>Hi,

Hello

I don't know exactly what you mean.

> When you post the
>received advance should I book an item recognized in liabilities.

If you receive money in advance of work or services you are going to do 
then it should normally be recorded as income.  Whether the other leg is 
a liability or an asset depends on your arrangement with the other 
party.

...

>Can I use it when it is identified as a liability account.

I think you're asking about allocating payments to invoices.

>Why not use Payable account?

Because that is (if I understand the question) the money you owe people 
and you can't go around cancelling it against money owed to you at 
random.
