Looking for historical data on sales back 3+ years

Hi,
Orders older than 1/1/2016 are only available through Archived Order Reports

For newer sales/orders see Order Reports and All Orders Report. Pro accounts only.
For sellers on the individual selling plan you can customise the date range in Manage Orders to find records of older sales.
