One of the biggest problems for multichannel eCommerce businesses is managing inventory and order fulfilment across multiple channels. This can be challenging because each channel may have different inventory levels, shipping requirements, and fulfilment processes.
In addition, it can be difficult to ensure consistent branding and customer experience across multiple channels, as each platform may have different design and layout options. Another challenge is managing customer service and returns across multiple channels, as customers may expect different levels of support and return policies may vary between platforms.
