Backorder Fulfillment: Queue to Carrier.
On stockout, ecommerce lines sit in the order queue until replenishment posts in the WMS. Lines release automatically; pick and pack uses the same verification as in stock, then carrier handoff on your normal cadence (often within ~24 hours when the lane is clear).
Step 01
Backorder Queue & Eligibility
When inventory is out of stock, eligible ecommerce lines enter the order queue with a fixed sequence (for example FIFO). Your cart rules and WMS SKU data stay aligned so buyers see backorder versus cancel states.
Step 02
Replenishment Receipt & Available Inventory
Inbound stock is received and checked in at the 3PL. Available inventory updates in the WMS. That receipt event unlocks the next backorder fulfillment lines in queue. No ops spreadsheet to fire release.
Step 03
Release to Pick, Pack & Ship
Released lines join the same pick and pack services path as in stock orders: scan-based picks, pack verification, carrier selection by cutoff, tracking and order status back to your storefronts.
Backorder Fulfillment: Stockout to Sync.
01
Connect Channels & Inventory
Plug Shopify, WooCommerce, or your stack into Evobox. On hand, committed, and order status feed the WMS so ecommerce backorders and available inventory stay aligned across storefronts.
02
Set Backorder Management Rules
Define max hold time, queue logic, and alerts at onboarding. Those rules drive backorder fulfillment in the 3PL: no ops edits per SKU wave.
03
Stockout: Order Queue
On inventory out of stock, eligible lines enter the order queue in fixed sequence. Buyers see accurate backorder messaging instead of silent cancels.
04
Replenishment Lands & Posts
Inbound is received at the fulfillment center; the WMS updates available inventory. That event unlocks the next ecommerce backorders waiting in queue.
05
Fulfillment, Tracking & Sync
Released units run through pick and pack services, then carrier and tracking. Receipt and ship events push inventory and order status back to your OMS. Customer returns stay on returns management services, separate from the backorder queue.

Backorder Volume
Monthly ecommerce backorder count and how often SKUs go inventory out of stock so we right-size queue depth and labor.
Replenishment Cadence

Backorder Fulfillment FAQ
Backorder fulfillment is warehouse execution for ecommerce when a SKU is inventory out of stock: the line stays in a managed order queue until replenishment posts in the WMS, then it releases to pick and pack services. A 3PL runs that loop so you are not managing spreadsheets or one-off holds. Evobox delivers this as part of its 3PL fulfillment program with the same inventory accuracy bar as in stock units.
The backorder queue follows your rule set, typically FIFO by order time. When replenishment is checked in and available inventory covers the oldest lines, those ecommerce backorders release first so revenue clears in sequence and the queue stays predictable for ops.
After replenishment is received and checked in, eligible lines typically release the same business day under normal volume and carrier cutoffs. Release feeds standard 3PL fulfillment: pick, pack, and carrier handoff on your posted cadence without a manual trigger.
Yes. Backorder management includes a maximum hold window you define at onboarding. Orders past that limit flag for review or cancel per your policy so payment capture and customer messaging stay aligned with your risk rules.
Yes. Receipt and ship events post back to connected carts and marketplaces so on hand and committed quantities track the warehouse. That keeps listings and bundles aligned with physical stock as the order queue moves. Returns are handled separately through returns management services so receiving does not collide with backorder release.
