If you get an error on your import that says "Transactions is invalid', 'transactions Amount must be greater than zero for sale transactions", this means the value you mapped for the transactions.amount field on the Transactions tab in the data mapping is less than or equal to 0.

Shopify does not allow you to import orders that have a transaction value less than 0.

To fix this error you'll need to make sure the data in the column you mapped to the transactions.amount Shopify field is great than 0. We are working on an update that will allow you to add a 0 or blank field for the transactions.amount field.
