HBN: Online Availability explains why a product that looks in stock still cannot be bought. It checks product status, Online Store and Market publication, sellable inventory, fulfillment locations, delivery profiles, and shipping-rate coverage for the target country. Each finding identifies the step preventing purchase and shows the relevant Shopify values. Available workflows include repeated scans, multiple target policies, preflight checks, controlled fixes, and activity logs.
