standing order; continuous order
Used in business and computing contexts for an order that repeats automatically or is maintained over time, such as subscription-based ordering or automated replenishment.
In this system, a standing order is automatically placed when inventory runs low.
It's more efficient to switch consumables to a continuous order.
定期発注 refers to orders placed at fixed intervals (e.g., weekly), while 継続発注 emphasizes an ongoing, often automated, order relationship without a strict schedule.
Compound of 継続 (continuation) and 発注 (ordering). The exact historical derivation is uncertain, but the meaning is transparent from its components.
