WHMCS + Quickbooks - How do you registry?

[ehm]

I've been using Quickbooks for many years and just now I start using WHMCS.

Before I use to create the invoices on Quicbooks, it will create an account receivable and then when the client paid I will input the payment and the account receivable goes back to zero.

 

Now, using WHMCS I'm not sure how to do that.

 

Do I have to re-enter invoices, one by one on QB and then do the receivable?

 

Or can I enter an one big invoice with all clients?

 

or how do you do that?

 

I know that would be a question to one accountant, but I don't have one, so I would like to hear fro you guys here how are you doing y our own books.

 

BTW: it's good to know that this is for a USA based corporation.

 

Thank you
