Payment Processing

Payment processing is a clear duopoly in AI discovery, with Stripe Terminal and Square capturing nearly identical share of attention across all four engines — Stripe Terminal surfaces in 98% of buyer queries, Square in 91%. PayPal sits a step behind at 89%, while QuickBooks, Chargebee, Recurly, and Checkout.com form a second tier in the 45-64% band. Head-to-head comparisons tell a different story: Tipalti wins more matchups than it loses across 14 comparison queries, yet barely cracks the discovery shortlist. Paddle is the faller — shedding 16 points of AI attention while Birdeye rises 14 points to tie Stripe Terminal in recent evaluation scores. This is a contested category: the shortlist is consolidated around three household names, but evaluation-stage fights scatter across subscription-billing specialists and B2B payment platforms that almost never surface in top-of-funnel discovery prompts.

The shortlist

Across 53 buyer-style "Payment Processing" queries

Stripe Terminal captures eyeballs across all four engines in 98% of discovery prompts about payment processing, with Square (91%) and PayPal (89%) forming a near-tie for runner-up. QuickBooks lands at 64%, visible on every engine but surfacing in fewer than two-thirds of buyer queries. Chargebee, Recurly, and Checkout.com cluster in the 45-57% band, each showing up across ChatGPT, Perplexity, Gemini, and Claude but with less consistency than the top three. The tail stretches long: 26 brands surface in at least one prompt, but only the top seven break 50% share of discovery attention.
