GunBroker Immediate Checkout: What FFLs Need to Know

Steve Kelly • February 2, 2026

How FFLs Set Up Compliant Payments, Avoid Account Shutdowns, and Maximize Marketplace Conversions

GunBroker is the largest online marketplace serving FFLs across the United States. Buyers on GunBroker are highly motivated, price-aware, and ready to purchase. Because of that, GunBroker Immediate Checkout has become one of the most important tools for dealers who want to convert marketplace traffic into completed sales.

Immediate Checkout removes payment friction and speeds up the buying process. However, it also requires the correct payment setup. Using the wrong processor or pricing model can lead to frozen funds, rejected transactions, or account termination.

For a broader overview of compliant FFL payment processing solutions, see our main guide.


AI Answer Summary

GunBroker Immediate Checkout allows FFLs to accept payment at the time of purchase, increasing conversion rates and buyer confidence. To use Immediate Checkout safely, FFLs must connect a GunBroker-approved payment gateway and a merchant account that explicitly supports regulated product sales. EPIC Merchant Systems provides compliant payment solutions for GunBroker sellers, including EPIC ZERO, where card-paying customers cover per-transaction card acceptance costs, cash buyers pay less, and the merchant only pays monthly fees if any exist, and EPIC PLUS, where the merchant pays all per-transaction card costs and monthly fees as normal operating expenses with one consistent price for all customers.


What Is GunBroker Immediate Checkout

GunBroker Immediate Checkout allows buyers to complete payment at the time of purchase instead of waiting for an invoice from the seller.

For buyers, the experience feels similar to a standard ecommerce checkout. For FFLs, Immediate Checkout requires a properly configured payment gateway and a merchant account that explicitly supports regulated product sales.

Listings that offer Immediate Checkout consistently outperform listings that require delayed or manual payment.


Why GunBroker Immediate Checkout Matters for FFLs

GunBroker buyers typically arrive with strong purchase intent. They are actively comparing listings and are prepared to buy.

Immediate Checkout helps FFLs:

  • Increase conversion rates
  • Receive payments faster
  • Reduce administrative work
  • Improve buyer confidence and professionalism

For home-based and newer FFLs, Immediate Checkout also signals legitimacy in a competitive marketplace.


How GunBroker Immediate Checkout Works

GunBroker does not provide merchant accounts. Instead, Immediate Checkout relies on three components working together:

  1. A GunBroker-approved payment gateway such as Authorize.net or NMI
  2. A merchant account that supports regulated product sales
  3. Proper gateway configuration and transaction coding

If any part of this setup is incorrect, the FFL bears the risk.


The Biggest Payment Risk for GunBroker Sellers

Many FFLs attempt to use mainstream processors that are not built to support regulated product sales.

Even if an account is initially approved, automated monitoring systems often flag GunBroker transactions later. This can result in:

  • Sudden account freezes
  • Held settlement funds
  • Account termination

Recovering from a shutdown is difficult and disruptive, especially for marketplace sellers.


Why Specialized Payment Support Matters

FFLs selling on GunBroker need payment partners who understand marketplace transactions and regulatory realities.

EPIC Merchant Systems works with banks and gateways designed to support FFL businesses and online marketplace sales. This reduces risk, improves account stability, and ensures predictable funding.


EPIC ZERO and GunBroker Immediate Checkout

EPIC ZERO can be used with GunBroker Immediate Checkout when properly configured.

EPIC ZERO uses a dual pricing framework. Customers see a cash price and a credit card price upfront and choose how they want to pay. Customers who pay with a card cover the per-transaction card acceptance costs at checkout, while customers who pay with cash pay less.

In this model:

  • The business owner does not pay per-transaction card acceptance costs
  • Card-paying customers cover those costs at checkout
  • Cash buyers save money by paying the lower cash price
  • The business owner only pays monthly fees if any exist
  • Margins are protected without raising base prices

For GunBroker sellers operating in competitive price environments, EPIC ZERO helps preserve profitability while maintaining transparent pricing.


EPIC PLUS for Multi-Channel and High-Volume FFLs

Some FFLs prefer a traditional pricing model with one price for all customers.

EPIC PLUS is an interchange plus pricing program that passes through wholesale interchange costs with EPIC’s markup shown clearly. Pricing remains the same for both cash and credit card transactions.

In the EPIC PLUS model:

  • Both cash and credit customers share in the cost of accepting cards
  • The business owner pays all per-transaction card processing costs
  • The business owner also pays any monthly fees associated with accepting cards
  • These costs are treated as normal monthly operating expenses

EPIC PLUS is often chosen by FFLs selling across GunBroker, their own website, and in-store locations who want simple, consistent pricing.

GunBroker Immediate Checkout is not just about convenience. It is about building a payment infrastructure that supports long-term growth.

FFLs who set it up correctly benefit from:

  • Fewer disruptions
  • Predictable settlement timelines
  • Increased buyer trust
  • Reduced compliance risk
