An ATF Industry Operations Inspector (IOI) will arrive — sometimes unannounced — and request your A&D book, 4473s, and physical inventory for cross-referencing. They will check that every firearm in your possession has an acquisition entry, every sold firearm has a disposition entry, and that 4473s are on file for every transfer. Having your records in a digital system that generates instant reports dramatically reduces the stress and time involved in an inspection.
