The short answer
Allocation is the rationing of product that is scarcer upstream than downstream demand. A distributor allocates against criteria including purchase history, preorder participation, account standing and geographic distribution — and no criterion creates product that does not exist.
Allocation is not something distributors invented to be difficult. It starts at the manufacturer, where production on a given product is finite and demand from distribution exceeds it. Each distributor receives a quantity, and that quantity is itself an allocation decided by criteria the distributor does not control and often is not told.
The distributor then faces the same arithmetic one level down: more dealer demand than product. Every distributor in the industry resolves this somehow. The difference between them is whether the method is written down.
This matters because the most common frustration a shop expresses — "I placed my order first and still did not get it" — reflects a reasonable assumption that does not hold. Allocation is almost never first-come-first-served, because a queue would reward whoever refreshes a page fastest rather than whoever will actually sell the product.
A distributor allocating scarce product is trying to answer one question: which distribution of this quantity best serves the network, the supplier and the business. That resolves into a handful of factors that appear, in some form, at most serious distributors.
Most of what determines allocation is either outside your control or accumulates slowly. Four things are genuinely within reach, and shops that do them consistently get treated differently within twelve months.
First, indicate interest early and specifically. Aggregate dealer demand is what a distributor carries upstream when it argues for volume, and a named account requesting a stated quantity is a materially stronger argument than a general request for allocation. An account that never indicates is invisible in that number — which is precisely why participation is usually one of the criteria.
Second, buy across the calendar. Purchase history that spans the products nobody fought over is worth more in an allocation decision than a larger number concentrated entirely on flagship releases.
Third, pay on the agreed terms without exception. Payment history is one of the few criteria that can move quickly in the wrong direction, and it moves slowly in the right one.
Fourth, do not cancel confirmed allocations. A cancelled allocation is product that could have gone to an account that would have sold it, and distributors remember. If you are unsure you can take a quantity, request less.
Many distributors describe account tiers, and some publish them. A tier is a description of an account’s history — volume, tenure, breadth, payment record — and it is a useful shorthand for both parties.
What a tier cannot be is a guarantee. No distributor can promise that reaching a tier produces a specific allocation, because the distributor’s own supply is not guaranteed. When a tier is presented as an entitlement, it is describing something outside the promiser’s control, and the first time a release comes in short the promise breaks.
The honest formulation is that a tier reflects the history that allocation criteria weight. That is genuinely valuable and it is not the same as a claim on inventory.
Ask. A distributor operating on documented criteria should be able to explain a decision that affected your account — not disclose what other accounts received, which is confidential, but tell you which factors weighed against you and what would change the answer next time.
If the explanation is "that is just how it came in", you have learned something useful about the relationship. If the explanation is specific — you did not indicate interest, your purchase history in the category is thin, the supplier restricted the release geographically — you have learned something actionable.
The reason to publish allocation criteria at all is that it makes this conversation possible. A written basis turns an allocation decision from something that happens to you into something you can work with.
Because a queue rewards whoever refreshes fastest rather than whoever will sell the product. Distributors allocate against criteria — purchase history, preorder participation, account standing, geographic distribution — because those better predict where product will actually reach a retail floor.
Sometimes, and not as a matter of course. Purchase history is one of the criteria and a new account has none — a statement about sequence, not worth. The accounts that build a position fastest indicate interest consistently and buy across the calendar rather than only on the products everyone wants.
No, and any distributor implying otherwise is promising something outside its control. A tier reflects the history that allocation criteria weight. Supply upstream is not guaranteed, so downstream allocation cannot be either.
