The McKesson case illustrates the problem directly: printed catalogs are obsolete the moment they leave the press—pharmacists receive lists that may be inaccurate weeks old. The solution is to move the catalog online so inventory status and product availability update in real time—buyers always see current data, not a printed version from months ago. Beyond immediacy, online catalogs enable what print cannot: buyers can check their order history, one-click repeat their last purchase list, see pricing tailored to them. Together, these features cut McKesson pharmacies' average ordering time by 90%. For export-focused companies, the logic is the same: centralize product data management and show connected buyers real-time information to make your catalog truly effective.
