Mainstream Merchant Services Fees, Rates & Costs

A Closer Look at The Contract

Cost & Fees Summary
Cancellation Penalties Yes
Monthly & Annual Fees Yes
Processing Rates Interchange-Plus (Variable)
Equipment Leasing Likely

Three-Year Service Agreement

Mainstream Merchant Services offers a three-year contract, based on employee reviews and the available contract document. This agreement automatically renews for successive two-year terms unless canceled with at least 30 days’ written notice before the term’s end. Company representative Chad Rapper highlighted that they provide both Interchange-plus or Cash Discount pricing, tailoring to business owners’ preferences. The markup over Interchange-plus may be variable, as specific rate details weren’t provided.

If service is canceled before the initial three-year term ends or notice is given in the last month of the contract, a termination fee of $250 is applicable. Other fees in the contract include a $20 monthly minimum fee, $20 chargeback fee, $6.95 monthly PCI compliance fee, a $3.95 monthly regulatory fee, among others, within an Interchange-plus pricing framework.

Virtual Terminal and Payment Gateway Pricing

For its virtual terminal and payment gateway services, Mainstream Merchant Services mentions a standard $10 payment gateway fee. Additional costs, such as technical support fees, batch fees, and extra transaction rates, may also apply to these e-commerce services, though specific pricing isn’t publicly detailed.

Contract Clarification

A recent update from a company representative clarified that the virtual terminal fee applies only to users of that specific service. Moreover, they allow contract cancellation within the first 90 days of service without penalties. While this offers a trial opportunity for their systems and support, it doesn’t provide an exit option post the initial 90-day period.

Industry-Average Terms

Mainstream Merchant Services’ fees are in line with industry norms but not as low as the most affordable merchant account providers. The presence of a three-year, auto-renewing contract influences a “B” rating, as long-term commitments can be limiting for merchants. While there are some complaints about the $250 cancellation fee, most customers seem content with their rates and fees.

Should You Work For Them?

Jobs & Marketing Summary
Uses Independent Resellers No

Misleading Marketing No
Discloses All Important Terms No

Inside Sales Team

Mainstream Merchant Services appears to utilize strategic partnerships and in-house, W2-employed sales agents to market its services. We consider this hiring practice to be preferable to the use of independent sales agents, as in-house agents tend to receive more support and training. The total lack of Mainstream Merchant Services reviews regarding the company’s sales team supports the likelihood that its agents are well-trained and held to ethical standards.

This compares favorably to our list of best credit card processors.

Potentially Misdirected Complaints

We have located one complaint that mentions aggressive sales calls, but Mainstream Merchant Services responded to this review and assured the reviewer that the company does not use telemarketers or auto-dialers to sell its services. It could be that this complaint was intended for Main Street Processing, which has a similar name and a history of aggressively cold-calling businesses.

No Misleading Marketing

In particular, Mainstream Merchant Services receives remarkably strong reviews from its employees on, and it’s likely that this satisfaction results in a positive experience for the company’s clients. It is also worth noting that the company does not list any deceptive rate quotes or misleading promotions on its website. However, if you suspect that Mainstream Merchant Services is overcharging you, you can double-check your monthly bill with a third-party statement audit.

Our Mainstream Merchant Services Review Summary

Our Final Thoughts

Mainstream Merchant Services is currently rated as a reliable credit card processing provider based on available data. The company maintains a notably low number of merchant complaints, which indicates overall customer satisfaction. However, its contract terms seem only marginally more competitive than the industry average, suggesting that businesses should weigh these conditions carefully when considering Mainstream for their processing needs.

As its Better Business Bureau profile continues to gather client feedback, our assessment of Mainstream Merchant Services may evolve. In the meantime, prospective clients are advised to compare its pricing with the top overall payment processors to secure the best deal. Conducting thorough research into pricing and service terms will ensure businesses find the ideal fit for their payment processing requirements, balancing reliability with competitive costs.

Location & Ownership

The company is a registered ISO/MSP of Wells Fargo Bank, N.A., Concord, CA. The company’s headquarters can be found at 11720 Amberpark Dr., Alpharetta, GA 30009. The president of Mainstream Merchant Services is Jerome Vignale.

    Pierce & Pierce Millwork

    Our company has been doing business with Mainstream since 2017. At the end of April, a charge back for $4000 was attempted by Mainstream without notification but was blocked by our security we have on our accounts. Mainstream has locked our account without notification and is holding over $100,000.00 of our money. I have not been able to get this resolved or get the President of Mainstream to speak with me over the phone. Today is May 18 2022 and every Credit Card Transaction is still being held by Mainstream.

    • Leandra Perfall

      Mainstream Merchant Services

      Hello, Scott! Happy to get you to the right person regarding your chargeback scenario. Some merchants don’t realize, when a dispute is made against your business, it is the card holder’s BANK that takes the funds back from your account, not the processor (MainStream). And no bank would notify you of this, prior to taking the funds. If that were the case, it would give merchants the opportunity to take their money and close the bank account.
      If you have a dispute against you, you are required to respond to it. Also, since you put a security block on your account, funds won’t deposit until the block is released… Again, another issuing bank action, NOT MainStream. These are legal actions that any processor has to abide by. If you just contact our Help Desk, and get to our Customer Service team, they can assist in getting you over to our chargeback specialists so you can proceed properly with the action against you. All of our merchants are treated the same.. Big and small businesses, with quality customer service, professional care and on legal terms. Hope this helps!

    I utilized Mainstream services since 2015. I retired in 2020, and was charged $39.10 for 13 months (payments automatically taken from my account). When I discovered the charges, I cancelled my account. Discovering at new charge of $250 for an early cancelation fee! I was told that my contract automatically renewed for a 2 year Period after the first 3 years! This sounds like an illegal EVERGREEN clause! I would never do business with with this company again.

    • Leandra Perfall - Regional Sales Manager

      MainStream Merchant Services

      Hi George, any and all concerns regarding early termination fees can be managed by your sales rep at MainStream. We also have 24 hour support for all of your billing needs. Did you not close your account with us when you retired? Was the business closed? We always make accommodations for those who close stores or have a change over in ownerships. Please notify your sales rep and they will work this out with you.
      Every company has a minimum processing fee, if you don’t process cards without cancelling an account, to keep your account active and maintained. This was the small automated fee you were getting monthly. Happy to help with your fees, if you just contact your sales rep to manage this for you. Thanks!

    • Chad


      Hello George, this situation seemed out of the ordinary for us so I also looked into it further. What Leandra was thinking might have been the case did turn out to be accurate which was was that when you retired, we weren’t notified you were no longer going to be processing and service wasn’t canceled so we had no way of knowing you were stopping. As for the cancellation fee, I spoke with our customer support team and I found out who your rep was so you need to reach out to him and he can work with you on that fee.

  • Laser Therapy Health

    We’ve been working with Jeff Carrick and mainstream creidt card merchant for almost 5 years now. They are trustworthy and reliable. As we’ve grown, our rates have gone lower instead of higher. Jeff makes sure we are on an exchange that keeps us at the most cost effective overall processing rate. We’ve been pitched by so many credit card processing firms and banks over the years. We remain loyal to mainstream and Jeff because they do not fluctuate on the processing rate agreed upon. Reliable, trustworthy and helpful 24/7 customer service. If you are a business and and count every penny like we do, you need a mainstream. They have your best interest at heart.

  • aj

    How many companies will come to you with new discounted pricing without you asking? These guys, Chad came to me today and will be lowing my bill without me even asking. Thank you Chad appreciate the great service


    Trudy King, has been taking care of all 6 of our locations.
    We get next day funding at a good rate better than In have seen. But the biggest thing is that if there is a problem or a question she is just a phone call away. I always have an answer within 24 hours. That’s customer service.

  • Aimee Long

    Was having connection issues with my processor. Chad Rapper came out within 30 minutes of my phone call, spent 30 minutes correcting the problem and it’s fixed! He is truly a man of his word and the nicest to deal with!

  • The Fiahermans Wife

    We are very pleased with the services provided by Mainstream merchant services. Our representative Courtney Chason is extremely efficient, warm and friendly. He makes sure we are taken care of as quickly as possible.

  • Charles Wells

    Mainstream saves me considerable money over fees charged by my previous vendor. I also appreciate the personal service of Trudy King and the call center staff that support her oversight of our account. I have confidence knowing I’m supported by folks with proven industry experience who are committed to my satisfaction.

  • Teresa Bajew

    Trudy King with Mainstream has been wonderful! Any time I need something she comes over or makes sure our need is satisfied. You can’t ask for a better rep. We have had numerous companies try and get us to change our processing and we don’t want to because we don’t want to lose Trudy!!!

    • Ruben Espinoza

      Our company, Katy Stone & Gravel Inc. has been a customer of Mainstream for several years now. Our rep, Trudy King is amazing! She has saved us a considerable amount of money and is very hands on with us when we need things. You can’t ask for better than Trudy!

  • Gabriel Ortiz

    Mainstream is a great provider and Trudy is one of the best in customer service. Any questions Trudy is there to help you every step of the way.

    Trudy is very informative in finding out about tips on processing and credit card security.

  • P and P Produce

    I’m very satisfied with mainstream. The service is great, every time I have a problem they are prompt and very friendly. Barbara Skinner is the best she has bent over backwards to help me. I trust her completely. I can call her anytime and she’s there helping me to straighten things out. I’ve been with her about 10 years. We have P and P Produce in Northport Alabama and I want to say thank you Barbara and Mainstream for always being there for me!

  • Eco2 Office

    We are extremely satisfied with our choice to change to Mainstream Merchant Services. Our rep Trudy King helped us with a flawless transition and continues to check-in and confirm our needs are being met.

    An example, our business was recently burglarized and the cowards absconded with some of our banking information. We were required to quickly obtain new business bank account numbers. With a quick call, Trudy not only helped us switch the services to the new accounts.. she also stopped by to check on us.

    We have absolutely no hesitation when recommending Trudy to other businesses and do so often.

  • carol sellers

    we have thoroughly loved Mainstream at the Whistle Stop in Huffman. No pressure good service and good quality. my sales rep is the best Trudy King. She’s an awesome rep for yiur company. She takes good care of us and we THAMK her for that.

  • Brandon Wagner

    Tribeca has been a client of Mainstream for several years. I have always had a great experience from everyone I’ve dealt with. From the initial purchase and set up to tech support, everyone is really helpful. Tech support is always available, but we really never need it. We just switched machines to the new Poynt system, and it was a painless transition, and the machine is so fast we can accept chip cards twice as fast as before. I can’t be happier with Mainstream!

  • Mary Beth Flynn

    Our rep Chad Rapper ( real name) does a great job servicing our account. He is quite quick to respond to our questions & concerns. The initial set up was a little bumpy, working out all the kinks. I was please that he personally went to each of our locations to do the initial set up himself. Even when we switched to new cc machines shortly after joining Mainstream, he himself, again went to each of our locations. Excellent customer service by Chad Rapper.

  • Dorinda obsta

    We have used Mainstream Merchan Services for years. We have the best sales rep, Trudy King, in their company! They honor their word, treat their clients with the utmost respect and do the best merchant services job we have seen in our last 7-years of business.

  • Mike Skinner

    Here at M&S Furniture we are very thankful for Barbara Skinner and the work she does for us. We are able to service more customers because of Mainstream, and if there is ever a problem Mrs. Barbara is always there to help. Mainstream has saved us so much and expanded our range of business.

  • sophie

    I have been using mainstream for one and half years. Jeff help me a lot. Whenever I have troubles, he always help me on time. They provided me two equipment in case there has something happened. I would highly recommend it to you . Thank you Jeff.

  • Dawn

    Our dental practice made the switch to Mainstream Merchant Services and our rep Trudy King made our experience seamless. Any time we have needed help, she has been there to take care of our needs. We really appreciate all she has done to help our practice!

  • Cindy Hartman

    Trudy King introduced me to Mainstream. Mainstream has excellent customer service and great merchant services. Trudy and her team at Mainstream have “streamlined” our credit card transactions so we cut our work time in half! Thank you Trudy and Mainstream!!


    We’ve never experienced service like we have with our rep Chris. We run a very efficient shop and his service along with expertise have help lower our over all costs and if we have any issues (which is very few), he is always there in MINUTES to fix our issues. I would recommend Chris and Mainstream out to any other business in south Florida. There is no comparison!

  • Janice Van Riper

    Chad at Mainstream Merchant Services has been absolutely amazing. Our company has saved a lot of money since switching services. It is so comforting to know that Chad is here whenever I have a problem. I call and he is right there to assist with any glitches we may have. I have an answer to my issues immediately. Very satisfied customer. I recommend Mainstream to all by Business owner friends.

  • Kevin Pietro

    I have used Mainstream Merchant Services for over 5 years now and have always had great customer service and a very reasonable rate and fees. Also, my rep Chad Rapper, has always gone above and beyond to make sure everything runs smoothly with my processor and if I ever have a issue he handles it quickly and professionally. From the initial set up, which he helped walk me through, to any other questions I may have, he is great to work with. I plan to stay with Mainstream for all my credit card processing needs.

  • Piedmont Endodontics

    I am delighted to write this review for Tim Gossage with Mainstream Merchant Services. We presented Tim our merchant service statements for his review and he came back to us with an outstanding savings. His knowledge and expertise in the credit card processing made me feel comfortable with our decision to change merchant services to Mainstream.

    During the exchange of equipment, Tim was at each of our locations to make sure that this transition was seamless. He coordinated times with our computer hardware tech to make sure that our processing through our computers was correctly set up and did not leave until he tested each location.

    His kind and patient personality was an asset when he trained the staff on the use of the new machine. He thoroughly went through the instructions and was knowledgeable when questions were asked.

    I would recommend Tim Gossage to any of our colleagues. I have appreciated his honesty and determination to see that our needs are met.

  • Jodi Behrens

    I would like to say thank you to Chad at Mainstream Merchant Services!

    Chad was so professional, honest, and on the up and up! I felt very comfortable giving him my info and he was honest by saying “we may or may not be able to save you money!” Guess what, he saved us hundreds! We were so pleased, not only with the savings but also with the continued support the company and staff offers.

  • Jasmin Harris

    My restaurants, The Original Pancake Houses Poway and Temecula made the switch to Mainstream Merchant Services in 2013 and we could not be more satisfied with our decision. In our first year we saved upwards of $12,000. The colossal savings, same day deposits and guaranteed rates is what helped make the decision for us to switch but their account management is why we stay. Our sales representative made the switch seamless and has helped with the recent EMV integration. Any time I have had to speak to customer service, Alison has handled my request with the utmost professionalism. Great company!
