Agents are where your bookings are coming from, and it includes everything from direct bookings, online bookings, and corporate clients. When you add them to Preno, you'll be able to include things like commission types, rates and contact information about that agent. This'll be synchronised with Xero, too, as a contact.
This is one of the first things you'll want to do with a new account.
There are two different Agent types:
Agent Collect - Payment is made at source
Hotel Collect - Payment is made to the accommodation provider
If you have Agents that remove commission at source you can configure the Agent to add the commission back to the total in Preno. This allows commission to be correctly reported. E.g. Expedia Agent Collect
You can access your Agents by clicking on the Agents tab in the top toolbar. From this page, you can see the list of existing agents, import them in from Xero, and manage their contact info.
