When the ATF publishes its inspection results each year, the same categories of violations dominate the list. They are not smuggling rings or straw purchases. They are recordkeeping errors: entries made late, dispositions never recorded, and inventory that does not match the book.
That should be encouraging, because every one of those findings is preventable with process. Here are the mistakes that actually generate violation findings, roughly in the order investigators encounter them, and what a clean process looks like for each.
1. Late Acquisition Entries
The regulation gives you until the close of the next business day to record a firearm you received. Investigators check this by comparing your receiving documents, distributor invoices, packing slips, and transfer paperwork, against the dates in your entries. A pattern of entries dated days after receipt is one of the most commonly cited violations in the country.
The cause is almost always batching: guns get received, tagged, and priced, and the recordkeeping is saved for a quiet moment that never comes. The fix is structural, not motivational. When the receiving workflow itself creates the A&D entry, there is no separate step to postpone.
2. Dispositions Never Recorded
A gun sells, the 4473 gets completed, the background check clears, and the disposition entry never happens. Months later the book says the firearm is still in inventory. This is how honest stores end up with dozens of "missing" firearms during an inspection: the guns are not missing, the entries are.
Unrecorded dispositions are treated more seriously than late acquisitions because an open entry with no firearm looks identical, on paper, to a theft or an off-book transfer. The investigator cannot tell the difference until the paper trail is reconstructed, and reconstructing it during an inspection is the worst possible time.
3. Inventory That Does Not Match the Book
The core of every compliance inspection is reconciliation: open entries against physical firearms. Both directions matter. A firearm with no entry suggests off-book acquisitions. An entry with no firearm suggests unrecorded dispositions or loss. Either way, the discrepancy count is the headline number in the inspection report.
Stores that run their own cycle counts, monthly for high-volume stores, quarterly at minimum, catch these drifts while they are still one or two guns and fixable. Stores that never self-audit find out at inspection time, when the count is in the dozens. Our audit readiness review walks through exactly this reconciliation.
4. Incomplete Entry Fields
Every entry needs the full identification of the firearm: manufacturer or importer, model, serial number, type, and caliber or gauge, plus the source or recipient. Blank model fields, missing calibers, and "see invoice" shortcuts are all citable. So are transposed serial numbers, which are worse than blanks because they create a phantom firearm that can never be reconciled.
Serial numbers should be entered by scan or by double-blind confirmation, never typed once from memory across the counter. A single transposed digit follows that gun through every subsequent record.
5. Corrections That Destroy the Original Entry
Mistakes in the book are expected. Erasing them is the violation. On paper, the accepted method is a single line through the error with the correction alongside, so the original remains legible. Electronically, ATF Ruling 2016-1 requires the same principle: the system must preserve the original entry and show what changed. Software that lets anyone silently overwrite a record fails the ruling, which is why an ordinary spreadsheet is a poor fit for a compliant electronic A&D book.
6. The 4473 Chain Break
The disposition entry, the Form 4473, and the NICS documentation form one chain for every retail sale. Investigators sample it constantly: pick a serial number, follow it to the disposition, pull the 4473, check the background check documentation. A missing 4473, an unrecorded NICS transaction number, or a disposition that references the wrong buyer breaks the chain and generates findings on multiple line items at once, which is how a single sloppy transaction becomes four citations.
What a Clean Process Has in Common
- The record is a side effect of the transaction. Receiving a gun creates the acquisition. Ringing the sale creates the disposition. Nothing depends on someone remembering a second step.
- Serial numbers are captured once, verified, and reused. Every downstream record inherits the verified number instead of re-typing it.
- Corrections leave a trail. The original entry survives every edit.
- Reconciliation is scheduled, not aspirational. The book is compared against physical inventory on a calendar, and discrepancies are chased the week they appear.
This is the practical difference between standalone compliance software and a system where the point of sale and the A&D book are the same system. When they are separate, every transaction requires the same data to be entered twice, and every double entry is a chance for the two systems to disagree. When they are one system, the reconciliation problem largely disappears.
