Map the calendar
Drops, launches, promotions and peak for the next six months.

The right time to move is rarely the moment you decide to. Here is how to pick the window.
Most apparel brands decide to switch warehouses in the middle of a bad week: a drop that shipped late, a peak season that went wrong, a problem nobody answered. That is the right time to decide, and usually the wrong time to move. The move itself should land in a quiet window.
One bad day is not a reason to move. A pattern is.
| Sign | What it usually means |
|---|---|
| Wrong sizes and colors ship regularly | Mixed bins or picks that are not scanned |
| Drops ship days late | No labor planning for launches |
| Returns sit for weeks | Returns are a low priority, and stock is stranded |
| Counts never match | Receiving is not checked against your ASN |
| Answers take days | Nobody you can reach is in the building |
| Invoices surprise you | Line items are not spelled out |
If several of these show up month after month, the warehouse is not set up for apparel at your volume. See signs your apparel brand has outgrown its 3PL.
Map your year first. The move goes in the gaps.
Every apparel brand has a calendar of drops, seasonal launches, promotions and peak. Lay it out for the next six months and look for a stretch of a few weeks with no big event.
| Period | Typical activity | Move here? |
|---|---|---|
| The weeks before a drop | Inbound arriving, bundles being built | No |
| The week of a drop and the two after | Order spike, then exchanges and returns | No |
| Late fall into the holidays | Black Friday, gifting, holiday cutoffs | No |
| January | Holiday returns and exchanges | Usually not |
| After returns settle, before spring launches | Quieter weeks for many brands | Often a good window |
| Between seasonal launches | Steady daily orders | Often a good window |
Surf and swim brands have their own calendar, with a summer peak. Their quiet window is often in the fall, before holiday gifting. Streetwear brands should plan around their own drop schedule rather than the season.
The cleanest moves happen when new production goes straight to the new warehouse. Instead of moving existing stock twice, you send the next container to us and move the remaining stock from the old warehouse in waves.
See receiving apparel from factories and imports through LA and Long Beach.
Check your current agreement before you set a date. Many warehouse contracts include a notice period, minimum terms or fees for removing inventory. Plan the move so those costs are known up front.
At OC3PL there are no order minimums and no long-term contract, so a future move would not be held back by one.
Most clients go live within five to ten business days, depending on complexity. Onboarding covers the store integration, SKU mapping and slotting, and your first inbound shipment, with a dedicated onboarding manager and progress in a shared milestone tracker.
| Step | What happens |
|---|---|
| Discovery call | Volume, SKU count, channels, calendar and what has been going wrong |
| Integration | Store connected, variants mapped, test orders run |
| First inbound | Received against your ASN, photographed and slotted |
| Go-live | Daily orders switch over and are watched closely |
| First big event | A drop or promotion, planned with a forecast |
See apparel 3PL onboarding for the step-by-step version.
Sometimes the current warehouse fails at the worst time and waiting is not an option.
If a warehouse is failing during peak or right before a drop, waiting for a quiet window may cost more than moving. In that case, move in a way that limits risk.
All client requests are acknowledged within two hours, and support is never outsourced.
A well-run move is invisible to customers. Two things help.
After the move, watch your support inbox for "where is my order" questions for a couple of weeks. A spike usually points to orders caught between the two warehouses.
A move costs time and attention. Make sure the reasons are worth it.
Before you start, write down what the current warehouse is costing you beyond its invoice. Apparel brands often find the hidden costs are larger than the fees.
| Hidden cost | Where to find it |
|---|---|
| Mis-picks | Exchanges and refunds marked "wrong item" |
| Late shipments | Support tickets asking "where is my order" |
| Stranded returns | Units sitting in returns that are not in available stock |
| Oversells | Cancelled orders for sizes that showed in stock |
| Team time | Hours spent chasing the warehouse for answers |
| Lost drop sales | Orders cancelled after a slow launch |
Put rough numbers next to each. If they add up to more than the cost and effort of a move, the case is made.
Giving notice before the new warehouse is ready can leave you with nowhere to ship from. Line everything up first.
Every move is different. This is a common shape for an apparel brand doing a few thousand orders a month.
| When | What happens |
|---|---|
| Weeks before | Decide, choose the window, check your contract |
| Onboarding begins | Integration, variant mapping and test orders |
| First inbound | Next production or the first wave of stock received and slotted |
| Go-live | Daily orders switch over |
| After go-live | Remaining stock moved in waves; old warehouse wound down |
| A few weeks later | The first drop or promotion at the new warehouse |
Most clients go live within five to ten business days of onboarding starting, depending on complexity.
If you ship to retailers, tell them about the move ahead of time. Some retailers need updated ship-from details, vendor setup or new EDI connections.
Retail and wholesale clients typically go live in under seven business days once integration and purchase order sync are complete. See apparel wholesale and retail fulfillment.
| Mistake | What happens | Better approach |
|---|---|---|
| Moving the week before a drop | The drop runs on a warehouse that is still learning your catalog | Move after the drop, or well before it |
| Moving all stock at once | A gap where nothing can ship | Move in waves, keeping cover stock behind |
| No inventory export before notice | No record to reconcile against | Export by SKU, size and color first |
| Forgetting the return address | Returns arrive at the old warehouse | Update your store and returns app on go-live |
| Choosing on rate alone | The same problems at a new address | Compare complete quotes and who answers the phone |
See the apparel 3PL checklist for the questions to ask before you choose.
Some brands switch not because the warehouse failed, but because they are about to outgrow it: a big retail account, a new marketplace, a jump in drop volume. In that case, move before the growth arrives, not during it.
One apparel brand on our results page grew from 500 to 5,000 orders a day over two years and moved into big-box retail without changing warehouses. Growth like that is easier to absorb in a warehouse set up for it from the start.
If a large retail order or a major launch is on the calendar, plan the move so you are live and settled at least a few weeks ahead of it.
By the time your first drop runs, the team knows your catalog, your packing and your customers.

Four steps to timing a move.
Drops, launches, promotions and peak for the next six months.
A few weeks with no big event.
Route the next container to the new warehouse.
Daily orders first, the first drop after.
In your quietest weeks, away from drops, big promotions and peak season. For many brands that is after holiday returns settle, or between seasonal launches.
Only if the move can be finished well before your first holiday promotion. Moving in the weeks just before peak is risky.
Most clients go live within five to ten business days, depending on complexity.
Yes, where possible. Routing your next inbound straight to the new warehouse avoids moving that stock twice.
Move your best sellers first and keep slow sellers in place until the busy period passes. Talk to your new account manager daily.
Update your return address as soon as the new warehouse is live, and have the old warehouse forward anything that still arrives.
No. There are no order minimums and no long-term contract.
Not as the very first thing. Let daily orders run cleanly first, then plan the first drop with a forecast.
The notice period, any fees for removing inventory, any monthly minimum during notice, and who owns packaging stored there.
A dedicated onboarding manager and your account manager, who works on site in Anaheim.
Yes, ahead of time. Some retailers need updated ship-from details or EDI setup before the first shipment from the new warehouse.
No. Line up onboarding, your inventory export and your next inbound first, then give notice under your current contract.
Yes. Many brands move best sellers first and slower styles later, in waves.
Yes. Your account manager works on site in Anaheim, and we are glad to walk you through how apparel is slotted, packed and returned.
Yes. Share your drop, launch and promotion calendar and we will suggest a window that keeps the move away from your busiest weeks.
