What is SIS concept in retail?
Excuse me, could you elaborate on the SIS concept in retail? I'm quite intrigued by this term and would like to understand its significance in the retail industry. Is it a specific marketing strategy, a technological innovation, or perhaps a customer service approach? I'm particularly interested in how it's implemented and what benefits it brings to both retailers and their customers. Can you provide a concise yet informative description of the SIS concept in retail?
