1. Export your lot data
Before you give notice, pull on-hand quantity by SKU, lot number and expiration date from the current warehouse. This is the record you will reconcile against.
Switching Supplement 3PLs
Move your inventory, keep your lot history, and do not miss a renewal cycle.
When It Is Time to Move
Supplement brands usually outgrow a warehouse the same way: short-dated product reaches customers, counts stop matching, and nobody answers when something goes wrong.
Short-dated product reaches customers
The warehouse is picking whichever unit is closest, not the one that expires first.Nobody can tell you which lot shipped where
If a recall happened tomorrow, you would have to pull every unit of the SKU.Counts drift
Inventory discrepancies have become routine and you oversell during promotions.Bundles and free gifts ship wrong
A promotion that should lift revenue produces refunds and support tickets instead.Silence during a problem
OC3PL acknowledges all client requests within two hours and assigns a dedicated account manager from day one.
The signs:
The Move, in Order
Most clients go live within five to ten business days, depending on complexity.
2. Connect the store
We set up the integration, map the catalog and run test orders before any inventory moves.
3. Send inventory in waves
Ship the bulk first and keep enough at the old warehouse to cover orders in transit. Each inbound is received within one business day when it arrives labeled and scheduled.
4. Reconcile at receiving
We record lot and expiration on every inbound and photograph each SKU. Anything that does not match your advance shipping notice is flagged in your portal.
5. Turn on daily orders first
Start with everyday direct-to-consumer orders and watch them closely before the first subscription cycle or promotion runs.
6. Then the first big cycle
For a subscription run or a sale, send a volume forecast at least a week ahead, with written bundle instructions and photos, so labor is scheduled.
Common Questions
Most clients go live with OC3PL within five to ten business days, depending on complexity. Onboarding covers integration setup, SKU slotting and product mapping, and your first inbound shipment. Progress sits in a shared milestone tracker.
Not if you export it first. Pull on-hand quantity by SKU, lot number and expiration date from your current warehouse before the move. We capture lot number and expiration date again at receiving, so the two records can be reconciled.
Move inventory in waves and keep enough at the old warehouse to cover orders while freight is in transit. Inbound shipments that arrive labeled and scheduled are received within one business day, so the gap is the transit time, not the receiving time.
Do not make the first renewal cycle the first test. Turn daily orders on first and watch them closely, hold a short daily call with your account manager, then run the cycle with a volume forecast delivered at least a week ahead.
No. OC3PL integrates with the ecommerce, shipping and subscription tools most brands already use, including Shopify, WooCommerce, BigCommerce and Amazon. If a platform is not on the list, the in-house team builds the connection.
