of most attribution disputes between marketing and sales. The two metrics answer different questions. When marketing reports a large influenced number and sales disputes the credit, the argument is usually about whether "touching" a deal is the same as "creating" it.Marketing-sourced revenue is the conservative answer. It asks: where did this deal come from before sales got involved? If the answer is a marketing channel, marketing gets credit. If a rep sourced it through outbound, marketing gets none, even if the prospect later engaged with content.
Marketing-influenced revenue asks: did marketing interact with this deal at any point? The bar is much lower. In practice, most enterprise deals will have at least one marketing touchpoint because the buying process includes research, event attendance, and content consumption that marketing touches even when it did not originate the relationship.When each metric is useful
| Metric | Best used for | Caution |
|---|---|---|
| Sourced revenue | Budget justification, demand gen ROI, headcount requests | Undercounts marketing's role in complex, long-cycle deals |
| Influenced revenue | Showing breadth of marketing contribution, content ROI | Can be inflated by any minor touchpoint; harder to defend |
How attribution model choice changes both numbers
The same CRM data can produce very different sourced and influenced numbers depending on the attribution model applied. First-touch models maximize sourced credit by giving all value to the originating touch. Last-touch models often shift credit to sales-adjacent touches near close, reducing sourced credit for earlier marketing activity. Multi-touch attribution distributes credit across all touches, which tends to produce a higher influenced number and a more defensible sourced number.
Before reporting either metric, confirm that the underlying marketing attribution model is documented and applied consistently. Changing models mid-year creates comparability problems that undermine the entire measurement.
Building a defensible marketing contribution story
Sourced revenue is the floor, the minimum impact marketing had. Influenced revenue is the ceiling, the maximum plausible contribution. The real number sits somewhere between them and varies by deal size, sales cycle length, and how much the buying committee self-educates before engaging with sales.
Track both metrics over time and watch for the ratio between them. If sourced revenue is declining as a share of total pipeline while influenced stays flat, it may indicate that inbound demand generation is weakening even as marketing continues to appear in active deals. See also revenue attribution for how to structure the underlying data model before running either calculation.
Why the two numbers rarely reconcile
Sourced and influenced are answering different questions, and the gap between them is usually treated as a measurement problem when it is a definitional one.
| Marketing sourced | Marketing influenced | |
|---|---|---|
| Counts | Opportunities marketing created | Opportunities marketing touched |
| Credit | All or nothing | Shared, by some rule |
| Typical share | Smaller, defensible | Larger, contested |
| Fails when | Attribution window is arbitrary | The touch threshold is undefined |
The requirement that decides whether either number survives a board meeting
Both metrics are model outputs once any multi-touch logic is applied, and the constraint on model outputs is traceability rather than accuracy. A figure attributing a share of revenue to marketing will be challenged, and if it cannot be followed back to the records that produced it then validating it costs as much as building the analysis by hand.
That is the general gap across AI and analytics in revenue reporting. The output needs to point back to the point of truth that produced it, which requires a semantic layer fixing what each metric means before any model is asked anything. Without it, two slightly different questions return two different numbers and both look authoritative.
Practical guard: publish the definition alongside the number, including the attribution window and the touch threshold, and keep both stable across periods. A metric whose definition moves cannot be trended, and trending is the only comparison that means anything.

Frequently Asked Questions
What counts as marketing-sourced revenue?
A deal is marketing-sourced when the first meaningful contact with the buying company was generated by a marketing activity, such as an inbound form fill, content download, paid ad click, or event registration, before any sales outreach occurred. The lead originated in marketing's channel, and the deal can be traced back to that origin point.
What is the practical difference between sourced and influenced attribution?
Sourced attribution gives marketing full credit for only the deals it originated. Influenced attribution gives marketing some credit for every deal where any marketing touchpoint appeared. The influenced number will almost always be larger, sometimes dramatically so, because most deals in a modern buying cycle encounter at least one piece of content or one ad.
Which metric should go in a board deck?
Sourced revenue is the most defensible metric for justifying marketing budget against direct pipeline creation. Influenced revenue shows marketing's broader role in the buying journey. Present both with clear definitions, and be explicit about the attribution model underlying each number so the board is comparing consistent figures period over period.
What is the difference between marketing sourced and marketing influenced?
Sourced counts opportunities marketing created and is all-or-nothing. Influenced counts opportunities marketing touched and shares credit by some rule. The influenced figure is larger and more contested because touched is rarely defined precisely.
Why do sourced and influenced numbers not reconcile?
Because they answer different questions and usually use different definitions of a qualifying touch. Publish the attribution window and the touch threshold alongside the number, and keep both stable so the series can be trended.
