A time window is the time range when you intend to fulfill an order. Therefore, an order is considered fulfilled on time if it arrives within the time window. The time window is set when you schedule an order in Bringg and is usually defined by the no_earlier_than and no_later_than fields. Narrower time windows are seen as better service, like 9 to 10 am, while longer windows are more typical of larger carriers.
You can share the time window with your consumers for an improved experience. For example, if a consumer places an order for the 8:00-12:00 the following day, in the morning notify them that you intend to arrive between 8:00-9:00.
If you allow consumers to select their preferred delivery slot, the time window is scheduled accordingly.
