Prepack Versus Case Pack: Which Works Best For Apparel?

Prepack

A pre-defined assortment of apparel sizes and quantities packed together for retail or wholesale distribution. Comparing prepacks to case packs helps brands choose the right packing strategy for distribution, merchandising, and cost.

Both prepacks and case packs are ways to group units for shipping, but they serve different operational needs. A prepack mixes sizes in a single pack; a case pack contains identical units (same size and color) in each carton. Understanding the trade-offs clarifies when to use one approach over the other.

Key Differences

• Size Composition: Prepacks contain multiple sizes; case packs contain only one size or variant per carton.
• Receiving Process: Prepacks are received as assortments and often counted as single line items; case packs require more line items when multiple sizes are ordered.
• Retail Readiness: Prepacks are typically store-ready assortments; case packs require breaking out cartons to assemble assortments on the sales floor.
• Flexibility: Case packs provide greater flexibility in distribution because sizes can be sent to different stores based on demand.

When To Use Prepacks

Choose prepacks when the retailer wants simplified receiving and quick merchandising, or when the distribution model favors sealed assortments — for example, big-box stores standardizing stock or suppliers sending bulk replenishment to DCs that will transfer assortments to stores. Prepacks reduce store labor and speed shelf restocking.

When To Use Case Packs

Case packs make sense for centralized distribution centers that perform pick-and-pack to create store-specific assortments, for e-commerce where single-size orders are common, or when demand varies significantly between locations. Case packs enable precision in allocation because inventory can be redistributed by size without opening mixed cartons.

Cost, Labor, And Inventory Impacts

• Packaging Cost: Case packs may be slightly cheaper per unit because cartons contain identical units and packing is simpler at volume.
• Labor: Prepacks reduce receiving and store labor; case packs increase packing flexibility but require more handling at the DC or store to build assortments.
• Inventory Visibility: Case packs preserve size-level inventory control inside sealed cartons; prepacks require systems that record size-break on receipt to maintain accuracy.

Retail Compliance And Chargebacks

Some retailers mandate a packing method. They may require prepacks for quick replenishment or allow case packs if the vendor provides accurate size-level ASN details. Non-compliance (wrong pack type, incorrect size-breaks, missing labels) commonly triggers chargebacks, so confirm retailer requirements in advance and document differences in EDI/POs.

Practical Decision Matrix

• Use Prepacks If: Your retailer prioritizes speed-to-shelf, you ship to many small store locations, or you want to reduce store-level handling and shrink risk.
• Use Case Packs If: You need allocation flexibility by size, you ship mostly to a central DC that will re-configure assortments, or e-commerce single-size demand is high.
• Hybrid Approach: Some suppliers ship case packs for DCs and prepacks directly to stores — common when selling into both omnichannel and brick-and-mortar channels.

Example Scenario

A brand supplying a national chain uses prepacks for direct-to-store shipments: each carton arrives with a ready assortment to replenish shelves. For wholesale accounts that receive at a central distribution center, the brand sends case packs so the retailer’s DC can build store-specific assortments, optimizing regional size demand.

In short, the Prepack offers speed and simplicity by shipping predefined size assortments, while case packs offer flexibility and tighter size-level control. Choose based on retailer requirements, your fulfillment model, and where you want the assortment decision — at the vendor, the DC, or the store.
