About FFL Boss Extension

It streamlines the FBI LEEP background check process and supports electronic submission of ATF forms through the ATF eForms system. With this extension, FFL Boss and FFL Boss Cloud users can auto-fill and submit LEEP background checks, populate and file supported ATF eForms from existing records, and access additional in‑workflow tools designed to speed up day‑to‑day compliance tasks. It is built to work seamlessly within the existing FFL Boss interface so staff can complete critical steps without leaving our software. FFL Boss is a cloud‑based FFL software platform—no local installation is required. It runs on Windows, macOS, ChromeOS, iPadOS, and other internet‑connected devices with a modern browser.
