Payment Hub Vendors: Honest Comparison for Businesses That Actually Process Money
Not every payment hub vendor fits every business. This page breaks down the real options — pricing, hidden fees, integration depth, and which type of San Diego operation each vendor actually serves well. No affiliate bias. No fluff. Operator-to-operator.
⚡ Quick Answer — What Payment Hub Vendors Should You Actually Consider?
- Stripe (with Stripe Treasury): Best for tech-forward SMBs and anyone building custom checkout flows. True payment hub capabilities — payouts, issuing, ACH, cards. Dev-heavy but powerful. 2.9% + 30¢ standard.
- Adyen: Enterprise-grade payment hub used by large retailers and platforms. Interchange++ pricing is genuinely cheaper at volume (often 0.3–0.8% + interchange) but requires volume ($1M+/yr) and technical integration to unlock value.
- PayFac-as-a-Service vendors (Stripe Connect, Payrix, Infinicept): Right fit if you're a software platform collecting payments on behalf of sub-merchants — think local SaaS or marketplace. Payrix/Infinicept give you more control, Stripe Connect is fastest to launch.
- Gravity Payments (local HQ in Seattle, strong San Diego presence): Operator-friendly flat-rate and interchange-plus for brick-and-mortar. No per-transaction fee games. Better human support than Stripe for non-technical owners in Encinitas, Solana Beach, Del Mar corridors.
