How Credit Card Processing Works: A Guide for High-Risk Merchants

Whether you’re running a peptide business, a CBD shop, or an online firearms store, accepting credit cards is the lifeblood of e-commerce. But what actually happens when a customer swipes, taps, or clicks “Buy Now”? Understanding how credit card processing works helps you make smarter decisions about your payment stack—especially if you operate in a high-risk industry.

Here’s a simplified breakdown of how processing works and why it matters for your business.

The Players in Payment Processing

Several key players are involved in moving money from your customer’s wallet to your business bank account:

What Happens When a Payment is Made?

Let’s break down a typical transaction flow:

1. Authorization

A customer enters their card info on your checkout page.

The payment gateway securely encrypts and forwards that data to the processor.

The processor contacts the card network (e.g., Visa).

The card network requests approval from the issuing bank (e.g., Chase).

The issuing bank checks for available funds or credit and fraud risk.

The transaction is approved or declined in seconds.

2. Batching & Settlement

At the end of the business day, approved transactions are batched together by your processor.

This batch is sent to the acquiring bank, which deposits the funds (minus processing fees) into your business account.

Settlement typically occurs in 1–3 business days.

3. Funding

You receive the net amount after fees and any reserves.
In a high-risk account, your funding may include:
- A rolling reserve (e.g., 10% held for 6 months)
- Delayed settlements
- Higher fees due to risk exposure

The Role of Merchant Accounts

To process credit cards, you need a merchant account—this is NOT the same as your business bank account.

A high-risk merchant account is specially underwritten to support industries with:

If you're in one of these verticals, a standard Stripe or Square account won’t last. They often shut down accounts without warning, freezing your funds and killing your cash flow.

Why Risk Level Affects How You Process

High-risk businesses face unique payment challenges:

Risk Factor	Impact
Chargebacks	Higher fees, rolling reserves, stricter underwriting
Regulatory Compliance	Need for KYC/AML checks, PCI compliance, FFLs, age-gating
Industry Type	Some processors flat-out decline entire categories (firearms, CBD, adult, etc.)
Reputation Risk	Banks don’t want media blowback from controversial sectors

That’s why working with a specialist high-risk processor like High Risk Merchant Bank is critical.
