Hi,
You can click on the "export" button of the HikaShop orders listing in order to get a CSV of your sales.
Then, Sage Businessworks has an import system for the sales. The issue is that the format will be a bit different.
So it will require opening the CSV in excel (or another CSV edition software) to modify at least the headers of the data columns.
The export could be customized in order to do that automatically for you. If you need a developer to work on that for you, I would recommend contacting our partners:
