FAQ
Which file do I need? The monthly statement CSV: Shop Manager > Finances > Monthly statements > Download CSV. It has Date, Type, Title, Info, Currency, Amount, Fees & Taxes and Net columns.
Does it log in to my shop? No. It reads the CSV you downloaded. Nothing is uploaded and no login or API key is used.
Is this tax advice? No. It organises your own statement. Ask your accountant how to report the figures.
Where do the costs come from? Your own cost list (SKU or item name and unit cost). Items missing from it are named in the summary.
