MSP Definition

Merchant Account MSP Explained:

What is an MSP? “MSP” stands for “MasterCard Service Provider” and is a formal designation that companies must have in order to resell MasterCard Credit Card Processing under their own company names. MasterCard displays its registered and approved MSPs on the MasterCard Service Provider List and merchants are advised to only work with registered MSPs. Visa has a similar certification called an “ISO.”

MSPs represent an Acquiring Bank, or Processor, or both. MSPs are also allowed to set terms of their own merchant account contracts and mark up processing rates and fees. Although a Processor can also be an MSP, most MSPs are solely sales organizations that act as “middle men” that pair point-of-sale solutions (terminals, payment gateways, mobile accessories, etc.) with merchant account providers and processors.

Why I'm Qualified to Write About Credit Card Processing and Merchant Account Services

I'm a former credit card processing sales director who left the industry because I didn't like how it takes advantage of small business owners. It feeds like a leech on businesses and thrives by imposing fees that are nearly impossible to comprehend. Seeing a need for change, I left and built this website help business owners better understand the industry, research merchant services providers, and get refunds of excessive merchant account fees. My experience of working "behind the curtain" in the industry, and using that knowledge for good, has resulted in millions of dollars returned to hard-working small business owners as well as enterprise-level companies.

From the time that I starting working in the merchant services industry to when I left to create this website, I've been on the pulse of payments for nearly 15 years. It didn't seem fair to keep this "insider" knowledge to myself. To lift the fog, I've reviewed hundreds of companies, read thousands of user reviews, and learned the pricing tricks of every provider. If you have questions about credit card processing, you can find the answers on this website.

    I have been researching entry into the payment processing industry. My company would like to be positioned as close as possible to the card industry networks. Although it is difficult to find clearly detailed information on the subject, it appears impossible to contract directly with MasterCard or Visa. It looks like you have to be sponsored by a financial institution. This confuses me. Outside of the card networks and the sponsor bank, what role does the ISO perform in payment processing besides providing the merchant with payment card equipment?
