BellOur CRM export of customer orders (355 rows) came from the web shop, the phone team and the marketplace, and some orders were imported more than once. Clean it up so every real customer order appears exactly once. The sheet is long and only opens 50 rows a page; payments, legal holds and earlier reviews are in each row's history. The finance team left notes that define what counts as a duplicate and how duplicates must be resolved: read them first and follow them exactly.
