March 5, 2026 | Edward Ip | Leave a comment Why Gun Shop POS Requirements Are UniqueRunning a firearms retail business is unlike any other retail operation. Beyond the usual inventory and payments, gun shop owners must navigate federal ATF regulations, 4473 form compliance, serialized inventory tracking, and age verification requirements. The wrong POS system doesn’t just cost you money — it can cost you your FFL license. Quick Answer: The best POS systems for gun shops in 2026 are Celerant ($199–$349/month) for established FFLs needing full ATF compliance and multi-location support, and Rapid Gun Systems ($99–$199/month) for independent dealers wanting a purpose-built FFL solution with native FastBound bound book integration.
