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.

Pre-Order & Back-in-Stock makes it easy to manage pre-sales and notify customers when products are available. Set up pre-orders based on inventory levels or schedule them with start and end dates. Automatically tag orders with labels like “preorder” or “shipping date” and send confirmation emails to customers. For back-in-stock functionality, customers can subscribe to get notified the moment a sold-out product is restocked, helping you recover lost sales and improve customer satisfaction.
