Scale Insights computes refunded units differently for the Refund Rate against other pages.
Refund Rate Page
The refund rate page looks at orders made during the selected date range, and then finds how many of those past orders are refunded.
The image below shows 3,600 units sold from 06-Oct to 04-Nov, and 48 of those sold are refunded.
This page aims to analyze the actual refund rate in a specific period, enabling you to measure your refund rate over time as you continue to improve your product.
Other Sales Page
Other pages compute refunded units based on refunds made during the selected date range, even if the customer made the purchase 1 year ago.
This computation helps project the current P&L by factoring in refund costs incurred.
Example
A customer purchases a product on 1st January and makes a refund on 1st May.
The refund page will reflect the refund on 1st January.
The other sales page will reflect the refund on 1st May.
