At a glance
What we observed in this categoryauto-generated
Stripe and Checkout.com share the top rank with identical visibility scores of 25.0% and composite scores of 17.5, both running more than five times the category average visibility of 4.4%. The gap between these two leaders and every other brand is significant: Square sits at 12.5% and Bolt and Adyen trail further, meaning the top two brands together account for half of all observed AI visibility in a 20-brand category. This concentration at the top is a structural pattern worth noting for any brand currently outside the top three.
A clear divergence exists between being named and being cited. Stripe and Checkout.com each hold 25.0% visibility but carry 0.0% citation rates, meaning Google AI Mode mentions them without linking back to their domains. Square is the only brand in the top five where visibility and citation align, both sitting at 12.5%. Airwallex presents the inverse case: 0.0% visibility but a 12.5% citation rate, suggesting its domain is being referenced as a source without the brand itself appearing in AI-generated answers.
All brands in this audit record Google AI Mode as their top engine, confirming that this category's AI visibility landscape is entirely anchored on a single engine. The cited sources Google AI Mode draws on include review aggregators such as G2 and Capterra, media outlets such as Forbes and PCMag, and less obvious domains such as awayco.com and manh.com. YouTube also appears as a top cited source, indicating that video content is being indexed alongside editorial and review content when the AI constructs checkout software responses.

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.
