Can you integrate Stripe / Square / Amex Open Pay / Affirm / Klarna for NYC stores?

Yes, all of them, and most have NYC offices or HQs. Stripe: large NYC office, Stripe Elements + Apple Pay + 3DS2 + Stripe Connect for multi-vendor, easiest for SoHo DTC. Square: NYC office, online + retail POS unification, popular with Williamsburg / DUMBO small retailers. American Express Open Pay: Amex HQ is in NYC, the killer B2B Magento rail, Net-30 invoicing with Amex-backed credit, perfect for Garment District wholesalers and FiDi B2B. JPMorgan Chase WePay: NYC-HQ, good for fashion DTC with Chase merchant accounts. Mastercard: HQ in Purchase NY (30 min north). Affirm: NYC office, BNPL leader for furniture / apparel / electronics > $100. Klarna USA HQ is NYC + Columbus OH: BNPL specialist for apparel + beauty DTC. Bread Financial: NYC HQ, BNPL + private-label credit. Adyen NYC: unified online + retail platform for high-AOV stores. We typically wire Stripe + Amex Open Pay + Affirm + Klarna USA as the four-rail NYC default.
