One package identifier. Our order lists the arm, controller, and the controller power lead. I've checked all the foam compartments. Neither missing item is hiding underneath.

Send that inventory with photos of the crate label. Ask the seller to assign the controller and the controller power lead to a package number and provide its transport reference

Is this a contents shortage or an undelivered parcel? I can't find their split-shipment explanation in our order documents.

Call it the undelivered balance of your order for now. Your inventory is clear even if their packing arrangement isn't.

Exactly. With only one package on the note, the controller wasn't in that shipment. Ask for the other consignment details

One recorded package. That's all the note establishes. It doesn't tell us what belonged inside, or prove another shipment exists.

You're right about that inference. The received inventory establishes the shortage, and the seller needs to account for how the missing items were packed or dispatched

@FarahArcher0417 Can any setup preparation happen with just the arm there?

Paperwork and visible label checks, yes. Keep the arm off, and don't try another controller just because it looks similar

@YasminAdams0093 I haven't powered it and won't. The gap on our bench is frustrating; I wasn't planning to borrow a controller to fill it.

My separate equipment delivery had a contents list for each box. It made tracing the missing box much easier than reciting the complete order every time.

Were those identifiers from your seller or carrier? I can imagine ending up with another pair of lists that don't match.

@FarahArcher0417 Use both sets where needed, but ask the seller to map its package identifiers to the carrier references. Don't assume similar numbers are the same box.

@FarahArcher0417 In your records, give the delivered arm its own received status. Keep the controller and accessory outstanding rather than applying one delivery scan to everything.

I've received the missing controller and the controller power lead and checked their identities against the order. That closes the delivery shortage, with commissioning still to do.

That closes the inventory gap. Having the right items in hand gives you a basis for the commissioning checks
