Customers etransfer to my business account $100 deposit their booking. They will be deducted from the final bill when they use the service later. What do I do on QBO?

Hello pinpinentertainm,

It's a pleasure to see you in Community.  Welcome!  QuickBooks Online provides the features you need, to manage your books with confidence.  There are a couple of options for receiving deposits from your customers.  I'd be glad to provide more information so you can choose the best fit for your business needs!

One option is to add a deposit field to the customer invoice. This will reduce the total amount and calculate your customer’s balance due.  Another option would be to create a credit memo.  A credit memo can be applied to reduce a customer's current balance, or you can create a delayed credit, to be used in the future. 

If you're not sure which option to apply, I suggest speaking with an accounting professional.  They'll be able to provide their expertise and best course of action, to ensure a positive outcome in your books.  If you don't have an accountant, we can help you locate a ProAdvisor in your local area.

Feel free to reach back out with other questions.  We would be happy to help!
