Cross-docking means receiving goods and shipping them out again almost without their touching the shelf: they come in through one dock and leave through another, sometimes the same day.
What cross-docking is
In a normal warehouse the goods go through five steps: they are received, put away, stored, picked and dispatched. In cross-docking the three in the middle are removed. What arrives already has a destination (an order, a store, a route) and only stops in a sorting area for just long enough to be split up.
That is where the name comes from: “crossing the dock”. It is not a special facility but a way of working, and it can be applied to everything that comes in or only to part of it.
Types of cross-docking
| Type | How it works | Example |
|---|---|---|
| Direct (pre-distributed) | The supplier already sends each parcel prepared and labeled for its destination. At the dock it is only checked and moved to the outbound truck | Full pallets for a specific store |
| Indirect (consolidated) | Goods arrive unsplit. They are opened, separated by order or by destination and put together again | A pallet of one item that is split among several orders |
| Opportunistic | It was not planned: on receipt it turns out there is an order waiting for that product and it is sent straight to it | The replenishment of a sold-out item arrives with orders pending |
The third is the one that happens most in online store warehouses, and the easiest to start doing.
When it makes sense
- →When goods arrive that already have an order waiting.
- →In distribution to stores: a large pallet is split into smaller orders.
- →With products that should not be stored (fresh, urgent).
- →With launches or pre-orders: product sold before it arrives.
- →When the warehouse is short of bins and every pallet that is not put away is a relief.
When it does not pay off
- →If you do not know what is going to arrive or when: without inbound notice there is nothing to match it against.
- →If the supplier often ships short or late: the order that depended on that delivery is left hanging.
- →If the goods need a quality check before they can be sold.
- →If there is no space next to the docks to sort without getting in the way of normal inbound and outbound.
- →If the orders also carry other items that have to be picked from the shelf and nobody coordinates everything reaching the same table.
What it takes
- →Knowing what is coming before it arrives (inbound notice).
- →Software that matches what comes in against pending orders.
- →Space in the dock area for sorting.
- →Parcels identified with a label, so it is known which order or destination each one goes to.
- →Schedules: the departure planned for after the arrival, with margin for sorting.
- →Recording the movement all the same: even if it is not stored, it has to be on record.
How it is done step by step
1. The notice arrives. The supplier or the client says what they are sending and when.
2. It is matched against the orders. Before or at the moment of receiving, you look at which part of that delivery already has a pending order.
3. It is received and counted. Just like any inbound delivery: scanning and comparing with what was expected. It is the only checkpoint, so it is not skipped.
4. It is separated. What has an order goes to the sorting area or the packing table; the rest is put away as usual.
5. The outbound is prepared. The order is completed if it carries more items, it is labeled and left at the dock for its carrier or its route.
6. It is recorded. The inbound delivery, the direct move to the order and the outbound, with their quantities.
Common mistakes
- →Doing it from memory and losing track of what went across the dock.
- →Not noting the differences between what was expected and what was received.
- →Not counting on receipt “because it is leaving right away”: if something was missing, it can no longer be claimed.
- →Leaving the goods in the sorting area “until tomorrow”. If they stay, they have to be put away and recorded; otherwise it is stock nobody can find.
- →Sending a lot to the order without looking at the expiry date. The outbound rules apply just the same; they are in FIFO, FEFO and LIFO.
In Ubika, on receipt, goods that have an order waiting can go straight to that order, and it is recorded on the inbound delivery's record. If you ship for online stores, see also WMS for e-commerce; and if what squeezes you is the high-volume days, how to get your warehouse ready for peak season.
