Optionfier

Custom product options, bundles, and inventory management for Shopify.

Add text fields, file uploads, color pickers, date selectors, and more to any product page — beyond what Shopify variants can do. Optionfier handles inventory automatically, whether you use native bundles or line item properties.

• Dropdowns, swatches, checkboxes, text inputs, date pickers, file uploads
• Bundle mode with automatic inventory deduction at checkout
• Conditional visibility — show options based on other selections
• Inventory-only groups for kits and gift boxes
