Payment solutions built for your business

Whether you sell online, in person, by phone, or on a subscription, we place the right account type and layer on the features that keep you getting paid. Every account is underwritten around your real business model and the products or services you actually sell, with a payment processor and acquiring bank matched to your transaction volume, chargeback rate, and industry — not a generic risk score.

Aggregator vs dedicated MID

Aggregator model vs. dedicated MID with Gray Merchants

Shared, automated processing pools are convenient — until an algorithm flags your business. A dedicated merchant account trades that convenience for stability.

What merchants say

Built for businesses that got burned

Our processor froze $43,000 in our account with no warning. Gray Merchants had us back up with a stable account within a week.
CEO, CBD Wellness Brand
We were declined by three standard processors before finding Gray Merchants. The underwriting team actually understood our industry.
Founder, Nutraceutical Subscription Brand
Chargebacks were pushing us toward a monitoring program. Their defense team helped us bring the ratio down and keep our account.

Industries

Serving 67+ high-risk industries

Card networks and banks label certain industries “high-risk” for chargebacks, regulation, or reputation. We specialize in exactly those — pairing each account with proactive chargeback prevention to keep it stable. Search yours to see how we underwrite it — each guide covers approval odds, documentation, and the reserve terms to expect.

FAQ

Frequently asked questions

What is a payment ISO, and what does Gray Merchants do?

A payment ISO (independent sales organization) resells merchant services on behalf of acquiring banks and processors. Gray Merchants places dedicated merchant accounts and payment processing for both low-risk and high-risk businesses, matching each merchant to the bank, processor, or acquirer partner best suited to its industry, volume, and risk profile.

What counts as a high-risk industry?

High-risk industries include categories like CBD, nutraceuticals, travel, coaching, software subscriptions, and firearms — any business that mainstream processors decline due to chargeback rates, regulation, or reputation risk. We support 67+ such industries with dedicated high-risk merchant accounts and chargeback prevention built in.

How fast can I get approved?

Most applications receive an underwriting decision in 24–48 hours. Approval time can vary if additional documentation is needed for your industry.

Is there a setup fee?

No. There is a $0 setup fee to apply and get placed with a merchant account.

What is your approval rate?

We approve 99% of qualified applications by matching each business to the bank or acquirer partner best suited to its industry and risk profile.

Will I get my own dedicated merchant ID (MID)?

Yes. Unlike aggregator-style processors that pool many businesses under shared accounts, we place a dedicated MID for your business, which supports long-term account stability.

Can you help if my account was already terminated?

Yes. Many merchants come to us after a termination or freeze. We review your processing history and place a new dedicated account with a partner suited to your situation.

How do I get started?

Apply online in a few minutes or request a custom quote, and a specialist will respond within 4 business hours during our support hours, Monday–Friday, 9:00–18:00 EST.
