Pre-Pack vs Singles

What is pre-pack vs singles?

Pre-pack vs singles describes the two fundamental packaging approaches used when shipping apparel from a brand or manufacturer to retail locations. In apparel merchandising, the choice between pre-packs and singles directly affects warehouse efficiency, allocation flexibility, and inventory accuracy at the store level.

A pre-pack is a carton containing a predetermined ratio of sizes — for example, a pack of 12 units in a 1-2-3-3-2-1 size curve (XS through XL). A singles order allows each unit to be picked individually, enabling exact size quantities per store.

How each approach works

Pre-packs are assembled at the factory or distribution center before shipment. A brand defines a standard size ratio — say 1S/2M/3L/2XL — and every carton ships with that fixed mix. Pre-packs reduce labor costs significantly because warehouse teams handle cartons rather than individual units.

Singles picking means each store order is fulfilled unit by unit. A store needing 5 Medium and 2 Large receives exactly that — no surplus sizes, no shortages in high-demand sizes.

The tradeoff

The core tension is cost vs precision:

• →Pre-packs are 30–50% cheaper to process but force stores to accept a fixed size ratio that may not match local demand. A store that sells predominantly Large receives the same Small and XS units as every other door.
• →Singles match inventory precisely to each store's size curve but require significantly more warehouse labor and processing time.

Why this matters for apparel brands

Most brands use a hybrid approach — pre-packs for initial seasonal allocation (when speed matters) and singles for replenishment and reorder (when precision matters). The key is ensuring the pre-pack ratio reflects actual demand rather than a generic assumption.
