Is it possible to record deposit in an estimate and this deposit will be recognised as unearned revenue under current liabilities in QuickBooks?

It's nice to see you here in the Community, usernyabetazy.

Recording deposit in an estimate isn't currently an option in QuickBooks Online. You might want to record it as a retainer.

This transaction is treated as a liability to show that, although your business is holding the money from a deposit, it doesn't belong to you until it's used to pay for services.

Here's how: Step 1. Create a liability account:

1. 1. Select Settings ⚙, then select Chart of Accounts.
   2. Select New.
   3. From the Account Type ▼ drop-down menu, select Other Current Liabilities.
   4. From the Detail Type ▼ drop-down menu, Client Trust Accounts - Liabilities.
   5. Enter a name for the account (ex.  Trust Liabilities) or accept the suggested name.
2. Select an option from the When do you want to start tracking your finances from the is account in QuickBooks? drop-down list.
3. Select Save and close.

Step 2. Create a retainer item:

1. Select Settings ⚙, then select Products and Services.
2. Select New.
3. From the Product/Service information panel, select Service.
4. Enter a name for the new product or service item (ex. Retainer).
5. From the Income account ▼ drop-down menu, select Trust Liability Account.
6. Select Save and close.
