Every bulk order eventually has a dispute. The buyers who survive them are not the ones who avoid bad units — they are the ones who negotiated the return terms in writing and know how to document a claim. Here is how the process actually works.
DOA — dead on arrival — sounds self-explanatory, but in wholesale it needs a written definition or it becomes the source of every dispute. At minimum, a workable DOA definition covers three things: what counts (a unit that will not power on, will not charge, or fails a core function out of the box), when the clock starts (on delivery, not on shipment), and how it is proven (a video of the unboxing and test, serial or IMEI visible).
Without that definition, "DOA" means whatever the two parties can argue it means. A supplier who has not defined DOA in writing has not really offered DOA coverage at all — they have offered a negotiation that starts the moment a claim arrives.
The single highest-leverage moment in a bulk purchase is before you send money, and the return policy is the most important thing to lock down in that window. Ask directly, in writing: what is the DOA window, what is the functional return window, what documentation is required, who pays return shipping, and whether the resolution is a credit, a replacement, or a refund.
A supplier with a time-bound, written dispute process is worth more than a slightly lower quote. A low price with no return terms means the margin you "saved" is at risk the moment a shipment arrives with even a small failure rate. Treat the return policy as part of the unit price, because functionally it is.
Most DOA and return claims fail not because the unit was fine, but because the claim was weak. A claim that gets approved follows a consistent evidence pattern:

Return terms in pre-owned iPhone wholesale vary widely, but a few norms are worth knowing as a benchmark. A standard DOA window is short — often 3 to 7 days from delivery — because the supplier cannot see what happened to the unit after that. A separate functional return window, covering defects that appear after the unit is sold, is typically longer, in the range of 14 to 30 days. Beyond that, coverage is usually negotiable and scales with order volume.
Three terms matter more than the length of the window: who pays return freight, whether the resolution is credit or refund, and whether a returned unit can be inspected by the supplier before the claim is honored. A credit against your next order is far more common in wholesale than a cash refund, so plan your cash flow around that reality.
A returns process only works if it is run before a dispute happens. Pre-assign who receives the shipment, who tests the returned units, and how the findings get written up. Keep a running log of every claim, its status, and its resolution, so a supplier cannot quietly let a claim age out. And when you find a supplier whose DOA and return terms hold up in practice, that track record is worth more than a point of margin — it is the difference between a supplier and a liability.
