See every featureOrca uses AI to rapidly turns purchase orders into Shopify products & accurate inventory. Upload a PO as a PDF, spreadsheet, or snap a photo, and Orca reads it into line items, then creates draft products and variants in Shopify—adding barcodes, descriptions, & weights on request. When a shipment arrives, a guided receiving flow updates inventory & flags shortages and overages.
