“Choose Stripe if you want the most flexible developer-centric API stack and need to embed B2B payments into software or workflows.” Perplexity Sonar · comparative prompt · first choice

“Best For: B2B SaaS, recurring subscriptions, and developer-heavy marketplaces... Unmatched API customization for developers” Gemini 3.5 Flash · comparative prompt · first choice

“If you're a SaaS or platform business → Stripe (or Airwallex for global multi-currency needs) is likely the right fit.” GLM 4.7 FlashX · comparative prompt · first choice
