I work in a small incoming tour operating company. We pay bills to our suppliers (hotels, restaurants, etc). At the end of every month we get the confirmations of services rendered to our clients. Usually there are some corrections of amounts.

For ex:

We pay to hotel as per a bill 10 000 USD for 10 people.

Only 8 people arrived (2 people cancelled their trip)

At the end of the month we get a confirmation from hotel that 2000 is remaining in hotel as our deposit for the next bookings.

In our case we consider that first we pay 10 000 of DEPOSIT to supplier (it is not still an expense)

Second: we get confirmation of rendered services from hotel.

Only after that we can "deduct" 8000 and expenses. In this case we shall see that our deposit is 2000

How can I track such balance in Zoho Books?

Sorry if my question is not "very professional", I'm very new to accounting but I have to track expenses in my small company :)

Thank you!
