We have developed a simple NETO API that allows you to calculate the gross profit margin of multiple products in a NETO POS sales order.

This extension is completely free and open-source.

How to use it:

• Click the extension icon on the product selection screen.
• Select the products you want to calculate the gross profit margin.
• Select a product category if you wish to calculate it on more than one product.
• Check if the product prices are missing.
• Check the accuracy status of the calculation.
