B2B and DTC Fulfillment From One Warehouse

Why hybrid brands end up with two warehouses

DTC takes off on Shopify. Wholesale orders start coming in from accounts like Faire, specialty retailers, or a national chain. The DTC 3PL doesn’t ship pallets, doesn’t do EDI, and can’t handle a routing guide. So a second warehouse gets bolted on for B2B. Now there’s split inventory, two receiving teams, two cycle counts, and two systems that disagree on what’s in stock.

The real cost of running split inventory

Stockouts on one channel while the other has surplus

Manual transfers between locations, plus the truck cost and the one to two week lag

Double the receiving labor and double the cycle counts

Compliance issues when retailer rules don’t match the DTC workflow

Customer service slowdowns when two systems disagree on stock

What "one warehouse, both channels" actually means

One physical inventory pool. DTC orders flow through Shopify or whichever sales channel you use. Wholesale orders come in through EDI or a retailer portal, get picked to the retailer’s spec, and ship on pallets with the right paperwork. Same SKU. Same shelf. Different downstream workflow.

The orders aren’t identical. They aren’t supposed to be. The point is the inventory is shared and the integrations route each order to the right pick path.

The integrations are the part most brands underestimate

A real hybrid 3PL needs to plug into:

Your DTC sales channels (Shopify, Amazon, eBay, others)

Your ERP or inventory tool

EDI and retailer portals for wholesale orders

Carrier APIs for parcel and freight

3PL Center has more than 100 integrations live in production across these systems. If a 3PL can’t show you the integrations in a demo, assume they can’t do them in production either.

Retailer compliance is where most B2B 3PLs fail

Retailers have specific rules. Carton labels, ASN timing, routing guides, packing slip placement, pallet patterns. Miss one and the chargeback hits before you see the next PO.

A 3PL doing both DTC and B2B needs people who have actually shipped to those accounts, not just a system that says it supports them.

How 3PL Center handles B2B and DTC from one roof

One inventory pool across California and New Jersey, near the ports

Same-day shipping for outbound orders received by 2pm local

Real-time container tracking from arrival through put-away

More than 100 integrations across sales channels, ERPs, and retailer systems

Kitting and assembly for retail-ready packaging in the same building

When hybrid fulfillment from one warehouse pays off

The math works once DTC is steady and at least one wholesale account is real. If wholesale is one-off pop-ups or sample drops, two warehouses might still be fine.

Once both channels have monthly volume, running two warehouses costs more than the convenience is worth. Inter-warehouse transfers, duplicate cycle counts, and split inventory eat the savings. Apparel brands see this fastest, since wholesale and DTC SKUs overlap heavily.

What to ask any 3PL before signing

Show me a live B2B order getting picked

Which retailers are your customers shipping to today?

What is your chargeback rate on retailer compliance?

How do you handle a DTC stockout caused by a B2B shipment going out last night?

Can I see your integration list and which ones are live versus on the roadmap?

Most brands that try to run two warehouses for B2B and DTC end up at one. The faster the channels are growing, the sooner that move makes sense. The hard part is finding a 3PL that actually does both at the same address, not just on paper.
