Can I add void in the invoice which I can calculate the correct invoice balance report?
Can I copy the quotation to invoice divide into 2 or more (deposit and balance) ?
Don’t understand what you mean, sorry.
Yes, but you will have to edit the invoices to show the Deposit and the Outstanding Amount. but this is not the correct way to account for a Deposit - see the guide Record customer deposits and advances
Copy once and edit to represent the deposit.
Copy the quotation again or clone the deposit invoice and edit.
Noting that if you want the deposit to be shown on the balance invoice then that may not occur.
Invoicing for a deposit is okay, that’s different from receiving an unvoiced deposit.
