The IT component is a significant expenditure in e-commerce. The online store needs to ensure the smooth operation of:
• The showcase where the goods will be displayed and orders will be received i.e., the online store itself
• The system for processing product content (PIM)
• The system for processing orders (OMS)
• Services for advertising support: online marketing, newsletters, and customer communications (CRM, messengers, chatbots, etc.)
And this is just the bare minimum of functions requiring support.
In offline retail, the store itself serves as the showcase, product content is only needed for accounting, and order processing is done at the cash register.
