How do I set up a delivery appointment at a distribution centre?

Distribution centres run their dock doors on a schedule, and freight that isn’t on that schedule usually doesn’t get unloaded. If you’re shipping into a DC for the first time — filling a purchase order as a vendor, or moving stock into a customer’s network — the delivery appointment is the detail that decides whether your truck is received or sent away.

The good news is that the process is the same almost everywhere, even though every facility has its own system. Here’s how appointment booking works, what receiving will ask for, and how to keep the whole thing from becoming a source of missed deliveries.

Why distribution centres require appointments

DCs require appointments because they receive a high volume of trucks against a fixed number of dock doors and a planned labour schedule. Receiving managers assign doors, unloading crews and put-away work hours or days in advance — an unscheduled truck has no door, no crew and no slot in the plan, which is why “just showing up” so often ends with the driver being turned around.

Appointments also protect the freight itself. When a delivery is expected, the receiving team has the purchase order pulled up, knows the pallet count, and can check the shipment in properly. For the shipper, that translates into a clean proof of delivery instead of a disputed one.

Who books the appointment

Whoever the DC’s routing instructions name is the party that books — and getting this wrong is the most common first-timer mistake. There are two common patterns:

• The carrier books. The DC wants scheduling requests to come from the delivering carrier, since the carrier controls when the truck is actually available. The shipper hands the carrier the PO number and shipment details, and the carrier requests the slot.
• The vendor books. The DC runs a supplier portal where the vendor requests the appointment against the purchase order, then passes the confirmation number and window to the carrier to execute.

If you ship through a courier or freight provider regularly, tell them which pattern your consignee uses when you book. A carrier that handles DC deliveries routinely — as part of next-day LTL service, for example — can take over the scheduling call once it knows where the freight is going.

What receiving will ask for

Every scheduling system asks for roughly the same shipment profile, so have it ready before you request the slot:

• Purchase order number(s) — the anchor for the whole appointment; most DCs won’t book without it
• Carrier name and, sometimes, the driver or truck details closer to the date
• Piece count — number of pallets or cartons, and whether the freight is palletized or floor-loaded
• Total weight of the shipment
• Bill of lading or reference number tying the paperwork to the booking
• Requested date, plus any constraint on your side (freight not ready until a certain day, for instance)

Accuracy matters more than speed here. If the appointment says four skids and six show up, the DC is within its rights to receive four and refuse two — the appointment is a commitment to a specific shipment, not just a time.

How delivery day plays out

On the day, the driver arrives within the window, checks in, and follows the facility’s process. A typical sequence looks like this:

1. The driver checks in at the gate or shipping office with the appointment confirmation and paperwork.
2. Receiving assigns a dock door, and the truck backs in when called.
3. The freight is unloaded — at some facilities by DC staff, at others with the driver assisting; the appointment confirmation usually says which.
4. Receiving counts and inspects the freight against the PO, then signs the delivery paperwork, which becomes the proof of delivery.

Waiting is part of DC life even with an appointment — doors run behind, and trucks queue. That’s worth understanding before you book, because extended time at a stop can become a detention or wait-time charge depending on the carrier’s terms. An accurate appointment and complete paperwork are the best protection against it.

If the appointment is missed

A missed appointment gets rescheduled — the question is how painfully. Some DCs will work a late truck in the same day if a door frees up; others push the delivery to the next available slot, which can be days out at a busy facility. For vendors shipping against retail purchase orders, missed windows can also count against delivery-performance scorecards, which is a supplier-relationship problem, not just a freight problem.

The practical defences are unglamorous: book the appointment early, quote the confirmation number on every document, make sure the freight is actually ready before the pickup, and use a carrier that treats the window as a hard commitment. Our guide to dock scheduling and receiving practices covers the receiving side of this in more depth, and if you’re shipping into a customer’s DC under their rules, their supplier shipping instructions are the document to read first.

Appointments on recurring DC lanes

If you deliver into the same distribution centre every week, the appointment process stops being an event and becomes a rhythm — same portal, same profile, same windows. This is where a regional carrier that knows the lane earns its keep: the scheduling contact, the facility’s check-in quirks and the realistic transit time are already known, so each booking is a confirmation rather than a research project.

Sonic Transport moves B2B freight into distribution centres across the GTA, Golden Horseshoe and Southern Ontario, with appointment coordination handled as part of the run and a POD closing out every delivery. If you have DC freight to move — one appointment or a standing weekly lane — tell us about the shipment and a real person will sort out the schedule with you.
