Fewer boxes. Better customer experience.

Consolidate orders headed to the same address into one shipment to protect margins and simplify fulfillment from checkout to doorstep.

Simplify fulfillment operations

Avoid manual errors. ShipStation API automates the logic within your existing OMS, creating a consistent, repeatable workflow across teams and fulfillment locations.

Order consolidation features built for real-world fulfillment

Use ShipStation APIs to consolidate parcel shipments based on rules you define in your order management system. Programmatically group eligible order items into a single shipment while maintaining control over delivery promises and service levels.

Combine multiple orders into one shipment

Programmatically group eligible sales orders that share a customer or destination. Your system evaluates address, timing, inventory availability, fulfillment location, and service levels—then creates consolidated shipments via the ShipStation API when it improves efficiency, or keeps orders separate when speed or inventory requires it.

Define flexible consolidation rules

Configure consolidation logic within your existing systems—such as time windows, order value thresholds, product exclusions, service levels, and warehouse eligibility. Once your business rules are set in your OMS, ShipStation APIs execute those decisions in real time as shipments are created.

Keep orders moving together across locations

Operating multiple warehouses or managing 3PLs? ShipStation evaluates inventory location, cutoff times, routing logic, and SLA requirements before consolidating—helping you avoid unnecessary split shipments while maintaining inventory accuracy and protecting delivery promises.

Centralize orders before consolidation begins

Unify order data from multiple carts, marketplaces, and systems into a single stream before items are grouped together—so every shipment is evaluated consistently across channels, inventory locations, and service levels. One source of truth. Smarter grouping decisions.

Order Consolidation FAQs

An order consolidation API identifies multiple orders going to the same customer or address and combines them into a single shipment. Instead of processing each order separately, your system creates one bundled delivery—reducing cost and simplifying fulfillment.

By reducing the number of labels, cartons, and pickups per customer. Fewer packages typically mean fewer surcharges, lower dimensional weight exposure, and reduced overall carrier spend.

Not when configured correctly. ShipStation applies your timing and service rules before consolidating. Orders are only grouped when they can ship together without missing delivery commitments or cutoff times.

The API evaluates inventory availability before merging orders. If items are split across locations or unavailable within your defined window, consolidation will not occur. This protects inventory integrity and prevents downstream fulfillment issues.
