About

Affinity24 is a family-run retail ISO in Tustin supporting roughly 1,000 merchant accounts nationwide. We handle credit card and ACH processing, POS hardware and gateways, virtual terminals, and invoicing for retail, restaurants, e-commerce, professional services, and nonprofits. Most owners come to us because their effective rate keeps climbing and nobody will explain why. We pull the statement apart, look at dual pricing and cash discounting, and give straight answers. Honest pricing, real support, no surprises.
