How long is the QC window and can it be extended?
The standard window is measured in days rather than weeks, and extension is available at some warehouses as a paid holding service rather than as a standard option.
The evidence
The window length is a published policy rather than a fixed industry number, and it varies by warehouse. What is consistent is the unit: days. That makes the window short relative to how long a buyer may take to inspect a photo set properly, which is why the practical advice is to open the folder on the day the notification arrives rather than at the weekend.
Extension exists at some warehouses as a holding service. Where it is offered, it is charged per day beyond the standard window, and the charge is usually small in absolute terms. Whether it is worth paying depends on what you are uncertain about: for a parcel containing a single item you are confident in, extension buys nothing; for a mixed parcel with one item you are unsure about, extension buys the time to resolve that item without a return.
There is an important detail about how the window interacts with the shipping payment. The window governs approval of the items, not the timing of the shipping payment. A buyer who extends the window is still able to pay for shipping afterwards, and the storage clock starts from the warehouse intake rather than from the approval. That ordering matters when storage charges are a concern.
When this does not apply
Where the warehouse has not yet completed intake on all items in the order, the window for the whole order is governed by the last item to arrive rather than the first. Checking whether every item has been photographed before starting the review prevents a partial review that misses the item you were worried about.
