At a glance
What we observed in this category
Ramp leads the accounts payable software category with a composite score of 70.0, rising from rank 4 to rank 1 after a 37.5-point visibility increase and a 50-point citation gain. Tipalti sits second at 65.0, achieving a perfect 100% citation rate despite lower visibility than Ramp. The gap between these two and the rest of the field is significant: third-placed BILL scores 51.2, and every brand below rank 3 falls under 33.0, confirming that AEO advantage in this category is concentrated at the very top.
The data reveals a clear divergence between visibility and citation across this category. BILL matches Ramp on visibility at 62.5% but converts just 25% of those appearances into citations, while Tipalti converts every appearance. Stampli appears in 37.5% of responses yet earns zero citations, and Medius earns a 50% citation rate with zero visibility appearances, suggesting it is being referenced in answers without being surfaced as a named recommendation. These patterns indicate that appearing in AI responses and being trusted enough to cite are distinct AEO outcomes in this category.
Google AI Mode is the top engine for every brand in this dataset without exception. Among cited sources, youtube.com appears first in the category source list, ahead of brand-owned domains like ramp.com and tipalti.com, suggesting the AI is anchoring on video content alongside vendor sites. Third-party authority sources including gartner.com, zoneandco.com, and makershub.com also feature, which points to review and comparison content playing a material role in how Google AI Mode constructs answers about accounts payable software.

How to read this AEO 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 →
AEO 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 90 days and refresh this page automatically. How AI search ranking works →
