In brief

Orderlines are the individual lines of a customer order, each describing one item with quantity and unit of measure. They form the operational basis for picking, packing, and shipping in the warehouse.

Key facts

What are orderlines?

An orderline – also referred to as an order position or order item – is a single line within a customer order. It contains at minimum one item, a quantity, and a unit of measure. An order with ten different items has ten corresponding orderlines. The orderline is the smallest plannable unit in order fulfillment: everything that happens in the warehouse – from picking and packing to shipping preparation – can be traced back to individual orderlines.

Order positions should be distinguished from sub-positions, which arise when an orderline must be split across multiple storage locations or batches, as well as from consolidation steps, where multiple orderlines from different orders are processed together.

Relevance in warehouse operations

The number of orderlines per order is one of the most important metrics for warehouse design. Few lines per order at high order volumes – typical in e-commerce – means short, fast picks but high shipping and sorting effort. Many lines per order – typical in B2B trade or manufacturing – means longer picking routes but fewer shipping units. These differences influence which picking strategy, warehouse technology, and WMS concept are most appropriate.

In warehouse management systems, orderlines are maintained as data records and serve as the basis for:

  • generating pick orders and pick lists
  • controlling batch or multi-order picking
  • calculating throughput times and picking performance
  • tracing batches and serial numbers at the position level

What to consider during selection and planning

When selecting systems and planning your warehouse, you should carefully analyze the orderline structure of your orders. Relevant factors include: the average number of lines per order, the degree of variation, the proportion of single-line orders, and the distribution across ABC items. These figures feed directly into the sizing of conveyor systems, picking zones, and buffer areas. Vendors of WMS and automation solutions often apply different definitions – for example, whether partial quantities or back-orders count as separate orderlines. You should clarify this explicitly in tenders and comparisons to avoid misunderstandings around performance commitments.

Frequently asked questions
