Definition
This is the product revenue from all the raised invoices excluding any revenue generated from service.
Example
Clinic A has issued three invoices this week:
Invoice 101: $300 for appointments + $50 for products.
Invoice 102: $200 for a physiotherapy session (no products).
Invoice 103: $150 for services + $30 for supplements.
To calculate Total Product Revenue, sum of product sales:
Invoice 101: $50 for products
Invoice 102: none
Invoice 103: $30 for supplements
So, the Total Product Revenue = $50+ $30 = $80.
