At Host Merchant Services, we’ve made the American Express acceptance program easier than ever. Host Merchant Services’ customers can now process AmEx transactions exactly like Visa or MasterCard under one unified merchant account.
That means one contract, one monthly statement, and one deposit for all card sales, which simplifies reconciliation and support. With our integrated OptBlue solution, you don’t need a separate AmEx account or extra paperwork.
American Express customers are known for strong brand loyalty and higher-than-average spending. In the U.S., AmEx cardholders spend approximately 1.7× more per transaction compared to other card brands. They also shop more frequently and expect merchants to accept their preferred card.
With American Express accepted by 99% of U.S. merchants that take credit cards, it’s now considered a standard part of the payment mix. If your business doesn’t take AmEx, you risk turning away high-value customers.
With Host Merchant Services’ support, getting set up is easy. Our team will enable AmEx acceptance on your existing account and ensure your terminals or gateways are configured. You won’t need to sign a separate AmEx contract. We also provide AmEx signage and support, so you can start swiping AmEx cards seamlessly.
Across industries, the standard value drivers are clear: merchants don’t need a separate American Express merchant account, which accelerates onboarding and reduces complexity. Unified reporting, funding, and support through Host Merchant Services cut administrative overhead as volume scales or demand shifts.
At the same time, businesses unlock access to a desirable segment of premium spenders, and the single point of contact for AmEx questions and chargebacks ensures clarity and consistency in day-to-day operations.
OptBlue via Host Merchant Services is ideal across industries, including (but not limited to):
Accepting American Express through Host Merchant Services via OptBlue delivers measurable value across business types, starting with retailers. Premium AmEx cardholders tend to carry higher average order values, so by offering American Express as a payment option, seamlessly integrated into the existing Host Merchant Services processing relationship, retailers can capture bigger baskets and drive repeat visits.
The combination of increased spend from rewards-driven shoppers and simplified operations (one unified statement and funding stream) means less back-office friction even as the mix of payment types grows.
In restaurants and hospitality, guests celebrating special occasions or conducting business meals often prefer using premium cards like American Express. By accepting AmEx through Host Merchant Services, establishments can serve higher-spend diners without checkout friction, improving guest satisfaction while subtly lifting average check sizes.
Because support and dispute handling for AmEx flows through Host Merchant Services, staff don’t have to juggle multiple channels when issues arise, keeping service smooth and operations lean.
For e-commerce merchants, payment method availability is a conversion lever. Showing “We accept American Express” alongside other major cards reduces cart abandonment among high-intent shoppers who filter for full brand support, particularly business and premium customers.
Since AmEx transactions are funded on the same cadence as other brands under Host Merchant Services’s OptBlue handling, online merchants also benefit from consistent cash flow and reconciliation, making growth and seasonality easier to manage.
Professional and B2B service providers gain credibility and remove friction by accepting corporate and business American Express cards through Host Merchant Services. Clients who expense services want convenience; supporting their preferred AmEx payment method makes paying easier and reinforces a modern, client-centric image.
The unified reporting and funding stream simplifies back-office accounting, helping service firms keep their financial workflows clean without needing separate AmEx agreements or systems.

OptBlue is American Express’s program that lets participating third-party processors (like Host Merchant Services) bundle American Express acceptance into the same merchant relationship used for other card brands.
Rather than requiring merchants to open and maintain a separate AmEx merchant account, OptBlue lets Host Merchant Services process, settle, and support AmEx transactions directly on behalf of the merchant, creating a unified experience.
When a merchant accepts American Express via OptBlue through Host Merchant Services:
Wholesale/discount rates for AmEx transactions under OptBlue are negotiated directly with the Host Merchant Services team, assuring you receive more transparent and competitive pricing models such as interchange-plus or defined bundled rates, rather than the historically higher fixed AmEx-only fees.
Merchants benefit from pricing visibility because Host Merchant Services surfaces the underlying AmEx OptBlue wholesale components in their rate disclosures, enabling reconciliation and cost comparison.
Accepting AmEx through Host Merchant Services doesn’t require any additional contracts or merchant numbers. Once activated, your existing terminal, POS system, or payment gateway will begin accepting AmEx just like any other card.
Steps to enable American Express with Host Merchant Services:
Most businesses can begin accepting AmEx within one business day.
AmEx Cardmembers are a lucrative customer group – they spend more per visit and are highly brand-loyal. About 99% of U.S. merchants accept AmEx, so by doing so, you won’t miss sales from these customers. In short, it can increase revenue and customer satisfaction.
Host Merchant Services participates in AmEx’s OptBlue program, which lets us offer competitive AmEx rates. While AmEx interchange fees are still slightly higher than Visa/Mastercard, OptBlue often narrows the gap. Many merchants find the extra revenue from AmEx customers easily offsets the slight fee difference. Host Merchant Services always strives to keep pricing transparent and fair.
No. We’ve integrated AmEx into the Host Merchant Services platform, so your current merchant account will cover AmEx as well. Thanks to OptBlue, all AmEx sales go through Host Merchant Services under your existing agreement. You’ll still see detailed AmEx transactions on your statement, but you won’t have to manage a separate AmEx contract or statement.
Contact your Host Merchant Services representative. We’ll activate AmEx processing on your account and update your terminal or gateway settings. As American Express and our partner acquirers describe, this is a “one-stop solution” so you can accept AmEx just like any other card. We’ll also provide AmEx decals and answer any questions, making the transition quick and easy.
