Estimated Delivery Dates (EDDs) must be built on data — not assumptions.
In simple terms, EDDs depend on three key factors:
EDD = Courier SLA + Origin–destination transit time + Fulfilment lead time
The smart approach is to start conservative, continuously measure actual delivery performance,
and then shorten EDDs confidently as your data becomes more reliable.
