Duplicup ‑ Duplicate SKU Sync

Duplicup helps you optimize your store by safely offering duplicate products and variants under multiple listings. Whether you are selling identical items on separate pages, improving SEO, or managing different prices for POS, simply give them the same SKU. Our app creates a shared inventory pool to keep connected inventory in sync across matching SKUs in real-time. No more manual stock updates or overselling, allowing you to confidently expand your product catalog.
