Effective Tour has a powerful feature of working with offline travel agents, in a way very similar to an OTA. As you might know, you can connect any agent and provide them separate rates and gives full access to your rates and inventory.
To make this cooperation more similar to the OTA, we create the access rights which you, as a hotelier can setup for each connected agent. So you can decide what the agent can actually do. Only view the availability of the rooms, allow them to hold the rooms or even do the immediate booking same as Booking/Agoda/Expedia did.
