The Comparison report shows how your products do from 1 period to the next. Use it to spot trends. For example, sales went up 20% in week 1, up 25% in week 2, then dropped 7%.
It also helps you see what changed things. A lower price may sell more units but earn less per sale. More ad spend may lift sales but cut profit.
Read the report
First column: the product.
Second column: what's being measured, like Sales or Profit. Click the plus sign next to a product to see more rows for it. Use Expand All or Collapse All to open or close every product.
The other columns: 1 for each date range. Click a date column header to sort by it.
Change the dates
By default, the report shows the last 4 weeks, 1 week per column. To change it, click the date box. Pick From and To dates and how to split them (Year, Quarter, Month, Week, Day or Custom), then click Set Date.
Example: compare Black Fridays.
Pick this year's Black Friday as From and To.
Tick "Compare to another date range".
Pick last year's Black Friday.
Click Set Date, then Run Report.
See How to view a Profit and Loss Comparison Report for the full steps.
Pick transaction types
By default, all types are included: orders, refunds, adjustments and more. To see only some, click the Type dropdown (it shows "Type: All") and untick the ones you don't want.
Choose which rows to show
Click Columns to pick what's measured for each product, like Sales, Profit or Profit Per Item. Click the star next to one to make it the row you see when a product is closed. Click "Reset to default" to start over.
For example, star Profit Per Item, and that's what each product shows first.
