Update order price of a product

How can I make the price of a product update based on whether the customer enters the specifications they want for their product in a field in the online store. For example: A functionality that allows users to calculate the price per square meter of a product. This would facilitate the quoting and purchasing process, giving customers an accurate cost estimate based on their specific needs.

I was thinking of doing it through the Shopify application or the Shopify API, but if you can provide me with some documentation that I can follow or any idea on how I could do it, please. I am a web programmer. Currently I only make shopify web templates.

Hi @Lionelriv ,
This is Theodore from PageFly - Shopify Page Builder App.

You can achieve dynamic product pricing based on customer input in your Shopify store! Here are two methods:

1. Product Variants (Simple):

  • Best for limited option sets (size, material).
  • Create variants in Shopify for each combination (e.g., size S, material X = $Y).
  • Customers choose the variant matching their needs at checkout.
  • No coding required.

2. Product Options Apps (Complex):

  • Ideal for complex pricing variations (price per sq. meter).
  • Use Shopify apps like Bold Product Options, POWR Variant Options, or ShopPad Infinite Options.
  • Create custom options for customers to enter specifications (e.g., dimensions).
  • The app calculates price based on your rules (price per sq. meter).
  • Final price updates dynamically on the product page.
  • Some apps might involve code for advanced calculations (your web dev skills come in handy!).
