What does Merchant Solutions Corp do?

Merchant Solutions Corp is a US-based payment processor and POS reseller. We provide credit card processing, dual-pricing programs, Clover and Square POS systems, smart payment terminals, ACH, and gateway services to restaurants, retail, and service businesses nationwide.

How much does credit card processing cost with MSC?

Our standard interchange-plus pricing starts at interchange + 0.25% + $0.10. Dual-pricing customers pay $0 processing fees because the cash discount is passed to the cardholder. Custom rates apply for high-volume merchants above $250K/year.

Do you offer free POS systems?

Yes. Most merchants qualify for free Clover, Union POS, or Dejavoo placement when enrolled in our dual-pricing or qualifying processing program. Free hardware includes installation, training, and 24/7 US-based support.

How fast can MSC get me set up?

Most single-location merchants are approved within 24-48 hours and live within 3-5 business days. Hardware ships next-day. We handle menu/inventory build, employee setup, and on-site or remote training.

Which payment processors do you work with?

We are processor-agnostic. We place merchants with Fiserv, TSYS, Worldpay, Elavon, Shift4, and Electronic Payment Exchange (EPX) — whichever delivers the best underwriting, rates, and POS fit for your business.

Are you a direct processor or a reseller?

Merchant Solutions Corp is an Independent Sales Organization (ISO) and authorized POS dealer for Clover, Square, Union POS, Dejavoo, Ingenico, PAX, and Payanywhere. We have direct processor partnerships and ISO contracts that let us undercut bank-branded rates.

Internet & Network Requirements for POS Systems | MSC Help Center

Internet & Network Requirements for POS Systems

Important — Done-For-You vs. DIY Installation

Merchant Solutions Corp recommends Done-For-You installation whenever possible. Our team reviews your internet connection, network setup, Wi-Fi coverage, and equipment requirements before deployment to reduce setup issues and downtime.

Merchants who choose Do-It-Yourself installation are responsible for providing a compatible network environment, including internet service, firewall settings, Wi-Fi coverage, and supported accessories. Merchant Solutions Corp cannot guarantee performance or assume responsibility for issues caused by local network configuration, unsupported hardware, or third-party equipment.

Frequently Asked Questions

Will starlink work for my POS?

Yes for single terminals. For full-service restaurants with KDS + handhelds, we recommend a wired fiber/cable connection as a primary with Starlink as backup.

Can I run POS on hotspot only?

For pop-up events and food trucks, yes — most smart terminals work fine on 4G hotspots. For brick-and-mortar, no.
