What is NMI

NMI stands for Network Merchants Inc. which is a DBA of Network Merchants LLC. For clients of BigCommerce, WooCommerce, or Shopify among others it has become a premier payment gateway provider – especially for merchants deemed “High Risk” by the industry. NMI has some unique patented features like its multi-merchant account balancing function which allows for more than one merchant account under one login. As a widely compatible, full-featured payment gateway. NMI performs well for our high-risk merchants. The payment processing options through NMI include recurring billing, the ability to manage multiple accounts through a single interface (including their proprietary ATRI multi-merchant account balancing system), as well as a PCI compliant customer vault storage infrastructure that allows you maintain accurate records for return customers.

These features make NMI the “go to” payment gateway for traditional, high risk, DR/ direct response merchants, catalog merchants, electronic cigarette /e-vapor merchants, telemarketing companies, biz-ops, affiliate-based or MLM companies, along with complex, multi-site e-commerce merchants. NMI integrates with most popular carts such as BigCommerce, CiviCRM, CubeCart, Ecwid, multiple WordPress solutions, Mijireh, Infusionsoft, LimeLight, Konnektive, Magento, osCommerce, Shopify, WHMCSVolusion, high-risk Weebly merchants, WooCommerce and dozens more. You can view an expansive list of NMI compatible shopping carts and software suites here.

Top features of the Network Merchants payment gateway

NMI’s ATRI or Multi Merchant Account Balancing

ATRI stands for advanced transaction routing interface and is a proprietary feature only available through NMI resellers and partners. The NMI ATRI allows merchants to route sales through multiple accounts, using multiple processors, all through a single gateway login.

The NMI ATRI feature permits automated routing based on product name, merchant account, risk category, sale amount, or even based on a percentage of gross sales amounts to assist merchants who need to add multiple merchant accounts because of volume cap limits with their primary processor.

ATRI is an option as some online, high-risk, or direct response (DR) merchants have multiple merchant accounts for various campaigns and want to manage them all through one login and route their transactions to the correct merchant account automatically. The NMI ATRI allows you to do this in a natural, manageable way.

High-risk merchants often need to process some products or campaigns through higher cost “high-risk” accounts, but run other products through lower cost “low-risk” merchant accounts as a cost-saving measure. When using any multi-merchant account balancing interface, it is essential to make sure you do not violate any rules with the card brands, regulators, or your processor. It’s always a good idea to check in from time to time and keep your processor up to date with your current business practices. Often we have seen a high-risk processor allow sales under a specific dollar amount through their merchant account, for example, a $500 cap, but not enable the purchase of higher cost packages through their merchant ID. In these cases, many merchants have found a second merchant account, often at a higher % rate to run these higher risk sales.

Transaction routing and load balancing is best when done with your credit card processor’s blessings and should only be done with precise, accurate credit card descriptors. ATRI, when done correctly, allows processors only to take products they want and enables merchants to be cost-efficient while managing the routing of transactions automatically and seamlessly using NMI’s automatic transaction routing.

Payment gateway transaction routing may sound complicated, but it is as simple as typing the thresholds into the NMI gateway and selecting which transactions you want to go to which merchant account. Reach out to us anytime to learn more.

Get NMI’s ATRI load balancing features through a trusted NMI reseller

It is important to get your gateway from an independent reseller, like us, if you want to manage multiple accounts from one gateway. If you get your gateway from the processor, they likely will not be able to provide you access to the account balancing features as credit card processors do not usually allow competitor’s merchant accounts to be boarded on gateways they provide. ATRI is a feature that needs to be “turned on,” and resellers like us have the experience and ability to help merchants balance multiple credit card processors when appropriate. We are experienced, responsive and have an A+ rating with the BBB. Let us know how we can help.

Manage multiple web properties in one place

NMI allows you to operate multiple e-commerce sites, products and merchant accounts through one streamlined gateway interface.

If you want to manage multiple websites, through more than one merchant account, using NMI as your gateway will allow you to use one username and password to access all your gateway activity and report on all your sales activity from one place all while routing transactions to the correct merchant account.

ACH – Simplified online check acceptance

We offer a simple, streamlined way to add ACH based online check acceptance to your website all through the same interface that you use to accept credit cards. You can set up automated recurring ACH payments from your customers to simplify your monthly billings. ACH is often much less expensive than taking credit cards and may increase your site conversions too. Contact us to learn more!

NMI Customer Vault

NMI’s Customer Vault allows merchants to store their customers’ cardholder data such as credit card number, expiration date, billing address, and multiple shipping addresses in one, secure, PCI compliant environment.

Returning customers can save the hassle of having to re-enter their information on your site which results in happier customers for you. Making the checkout and returning customer purchase process easier produces more repeat business.

You can also charge your repeat customer customers through the virtual terminal without the added liability of viewing sensitive personal and cardholder data.

NMI Recurring Billing

NMI’s recurring billing feature allows merchants like you to bill your clients on a regular recurring basis for as long as required. The system and processes are PCI compliant and always updated with the latest security advances helping protect your business and your customers.


NMI’s Quick Click a simplified checkout system that for some merchants without complex offerings can allow them to avoid using 3rd party carts altogether. QuickClick buttons are added to your site using HTML that is generated by logging into to your NMI account and using the QuickClick HTML generator.
