What we observed in this categoryauto-generated
BILL and Ramp share the category lead with identical visibility scores of 75.0% and composite scores of 56.2, placing them 12.5 percentage points ahead of the next tier (Stampli and Sage at 62.5%). The category average visibility is just 23.1%, meaning both leaders are outperforming the field by more than three times. This concentration at the top is stark: the bottom half of tracked brands sits at or below 25.0% visibility, suggesting AI Overviews are consolidating attention around a small cluster rather than distributing it broadly.
A meaningful divergence exists between being named in AI Overviews and being cited as a source. Sage appears in 62.5% of responses — the joint third-highest visibility — yet carries a 0.0% citation rate, meaning AI describes it but does not direct users to its domain. The same pattern holds for Melio, Coupa, and Yooz. By contrast, Tipalti and Medius achieve citation parity with top-ranked brands despite lower visibility scores, indicating their domains are trusted as reference sources even when they are not prominently featured in narrative answers.
Google AI Overviews is the dominant engine across every brand in this dataset — no brand records a top engine other than Google AI Overviews, confirming that AI visibility in this category is effectively a single-platform phenomenon at present. The top cited external sources include reddit.com, g2.com, and youtube.com alongside niche finance sites like zoneandco.com and fraxion.biz, suggesting Google's AI is anchoring on peer review and community content rather than vendor documentation. Both bill.com and tipalti.com appear in the cited sources list, marking them as the only brands whose own domains serve as reference material.

Sources AI engines trust in this category
Across the 8 buyer-intent queries we ran on accounts payable automation software, these are the domains Google AI Overviews cited most often. If you're not on this list — or if your competitors are — that's a concrete PR / linkbuilding target.
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.
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.
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.
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.
