Ideally your CSV file should contain one line per order and run in date order (either oldest to newest, or newest to oldest). If your CSV contains multiple lines per order, our system will handle this automatically for you (taking the first line for each order from your file) but
these lines will count against the order row limit for your account plan. Remember, you can manipulate your CSV file before you upload it if you wish to change the file order or remove any order rows manually yourself.
The essential columns we need to process your file are 'Order ID', 'Order Date', 'Order Value', and 'Customer ID' ('Customer ID' can be any customer identifier, such as the customer email address).
