Nozzle updates its data on a daily basis. Part of this process requires going back in time to capture changes Amazon has made after a particular event has taken place such as an order placed.
For instance:
Every day we go back over the last 10 days to capture all sales that have moved from a "pending" status to a "shipped" status.
Up to 3% of the time, there's no unique identifier associated with an order. Over the next 30 days after an order, Amazon will populate this field and Nozzle will update its data. This means that some metrics like new-to-brand customers or repeat customers (and metrics that rely on them) are subject to change up to 30 days after an order is placed. However it's generally small number (mostly around 0.5% of orders but up to 3%) so in the vast majority of cases, this won't affect the interperetation of the charts and data.
Click andf ad sales attribution are subject to change up to 72 hours (3 days) after the click/sale event takes place so this data may change up to 3 days after the event.
There may be small changes to other datasets but these will not affect the charts in a material way.
