Integrate Fast. Enhance Experience. Monetize Payments.

Bank Sponsorship

Having a partnership with a sponsor bank is an integral part of accepting payments. However, the process
of developing a relationship with a sponsor bank requires a large investment of both time and dollars.
Leverage our relationship with the largest sponsor bank in the nation so you don’t have to.

Omni Bank Sponsorship Steps With Images

Get Started Faster

Avoid the process of establishing a relationship with a sponsor bank – through our partnership, you will have access to the tools required to process payments in a matter of days, not years.

Alleviate costs

Building a partnership with a sponsor bank is a long and complicated process. A process that requires so much time and money that the majority of a business’s finances need to be allocated for a single partnership. Remove all of that from your plate and start accepting payments with little to no financial investment on your end.

Offer better pricing for your customers

When merchants go directly to a sponsor bank for payment processing, they don’t have much room for negotiating their rates and many times end up paying a lot more in fees than necessary. Leverage our partnership to provide your customers with the lowest rates in the industry.


We’ve built an easy to use enrollment platform that brings all FINCEN regulations to the forefront,
using a single API. Avoid days of underwriting for your customers and give them the ability to
process payments within 20 minutes of getting started.

Alleviate Enrollment Costs

We validate each business using AML, KYC, Credit Check, OFAC, and more.

Avoid the costs of purchasing multiple tools and hiring a team of underwriting analysts; enroll your merchants quickly and securely, with a single API.

Enroll the way you want

We’ve been able to build the ideal merchant scorecard so we can expedite the enrollment process and provide your customers with payment acceptance days faster than the industry average.

• Enrollment API – Enable your customers to sign up for payment processing directly from your app

• Co-Branded Landing Page – Our marketing team will provide you with a custom landing page branded to your business.

• White Glove Service – Provide your customers with a white glove experience and sign up for them using Omni Connect.

Risk Management

PCI Compliance and risk management are only becoming more complicated. Stay out of the PCI Scope
and avoid having to hire risk analysts; we will take on the risk of accepting payments for you.

Don’t worry about hiring a team of analysts

Avoid having to employ a team of underwriters and risk analysts to monitor the transactions in your platform. Our risk team is here to validate and monitor all of the transactions that are processed on your platform, so you and your users can rest easy knowing you’re protected.

Manage disputes in your platform with the Dispute Manager API

Provide your customers with the ability to view and respond to chargebacks from your platform, in real-time.

The traditional process for managing chargebacks is time-consuming, confusing, and many times merchants miss the opportunity to respond due to simply not receiving their notice in time.

Expedite the chargeback process and provide your customers with a better chance of successfully overcoming the dispute with enhanced data and reporting.

Safe and Secure

All of our products are designed to be secure and compliant with PCI from a deep architecture standpoint.

“HindSite is delighted with our partnership with Fattmerchant. They have been an excellent business to work with. Three different HindSite teams have worked with Fattmerchant (Developers, Marketing and or Customer Opps). Each team has told me what a joy it is to work with Fattmerchant. They are responsive, professional and helpful. Most importantly I have heard the exact same things from our customers. Prior to the partnership, our clients didn’t have a way to take payments within our platform. Fattmerchant has solved this pain point.”
