Quantity increment on product page

[mohsen_eslami a]

We are selling tiles as well in our webstore, and tiles are being sold in box or pallet but the unit price is Square meter

I need a function that increases the amount by SQM per BOX increment

You can set minimum order quantity and incremental rate

Actually Magento has a solution itself in advanced inventory in product page But the problem is when someone input a number which violates the correct incremental rate it just show s up an error message, and as the numbers are mainly decimal format , it’ll become annoying to force customer to calculate the numbers

The correct solution is when customer clicks on + it jumps to next correct amount itself

Thank you so much.
The issue is not only having the buttons only as I already have the button as part of Porto template.

The problem is to have the functionality of increasing or decreasing the quantity based on the incremental rate which is already defined in advanced inventory in admin’s page.
