The EBK system that BookingMeta provides for your suppliers is sufficient to meet your supplier's business needs. However, if the supplier is not satisfied that the system can only accept orders from one of your agents, but also wants orders from other agents to be processed on the system, then the EBK system, which focuses on managing orders, will not be sufficient and the supplier will need to list items on the system.
At this point, you can suggest that your supplier also contact BookingMeta to become a user of the main system, so that the supplier can use BookingMeta to list items and take more orders.
There are many benefits for you to have your suppliers use BookingMeta, see:Inner API technology to interface with suppliers.
