Why you can't see your own customers
In most of the United States, the bar that pours your beer is not your customer. Your customer is the distributor. You invoice the distributor; the distributor invoices the account. That one structural fact explains most of what feels odd about the data that comes back to you — why it arrives second-hand, why it stops at the account door, and why there is so rarely a person's name attached to an account.
What follows is a general description of a common arrangement, not legal advice. Alcohol is regulated state by state, and the details differ enough that two neighboring states can run on genuinely different rules. But the broad shape holds nearly everywhere — and the shape of the rules turns out to be the shape of your reporting.
The three tiers, briefly
After Prohibition ended, most states rebuilt the alcohol trade as three separated layers and wrote tied-house rules to keep them apart, so that no single party could own the chain from production to pour. Whatever you think of it as policy, it is the ground you sell on.
In most states a supplier cannot sell directly into tier three. There are well-known exceptions: small producers with self-distribution privileges up to a volume cap, a producer's own taproom or tasting room, and direct-shipping regimes that in some states cover wine far more broadly than beer. Franchise statutes in many states also govern the supplier–distributor appointment itself, sometimes making it much harder to end than to begin. Which of those apply to you depends entirely on where you are.
You don't own the transaction
The practical consequence is simple. The transaction of record is supplier to distributor. A case leaves your warehouse against a distributor's purchase order, and everything that happens after that — which account took it, how many, which SKU, in what week — happens on somebody else's books. A depletion report is the middle tier telling you, after the fact, what left their warehouse and where it went.
That is why the word is depletion. It is inventory depleting out of tier two, not a sale you made. It also means you effectively keep two customer lists that people talk about as if they were one: the distributors you actually sell to, and the accounts you are sold into. You have a contract with the first list. You have a reported record of the second.
What arrives, and what doesn't
Once you accept that the account relationship is reported to you rather than owned by you, the contents of the file stop being surprising.
There is one more thing the structure does to you, and it is easy to miss. The distributor's own rep may be inside that account every week while yours gets there quarterly. Some of what you know about tier three is really what tier two knows about tier three. That is a constraint, and it is also the reason a distributor relationship is worth every bit as much as an account relationship.
Which is why the file is worth reading carefully
None of this makes the reporting less valuable. It makes it more so. For most suppliers, the depletion feed is the only systematic view of tier three they will ever have — the single place where thousands of accounts they cannot sell to directly show up in one list. It deserves better than a skim.
It is worth knowing what that reading turns up. We ran the comparison across one importer's own exports — roughly 30,000 rows in a single file:
Those accounts were not hidden. They were simply not there, which is what a transaction file does with a non-transaction. Nobody had done anything wrong. Lining up export after export side by side is a day's work that never reaches the top of anyone's Monday.
Or have it read every night
Sightglass reads the VIP depletion feed you already pay for and keeps every snapshot, so your history outlives any single export window. It looks for accounts going quiet and accounts that are winning, and hands each rep a short ranked list — in Slack, in an email digest, or on the dashboard — with the outreach drafted both to the account and to the distributor. Nothing sends without a person approving it, and approved mail goes from the rep's own mailbox, so replies come back to them. Your reporting stays exactly where it is.
