Tile business needing the option of adding by Square meter or number of tiles

Hi I am building a shopify website selling tiles I want the customer to choose by number of square metres or number of tiles like this website: https://www.tilemountain.co.uk/p/white-marble-split-face-mosaic.html

I know the price of each item by m2 price or tile price. I just need a formula and some filed boxes that adjust the price according to eh number inputted by the customer.

I want to avoid using an app if possible due to monthly cost and server load times

Hi @Everpro-Mick ,

It will be a complicated request and need a lot of steps to check, if you don’t want to install the app, I recommend you to hire a professional for it. Because no one can guide you in detail without testing and debugging it for a long time.

You can hire experts at the group, they will check it for you: https://www.shopify.com/partners/directory

Hope it helps!

hi @Everpro-Mick this can be done via custom coding inside shopify
