Product Options Lab

Product Options Lab adds unlimited custom options to your Shopify products, turning them into personalized, made-to-order experiences. Add text fields, dropdowns, checkboxes, swatches, file uploads, dates, quantities, and measurements to any product. Calculate custom option charges by dimension, weight, volume, formula, fixed rate, or percentage. Customers see a live preview of their personalization directly on the product photo. Custom charges apply automatically at checkout with no separate line items. Build options once and reuse them across multiple products. Perfect for made-to-measure items, this app reduces reliance on complex Shopify variants while increasing personalization. View every customer's exact selections and uploaded files on each order. Add conditional logic for smarter, guided customization that helps customers configure products correctly.
