The sealed accessory box contains 73 adapters for the 80 matched fixture kits we ordered. Everything else matches the per-kit list. Seller now says 80 meant pieces, although the invoice says kits and its final confirmation lists one adapter in each. I have put that confirmation beside receiving's count and asked for the seven missing adapters, not a new explanation of what a kit might mean.
Keep the invoice, final agreed contents and receiving count together, and ask their order contact to reconcile the seven-adapter shortage against that accepted list rather than debating a generic definition of kit.
Order contact acknowledged the per-kit confirmation and corrected the quantity explanation. They say the packing team counted adapters incorrectly. I asked for the missing seven under the same assembly reference and their supply arrangement.
They confirmed the same adapter reference and sent a packing list for seven. Parcel has a carrier acceptance scan. Receiving has that separate list; shortage stays open until the adapters arrive and are checked.
That resolves the counting dispute without closing the physical shortage, and the separate receiving list should keep the seven from being mistaken for another complete accessory order.
