If a certain article is currently not available, customers often migrate to online shops. Also long checkout lines demonstrably increase the rate at which purchases are cancelled. The solution: the Unified Commerce Platform’s native product catalog makes it possible to obtain product data and inventory from a wide variety of sources and link them with each other so that sellers always have access to the entire assortment and can quickly find adequate solutions even in out-of-stock situations. In particular, goods that are not available on site can be reordered to the store or delivered directly to the customer’s home. In addition, Click&Collect and Reserve&Collect processes from the online shop can be consistently completed in the store.
