Purpose – The purpose of this paper is to identify the realignment of the physical distribution process for store-based retailers in their efforts to integrate the online channel into their business model. Multiple attributes of the physical distribution process are evaluated to identify associations with order fulfillment methods adopted by omni-channel retailers. Design/methodology/approach – A multi-method approach is used which includes qualitative evaluation of 50 interviews of supply chain executives from large retailers. Additionally, secondary data about firm size, store and distribution networks, online sales, distribution configuration, and order delivery options are used. The findings of qualitative analysis are incorporated into a quantitative classification-tree analysis to identify associations among distribution attributes, order fulfillment methods and order delivery services. Findings – Retailers are developing a consistent omni-channel physical distribution process in which stores undertake a bigger role in order fulfillment and delivery. Level of online sales, size of distribution network, number of sales associates at a store, and number of years engaged in the online channel are identified as having strong associations with the type of order fulfillment method used by omni-channel retailers. The study finds that retailers are focussed on integrating their store and DC inventories and have the benefit of scale with a large store network. Practical implications – Retailers are reconfiguring their physical distribution processes in the complex omni-channel environment can use the findings of this study to evaluate their strategy and identify the level of realignment effort that is needed. A better understanding of the requirements of physical distribution in an omni-channel setting will guide retailers in developing requisite operational capabilities. Originality/value – This paper provides a first in-depth look at order fulfillment choices in omni-channel retail and identifies efforts that are underway to realign key elements of the physical distribution process.
