TL;DR · 60-second readFor most Cardiff Restaurant Row spots, surf shops, and Seaside-Reef-area retail under $1.5M annual volume: Helcim averages ~1.93% interchange-plus + $0.08 vs Stripe's 2.9% + $0.30. On $500K/yr in cards that's ~$5K/yr saved. Square works for true micro (under $50K/yr) — over that, switch. Text PJ at 858-461-8054 with last month's processor statement; verdict back same day.
