Payment Processing in Charleston, South Carolina | Save on Credit Card Fees
Payment Processing in Charleston, South Carolina: A Local Business Guide for 2026
Charleston is one of America's most beloved cities, with a James Beard Award-winning food scene, booming tech sector on the Digital Corridor, and billions in annual tourism.
With a population of 150K, Charleston supports a thriving business community across restaurants and James Beard-winning dining, tourism and hospitality, tech companies on the Digital Corridor, and more. If you're a Charleston business owner, there's a good chance you're overpaying for credit card processing—and it's costing you thousands every year.
Why Charleston Businesses Overpay for Payment Processing
The payment processing industry is designed to confuse merchants. Big-name processors like Square, Clover, and Toast attract Charleston business owners with simple-sounding pricing—but "simple" almost always means "expensive."
Here's the reality:
- Flat-rate processors charge 2.6%–3.5% on every transaction, regardless of the actual cost
- The real interchange rate on most card transactions is just 1.5%–2.1%
- That markup goes straight to the processor—not back into your Charleston business
For a Charleston business processing $25,000/month, the difference between flat-rate and interchange-plus pricing can mean $3,300+ per year in unnecessary fees. That's money you could spend on hiring, marketing, or improving your business in Downtown or anywhere else in Charleston.
