Helps me collate my Amazon purchases for expensing.
The order export and organisation makes it much easier for me to manage my expense requests and for the end of financial year tax returns.
I like that it exports easily to a CSV file or Excel and I can import it into my accounting software pretty easily, or attach the file to my expense claims. I used to have to do this by hand which took a long time especially in the months where I would order a lot.
I wish that they would support a single account plan because I only have 1 amazon account, and I wish they supported other store regions too.
