Closed-loop reporting connects marketing activity through to closed revenue by linking marketing systems with the CRM, so you can see which campaigns produced actual customers. It closes the gap between what marketing generates and what sales closes, making marketing accountable to revenue.
Without closed-loop reporting, marketing reports stop at the lead and sales reports start at the opportunity, and nobody can see the whole line. That gap is where the is-marketing-working argument lives forever, because neither side has the full picture. Connecting the two is what ends the argument with evidence instead of opinion.
Example:
Linking campaign data to the CRM lets you see that one campaign produced 40 leads and three closed deals, while another produced 200 leads and none.
What does closed-loop reporting require?
A connection between marketing systems and the CRM, with consistent data, so a lead can be traced from its source through to a closed deal.
Why does closed-loop reporting matter?
It makes marketing accountable to revenue rather than leads, replacing opinion about what works with evidence traced to closed deals.
