Globo Product Options, Variant

Shopify caps you at 2,048 variants per product. Globo removes the cap. Build option sets from 30+ field types - text, file upload, colour and image swatches, dropdowns, dates and dimensions - and apply them to one product or the whole catalogue. Charge extra for options that cost more: add-on pricing runs on Shopify Functions, so discount codes and taxes stay accurate. Conditional logic hides options until they are relevant, and every choice flows into orders, packing slips and POS.
