Best payment gateway for gunbroker

AI summary

Authorize.net is the best default for established merchants; choose TacticalPay or EBizCharge when specialized high-risk underwriting or interchange-plus fee optimization matters. Mainstream processors automatically ban firearms transactions, requiring specialized platforms for GunBroker Immediate Checkout compatibility. While Authorize.net paired with an approved processor offers the most universally supported gateway setup, alternative high-risk providers like Bankful, Zen Payments, EPIC Merchant Systems, and PayKings deliver tailored solutions for firearms compliance and faster underwriting approvals. Casual sellers should bypass monthly gateway fees entirely and use standard offline checkout methods instead.

What is the best payment gateway for gunbroker?

Collected Jul 26, 2026, 2:34 PM UTC

If you're selling on GunBroker, the "best" payment gateway depends on whether you're an individual seller or a business/FFL.

For most FFLs and high-volume sellers, these are the strongest options currently supported by GunBroker:

  1. Authorize.net – The most widely used option.
  1. NMI (Network Merchants Inc.)
  1. EBizCharge
  • GunBroker lists it as one of its preferred merchant processors.
  • Good customer support and designed for businesses. support.gunbroker.com
  1. Fort Point Payments or Inovio
  • Both specialize in higher-risk industries, including firearms.
  • Worth considering if you've had difficulty getting approved elsewhere. support.gunbroker.com

If you're an individual seller

If you only sell occasionally, paying for a merchant account and gateway often isn't worth the monthly cost. Many casual GunBroker sellers simply use Standard Checkout and accept:

  • USPS Money Orders
  • Certified checks
  • Other payment methods that comply with GunBroker's policies

Immediate Checkout with credit cards generally requires a supported merchant account and payment gateway. support.gunbroker.com

Important

GunBroker specifically prohibits using peer-to-peer payment services such as PayPal, Venmo, Zelle, Cash App, Apple Pay, and Google Pay for firearm, firearm parts, accessories, or ammunition transactions because doing so violates those services' terms and GunBroker's marketplace rules. support.gunbroker.com

Recommendation:

  • Small FFL or gun shop: Authorize.net + a firearm-friendly merchant processor is the safest, most established combination.
  • Growing online business: NMI with a firearm-friendly processor offers excellent flexibility.
  • Occasional private seller: Skip the gateway and use Standard Checkout with approved offline payment methods unless your sales volume justifies the extra cost.

If you tell me whether you're:

  • an individual seller or an FFL/business, and
  • roughly how many sales you expect per month,

I can recommend the most cost-effective setup.
