Average items per order
Overall, and during drops and promotions.

A customer who buys an outfit is your best customer. Make sure the order is priced, packed and shipped like it.
Apparel customers often buy more than one item: a tee and a hoodie, two sizes to try, a full outfit, a bundle. Each extra item adds a pick and packing work, and usually lowers the shipping cost per unit. Knowing your average items per order is one of the most useful numbers in an apparel business.
Most quotes split the work into two parts.
The pick and pack fee covers the labor and technology to collect items, choose the right package, pack, seal and label. Most quotes split it into a per-order fee, for the work every order needs, and a per-item fee, for each additional unit. Packaging materials are often billed separately, so confirm what your quote includes.
| Order | Order-level work | Item-level work | Shipping |
|---|---|---|---|
| One tee | One order handled, one label | One pick | One small package |
| Tee and hoodie | One order handled, one label | Two picks | One larger package; lower shipping per unit |
| Four-piece outfit | One order handled, one label | Four picks | One box; lowest shipping per unit |
| Pre-built bundle | One order handled, one label | One pick of a finished kit, plus the kitting work done ahead | Depends on the kit’s packaging |
The pattern: order-level costs are shared across more items, item-level costs grow with each item, and shipping per unit usually falls. Ask your 3PL to show you this on a sample invoice using your own order mix. See pick and pack fees explained.
The only reliable way to see the real numbers is line-item billing. Add every fulfillment charge for a period and divide by orders shipped to get a fully loaded cost per order. See apparel cost per order.
More items means more chances to get the presentation wrong. Write packing instructions that cover multi-item orders: the order items go in, how each is folded, whether items share a bag, and which mailer or box size fits which item count.
Right-size the package. A mailer that fits two items costs less to ship than a box with air in it, and carriers can charge by size as well as weight. See poly mailer or box and dimensional weight.
A multi-item order is only right if every item is right. Every style is slotted by size and color, so a picker reaching for a medium in black is not digging through a bin of mixed sizes. A new collection is slotted and ready to ship within one business day of receipt. Every unit is scanned before it is packed, which catches a size mix-up before it reaches the customer.
If a size is short when the order is picked, agree in advance what happens: hold the order, ship what is available and send the rest later, or contact the customer. Write the rule down with your account manager. All client requests are acknowledged within two hours, and support is never outsourced.
Buy-more-save-more offers, bundles and gifts with purchase all raise items per order. That is usually good for margin on shipping and bad for packing time, so plan for it. Tell your account manager before the promotion starts, with the offer, the expected order volume and any gift items, so labor and packaging are ready.
Pull these from your store and your invoices.
Overall, and during drops and promotions.
How many orders ship in each mailer or box size.
Every fulfillment charge divided by orders shipped.
Orders with two sizes of one style tell you about fit.
Most pick and pack quotes split into a per-order fee and a per-item fee, so each extra item adds an item-level charge. Packaging materials are often billed separately, so confirm what your quote includes.
Usually, because several items share one package and one label. Right-sized packaging matters, because carriers can charge by size as well as weight.
Yes. Kitting can be done to stock ahead of a drop or to order as orders come in, and most builds are completed within 24 to 48 hours.
Agree the rule in advance with your account manager: hold the order, ship what is available, or contact the customer.
Add every fulfillment charge for a period, including receiving, storage, pick and pack, packaging, shipping and returns, then divide by orders shipped.
Usually, because it is an extra unit to pick and pack. Ask for it to be shown as its own line, and decide whether the promotion still pays at your margin.
