Enterprise fulfillment for Shopify Plus
Shopify Plus brands hit walls regular 3PLs were never built for — expansion stores, Flow automations, B2B channels, six-figure-launch days. We work with Plus merchants who need a fulfillment partner that handles multi-store inventory, custom checkout flows, and traffic spikes without scrambling. Same-day shipping from Paramount, CA across every store you run.
What syncs automatically
Multi-store, B2B, and high-volume Shopify Plus orders fulfilled out of one Paramount, CA warehouse.
Orders
Orders from every Shopify Plus store and expansion locale flow into our WMS through a single connection.
Inventory
One inventory pool, allocated across stores and locations by your rules — not by guesswork.
Tracking
Tracking writes back per store so each storefront triggers its own branded shipping notifications.
Returns
Returns reconcile against the originating store so refunds, exchanges, and restock decisions stay clean.
Why brands using Shopify Plus choose 3PLGuys
Multi-store and expansion store ready
Run a US store, a UK expansion store, and a B2B store off the same inventory. We allocate per store with rules you set, not workarounds.
Shopify Flow friendly
Your Flow automations stay intact. Tags, fraud holds, VIP routing, and gift-with-purchase logic all pass through to our pick path.
B2B channel support
Plus B2B orders, draft orders, company-level pricing, and net-terms shipments fulfilled alongside DTC out of the same warehouse.
Launch-day surge capacity
Influencer drops and product launches that 10x your daily volume don't break our SLA. Same-day cutoffs hold through the spike.
Custom packaging at scale
Branded mailers, inserts, tissue, stickers, gift notes — kitted and pulled per SKU or per order tag. We honor your unboxing without slowing pick time.
Plus checkout extensibility intact
Custom checkout apps, Shop Pay installments, post-purchase upsells, and Shopify Markets all play nicely with our order ingestion.
How the integration works
Connect your Shopify Plus account and ship within days, not months.
Connect every store
Hook up your primary Plus store, expansion stores, and B2B store through API. We map them to inventory pools and routing rules on day one.
Receive and SKU-map inventory
Send inventory to Paramount. We receive, count, and slot it, then mirror SKU-level availability back to every store you've connected.
Ship at Plus volume
Orders flow in across stores. We pick, pack, and ship same-day with carrier rate shopping. Tracking and stock sync back to each store automatically.
Built for Shopify Plus sellers
Brands graduating from Shopify to Plus
You crossed the volume threshold, signed the Plus contract, and now you need a 3PL that can keep up with what Plus unlocks — expansion stores, B2B, Flow logic, and bigger launches.
Multi-region merchants
US, Canada, UK, AU stores fed from one warehouse where it makes sense, with regional carriers and duty-handled labels where it doesn't.
DTC + B2B under one roof
Your DTC store ships parcels, your B2B store ships pallets to retailers. Same SKUs, same building, different workflows, no duplicate inventory.
Influencer and creator-led brands
Big-name drops, podcast mentions, viral TikToks. We've seen the spikes and we don't blink at them.
