Background: In a rapidly changing competitive environment and increasing customer expectations, an efficient supply chain is a very important success factor. What should be avoided and what should be considered during planning and supply chain management? Is it possible to apply the same solutions to each business model (B2B/ B2C)? The following article presents the perspective of manufacturing companies. In the current situation there is less and less space for companies operating according to only one model. Each company is considering strategies: low profit in B2B models, which due to greater predictability of demand gives lower risk of production planning and omni-channel in B2C models, which by definition are more profitable, but are associated with a higher risk of demand change. The article presents problems and challenges during supply chain management in manufacturing companies that use both business models in the era of e-commerce market.

Methods: Based on the available literature, the problems of supply chain management in B2B and B2C relations are presented. The frequency of their occurrence was surveyed and the level of risk of negative impact on the company and its environment was presented.

Results: The survey identified the challenges and problems that companies face when managing their supply chains, and those that pose the highest and lowest risks.

Conclusions: This article presents the concept of identification of problems and challenges faced by manufacturing companies and models of actions to be applied in order to minimize their effects. The article is two-dimensional, showing a perspective for simple supply chains (B2B) and omni-channel chains (B2C).
