The rankings provided by AI engines are influenced significantly by the sources they reference most.

At a glance
What we observed in this category
BILL leads the accounts payable software category with a composite score of 50.0, exactly double Stampli's score of 45.0 and well ahead of Tipalti at 36.2. The category average visibility sits at just 8.1 percent, making BILL's 50.0 percent visibility an extreme outlier. BILL also recently rose from rank 2 to rank 1, gaining 12.5 visibility points and 25.0 citation points in the latest period, which reinforces the concentration of AI attention at the very top of this category.
A clear divergence exists between being named and being trusted as a source. Stampli and Tipalti both hold citation rates of 62.5 percent, higher than BILL's 50.0 percent citation rate, yet both rank below BILL on composite score. Tipalti's own domain appears directly in the top cited sources list, suggesting AI is pulling from its content even as its visibility score dropped 25 points from the prior period. Melio presents the opposite pattern, holding 12.5 percent visibility but earning zero citations, meaning it is mentioned but not sourced.
Google AI Mode is the top engine for every brand in the top 10, indicating this category's AI visibility is entirely concentrated on one engine. The top cited sources include youtube.com and third-party domains such as makershub.com, conseroglobal.com, zoneandco.com, blog.approvalmax.com, and highradius.com alongside brand-owned domains tipalti.com and stampli.com. This pattern suggests Google AI Mode is anchoring on a mix of independent review and commentary sites rather than relying solely on vendor-owned content.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
