Four weeks out
Confirm production dates, size curve and packaging.

A countdown from production to launch day, so the drop goes out as well as it sells.
Most drop problems start weeks before launch.
A normal day spreads orders across the hours. A drop puts most of them in the first one.
The drop model works because scarcity and timing create demand. The same features make it hard to fulfill. Everything has to be in the building, counted and ready before the link goes live, and then a large share of the orders arrive almost at once. There is no time to fix a miscount or find missing mailers after the fact.
Customers who waited for a release also expect it to ship quickly. A sold-out drop that ships late turns hype into support tickets. Planning is what keeps the excitement on social media rather than in your inbox. Read the streetwear drop model, explained for the background.
If this is an early drop and you have little sales history, how much inventory to order for a first production run covers how to size it.
The advance shipping notice is the single most useful document in this phase. If you are not sure what goes in one, see what is an ASN.
At OC3PL, labeled inbound is received and slotted within one business day, and most kitting builds are completed within 24 to 48 hours. That is why we ask for inventory and a forecast at least a week ahead.
On launch day, watch inventory in real time and keep in touch with your account manager. If the drop sells faster than forecast, the warehouse can adjust labor while orders are still coming in. Your account manager works on site at our Anaheim fulfillment center, in the same building as your inventory. When something is urgent you call and talk to a person who can walk to the shelf and fix it. Call anytime. We are here. We got you.
After the drop, the work shifts to exchanges and returns. Customers who guessed the wrong size will want the right one quickly, and with limited stock, every returned item may be someone else’s exchange. Returns are processed and logged within 48 hours of receipt, and many are handled the same day. Each item is inspected and restocked, discarded or donated by the rules you set.

Most failed drops are not caused by demand. They are caused by small operational gaps that become large at volume.
Each one is avoidable with the countdown above. If you sell through multiple channels, also read bots, cancellations and order holds around a drop.

The drop date and time, expected order count, styles and sizes, any bundles or gifts with purchase, packing instructions with photos, and your packaging materials.
If you can, yes. Building kits ahead means launch day is only picking and shipping. OC3PL supports kitting to stock ahead of time or to order.
Call your warehouse contact right away. A team on site can move labor while the drop is live. Agree in advance how oversells will be handled.
Process returns quickly so returned sizes can fill exchanges. Decide your policy for sold-out sizes before launch.
